Answer:
It determines how the molecule functions.- B.
The shape of a molecule affect the molecule involved in living systems by determining its molecular fractions. The correct answer is B. It determines how the molecule functions.
The shape of a molecule plays a crucial role in how it interacts with other molecules and biological systems. The three-dimensional structure of a molecule determines its chemical properties and how it interacts with receptors, enzymes, proteins, and other molecules within living systems. Here are a few ways in which the shape of a molecule affects its involvement with living systems:
Binding and recognition: The shape of a molecule is important for specific molecular recognition and binding interactions. For example, enzymes bind to specific substrates through complementary shapes, allowing them to catalyze chemical reactions. Similarly, receptors in cells recognize and bind to specific molecules, such as hormones or neurotransmitters, based on their shape.
Biological activity: The shape of a molecule can determine its biological activity. Small changes in the molecular structure, even in the form of stereochemistry or chirality (mirror image isomers), can significantly alter a molecule's biological activity. Enantiomers, which have identical chemical formulas but differ in their three-dimensional arrangement, can have different biological effects due to their distinct interactions with biological systems.
Pharmacokinetics: The shape of a molecule affects its absorption, distribution, metabolism, and excretion within an organism. The size and shape of a drug molecule, for instance, can determine its ability to cross biological barriers, interact with target molecules, and be metabolized or eliminated from the body.

What are repelled in the VSEPR theory?
A. Other molecules
B. Opposite charges
C. Protons in nuclei
D. Electron pairs
Answer:
electron pairs, i just did it on APEX
Explanation:
Final answer:
In VSEPR theory, the elements that are repelled are electron pairs, which include both bonding pairs and lone pairs, dictating the molecular geometry.
Explanation:
The Valence Shell Electron Pair Repulsion (VSEPR) theory predicts the arrangement of electron pairs around each central atom in a molecule. According to this theory, electron pairs are oriented to be as far apart as possible to minimize repulsions. Therefore, the elements that are repelled in VSEPR theory are D. Electron pairs. These include both bonding electron pairs (shared between atoms to make covalent bonds) and lone pairs (non-bonding electron pairs).
In VSEPR theory, the repulsion between electron pairs is a key factor in determining the geometric structure of molecules. For example, in a water molecule (H₂O), the two lone pairs on the oxygen force the hydrogen atoms to adopt a bent arrangement rather than a linear one.
A hot air balloon contains 5.30 kL of helium gas when the temperature is 12°C. At what temperature will the balloon's volume have increased to 6.00 kL? (Remember to convert to Kelvin and then back to Celcius.)
(A) 50 °C
(B) -21 °C
Answer:
(A) 50 °C
Explanation:
Ideal gas law:
PV = nRT
If pressure is held constant, then:
V₁ / T₁ = V₂ / T₂
Substituting values:
(5.30 kL) / (12 + 273 K) = (6.00 kL) / T
T = 323 K
T = 50 °C
Answer:
Option (A) 50 °C
Explanation:
Thinking process:
Let the volume of the hot air be [tex]V_{1}[/tex] 5.30 k l = 5 300 l = 5.3 m³
The initial temperature will be 12 ° (12 + 273.15) = 285.15 K
The later volume, [tex]V_{2}[/tex] = 6 Kl = 6 000 l = 6 m³
The equation will be:
[tex]\frac{P_{1}V_{1} }{T_{1} } = \frac{P_{2}V_{2} }{T_{2} }[/tex]
If the pressure is the same, then:
[tex]\frac{5.3}{285.15} = \frac{6}{T_{2} }[/tex]
Solving for [tex]T_{2}[/tex] gives:
T₂ = 322.8
= 49.66

Which subatomic particle has the least mass?
electron
proton
neutron
nucleus
the answer is electrons
Final answer:
The subatomic particle with the least mass is the electron, having a mass of about 0.00055 amu, which is significantly lighter than both the proton (1.0073 amu) and the neutron (1.0087 amu).
Explanation:
When comparing subatomic particles such as electrons, protons, and neutrons, the electron is the particle with the least mass. Despite all three being crucial components of an atom, an electron has an extremely small mass compared to protons or neutrons. Specifically, the mass of an electron is about 0.00055 amu (atomic mass units), whereas a proton has a mass of approximately 1.0073 amu, and a neutron has a mass of about 1.0087 amu.
Protons and neutrons, collectively known as nucleons, have masses that are nearly identical. However, the neutron is very slightly more massive. The vast difference in mass between electrons and nucleons (protons and neutrons) means that almost all the atomic mass is concentrated in the atom's nucleus, not in the electrons that orbit it.

what is the volume of stank of nitrogen that contains 17 moles of nitrogen at 34 C under 12,000Pa?
Answer:
3626.76dm³
Explanation:
Given parameters:
Number of moles of Nitrogen in tank = 17moles
Temperature of the gas = 34°C
Pressure on the gas = 12000Pa
Unkown:
Volume of the tank, V =?
Converting the parameters to workable units:
We take the temperature from °C to Kelvin
K = 273 + °C = 273 + 34 = 307k
Taking the pressure in Pa to atm:
101325Pa = 1atm
12000Pa = 0.118atm
Solution:
To solve this problem, we employ the use of the ideal gas equation. The ideal gas law combines three gas laws which are the Boyle's law, Charles's law and the Avogadro's law.
It is expressed as PV = nRT
The unknown is the Volume and we make it the subject of the formula
V = [tex]\frac{nRT}{P}[/tex]
Where R is called the gas constant and it is given as 0.082atmdm³mol⁻¹K⁻¹
Therefore V = [tex]\frac{17 x 0.082 x 307 }{0.118}[/tex] = 3626.76dm³
Answer: The volume of nitrogen will be 3614.15 L
Explanation:
To calculate the number of moles, we use the equation given by ideal gas equation:
[tex]PV=nRT[/tex]
Or,
[tex]PV=\frac{m}{M}RT[/tex]
where,
P = pressure of the gas = 12000 Pa = 12 kPa (Conversion factor: 1 kPa = 1000 Pa)
V = Volume of gas = ?
n = number of moles of nitrogen = 17 moles
R = Gas constant = [tex]8.31\text{L kPa }mol^{-1}K^{-1}[/tex]
T = temperature of the gas = [tex]34^oC=[34+273]=307K[/tex]
Putting values in above equation, we get:
[tex]12kPa\times V=17mol\times 8.31\text{L kPa }mol^{-1}K^{-1}\times 307K\\\\V=3614.15L[/tex]
Hence, the volume of nitrogen will be 3614.15 L

Consider the following unbalanced redox reaction:
NO3- → NO
How many water molecules are needed for balancing?
Answer:
I water molexule
Explanation:
equat8n= 2NO3 + h2O =2 HNO3
Final answer:
Upon balancing the redox reaction NO3- → NO, we find that two water molecules (2 H2O) are required for balancing the reaction, ensuring both mass and charge conservation.
Explanation:
The reaction provided, NO3- → NO, is an unbalanced redox reaction. Balancing redox reactions involves ensuring that both the number of atoms of each element and the charge are balanced on both sides of the equation. Let's focus on the nitrogen and oxygen atoms first, and then balance the hydrogen atoms and the charges. After balancing, the fully balanced equation becomes:
NO3- + 2 H+ + e- → NO + 2 H2O
To confirm the balance, verify that there are equal numbers of nitrogen atoms and oxygen atoms on each side of the equation, as well as that the total charge is balanced. Here we can see that there are the same number of nitrogen atoms (1 on each side) and oxygen atoms (3 on the left, 1 in NO, and 2 in the 2 H2O molecules), which means the number of atoms is balanced. Additionally, the total charge on each side is also the same (-1 on the left side with the nitrate ion and the 2 extra positive charges from the hydrogen ions equaling +1, and 0 on the right side with NO being neutral and water having no charge).
Therefore, two water molecules (2 H2O) are required to balance this redox reaction.

CH4 (g) +2 H2S (g) Two arrows stacked on top of each other. The top arrow points to the right. The bottom arrow points to the left. CS2 (g) + 4 H2 (g)
Answer:
Explanation:
The equation of this equilibrium reaction is shown below:
CH₄ + 2H₂S ⇄ CS₂ + 4H₂
All the gases in this reaction are in a gaseous phase.
When gases are in equilibrium with one another, we can make some comments about their particles, concentration and reaction rate.
For the particles:
The magnitude of the kinetic energy here is very great according to the kinetic theory of matter. This is because the particles are in a uniform gaseous phase.
In terms of concentration
When dealing with gases in equilibrium, we talk more of the concentration with regards to pressure. Pressure is equivalent to concentration when we consider gaseous reactions. An increase in pressrue is like applying a stress to the system. Based on Le Chatelier's principle, increase in pressure favors the side with smaller volume:
CH₄ + 2H₂S ⇄ CS₂ + 4H₂
3 moles of gases 5 moles of gases
Increase in pressure will favor the reactant side.
Reaction rate
The rate at which this reaction will proceed would be very fast. This is because gases have the fastest rate of reaction. The equilibrium will quickly be reached.

A. 0.88 atm
B. 0.82 atm
C. 0.073 atm
D. 0.068 atm
Answer:
[tex]\boxed{\text{3.6 atm}}[/tex]
Explanation:
For this question, we must use Dalton's Law of Partial Pressures:
The partial pressure of a gas in a mixture of gases equals its mole fraction times the total pressure:
[tex]p = \chi p_{\text{tot}}[/tex]
1. Calculate the number of moles of each gas.
[tex]n_{\text{CO}_{2}} = \text{35.07 g} \times \dfrac{\text{1 mol}}{\text{44.01 g}} = \text{0.7969 mol}\\\\n_{\text{H}_{2}\text{O}} = \text{27.93 g} \times \dfrac{\text{1 mol}}{\text{18.02 g}} = \text{1.550 mol}\\\\n_{\text{N}_{2}} = \text{12.64 g} \times \dfrac{\text{1 mol}}{\text{14.01 g}} = \text{0.9022 mol}\\\\n_{\text{He}} = \text{5.54 g} \times \dfrac{\text{1 mol}}{\text{4.003 g}} = \text{1.384 mol}[/tex]
2. Calculate the total moles
[tex]n_{\text{tot}} = \text{(0.7969 + 1.550 + 0.9022 + 1.384) mol = 4.633 mol}[/tex]
3. Calculate the mole fraction of helium
[tex]\chi = \dfrac{n_\text{He}}{n_{\text{tot}}} = \dfrac{\text{1.384 mol}}{\text{4.633 mol}}= 0.2987[/tex]
4. Calculate the partial pressure of helium:

Answer:
The partial pressure of He = 3.97 atm
Explanation:
Given:
Mass of CO2 = 35.07 g
Mass of H2O = 27.93 g
Mass of N2 = 12.64 g
Mass of He = 5.54 g
Total pressure P = 12 atm
To determine:
The partial pressure of He
Calculation:
Based on Dalton's law, the partial pressure of a gas can be expressed as a product of its mole fraction and the total pressure
[tex]P(gas)=X(gas)*P(total)-----(1)[/tex]
where X(gas) = mole fraction
[tex]X(gas)=\frac{moles(gas)}{moles(total)}----(2)[/tex]
[tex]Moles(CO2)=\frac{mass(CO2)}{mol.wt.(CO2)}=\frac{35.07g}{44g/mol}=0.7970[/tex]
[tex]Moles(H2O)=\frac{mass(H2O)}{mol.wt.(H2O)}=\frac{27.93g}{18g/mol}=1.552[/tex]
[tex]Moles(N2)=\frac{mass(N2)}{mol.wt.(N2)}=\frac{12.64g}{28g/mol}=0.4514[/tex]
[tex]Moles(He)=\frac{mass(He)}{at.wt.(He)}=\frac{5.54g}{4g/mol}=1.385[/tex]
Therefore:
Moles of He = 1.385
Total moles = 0.7970+1.552+0.4514+1.385 =4.188
Substituting the appropriate values in equation (1) gives:
[tex]P(He)=X(He)*P(total)[/tex]
[tex]P(He)=\frac{1.385}{4.188}*12 atm = 3.97 atm[/tex]
What is true of a covalent bond? (03.03)
It is the electrostatic attraction between oppositely charged particle
It is the sharing of electrons by overlapping orbitals
It involves the exchange of electrons from one atom to another
It involves the sharing of neutrons between two nuclei
Answer:
I think B..
Explanation:
It is the sharing of electrons from one atom to another .
Answer:
The answer is b: It is the sharing of electrons by overlapping orbitals
Explanation:
The ionic bong involves the exchange of electrons from one atom to another to keep eight particles in their outermost orbit. In this way the atoms become stable. This happens between a metal, which losing electrons becomes a cation that now has a positive charge, and a non-metal, which accepting electrons becomes an anion that now has a negative charge. So the ionic bond is the electrostatic attraction between oppositely charged particle (cation and anion).
No chemical bond involves sharing neutrons between two nuclei. Chemical bonds occur between the electrons of atoms, which are found in the outer layer around the nuclei.
So, the correct answer is b: It is the sharing of electrons by overlapping orbitals. This happens between two non-metallic elements.
