N2 (g) + 3H2 (g) -->2 NH3 (g) The equation above is the equation for the Haber process. In a certain reaction, you start with 3.0 moles of nitrogen and 5.0 moles of hydrogen, How much of the excess reactant will be left over after the reaction?
H₂ is in excess and N₂ will be completely consumed in the reaction.
Explanation:According to the balanced equation, 1 mole of N₂ reacts with 3 moles of H₂ to produce 2 moles of NH₃. In this particular reaction, you have 3.0 moles of N₂ and 5.0 moles of H₂. To determine the limiting reactant, you need to compare the moles of each reactant to the stoichiometric ratio. In this case, the ratio of moles of N₂ to H₂ is 1:3. Since you have more moles of H₂ (5.0) compared to the stoichiometric ratio, H₂ is in excess. Therefore, all of the N₂ will be completely consumed and there will be no N₂ left over after the reaction.

Which nuclear emission has the greatest penetrating power?
b. beta particle
a. proton
c. gamma radiation
d. positron
Answer:gamma radiation
Explanation:
Among the nuclear emissions including proton, beta particle, positron and gamma radiation, gamma radiation has the greatest penetrating power. It needs dense materials like lead or concrete to be shielded.
Explanation:Of the nuclear emissions listed: a. proton, b. beta particle, c. gamma radiation, and d. positron, the one with the greatest penetrating power is c. gamma radiation. Unlike other particles, gamma radiation is a type of electromagnetic radiation, similar to X-rays. This means it is not a charged particle, allowing it to penetrate materials more easily.
For instance, alpha and beta particles would be blocked by a piece of paper or the surface of the human skin, but gamma rays can penetrate much deeper, requiring dense materials like lead or concrete for shielding.

What number of moles of solute are present in 25.0 mL of 2.00 M HCl?
The number of moles of solute that are present in 25.0 mL of 2.00 M HCl is equal to 0.05 moles.
How do we calculate moles from molarity?Molarity (M) of any solution is define as the number of moles (n) of solute present in per liter of the solution (V) and represented as:
M = n/V
Given that, Volume of solution = 25mL = 0.025L
Molarity of HCl = 2M
Moles = (2)(0.025) = 0.05 moles
Hence required moles of solute are 0.05 moles.

A ping pong ball with a dent in it can be put into a pan of boiling water. After a short amount of time, the dent will pop out. Explain why this occurs.
Answer:
The right option is; b. the water caused an increase in temperature of the air inside the ball and an increase in pressure.
The dent (hollow area formed by pressing or hitting) from the ping-pong ball disappeared because energy was transferred from the hot boiling water in which the ball was placed to the air inside the ball. This transferred energy will increase the temperature of the air inside the ball and the air molecules will begin to move faster with a greater force. Hence, causing an increase in pressure.

Number of moles in 11.82 g gold
Final answer:
The number of moles in 11.82 g of gold is calculated by dividing the mass of the gold by its molar mass. The atomic weight of gold is approximately 197 g/mol, so the calculation is 11.82 g divided by 197 g/mol.
Explanation:
The calculation of the number of moles in a given mass of a substance is a fundamental concept in chemistry. The number of moles (n) can be determined using the formula:
n = mass (g) / molar mass (g/mol)
For gold (Au), the atomic weight is approximately 197 g/mol, which is its molar mass. Therefore, to find the number of moles in 11.82 g of gold, you divide the mass of the gold by the molar mass of gold as follows:
n = 11.82 g / 197 g/mol
This calculation will give you the number of moles of gold in the sample. The density of gold and Avogadro's number are not directly needed for this calculation, but they are commonly referenced when discussing the properties of elements and the mole concept.
How many moles of KNO3 are needed to make 600 ml of a 1.3M solution?
To make a 1.3M solution with a volume of 600 ml, you would need 0.78 moles of KNO3.
Explanation:To calculate the number of moles of KNO3 needed to make a 1.3M solution, we can use the equation:
Molarity (M) = moles of solute / liters of solution
Rearranging the equation, we can solve for moles of solute:
Moles of solute = Molarity x liters of solution
In this case, the molarity is 1.3M and the volume is 600 ml (which is equivalent to 0.6 L). Substituting these values into the equation:
Moles of KNO3 = 1.3M x 0.6 L = 0.78 moles

Why can 6-aminohexanoic acid undergo a polymerization reaction with itself?
Answer: Functional groups can lead to intra molecular condensation.
Explanation: 6 -aminohexanoic acid is a molecule which have 2 functional groups - one is amine group (-NH2) and the other one is carboxylic group (-COOH).
The non bonding electrons or lone pairs present on the amine group being nucleophillic in nature will attack on the electrophillic carbon of carboxylic group to form the amide bond, the structure of which is hereby attached.
Thus due to the presence of 2 active functional groups, polymerization with itself can take place easily.
A sample of oxygen gas has a volume of 150. milliliters at 300 k. if the pressure of the sample is held constant and the temperature is raised to 600 k, the new volume of the sample will be
Answer:
The new volume of the sample will be 300 milliliteres
Explanation:
We were given the following;
Initial Volume (V1) = 150ml
Initial Temperature (T1) = 300K
Final Temperature (T2) = 600K
Final Volume (V2) = ?
Pressure is held constant.
The law applicable in solving this question is that of Charle's law. This law states that the volume of a fixed mass of gas varies proportional to the temperature at constant pressure.
The formula is given as;
[tex]\frac{V1 }{T1} = \frac{V2 }{T2}[/tex]
Solving for V2. we have;
[tex]V2 = \frac{V1T2}{T1}[/tex]
V2 = ( 150 * 600) / 300
V2 = 300 ml

Krypton-79 has a half-life of 35 hours. how many half-lives have passed after 105 hours?
Three half-lives of Krypton-79, which has a half-life of 35 hours, have passed after a period of 105 hours.
Explanation:The concept underlying the question is related to the half-life of a radioactive substance. The half-life is the amount of time it takes for half of the substance to decay. Therefore, in the situation described in the question, the half-life of Krypton-79 is 35 hours.
If we have a time period of 105 hours, we can find the number of half-lives that have passed by dividing the total time by the half-life. So, 105 hours divided by 35 hours per half-life equals 3.
Therefore, 3 half-lives have passed in 105 hours for Krypton-79.

Why do covalent compounds tend to have lower melting points than ionic compounds?
The forces of attraction in covalent compounds are weaker than those in ionic compounds as they are formed by sharing of electrons.
What are covalent compounds?Covalent compound is defined as a compound which is formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.
Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent bonding involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.
Sigma bonds are the strongest covalent bonds while the pi bonds are weaker covalent bonds .Covalent bonds are affected by electronegativities of the atoms present in the molecules.Compounds having covalent bonds have lower melting points as compared to those with ionic bonds.

The pair of elements that forms a bond with the least ionic character is
A. Na and Cl
B. K and Cl
C. O and Cl
D. Mg and Cl
The pair of O and Cl elements forms a bond with the least ionic character.
The ionic character of the bond depends on the electronegativity difference. The bonds having an electronegativity difference of greater than 1.7 have more ionic character.
(A) In bond between Na and Cl, the electronegativity difference =
Electronegativity of Cl - electronegativity of Na
= 3.16 - 0.93
= 2.23
(B) In bond between K and Cl
= electronegativity of Cl - electronegativity of K
= 3.16 - 0.82
= 2.34
(C) In bond between O and Cl:
= electronegativity of O - electronegativity of Cl
= 3.44 - 3.16
= 0.17
(D) In bond between Mg and Cl:
= electronegativity of Cl - electronegativity of Mg
= 3.16 - 1.31
= 1.85
Since the bond between O and Cl has the least electronegativity difference, thus have the least ionic character.
