Through which of the following processes is carbon directly transferred between living organisms and the environment?
Answers
Answer:
The answer is carbon cycle.
Explanation:
The carbon cycle is an important process for living organisms. As plants prepare their food through photosynthesis and is also an important source of fossil fuels for human activities.
Therefore carbon atoms are regenerated again and again in the carbon cycle process. This recycling process takes place between livings and nonliving things in the environment and also within the earth biosphere.
Abundance supply of carbon is necessary to carry out the biological processes. The entire carbon cycle is actually made up of sourced and sinks elements.

How many moles of BaSO4 are formed if 0.5 moles of Na2 SO4 react with 60 g of BaCl2? Na2 SO4 + BaCl2 → BaSO4 + 2NaCl
Answers
Na₂SO₄ + BaCl₂ ----> 2NaCl + BaSO₄
stoichiometry of Na₂SO₄ to BaCl₂ is 1:1
first we need to find out which the limiting reactant is
limiting reactant is fully used up in the reaction.
number of Na2So4 moles - 0.5 mol number of BaCl2 moles - 60 g / 208 g/mol = 0.288 mol
since molar ratio is 1:1 equal number of moles of both reactants should react with each other
therefore BaCl2 is the limiting reactant and Na2SO4 is in excess. amount of product formed depends on number of limiting reactant present.
stoichiometry of BaCl₂ to BaSO₄ is 1:1.
therefore number of BaSO4 moles formed - 0.288 mol
Answer: 0.29
Explanation:
[tex]Na_2SO_4+BaCl_2\rightarrow BaSO_4+2NaCl[/tex]
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\textMolar mass}}[/tex]
Putting values in above equation, we get:
[tex]\text{Moles of}BaCl_2}=\frac{60g}{208g/mol}=0.29mol[/tex]
Moles of [tex]Na_2SO_4[/tex] = 0.5 moles
According to stochiometry, 1 mole of [tex]BaCl_2[/tex] reacts with 1 mole of [tex]Na_2SO_4[/tex]
Thus 0.29 moles of [tex]BaCl_2[/tex] will react with 0.29 moles of [tex]Na_2SO_4[/tex]
Thus [tex]BaCl_2[/tex] is the limiting reagent as it limits the formation of products and [tex]Na_2SO_4[/tex] is the excess reagent.
1 mole of [tex]BaCl_2[/tex] produces = 1 mole of [tex]BaSO_4[/tex]
0.29 moles of [tex]BaCl_2[/tex] will produce= 0.29 moles of [tex]BaSO_4[/tex]

A (n) blank is a vent or fissure in the earths surface through which magma and gases are expelled
Answers
Answer:
Volcanoes
Explanation:
The volcanoes are the features on the earth's surface through which the magma comes out along with other gases.
The formation of the volcano is associated with the divergent and the convergent type of plate boundary. Due to this motion and subduction of heavier plates, the plates at greater depth melts and mixes up with the uprising magma. This magma then rises up towards the surface in the over-riding plate, forming volcanoes, from where the magma erupts on the surface forming lava along with the emission of various gases such as carbon dioxide, sulfuric acid, and hydrogen sulfate.

2.Electrons carry negative charges and protons carry positive charges. While protons have far more mass the number of protons and electrons in a stable atom is the same. These charges cancel each other out. If there is an imbalanced then the atom is radioactive and decays until it reaches stability.
3.According to the kinetic theory of matter, "All matter is made up of atoms and molecules that are constantly moving. When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases."
What evidence do scientists have that Earth has been hit by large objects, like asteroids, in the past? Check all that apply.
Answers
Answer:
layer of burned organic matter
change in average global temperature
mass extinctions
Explanation:
Asteroids are external rocks/objects that hit the surface of the earth.
Let's check the options:
1- layer of volcanic ash: This option is rejected as volcanoes are caused as a result of the internal heat and combustion in the layers of the earth. Therefore, volcanoes are independent of external bodies as asteroids.
2- layer of burned organic matter: This option is accepted. When bodies , as asteroids, hit the earth, their clash with the earth's surface usually lead to burns and/or fires leading to layers of burnt organic matter that is found on the surface of the earth and its underlying layers.
3- change in average global temperature: This option is accepted as these bodies usually have different temperatures than that of the earth's climate. Therefore, when they penetrate the earth's atmosphere, they can lead to a change in the global temperature.
4- mass extinctions: This option is accepted as the collision of these bodies with the earth's surface can lead to destruction of creatures/objects which may lead to mass extinctions.
5- earthquake activity: This option is rejected as earthquakes are formed as a result of the motion of plates within the layer's of the earth and not as a result of external bodies.

how many liters of laughing gas are in 0.98 moles stp
Answers
3H2 + N2 ===> 2NH3
GIVEN: 44.8 L of H2 at STP.
answer: mols of N2.
By applying ideal gas equation,
[tex]P\times V=n\times R\times T[\tex]
Where, P= pressure of gas
V=volume of gas
R=Gas constant
n=Number of moles of gas
T=Temperature
At STP, each gas has a defined value of pressure, volume and temperature.
P= 1 atm
R=0.0821 L atm mol⁻¹ K⁻¹
T= 0°C or 273 K
Putting all the values in the equation will give:
[tex]1\times V=0.98\times 0.0821\times 273[\tex]
V = 22 L
So the answer is 22 L.

The equation Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g) is an example of which type of reaction?
Answers
Answer : This is an example of single-displacement reaction.
Explanation :
Single-displacement reaction : It is a type of reaction in which the more reactive metal displaces the least reactive metal from its solution.
It is represented as :
[tex]A+BC\rightarrow AC+B[/tex]
where A is the most reactive metal and BC is the compound in which the B is the least reactive metal which is displaced by the most reactive metal A.
The given balanced reaction is,
[tex]Mg(s)+2HCl(aq)\rightarrow MgCl_2(aq)+H_2(g)[/tex]
This reaction is an example of single-displacement reaction in which the magnesium metal displaces the hydrogen metal from its solution to give magnesium chloride and hydrogen gas as a product.
Hence, the given reaction is an example of single-displacement reaction.

the gas left in an used aerosol can is at a pressure of 103 kPa at 25 degrees celsius if this can be thrown into fire what is the pressure of gas when it's temperature reaches 928 degrees Celsius
Answers
The pressure of the gas when it's temperature reaches 928 °C is 3823,36 kPa
To solve that we need to apply Gay-Lussac's Law. It states that the pressure of a gas when the volume is left constant (like in the case of a sealed container like an aerosol can) is proportional to temperature. This is the relationship derived from this law that we use to solve this problem:
[tex]P2= \frac{P1}{T1}*T2= \frac{103 kPa}{25}*928=3823,36 kPa[/tex]
Have a nice day!
Answer:
415.11 kPa
Explanation:
The gas law to be applied here is Gay-Lussac's law. Gay-Lussac's law states that the pressure of a given mass of gas is directly proportional to it's temperature (in kelvin) provided volume remains constant.
The formula for the law is
P₁/T₁ = P₂/T₂
where P₁ is initial pressure (103 kPa)
P₂ is final pressure (unknown)
T₁ is initial temperature (25°C + 273 = 298K)
T₂ is final temperature (928°C + 273 = 1201K)
From the formula,
103/298 = P₂/1201
P₂ = [tex]\frac{103 * 1201}{298}[/tex]
P₂ = 415.11 kPa
415.11 kPa is the pressure of the gas when it temperature reaches 928°C.

HQ5.49 Use standard enthalpies of formation to calculate the standard enthalpy of reaction for the following reaction: 2 H 2 S(g) + 3 O 2 (g) → 2 H 2 O(l) + 2 SO 2 (g) ΔH ∘ rxn
Answers
ΔHf(H₂S) = -20.5 kJ/mol
ΔHf(O₂)=0 kJ/mol.
ΔHf(H₂O) = -285.8 kJ/mol.
ΔHf(SO₂) = -296.8 kJ/mol.
ΔHrxn = ∑ΔHf (products of reaction) - ∑ΔHf (reactants).
ΔHrxn - enthalpy change of chemical reaction.
ΔHf - enthalpy of formation of reactants or products.
ΔHrxn = (2 · (-285,8) + 2 · (-296,8)) - (2 · (-20,5)) · kJ/mol.
ΔHrxn = -1124,2 kJ/mol.
