The heat produced by hydrolysis of 65 kg of ATP is -6.8 kJ.
Let's consider the thermochemical equation for the hydrolysis of ATP.
ATP + H₂O ⇒ ADP + Pi ΔG = -57 kJ/mol
We will convert 65 kg of ATP to moles using its molecular weight (507.18 g/mol).
[tex]65 \times 10^{3} g \times \frac{1mol}{507.18g} = 1.2 \times 10^{2} mol[/tex]
57 kJ of heat are released by the hydrolysis of 1 mole of ATP. The heat released by the hydrolysis of 1.2 × 10² moles of ATP is:
[tex]1.2 \times 10^{2} mol \times \frac{(-57kJ)}{1mol} = -6.8 \times 10^{3} J = -6.8 kJ[/tex]
-6.8 kJ is the heat produced by hydrolysis of 65 kg of ATP.

Answer:Full moon
Hope this helps :)
A lunar eclipse can occur only at full moon.
Explanation:
During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. A total lunar eclipse occurs when the Moon and Sun are on opposite sides of Earth. A partial lunar eclipse happens when only part of Earth's shadow covers the Moon.
Answer:
"Full moon"
A full moon would be needed due to the fact that the sun would need to entirely block it, resulting in a solar eclipse. Hence, the answer is "Full moon".
when an electron moves from a higher orbit to a lower one does it always follow the same path explained
Answers
Yes, electron follows the same path when it absorb and loses energy.
Yes, when an electron moves from a higher orbit to a lower orbit it always follow the same path as it moves from a lower orbit to a higher orbit. When electron absorb energy it has the power to move from lower orbit to higher orbit or energy level.
While on the other hand, when an electron loses that energy, it comes back to its original position from which it moves earlier when it absorb energy so we conclude that electron follows the same path when it absorb and loses energy.

Answers
Answer:
A
Explanation:
Its a becuse vinegar and baking soda make carbon dioxide
The equation best models the reaction of vinegar (C2H4O2) and baking soda (NaHCO3) -
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
The overall process can be summarized by the following word equation:
baking soda (sodium bicarbonate) reacts with vinegar (acetic acid) that yields carbon dioxide and water with sodium acetateThe chemical equation for the overall reaction is:NaHCO3 (s) + CH3COOH (l) → CO2(g) + H2O (l) + NaC2H3O2
The chemical reaction actually occurs in two steps. there is a double displacement reaction in which acetic acid in the vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid: NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3 Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:H2CO3 → H2O + CO2
Thus, the equation best models the reaction of vinegar (C2H4O2) and baking soda (NaHCO3) -
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2

Liquid octane CH3(CH2)6CH3 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 3.43 g of octane is mixed with 7.0 g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to significant digits.
Answers
Answer:
88 gram is the answer in 2 significant digits
One mole of octane gives 9 moles of water. Then, 3.43 g or 0.03 moles of octane will give 0.27 moles of water that is 4.86 g of water can be produced.
What is combustion reaction ?Combustion is a type of chemical reaction in which a gas reacts with oxygen to give carbon dioxide and water.
The combustion reaction of octane is given as follows:
[tex]\rm C_{8}H_{18} + \frac{25}{2}O_{2} \rightarrow 8CO_{2} + 9 H_{2}O[/tex]
As per this balanced chemical equation, one mole or 114 g of octane gives 9 moles of water.
no.of moles in 3.4 g of octane = 3.4 g/114 g = 0.03 moles.
no.of moles of water produced from 0.03 moles of octane :
= (0.03 × 9) = 0.27 moles.
Molar mass of water = 18 g/mol
then, mass of 0.27 moles = 0.27 × 18 =4.86 g.
Therefore, the maximum mass of water that could be produced here is 4.86 g.

b = 0.0 L mol-1
Under conditions of very high pressures, what would you predict about the experimental volume of the gas?
The volume would be lower than predicted by the Ideal Gas Law
The volume would be higher than predicted by the Ideal Gas Law
The volume would be exactly the same as predicted by the Ideal Gas Law
Answers
Under conditions of very high pressures, the volume would be lower than predicted by the Ideal Gas Law.
According to the kinetic theory of gases, a gas spreads out to fill the volume of the container holding it. Hence a gas does not have a definite volume due to the fact that there is no inter-molecular interaction between gas molecules.
When the gas is subjected to very high pressure, inter-molecular interactions become significant leading to a decrease in the volume of the gas.
Therefore, when subjected to high pressure, the experimental volume would be lower than predicted by the Ideal Gas Law.
