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.

Formic acid, from the Latin formica, is the acid present in ants sting. What is the
concentration of HCOO" at equilibrium if the initial concentration of formic acid,
HCOOH, is 1.35 M (Kg = 1.7 x 10-4).
For the reaction of deprotonation of formic acid, the concentration of HCOO⁻ at equilibrium is 0.0151 M if the initial concentration of formic acid is 1.35 M.
The reaction of deprotonation of formic acid is the following:
CHOOH + H₂O ⇄ HCOO⁻ + H₃O⁺
At the equilibrium we have:
CHOOH + H₂O ⇄ HCOO⁻ + H₃O⁺ (1)
1.35 - x x x
The acid equilibrium constant for this reaction is:
[tex] K_{a} = \frac{[HCOO^{-}][H_{3}O^{+}]}{[CHOOH]} = 1.7 \cdot 10^{-4} [/tex] (2)
Entering the values of [CHOOH] = 1.35-x, [HCOO⁻] = [H₃O⁺] = x, into equation (2) we have:
[tex] 1.7 \cdot 10^{-4} = \frac{[HCOO^{-}][H_{3}O^{+}]}{[CHOOH]} = \frac{x^{2}}{(1.35 - x)} [/tex]
[tex]1.7 \cdot 10^{-4}(1.35 - x) - x^{2} = 0[/tex]
After solving the above quadratic equation and taking the positive value for x (concentrations cannot be negative), we have:
[tex] x = [HCOO^{-}] = [H_{3}O^{+}] = 0.0151 M [/tex]
Therefore, the concentration of HCOO⁻ at equilibrium is 0.0151 M.

What is the process whereby stars create elements heavier than hydrogen?
atomic growing
atom splitting
nucleosynthesis
hydrogenation
Answer:
nucleosynthesis
Explanation:
The correct answer is nucleosynthesis.
How do stars create heavier elements?After the hydrogen in the star's core is exhausted, the star can fuse helium to form progressively heavier elements, carbon and oxygen, and so on, until iron and nickel are formed. Up to this point, the fusion process releases energy. The formation of elements heavier than iron and nickel requires an input of energy.
What was the process of the formation of heavy elements?In a supernova explosion, neutron capture reactions take place (this is not fusion), leading to the formation of heavy elements. This is the reason why it is said that most of the stuff that we see around us comes from stars and supernovae (the heavy elements part).

when an electron moves from a higher orbit to a lower one does it always follow the same path explained
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.

if 0.400 moles CO and 0.400 moles O2 completely react how many grams of CO2 are produces?
2CO+O2 becomes 2CO2
If 0.400 moles CO and 0.400 moles O2 completely react, 17.604 grams of CO2 would be produced.
First, let us look at the balanced equation of reaction:
[tex]2CO + O_2 ---> 2CO_2[/tex]
According to the equation, the mole ratio of CO and O2 is 2:1. But in reality, the mole ratio supplied is 1:1. Thus, CO is the limiting reactant while O2 is in excess.
Also from the equation, the ratio of CO consumed to that of CO2 produced is 1:1. Thus, 0.400 moles of CO2 would also be produced from 0.400 moles of CO.
Recall that: mole = mass/molar mass
Therefore, the mass in grams of CO2 that would be produced from 0.400 moles can be calculated as:
Mass = mole x molar mass
= 0.400 x 44.01
= 17.604 grams

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.
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.
