Answer: Formation of hydrogen iodide will occur.

Explanation:

When molecule of hydrogen gas (H_2) and molecule of iodine gas (I_2) collide with proper orientation and with sufficient amount of energy. This collision of the two different molecules of gases will result in the formation of hydrogen iodide.

The balanced chemical equation of the reaction will written as:

H_2(g)+I_2(g)\righarrow 2HI(g)

The answer to this question would be: chemical changes

When two elements collide, the can react if the structure of the atoms allows it to be combined into a bigger molecule and there is enough energy. In this case, the hydrogen(H2) collides with iodine(I2) would be able to create HI molecule. This change is called chemical changes since it changes the element into a different molecule.

Prove that PV = nRT.​
qaws [65]

Find your answer in the explanation below.

Explanation:

PV = nRT is called the ideal gas equation and its a combination of 3 laws; Charles' law, Boyle's law and Avogadro's law.

According to Boyle's law, at constant temperature, the volume of a gas is inversely proportional to the pressure. i.e V = 1/P

From, Charles' law, we have that volume is directly proportional to the absolute temperature of the gas at constant pressure. i.e V = T

Avogadro's law finally states that equal volume of all gases at the same temperature and pressure contain the same number of molecules. i.e V = n

Combining the 3 Laws together i.e equating volume in all 3 laws, we have

V = nT/P,

V = constant nT/P

(constant = general gas constant = R)

V = RnT/P

by bringing P to the LHS, we have,

PV = nRT.
