The equilibrium position will shift in order to counterbalance the change. That means the equilibrium position will shift, lowering the pressure once more.... When the pressure on a gas reaction is increased, the equilibrium moves to the side with fewer molecules.
Koby needed to break the baking soda to provide a larger surface area for reaction thereby increasing the rate of reaction.
<h3>Rate of reaction?</h3>
The term rate of reaction refers to how quickly or slowly a reaction proceeds. The surface area of solid reactants is an important factor that influences the rate of reactions when a solid reactant is involved.
Hence, Koby needed to break the baking soda to provide a larger surface area for reaction thereby increasing the rate of reaction.

Answer is: a) ionization energy and electronegativity.
1) The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).
Barium, potassium and arsenic are metals (easily lost valence electrons), chlorine is nonmetal (easily gain electrons).
Alkaline metals (far left in Periodic table) have lowest ionizations energy and easy remove valence electrons (one electron), earth alkaline metals (next right to alkaline metals) have higher ionization energy than alkaline metals, because they have two valence electrons.
Nonmetals are far right in the main group and they have highest ionization energy, because they have many valence electrons.
2) Electronegativity (χ) is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.
Atoms with higher electronegativity attracts more electrons towards it, electrons are closer to that atom.
Nonmetals hava higher electronegativity than metals and metalloids.
3) The atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
Using the Boyle's law, the volume of the gas at 15 Km is .
<h3>What is Boyle's law?</h3>
Boyle's law states that, the volume of given mass of gas is inversely proportional to its pressure at constant temperature. Since pressure decreases with height, the volume will increase at higher altitude.
Initial volume = 10.0
Initial pressure = 1.00 atm
Final pressure = 0.350 atm
Final volume = ?
Using;
P1V1 = P2V2
V2 =
V2 =
V2 =
