All of them are right except the neutron one. The neutrons is actually 176 because you subtract the number of protons from the atomic mass to find this.
Answer:
Neither side is favored
Explanation:
In a reaction at equilibrium in which reactants and products are gases, pressure is a factor that produces a shift of the equilibrium position. When the pressure is increased, the equilibrium is shifted to the side of the reaction with a fewer moles. In this reaction:
2 HD(g) ⇀↽ H₂(g) + D₂(g)
There is the same number of moles on both sides:
reactants side: 2 moles HD
products side: 1 mol H₂ + 1 mol D₂ = 2 moles
Therefore, the equilibrium position will not change.
Answer:
magnesium (Mg)
Explanation:
Both are in group 2 and because of that share the same chemical properties.
