Answer:
Mass of HCl = 73 g
Explanation:
Given data:
Mass of hydrogen = 2 g
Mass of HCl = ?
Solution:
First of all we will write the balance chemical equation:
H₂ + Cl₂ → 2HCl
Number of moles of hydrogen = 2 g/ 2g/mol
Number of moles of hydrogen = 1 mol
Form balanced chemical equation compare the moles hydrogen with HCl.
H₂ : HCl
1 : 2
Mass of HCl:
Mass of HCl = number of moles × molar mass
Mass of HCl = 2 mol × 36.5 g/mol
Mass of HCl = 73 g

Answer: increase pressure and decrease temperature.
Explanation:
Increasing pressure uses force to make the gas molecules come closer together. (Decreasing pressure allows the molecules to spread out) Decreasing temperature will also cause the molecules of gas to come together closer. (Heat excites molecules causing them to spread out and therefore expand)
Answer:
metals and nonmetal ions
Explanation:
Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when electrons are shared between two nonmetals. An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
