What happens to water molecules when a large quantity of thermal energy is added to water in the liquid state? A The water molecules become packed closer together, and their temperature increases. B Each water molecule gives up kinetic energy and eventually stops moving. The molecules gain kinetic energy, move farther apart, and become a gas. D The more thermal energy added, the greater the attraction between molecules.​

answer; i believe the correct answer is (solid gold);

answer; protein;

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
