When a substance such as salt is dissolved in water, it is said to enter into the state.

liquid

Explanation:

The salt that is NaCl consists of positive sodium ions and negative chloride ions. The positive sodium will be attracted by the negative oxygen ion of the water molecule and the negative chloride ion will be attracted by the positive hydrogen ion. Thus the solid NaCl salt will be dissolved in water. Thus it will enter into the liquid state.

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
