Write the balanced net ionic equation for the reaction that occurs in the following case: cr2(so4)3(aq)+(nh4)2co3(aq)→ express your answer as a balanced net ionic equation. identify all of the phases in your answer.

Explanation:

The chemical reaction equation will be as follows.

In the form of ions, reaction equation will be as follows.

Now, cancelling the spectator ions, the net reaction equation will be as follows.

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
