Which chemical symbols will complete the equation for this single displacement reaction? 2nabr + cl2 → 2 + you in advance

2NaCl + Br2

This is because Na (Sodium) still needs to retain the coefficient or amount of two. Since Chlorine already has 2 on the reactants side, having a two in front would make sense so both elements can have a two.

Bromine would have the subscript of two as in the reactants side of the equation, it is also under the coefficient of two. Thus, it would need to carry it to the products side in order to keep the equation balanced.

Hope this helps!

The chemical equation for the given reaction is given below.

Explanation:

A single displacement reaction is defined as the reaction in which more reactive element displaces the less reactive element from its chemical reaction.

Element A is more reactive than element B.

The chemical equation for the reaction of sodium bromide with chlorine gas follows:

By Stoichiometry of the reaction:

2 moles of sodium bromide reacts with 1 mole of chlorine to produce 2 moles of sodium chloride and 1 mole of bromine gas.

a chemical reaction

explanation:

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
