Whenever energy is converted from one form to another, some of that energy is lost by being changed into heat.
In a chemical equation, a subscript tells one how many atoms or molecules of a reactant or a product take part in a reaction.
Na₃PO₄ -----> 3Na(+) + PO₄(3-)
y-y.......................3y...........y
3y = 1.2
y = 0,4M
Na₃PO₄ -----> 3Na(+) + PO₄(3-)
0,4-0,4..............1,2..........0,4
0.........................1,2..........0,4
C = n/V
n = C×V
n = 0,4×0,65L
n = 0,26 mol Na₃PO₄
mNa₃PO₄: (23×3)+31+(16×4) = 164 g/mol
164g ----- 1 mol
Xg -------- 0,26 mol
X = 164×0,26
X = 42,64g Na₂SO₄
This is the actual answer

Answer:
The total mass of reactants equals the total mass of products
Step-by-step explanation:
The <em>Law of Conservation of Mass</em> states that matter cannot be created or destroyed in a chemical reaction:
Reactants ⟶ products
Thus, if you start with a given mass of reactants, the total mass of products will equal the total mass of reactants.
