Answer: There is 842.54 grams of sodium carbonate are produced when 5.3 moles of sodium phosphate reacts with aluminum carbonate.
Explanation:
Chemical equation depicting reaction between sodium phosphate and aluminum carbonate is as follows.

As this equation contains same number of atoms on both reactant and product side. So, this equation is a balanced equation.
According to the equation, 2 moles of sodium phosphate is giving 3 moles of sodium carbonate.
Therefore, sodium carbonate formed by 5.3 moles of sodium phosphate is as follows.

As number of moles is the mass of substance divided by its molar mass. So, mass of sodium carbonate ( molar mass = 105.98 g/mol) is as follows.

Thus, we can conclude that there is 842.54 grams of sodium carbonate are produced when 5.3 moles of sodium phosphate reacts with aluminum carbonate.
Answer:

Explanation:
Hello,
In this case, we apply the Boyle's law as an inversely proportional relationship allowing us to understand the pressure-volume behavior as shown below:

In such a way, solving for the final volume V2, we obtain:

Best regards.
Answer:
Some of the product is a gas that goes to the atmosphere.
Explanation:
Based on the chemical reaction of baking soda (Sodium bicarbonate: NaHCO₃) with vinegar (Acetic acid: CH₃COOH):
NaHCO₃(aq) + CH₃COOH(aq) → H₂O(aq) + CO₂(g) + CH₃COONa(aq)
When the reaction occurs, one of the products (CO₂) is a gas that will disappear of the mixture to stay in the atmosphere. That is the reason why there are missing 3 grams.
