sodium ions in 2.11 mol of sodium carbonate.
The sodium carbonate, the inorganic substance with the formula, is also known as washing soda, soda ash, and soda crystals.
All of the forms are water-soluble, odourless, white salts that produce slightly alkaline solutions in water. In the past, it was recovered from the ashes of plants that were raised in soils high in salt.
The term "soda ash" originated to refer to sodium carbonate because the ashes of these sodium-rich plants were probably distinct from the wood ashes that were originally used to make potash. The Solvay technique is used to produce it in large amounts from limestone and sodium chloride.

Answer:
15.2 grams of calcium chloride are produced and HCl is the limiting reactant.
Explanation:
Hello there!
In this case, according to the described scenario, it is possible to realize that the reaction between hydrochloric acid and calcium hydroxide is:
Whereas there is a 2:1 mole ratio of the acid to the base. In such a way, with the given masses, we can compute how much calcium chloride product is produced due to the chemical reaction via stoichiometry:
Whereas we infer that the correct amount is 15.2 g since HCl is the limiting reactant as it produces the fewest grams of the desired product. Consequently, the calcium hydroxide is the excess reactant here.
Regards!
Answer:
<h2>111.11 mL</h2>Explanation:
Since the moles of gas and temperature are held constant the new volume can be found by using the formula for Boyle's law
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question
P1 = 1 atm
P2 = 2.25 atm
V1 = 250 mL
We have
We have the final answer as
<h3>111.11 mL</h3>Hope this helps you
