Answer:
The mass of cryolite will be produced = 71247 g or, 71.247 kg
Explanation:
The balanced chemical equation for the synthesis of cryolite
Al₂O₃(s) + 6 NaOH(l) + 12 HF(g) → 2 Na₃AlF₆ + 9 H₂O(g)

Answer:</h3>
Sodium
<h3>
Explanation:</h3>
- To answer the question we need to know a few things.
What are cations?
- Cations are positively charged ions that are formed when an atom of an element loses an electron(s).
What elements form cations?
- Metallic elements form cations since they react by losing electrons thus forming ions with a positive charge.
- For example, alkali metals such as sodium form cations with a charge of +1.
- In this case, sodium will form a cation with a charge of + 1, Na⁺
What are negatively charged ions?
- Negatively charged ions are known as anions.
- They are formed by non-metallic elements such as sulfur, argon, silicon, etc.

Answer:
38.8 mL
Explanation:
2CO(g) + O₂(g)⟶2CO₂(g)
Because pressure and temperature remain constant, we can <em>think of the moles ratios as volume ratios</em>. This means that 2mL of CO react with 1 mL of O₂ to produce 2 mL of CO₂.
Because the problem asks us to calculate the amount of oxygen gas unreacted, then CO is the limiting reactant. We <u>calculate the amount of O₂ that reacted</u>, from the available amount of CO:
82.4 mL CO *
= 41.2 mL O₂
Thus, the oxygen gas remaining is:
80.0 mL - 41.2 mL = 38.8 mL O₂
