If 10g of sodium react with an unlimited amount of chlorine how much sodium chloride will get produced?

puteri [66]

Answer: Amount of sodium chloride produced is 25.43 grams.

Explanation:

To calculate the moles:

$\text{Number of moles}=\frac{\text{Given mass}}{\textMolar mass}}$

Given: Mass of sodium = 10 g

Molar mass of sodium = 23g/mol

$\text{Moles of sodium}=\frac{10g}{23g/mol}=0.4347mol$

The balanced equation is:

$2Na+Cl_2\rightarrow 2NaCl$

By Stoichiometry of the reaction,

2 moles of sodium produces 2 moles of sodium chloride

So, 0.4347 moles of sodium will produce = $\frac{2}{2}\times 0.4347=0.4347mol$ of sodium chloride.

Molar mass of sodium chloride = 58.5 g/mol

Putting values in equation 1, we get:

$0.4347mol=\frac{\text{Mass of NaCl}}{58.5g/mol}=25.43g$

Hence, amount of sodium chloride produced is 25.43 grams.

What kind of reaction happens when you mix Baking soda and vinegar? (In your own words)

Leno4ka [110]

An acid base reaction occurs since we know that vinagar is just acetic acid and baking soda is just sodium bicarbonate. The vinagar (weak acid) is going to react with the bicarbonate (weak base) to create carbonic acid which decomposes into carbon dioxide and water. I hope this helps. Let me know in the comments if anything is unclear.
