The answer for the following problem is mentioned below.

Therefore; if 2.5g of magnesium is reacted then 4.16 grams of magnesium oxide is reacted.

Explanation:

Given:

mass of magnesium = 2.5 grams

We know;

molar mass of magnesium (Mg) = 24 grams

molar mass of magnesium oxide (MgO) =24 +16 = 40 grams

2Mg + O2 → 2MgO

2×24 2×40

If;

2×24 grams of Mg → 2×40 grams of MgO

Then;

2.5 grams of Mg → ?

= (2×40 × 2.5 ) ÷ 2×24

= 4.16 grams

Therefore; if 2.5g of magnesium is reacted then 4.16 grams of magnesium oxide is reacted.

So therefore 4.16 grams of magnesium oxide is made.

Answer:

1.4952 grams of sodium bicarbonate she would need to ingest to neutralize this much HCl.

Explanation:

$Moles (n)=Molarity(M)\times Volume (L)$

Moles of hydrochloric acid = n

Volume of hydrochloric acid solution = 200.0 mL = 0.200 L

Molarity of the hydrochloric acid = 0.089 M

$n=0.089 M\times 0.200 L=0.0178 mol$ of HCL

$HCl(aq)+NaHCO_3(aq)\rightarrow NaCl(aq)+H_2O(l)+CO_2(g)$

According to reaction, 1 mole of HCl is neutralized by 1 mole of sodium bicarbonate.

Then 0.0178 moles of HCl wil be neutralized by :

$\frac{1}{1}\times 0.0178 mol=0.0178 mol$ of sodium bicarbonate

Mass of 0.0178 moles of sodium bicarbonate:

0.0178 mol × 72 g/mol = 1.4952 g

1.4952 grams of sodium bicarbonate she would need to ingest to neutralize this much HCl.

3. If the percent by volume is 2.0% and the volume of solution is 250 mL, what is the volume of solute in solution? (1 point) 0.

igor_vitrenko [27]

Volume percent = Volume of solute
----------------------------------
Volume of the solution

   2 Volume of the solute
------- =   ------------------------------
100 250

Volume of the solute = 2 x 250
------------
100

= 5 mL.

Hope this helps!
