<h2>Let us solve for it </h2>

Explanation:

Magnesium oxide

It is MgO
Its molecular mass is : 24 +16=40 g
When MgO decomposes it forms = 3.54 g of oxygen gas
when 40 g of MgO decomposes it forms = 16g of oxygen
or we can say that :
16g of oxygen is produced when 40 g of MgO is decomposed .
1g of oxygen will be formed from =40/16g of MgO
3.54 g of oxygen will be formed = 40/16 x 3.54 =8.85g of MgO

Chloroform is a liquid once used for anesthetic. What is the volume of 5.0 g of chloroform? The density of chloroform 1.49 g/mL

mario62 [17]

Answer:

3.3557047 mL

Explanation:

The density can be found using the following formula:

$d=\frac{m}{v}$

Let's rearrange the formula to find the volume, $v$ .

$d*v=\frac{m}{v}*v$

$d*v=m$

$\frac{d*v}{d} =\frac{m}{d}$

$v=\frac{m}{d}$

The volume can be found by dividing the mass by the density. The mass of the chloroform is 5 grams and the density is 1.49 grams per milliliter. Therefore,

$m= 5g \\d= 1.49 g/mL$

Substitute the values into the formula.

$v=\frac{5g}{1.49 g/mL}$

Divide. When we divide, the grams, or g, in the numerator and denominator will cancel out.

$v= \frac{5}{1.49}mL$

$v=3.3557047 mL$

The volume of 5 grams of chloroform is 3.3557047 milliliters

What are valence electrons and why are they so important in chemistry?

stealth61 [152]

valance electrons that reside in the outermost shell of an atom in the highest energy level. They are important to atoms because the fewer valence electrons that the atom holds, it becomes less stable.

I take honors chemistry I hope this helps.
