The answer is: C. decomposition.

Decomposition is reaction where one substance is broken down into two or more simpler substances.

Balanced chemical reaction of water decomposition: 2H₂O → 2H₂ + O₂.

This is decomposition reaction, because from one molecule (water) two molecules (hydrogen and oxygen) are produced.

Chemical decomposition is opposite of chemical synthesis.

If 0.380 mol of barium nitrate is allowed to react with an excess of phosphoric acid, how many moles of barium phosphate could b

Vladimir [108]

If 0.380 mol of barium nitrate is allowed to react with an excess of phosphoric acid, 0.127 moles of barium phosphate could be formed.

<h3>How to calculate number of moles?</h3>

The number of moles of a compound can be calculated stoichiometrically as follows:

Based on this question, the following chemical equation is given:

Ba (NO3)2+ H3PO4 → Ba3(PO4)2+ HNO3

The balanced equation is as follows:

3Ba(NO3)2 + 2H3PO4 → Ba3(PO4)2 + 6HNO3

3 moles of barium nitrate produces 1 mole of barium phosphate

Therefore, 0.380 moles of barium nitrate will produce 0.380/3 = 0.127moles of barium phosphate.

6) Given that the density of olive oil is 0.92 g/mL, calculate the followin a. The mass of 20.0 mL of olive oil. The volume of 2

fgiga [73]

We are given:

Density of Olive oil = 0.92 g / mL

Mass of 20 mL Olive oil:

We know that the density = 0.92 grams / mL

multiplying the numerator and the denominator by 20

Density = 0.92 * 20 grams / 20 mL

Density = 18.4 grams / 20 mL

So, we have 18.5 grams in 20 mL of Olive oil

Volume of 20 grams Olive oil:

We need to multiply the numerator and the denominator of density by a number, that when multiplied by 0.92 will give 20

let that number be x:

0.92 * x = 20

x = 20/0.92

x = 21.74 (approx)

Multiplying the numerator and the denominator by x:

Density = 0.92 grams / 1 mL

Density = 0.092 * 21.74 / 21.74 mL

Density = 20 grams / 21.74 mL

So, we can see that 20 grams of the oil will have the volume 21.74 mL
