Is 2 C4H10 + 13 O2 → 8 CO2 + 10 H2O a double replacement?
natulia [17]

Answer:

The answer to your question is No, it is not.

Explanation:

Data

                C₄H₁₀  +  13O₂   ⇒   8CO₂ +  10H₂O

In a double replacement reaction, two reactants interchange cations an example of these reactions are neutralization reactions. In neutralization reactions, an acid and a base react to form a salt and water.

The reaction of this problem is not a double replacement reaction because the products are carbon dioxide and water, not a salt and water.

The reaction of this problem is a combustion reaction.

a chemist measures 20.00 moles of water H2O . How many grams of water is that? PLS HELP WILL GIVE BRAINLIST
DedPeter [7]

Answer:

360.4 grams

Explanation:

The first step is to find the molecular mass of H2O. The molecular mass of a molecule is the atomic masses added altogether. Because there are 2 hydrogens, we need 2x the atomic mass. 2(1.01) + 1(16.00) = 18.02 amu.

The molar mass of H2O is 18.02 g/mol. This is the unit converter to change from moles to grams

20.00 mol H2O *\frac{18.02 g H2O}{1 mol H2O} =360.4 g
