This is a reaction of combustion of methane
CH₄ + 2O₂ = CO₂ + 2H₂O
k(H₂O)=2
ZnO + C → Zn + CO
I don't know what oxidised an reduced means
A molecule of a compound is composed of at least two types of atoms.
Explanation:
A molecule is defined as when two or more atoms of an element combine together by the bonds by sharing the electrons as O^2 (oxygen molecule)
A compound is a molecule when two different types of atom joined by chemical bonds as covalent, ionic or coordinate bonds as NH^3 ( ammonia)
Answer:
The answer is
<h2>11.33 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of metal = 34 g
volume of metal = final volume of water - initial volume of water
volume = 25.3 - 22.3 = 3.0 mL
The density is
We have the final answer as
<h3>11.33 g/mL</h3>
