When many atoms share electrons together.
Answer:
Atoms of the reactant(s) must equal the atoms of the product(s).
Explanation:
According to the Law of Conservation, all atoms of the reactant(s) must equal the atoms of the product(s).
As a result, we need to balance chemical equations. We do this by adding in coefficients to the reactants and/or products. The compound(s) itself/themselves DOES NOT CHANGE.
Fe^2 O^3 + 6HCl --> 2FeCl^3 + 3H^2 O
Answer:
4 M
Explanation:
Molarity refers to the molar concentration of a substance (solution). It can be calculated by using the formula below:
Molarity (M) = number of moles (n) ÷ volume (V)
According to the information provided in this question;
V = 0.4 liter
n = 1.6 moles
Molarity = n/V
Molarity = 1.6/0.4
Molarity = 4 M
Answer:
Covalent bonds are found between atoms within hydrocarbon molecules.
