It is A. This is because the rate of reaction is defined as the speed at which the reactants are converted into the products.
Answer:
Electrons have an electric charge of -1.60 × 10-19 C
Explanation:
Neutrinos and Neutrons have 0 e charge.
Protons have an electric charge of 1.60 × 10-19 C
Historically, electrons were assigned a negative charge
Molar mass SiO2 = 28 + 32 = 60
<span>so moles sand = 3.4 x 10-7 / 60</span>
The purpose is that it shows you all the elements we know and it arranges them in groups that are also the same kind like Chemistry.
