This corresponds to the law of multiple proportions which states that when a certain amount of compound reacts to form another compound, the ratio of the amounts between the reactants and the products are a fraction of simple or whole numbers.<span />
Answer:
5.66 %.
Explanation:
<em>mass percent is the ratio of the mass of the solute to the mass of the solution multiplied by 100.</em>
<em />
<em>mass % = (mass of solute/mass of solution) x 100.</em>
<em></em>
mass of potassium nitrite = 30.0 g,
mass of the solution = mass of water + mass of potassium nitrite = 500.0 g + 30.0 g = 530.0 g.
<em>∴ mass % = (mass of solute/mass of solution) x 100</em> = (30.0 g/530.0 g) x 100 = <em>5.66 %.</em>
D. A constant pressure calorimeter would be used because an increase in heat causes an increase in pressure.
Answer:
gamma decay.
Explanation:
A gamma decay emits only a gamma-ray photon,
