When it gains an electrons is negatively charged so in this case I think it will be. -ion
Answer:
0.3382 kg
Explanation:
From the illustration:
<em>100g of the ore would contain 20.7 g of nickel by mass</em>. In order to obtain 70.0 g of nickel, the amount of the ore needed would be:
100 x 70.0/20.7 = 338.16 g
According to conversion units:
<em>1 g = 0.001 kg</em>
Hence,
338.16 g = 338.16 x 0.001 = 0.3382 kg
<em>Therefore, </em><em>0.3382 kg</em><em> of the ore would be required in order to obtain 70.0 g of nickel.</em>
Answer:
B. Anions are formed when an atom loses electrons.
Molar volume is a property of a component in a solution. It is defined as the volume occupied by one mole of the component in the closed system. You would not expect all solutions to execute volume additivity because intermolecular forces between the components come into play. There is no such thing as conservation of volume.
Vapor pressure affects molar volume because gases are very sensitive by these process conditions. Vapor pressure is very temperature-dependent. Consequently, at a different temperature, your component could expand or compress, thus, affecting the molar volume. Moreover, the pressure affects the molecular collisions in the system.
