Answer:
151.63 g
Explanation:
We first get the number of moles;
Moles = Molarity × volume
= 2.0 × 0.475
= 0.95 moles
1 mole of CuSO4 = 159.609 g/mol
Therefore;
Mass = moles × molar mas
= 0.95 moles × 159.609 g/mol
= 151.63 g
Answer:
A) The law of conservation of energy states that energy can neither be created nor destroyed.
and
B) Energy can be transferred from one object to another, and it can assume different forms.
The correct option would be the fact that both bonding electrons had come from the oxygen to form this chemical bond.
The other options are not true.
Answer:What are the two half reactions that show how many electrons are gained or lost by each species in the reaction:
Ni2+(aq) + Mg(s) → Ni(s) + Mg2+(aq)?
atoms cannot be created or destroyed in a chemical reaction
