NiCl₂ commonly forms a green aqueous solution.
Its total charge is zero but for the elements:
Sn===> Sn4+ positive
Cl===> Cl- negative
Answer: heat required to raise the temperature
Explanation: Heat equation is represented as:

Q= heat required to raise the temperature
m= mass of the substance
c = heat capacity of substance

Answer:
59.2 grams
Explanation:
We are given that 70.4% of the weight of the total 200 g of the concentration is made up of nitric acid, the remaining information is not required to solve the problem. Since water and nitric acid are the only components of the solution, the total weight of water is given by:

There are 59.2 grams of water in this solution.
