Answer:
The mass of formed sodium sulphate solution is 14.2 g.
Explanation:
From the given,
Mass of copper sulphate = 15.9 g
Mass of sodium sulphide = 7.8 g
Total mass of reactant = Mass of copper sulphate + Mass of sodium sulphide
= 15.9 + 7.8g = 23.7g
Mass of copper sulphide formed = 9.5 g
Mass of sodium sulphate = Total mass - Mass of copper sulphide
= 23.7 g - 9.5 g = 14.2 g
Therefore, The mass of formed sodium sulphate solution is 14.2 g.
Answer:
True
Explanation:
Competition is the act of competing with one another for a particular resource. An example is two animals quarrelling over a food or two people quarreling over who lost their money. Competing is a type of rivalry in which two people compete for one resource. The answer for this question is True.
Answer: Value of impulse is
