Answer: 24 N
Explanation: solution attached:
F = ma
= 6.0 kg ( 4.0 m/s²)
= 24 N
Your answer is choice C. That is solid sodium chloride never dissolves to form sodium ions and chloride ions.
Going further to explain, have a look at the question again, we are told that James Proton prepares a saturated solution of sodium chloride in a beaker by adding solid sodium chloride and stirring.
Then when James finishes, crystals of sodium chloride are observed at the bottom of the beaker.
This implies that no more salt was dissolving since the saturation point was reached.
Again suppose he increased the temperature of the reaction, more salts could have dissolved.
1. the area would be 36
2. you would have to count trough each number until you have fully counted trough each dot example if there was a dot on -3 -2 trough 3 -2 you would have to count all the numbers untill you get trough -3 -2 to 3 -2
