A
answer=
D. average kinetic energies
6
Q

A
answer=
homogeneous
11
Q
- how many grams of sodium chlorate or needed to make a saturated solution and 100 g of water at 90°C
A
answer=
180 g
12
Q
- in terms of saturation how would you classify potassium bromide solution with a concentration of 90 g and 100 g of water at 10°C
A
answer=
Super saturated
13
Q
- in terms of saturation how would you classify a potassium nitrate solution of 30 g in 100 g of water at 40°C
A
answer=
unsaturated
14
Q
- what is the solubility of which salt is the least affected by temperature
A
answer=
Salt/sodium chloride
15
Q
- I am in action react to form with us. What what happened to the mass of the razz compared to the mass of the yard and auction before the reaction? Explain why this occur
A
answer=
same because the law of conservation of mass says matter cannot be created or destroyed even in a chemical change
