<span>The molar mass of the compound is 122 g. </span>
Answer:
13. c) Net
14. a) Gravity
15. d) Watt
16. b) the speed will suddenly decrease.
Explanation:
13. The <u>net </u> force is combination of all individual forces.
14. When we sit on the chair , then <u>gravitational force</u> acts on our body due to our mass.
F = mg
here, F = force due to gravity , g = acceleration due to gravity and m= mass of the body
15.Power : It is the force acting per unit area .It is discovered by James Watt

Its unit is
.In honor of the Scientist , its unit is Watt.
Watt = 
16. When the parachute first opens , the <u>speed of the skydiver suddenly decreases</u> because of the resistance offered by the air particles.(For more details look at the figure attached)
17. Transfer of momentum from one object to other is t<u>he law of conservation of momentum</u><u> </u>(NOT ENERGY).So the answer is<u> </u><u>False</u>
<u> Law of Conservation of Momentum : </u> Total momentum of a system is conserved if no external force attack on it. Momentum can neither be created nor destroyed but transferred from one form to other.
One thing incorrect is that when dealing with a compound, such as H2SO4, that has 7 atoms in the chemical formula, the polyatomic ion SO4 doesn’t dissociate into one Sulfur and four Oxygens. SO4 stays and a PAI.
Answer:
13.0mL
Explanation:
So this is a classic M1V1=M2V2 problem, where M is molarity and V is volume and the subsequent numbers represent the two sets of condition (1 being before dilution and 2 being after dilution)
So M1 is going to be 5.0M because it is our initial molarity and V1 is what we are trying to find since we are trying to find how much of initial volume should be diluted.
M2 is 1.30M since it is what molarity is after dilution and M2 is what volume is after dilution which is 50mL.
So M1V1=M2V2 (becomes an algebra problem)
5*V1=1.30*50
V1= 13.0mL
Now this answer should make sense since to dilute something with large molarity to small you only need very few mL than the final volume because you add water to dilute it.
Sweating is your body releasing water to cool it’s self down. When doing an activity the water in ur body warms up. And is then released to stop from overheating
