Answer:
0.1
tenth
hundredth (0.01)
1.05 (can be anywhere from 1.00 to 1.10)
11.42 (can be anywhere from 11.40 to 11.50)
yes, it falls within reasonable doubt
Rate of Reaction ca be increased by applying following changes,
1) Increase in Temperature:
Increase in Temperature results in the increase of Kinetic Energy, Hence, velocity of reactants increases and rate of collisions increases. Thus, more reactants colloid with enough energy to change into products in given time.
2) Decrease in Activation Energy:
Activation energy is the minimum amount of energy required by reactants to cross the energy barrier to convert into products. Hence, activation energy is decreased by using catalyst.
3) Concentration of Reactants:
The greater the concentration of reactants, greater is the number of reactants per volume. More reactants in less area increase the probability of collision. Hence, collisions increase and rate of reaction increases.
4) Increasing Surface Area of Reactant:
Greater the surface area greater is the rate of reaction.
The answer is heterogeneous mixture.

Answer: The "Forchhammer" principle
I hope that this helps you !
Answer:
It works by separating the fuel from the oxygen. The oxygen comes from the air. It is the same oxygen we breathe. Since the oxygen has to be in contact with the fuel, if you can coat the fuel with something that keeps the oxygen away, the fire will go out which is what the fire extinguisher does.
