Writing Equations 1. Potassium reacts with fluorine
2. Potassium nitrate reacts with zinc phosphate
3. Iron (III) hydroxide reacts with phosphoric acid
4. Sodium reacts with nitric acid
5. Copper reacts with nickel (II) acetate
6. Manganese (II) chloride reacts with cesium chlorate
7. Propane (C3H8) combusts with Oxygen.

What is the answer to these 7 questions?

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

10 years is the answer

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
