Answer:
see below
Explanation:
1. combustion
2. The breakdown of hydrogen bromide is endothermic, and the formation of hydrogen iodide is exothermic.
3. the water
4. H–H
5. It is endothermic because more energy is needed to break up the reactants versus the amount given off by the products.
6. NO
7. H–F
8. sunlight warming a concrete sidewalk
9. The total energy of the system will stay the same as kinetic energy from the warm water increases the kinetic energy of molecules in the ice
10. This is an exothermic reaction because the reactants have more energy than the products.
11. the energy that must be added to a system to break the bonds of the reactants
12. The activation energy required for manganese dioxide to form intermediate molecules with H2O2 is less than the activation energy required for H2O2 to decompose on its own.
13. written response
14. written response
15. written response
16. written response

Answer:
They are both celestial bodies orbiting our Sun, and they both can have unusual orbits, sometimes straying close to Earth or the other planets.
If the moon is on the other side of the earth, the water is getting pulled back because of the gravity force but if the moon is on the same side of the beach it's high tide.
By putting it in water because all the pease will fall to the bottom
<h3><u>Answer;</u></h3>
New information changed the understanding of the atom’s structure.
<h3><u>Explanation;</u></h3>
- <em><u>Mendeleev is know as the Father of the Modern Periodic Table. His table allowed scientists to predict the existence of elements that hadn't been discovered.</u></em>
- Mendeleev saw that when the elements were arranged in order of increasing atomic mass, those that had similar properties occurred in a repeating pattern. He predicted that elements yet to be found would fill the gaps in his table.
