Which statement is the best description of the energy found in molecules of water?
A. Colder molecules have more kinetic energy.
B. Hotter molecules have more kinetic energy
C. A molecule’s temperature is not connected to its energy
D. Colder molecules have more thermal energy
1. Cs-Br
2. Fr–Cl = 2.46
3.Hotter molecules have more kinetic energy.
4.The reaction is exothermic.
5. More bond energy is absorbed on the reactants side than is released on the products side.
6. an exothermic reaction
7. Endothermic reactions have a higher activation energy. Endothermic reactions require more energy to break up the bonds of the reactants.
8. Heat must be released by the products in order to convert from the reactants.
9. Cooling a purple solution will turn it pink.
10. Both are flexible, but one conducts electricity while the other insulates.
11. high pressure, high temperature water extraction
12. reducing environmental impact
13. 15
14. The number of atoms, type of elements, and mass of reactants and products are equal.
15. 64 grams
16. 1.503×1023
17. The relative numbers of protons and neutrons can differ before and after the change, but the total number of those particles remains the same.
18. Fission is a process in which a large nucleus is split into smaller nuclei.
19. beta-minus decay
20. alpha decay
21. Greenhouse gases have more than two atoms, allowing them to vibrate and release radiation, warming the atmosphere.
22. cause: acid rain
consequence: destruction of crops
23. toxic bacteria in the water supply
24. It reaches hard to get to oil and gas deposits.
got a 100 this was so helpful
yessir
Thank you so much!!
16 and 20 are not right.
16 is the other option and 20 is Beta Decay (if it says a proton is added to the product it is beta decay).
