Answer:
Mass, temperature, and phase.
I think temperature because the higher the temperature of a given quantity of a substance, more is its thermal energy. Similarly, for the same temperature, higher mass of a substance will contain more thermal energy.

How does a material get a negative charge?
Answers
Explanation:
When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. The material that gains electrons becomes negatively charged. The material that loses electrons is left with a positive charge.

Lithium 1s22s1
Chlorine 1s22s22p6 3s23p5
A. 1:1
B. 1:2
C. 2:1
D. 3:1
D. 3:1
Answers
Answer:
A. 1:1
Explanation:
Lithium 1s2 2s1
Chlorine 1s2 2s2 2p6 3s2 3p5
Lithium is a group 1 element. When it forms a compound, it loses it's one valence (outermost) electron.
Chlorine is a group 7 element. When it forms a compound, it gains one electron to achieve a stable electronic configuration.
Since Li loses one electron and Cl gains one electron. The formular of the compound formed would be;
LiCl
The correct option is;
A. 1:1

Imagine disease kills 85 percent of the wolf population. How will it affect the other organisms?
Answers
Answer:
There would most likely be an overpopulation of the animals the wolfs ate.
Explanation:
Answer:
Many populations will grow way to much. Also others will drop in numbers drastically.
Explanation:
Due to the fact that wolves are predators, the prey they eat will grow 85% more. Now, 85% of the wolf population dies, that`s a lot of prey not eaten. Then the prey that are predators to other animals who are over hunted by their predators will most likely drop in numbers drastically, by I mean 85%. This will throw the ecosystem off so much, humans could be at grave risk.

b) Write a few paragraphs describing the chemical reaction and explaining the energy change in the reaction. Your document should: i. identify the reactants and products. ii. describe the change in energy that occurs as bonds are broken and formed. iii. identify how the potential energy of the reactants compares to the potential energy of the products. iv. state and explain the net change in enthalpy. v. identify whether the reaction is endothermic or exothermic. vi. explain how energy is conserved between the reaction and the surrounding environment.
Answers
Answer:
The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy.
Explanation:
if u want to u can give me the crown btw have a good day
Answer:
here is what i put for this project:
The reaction in this project is exothermic. The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy. The potential energy in reactants is higher than the potential energy of products in an exothermic reaction. Since energy is given off, the products are lower in energy than the reactants. The energy that is given off is a result of the formation of new bonds.
The change of the enthalpy happening in the chemical reaction is different from the pathway in between the initial and the final states. The addition of the equation gives the net change of the enthalpy. Enthalpy change is the amount of heat evolved or absorbed in the reaction under constant pressure. This can be calculated by checking the amount of heat evolved during the reaction. This reaction occurs at a constant pressure.
