Answer:
The particles that make up a substance in its liquid state have <u>more </u>kinetic energy than those of the same substance in its solid-state.
For a solid to melt, energy must be <u>added to</u> the system.
For a liquid to freeze, energy must be <u>removed from</u> the system.
The balanced chemical reaction is:
AgNO3 + NaCl = AgCl + NaNO3
We are given the amount of silver nitrate to be used for the reaction. This will be the starting point of our calculations.
15.0 mol AgNO3 ( 1 mol AgCl / 1 mol AgNO3 ) = 15.0 mol AgCl
This sentence is an example of double negative.
won't and never are two negative words, used in one sentence describing 1 thing.
Answer:
The answer is the level of egg above water.
Explanation:
The dependent variable is the variable that depends on something else to change.
The independent variable is the variable that changes. It also makes the dependent variable change.
The controlled variable is the variable that stays the same throughout the experiment.
For example, the independent variable in this experiment is the amount of salt that is added. The dependent variable is how the egg floats, or, in other words, the level of egg above water. The controlled variable is the amount of water in each cup.
Answer:
Electrical power is the product of voltage times current.
