Answer:
Explanation:
A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction.

Answer:
A) Test(independent) variable is bat wings.
B) Result (dependent) Variable is the Polyjuice Potion.
C) Cauldrons and fire
Explanation:
A) A test/independent variable is the variable that is being tested in the experiment or research and it is not affected by other variables in the experiment.
Now, in this experiment, what is being tested is are the bat wings.. Thus;
Test(independent) variable is bat wings.
B) Result (dependent) Variable is a variable that depends on the independent variable being tested. From the question, the result is the Polyjuice Potion.
Thus, Result (dependent) Variable is the Polyjuice Potion.
C) The constants are things that don't change with respect to any of the other variables. In this case, they are; cauldrons and fire
Answer:
increase the temperature
Explanation:
The solubility of a gas in a liquid will increase if: Lower the temperature of the solution , and therefore, lower the kinetic energy of the gaseous particles so they can escape the liquid phase less often.
Answer:
Explanation:
stoichiometry is used in cooking because it helps you determine the amount or proportion of compounds you will need in a chemical reaction. Stoichiometry is present in daily life, even in the cooking recipes we make at home. The reactions depend on the compounds involved and how much of each compound is needed to determine the product that will result.
In the average classroom. You have AC and DC energy that flows through the wires and powers your computers, phones, projector (if you have one), the light-bulbs in the ceiling or around the room. Their is potential energy when an object is at rest for example your pencil or desk, There is Kinetic energy when objects are moving for example if you walk around or something is rolling around. You yourself is an example of energy.<span />
