stiks02 [169]3 years ago
3 0

Answer:

The matter has changed size, shape, or form.

Explanation:

A new substance that is formed is creation.

if the matter changed from one substance to another this is called a chemical reaction.

Surely not. It won't change the molecular level.

Hope that helps.

5. Balance the equation and state the limiting reagent in the following reaction:
mr Goodwill [35]

Answer:

5. 2 Al  3 Cl2 and 2 AlCl3

Cl2 is limiting

(It has the highest coefficients, but that's not always true. If they give you the number of grams for each make sure to work the math out)

6. C

(As the pressure increases there is less volume for the molecules to move around, therefore the molecules will be closer together, allowing for more collisions.)

7.  b

(if the temperature is increases so will the rate of the reaction. The increase in temperature will allow for the molecules to move at a faster rate, allowing for more collisions (reactions) between them.

8. d

(dynamic equilibrium is the state at which the reaction is consistently moving, there fore the amounts should remain the same)

9. A

(a catalyst will lower the the pathway of activation energy because it's meant to speed up a reaction)

What are some problems and solutions to sending a human to jupiter
Ray Of Light [21]
The problem with sending a human to jupiter would be the fact that Jupiter has a thing called the red spot which has alot of gravity. The rest of space does not have gravity so there is a natural pull.

AlekseyPX

An increase in pressure increasing the billing point is an example of a physical property.

  • The term "boiling point" describes the temperature at which a liquid, which is being boiled, changes from a liquid to a vapor when its pressure equals that of its environment.
  • Physical changes are those that take place when a material's structure is the same both before and after the change.
  • When a substance is changed into another chemical substance, this is known as chemical transformation.
  • When describing the state of a physical system, a substance's physical qualities are those that can be measured.
  • A substance's characteristic that is seen in a chemical reaction is referred to as a chemical property.

As it demonstrates the physical state, the increase in pressure with boiling point is an example of a physical property.
