A piece of toast came out of the toaster very overcooked.
Nikitich [7]

Answer:

It is a chemical change ⇒ 1st answer

Step-by-step explanation:

* Lets explain the statements to solve the problem

- <u><em>A chemical change</em></u> occurs when a new substance is formed through

 a chemical reaction

- Ex: cooking an egg

- <u><em>Change of reaction</em></u> is the rate of reaction it can be decreases or

  increasing

- <u><em>A phase change</em></u> is a change from one state to another without a

 change in chemical composition

- Ex: Condensation: the substance changes from a gas to a liquid

- <u><em>A physical change</em></u>, such as a state change or dissolving, but does

 not create a new substance

- Ex: Breaking a glass

* Lets solve the problem

- A piece of toast came out of the toaster very overcooked.

∵ It is like the cooking an egg

∴ It is a chemical change

Solve for g<br> 2h - 49 = 12
frez [133]

Answer: h = 30.5

Step-by-step explanation

2h - 49 = 12

     +49 +49

Add 49 to both sides. Inverse operation

2h = 61

2h/2 = 61/2

Divide 2 to both sides to get answer. Inverse operation

h = 30.5

Check:

2(30.5) - 49 = 12

       61 - 49 = 12

               12 = 12
