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
Answer:
5/12 or 15/36
Step-by-step explanation:
Since he rolls two dice, he has a total probability of 6 times 6 = 36. The pairs, that he could add up to primes are (1,1), (2,1) * 2 (since he can get 1,2 as well), (1,4) * 2, (2,3) * 2, (3,4) * 2, (5, 2) * 2, (6,1) * 2, (5, 6) * 2. This is 1 + 2 + 2 + 2 + 2 + 2 + 2 + 2, which is equal to 15. This is a total of 15/36 possible ways, which is also equal to 5/12.
No it does not equal 4 fifths
Answer:
87km
Step-by-step explanation:
Volume is proportional to radius cubed, so radius is proportional to the cube root of volume.
Increase volume by a factor of 10^6 and radius increases by a factor of the cube root of 10^6, which is 10^(6/3) = 10^2 = 100.
100 * 0.87 km = 87 km
You should aske them together in 1 quesiton (I am assuming the scale had 5 pounds before)
so 5-2=3 pounds
to ounces=3 times 16 since 16 oz pper ppound
3 times 16=48 oz
