Answer:
A. it is the lowest at low temperatures
Explanation:
At low temperature the kinetic energy of a molecule is low. The kinetic energy is directly proportional to the temperature of the molecule. The kinetic energy of a molecule increases with the increase in the temperature that energize the molecules of a substance and makes them to move faster than before.
As the kinetic energy is proportional to temperature so it does not increase with decrease in the temperature (low temperature). The kinetic energy varies with the change in the temperature and it is not same at all temperature. The kinetic energy is highest at high temperature. Thus, option A is correct.
2 is your answer hope you get it right
Answer:
A
Explanation:
It shines bright just like the sun hopes this helps
Hey there!:
Given the reaction:
NaBr ⇌ Na⁺ + Br⁻
↓ ↓ ↓
0.150M 0.150M 0.150M
AgBr ⇌ Ag⁺ + Br⁻
↓ ↓ ↓
x x 0.150M
Therefore:
Ksp = x * 0.150
x = ( 7.7 * 10⁻¹³ ) / 0.150
x = 5.1 * 10⁻¹²
Answer B
Hope that helps!
Answer:
The number 10,847,100 in Scientific Notation is 
Explanation:
Scientific notation is an easy form to write long numbers and it is commonly used in the scientific field. To write a long number in a shorter way it is necessary to 'move' the decimal point to the left the number of positions that are necessary until you get a unit. Then you write the number and multiplied it by 10 raised to the number of positions you moved the decimal point. In this case, it is necessary to move the decimal point 7 positions so, we multiply the number by 10 raised to 7.
