Answer:
C
Explanation:
Temperature is directly related to kinetic energy (KE). As we raise temperature, we are raising KE, as well. Particles with more KE move more quickly and with more force.
This means that these particles are more likely to collide with each other and react to allow the chemical reaction to follow through. In turn, if the chemical reaction is more likely to go to completion, the reaction rate increases, eliminating A and B.
The concentration of the solute is not affected by the temperature; in other words, temperature will not increase or decrease the amount of solute in the solution, so eliminate D.
Thus the answer is C.
Hope this helps!
I’m pretty sure it’s in a group (column) of the period table. Hope this helps :)))
I would say the answer is emissions. These are the particles that are not supposed to be present in air but due to the production of different substances from humans daily activities these substances go with the air we breath. Hope this helped.
Answer:
One can of cola contain 0.16 kcal of carbohydrates.
Explanation:
Given data:
mass of cola can = 40 g
kilocalories of carbohydrates = ?
Solution:
we know that there are 4 cal of carbohydrates per gram.
40 g × 4 cal/g = 160 cal
Now we will convert calories into kilocalories. There are 1000 calories in one kilocalories so,
160/1000 = 0.16 kcal
so, one can of cola contain 0.16 kcal of carbohydrates.
