Answer:
If the pressure of the system increases then the boiling point will increase.
If the pressure of the system decreases then the boiling point will decrease. If there is no change in pressure then the boiling point will remain constant.

Explanation:
Kory goes outside to grill some hamburgers. He tells Ethan that when you cook meat, a chemical reation is taking place. Ethan says "That's perpostrous!" Is Kory Correct??
absolutely Kory is correct
evidence of a chemical reaction are
new odor and or taste
change in color
signs of bubbling
direct effect of temperature on rate of change
evidence of a new substance being formed
we observe all these when we grill meat.
Answer :
(1) is act as a base and act as an acid.
(2) We can not classified as a base or an acid.
Explanation :
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydronium ions in water.
(1) The given chemical reaction is:
In this reaction, produces ions and produces ions.
Thus, is act as a base and act as an acid.
(2) The given chemical reaction is:
Arrhenius concept is only applicable on aqueous solution. Thus, we can not classified as a base or an acid.
Calculate the pOH first :
pOH =14-8.57=5.43
(OH)=10^-5.47
(OH)=3.72 x 10^-6 mol/L
Answer:
A. the temperature at which the motion of particles theoretically ceases.
Explanation:
Absolute zero is the same as 0 K (or zero Kelvin). At this point, the temperature cannot get any lower, and it is incredible difficult to get something to this low low temperature. The particles theoretically stop moving at 0 Kelvin aka absolute zero.
