Answer:
THE NEW VOLUME OF THE GAS IS 406 mL WHEN THE TEMPERATURE CHANGES FROM 765 K TO 315 K.
Explanation:
When the temperature changes from 765 K to 315K, the volume has changed from 986 mL to?
V1 = 986 mL = 0.986 L
T1 = 765 K
T2 = 315 K
V2 = unknown
Using Charles' equation of gas laws;
V1 / T1 = V2 / T2
Making V2 the subject of the formula:
V2 = V1 T2 / T1
V2 = 0.986 * 315 / 765
V2 = 0.406 L
V2 = 406 mL
So therefore, the volume of a gas changes from 986 mL to 406 mL as a result of a change in temperature from 765 K to 315 K.
Answer:
Water's pH level is usually 6.5-8.5, any lower and it becomes acidic. Strong acid usually has a pH level of 0-1.

To determine the number of atoms of a substance given its number of mols, multiply number of moles with the Avogadro's number which is approximately equal to 6.022x10^23.
To answer the problem above, multiply 3.50 mols with <span>6.022x10^23. This gives a product of 2.1077x10^24.
Thus, there are </span><span>2.1077x10^24 atoms of sulfur in 3.50 mols of sulfur. </span>
