Answer:

THE NEW VOLUME OF THE GAS IS 3.124 L

Explanation:

Initial Temperature = 27°C = 27 + 273 K = 300 K

Pressure = constant

Initial Volume = 3.3 L

Final Temperature = 11 °C = 11+ 273 K = 284 K

Final volume = unknown

Using Charles' law, at constant pressure, the volume of a given gas is directly proportional to the temperature.

Mathematically,

V1 / T1 = V2 / T2

Re-arranging the formula by making V2 the subject of the formula

V2 = V1 T2 / T1

V2 = 3.3 * 284 / 300

V2 = 3.124 L

The new volume of the gas is therefore 3.124 L at 11°C

Some forms of vitamin D, C₂₈H₄₄O, can be found in red meat. How many total atoms are in 5 molecules of C₂₈H₄₄O
MaRussiya [10]

Answer:

3.01 × 10^24 atoms of vitamin D

Explanation:

The number of atoms, molecules or ions present in a substance is given by the Avogadro's number which is 6.02 × 10^23.

Hence;

1 molecule of vitamin D contains 6.02 ×10^23 atoms

5 molecules of vitamin D contains 5 × 6.02 ×10^23/1

= 3.01 × 10^24 atoms of vitamin D

If 16 moles of al react with 3 moles of S8 how many moles of Al2 S3 will be formed
Gnom [1K]

Answer:

8 moles

Explanation:

Al reacts with S_8 to produce Al_2S_3 as

Al+S_8\rightarrow Al_2S_3

The balanced chemical equation is

16Al+3S_8\rightarrow 8Al_2S_3

In the reaction, 16 moles of Al react with 3 moles of S_8 to produce 8 moles of Al_2S_3.
