Answer: 24 gram is a final Answer.
Explanation:1 mol of carbon weight is 12 gram then
12.044×1023 contain 2 mole carbon so
Less than that of nitrogen and oxygen remember cnof "see noff" . this is the order of electronegativity carbon is less than nitrogen which is less than oxygen which is less than fluorine.
Answer:
Explanation:
2Al(s) + 3 I₂(s) → 2 Al⁺³ + 6 I⁻
Aluminium is oxidised and iodine is reduced .
so cell potential = Ereduction - Eoxidation
Al⁺³ + 3e = Al - 1.66 V
I₂ + 2 e = 2 I⁻ 0.54 V
= .54 - ( - 1.66 )
= 1.66 + .54
= 2.2 V
Geologist invented the geologic time scale to keep track of older rocks that have been layered over by newer rocks due to sedimentation that comes from other areas.

Answer:
the diaphragm and rib muscles contract
Explanation:
Inhalation is the set of movements that allows air to enter the lungs. In this process occurs the contraction of the diaphragm, causing its lowering. The intercostal muscles also contract causing the ribs to lift. This causes the chest to grow larger and the internal pressure of the lungs to become smaller than the external. With the reduction of intrapulmonary pressure, air ends up entering the airways and reaching the alveoli for gas exchange to occur.
