Answer:
CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).
So first finding the mass of 1 molecule of CO2 which is equals to
= mass of 1 carbon atom + masses of 2 oxygen atom, we get
= 12+(16*2)= 12+32= 44 a.m.u.
Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )
1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams
So our answer is 110 grams
We have: A= F.s
So, A = 22 x 16
A= 352J
Só A is correct answer
Since Jason plays a lot of sports <em>(D)</em>, there's a good chance that he has developed a greater-than-average lung capacity. This is a good thing.
Answer: young's modulus
Explanation: A very rigid material—one that stretches or compresses only slightly under large forces—has a large value of young's modulus .
Variables shift both the long-run and short-run aggregate-supply curves are productivity, labor Wage Costs and taxes and other costs.
<h3>What is aggregate-supply?</h3>
The entire quantity of goods and services that enterprises in a national economy intend to sell during a certain time period is known as aggregate supply
Variables shift both the long-run and short-run aggregate-supply curves are ;
1. Productivity
2. Labor Wage Costs.
3. Taxes and other costs -
4. Material Prices.
5. Size of labor force.
6. Stock of Capital.
Hence, variables shift both the long-run and short-run aggregate-supply curves are productivity, labor Wage Costs and taxes and other costs.
