No because carbon is a gas and sand is a solid
Answer:
yes its correct, temperature is a measure of energy particles have, the more energy the faster they move and the higher the temp
Explanation:
100.3kcal of heat will be absorbed.
2moles of NO absorb 43kcal.
I mole of NO weighs 14 +16 = 30g so 2 moles weigh 60g.
So 60g absorb 43kcal
So 1g absorb 43/60 kcal
So 136g absorb (43/60) x 136 = 97.47 kcal
Answer : The correct option is, 0.21 moles
Solution : Given,
Molarity of the solution = 0.85 M = 0.85 mole/L
Volume of solution = 250 ml = 0.25 L 
Molarity : It is defined as the number of moles of solute present in one liter of the solution.
Formula used :
Now put all the given values in this formula, we get the moles of solute of the solution.
Therefore, the moles of solute is, 0.21 moles
