Change in the amount of volume left inside the basketball for the remaining air coming in
Answer:
Work = 450 J
Explanation:
Force = 90N
Distance = 5m
Work = ?
The relationship between these quantities is given by the equation:
Work = Force * Distance
Work = 90 * 5
Work = 450 J
From the balanced equation, we can see that 1 mole of CH4
releases 802.3 kJ of heat upon combustion. The mass of 1 mole of CH4 is:
mass CH4 = 16.04 grams
So by ratio and proportion:
mass required = (-268 kJ) / (-802.3 kJ / 16.04 grams)
<span>mass required = 0.334 grams</span>
Answer:
N2 + 3H2 ------> 2NH3
2AlBr + 3K2SO4------> 6KBr + Al(SO4)3
