Hey there!:
1 mole O2 ----------------- 22.4 L ( at STP )
( moles O2 ) -------------- 2.50 L
moles O2 = 2.50 * 1 / 22.4
moles O2 = 2.50 / 22.4
moles O2 = 1.12*10⁻¹
Answer B
Hope that helps!
Explanation:
5.76 is the answer
vinegar a day and the molarity of the vinegar is 0.84 M, then how m
Answer:
T₂ = 43.46 °C
Explanation:
Given that:
The heat of the formation of carbon dioxide = - 393.5 kJ/mol (Negative sign suggests heat loss)
It means that energy released when 1 mole of carbon undergoes combustion = 393.5 kJ = 393500 J
Heat gain by water = Heat lost by the reaction
Thus,
For water:
Mass of water = 5100 g
Specific heat of water = 4.18 J/g°C
T₁ = 25 °C
T₂ = ?
Q = 393500 J
So,
T₂ = 43.46 °C
