Answer:
14 moles of oxygen needed to produce 12 moles of H2O.
Explanation:
We are given that balance eqaution
We have to find number of moles of O2 needed to produce 12 moles of H2O.
From given equation
We can see that
6 moles of H2O produced by Oxygen =7 moles
1 mole of H2O produced by Oxygen=moles
12 moles of H2O produced by Oxygen=moles
12 moles of H2O produced by Oxygen=moles
12 moles of H2O produced by Oxygen=14 moles
Hence, 14 moles of oxygen needed to produce 12 moles of H2O.
Given mass of Scandium = 50.0 g
Increase in temperature of the metal when heated =
Heat absorbed by Scandium =
The equation showing the relationship between heat, mass, specific heat and temperature change:
Where Q is heat =
m is mass = 50.0 g
ΔT =
On plugging in the values and solving for C(specific heat) we get,
=50.0g(C)(
)
C = 0.491
Specific heat of the metal = 0.491
