A form of energy associated with the positive and motion of the object.
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.
Answer:
So, 10 mole of water will weigh (18x10) = 180g.
You need to look at the electronegativity and decide wheter the difference of both of the numbers are significant enough to form a polar bond
Answer:
D. C + 2H₂ + ¹/₂O₂ → CH₃OH
Explanation:
The standard enthalpy of formation -ΔHf- is defined as the enthalpy change for the formation of 1 mol of a compound from its component elements.
Component elements are any element in its standard state.
For CH₃OH(l) at 25°C and 1 atm of pressure, the component elements are C(s), H₂(g) and O₂(g)
Thus, the equation that represent the standard enthalpy of formation of CH₃OH(l) is:
D. C + 2H₂ + ¹/₂O₂ → CH₃OH
