Answer:
C is the element thats has been oxidized.
Explanation:
MnO₄⁻ (aq) + H₂C₂O₄ (aq) → Mn²⁺ (aq) + CO₂(g)
This is a reaction where the manganese from the permanganate, it's reduced to Mn²⁺.
In the oxalic acid, this are the oxidation states:
H: +1
C: +3
O: -2
In the product side, in CO₂ the oxidation states are:
C: +4
O: -2
Carbon from the oxalate has increased the oxidation state, so it has been oxidized.
Answer: intermolecular forces are described as forces that either cause attraction or repulsion between neighbouring particles or molecules
Explanation: liquids with strong intermolecular forces has the following properties:
1.) High boiling point
2.) high surface tension
3.) Low viscosity
4.) Low vapour pressure
While liquids with weak intermolecular forces has the following properties:
1.) Low boiling point
2.)low surface tension
3.) High viscosity
4.) High vapour pressure.
Formal charge = valence electron - bonds - dots.
double bonded oxygen = 6-2-
4 so it is 0
single bonded oxygen = 6-1-6 so it is -1
sulfur = 6-3-2 so it is +1
Answer:
20 kJ/mol
Explanation:
From ∆G°= -RTlnK
But
Ag2SO4(s)<----------->2Ag+(aq) + SO4^2-(aq)
Ksp= [2Ag+]^2 [SO4^2-]
But Ag+ = 0.032M
Ksp= (2×0.032)^2 (0.032)
Ksp= 1.31072×10^-4
∆G°= -RTlnK
∆G°= -(8.314× 298×(-8.93976))= 20KJmol-1( to the nearest KJ)
Answer: heat required to raise the temperature
Explanation: Heat equation is represented as:
Q= heat required to raise the temperature
m= mass of the substance
c = heat capacity of substance
