An ionic bond is formed between a cation A1 and an anion B2. How would the energy of the ionic bond [see Equation (9.2)] be affe
1 answer:
Answer:
Before we start answering, the appropiate equation for the energy of an ionic bond should be written:
Where A1+, B2- are the charges of the ions and Ro is the interionic distance (the sum of the radii of the anion and cation). C is a constant depending on the ionic structure.
Explanation:
Examining the equation above, we have the following scenarios:
a) Doubling the radius of A1 would mean a decrease on the energy of the ionic bond.
b) Tripling the charge of A1 would also triple the energy of the ionic bond
c)Doubling the charges on A1 and B2 would quadruple the energy of the ionic bond.
d)Decreasing the radii of A1 and B2 to half their original values would double the energy of the energy bond.

Explanation:
Quantity of heat required by 10 gram of ice initially warm it from -5°C to 0°C:
here;
mass, m = 10 g
specific heat capacity of ice,
change in temperature,
Amount of heat required to melt the ice at 0°C:
where,
we know that no. of moles is = (wt. in gram) (molecular mass)
Now, the heat required to bring the water to 70°C from 0°C:
specific heat of water,
change in temperature,
Therefore the total heat required to warm 10.0 grams of ice at -5.0°C to a temperature of 70.0°C:
