This problem can be solved using Ideal Gas of Equation (PV=nRT). Solving for mass, mole is expanded to mass/M. mass. Now having all values in hand , convert temperature from celcius to Kelvin. Below is the solution,

Answer:

Q = 16163.88 Joules

Explanation:

Given the following data;

Initial temperature, T1 = -25°C

Final temperature, T2 = 150°C

Mass = 45.5 g

Specific heat capacity of ice = 2.03 J/g°C

To find the quantity of heat required;

Heat capacity is given by the formula;

Q = mcdt

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

dt = T2 - T1

dt = 150 - (-25)

dt = 150 + 25

dt = 175°C

Substituting into the formula, we have;

Q = 45.5 * 2.03 * 175

Q = 16163.88 Joules

Answer:

V

Explanation:

Firstly let’s list the names of the atoms

1. Sodium

2. Magnesium

3. Aluminum

4. Oxygen

5.Chlorine

Generally, anions have greater electron affinity than cations. Hence, they have more positive values for this electron affinity. This means that the higher the electron affinity, the greater its positive value

Electron affinity increases across a period. Thus, it is expected that chlorine has the highest value
