Answer:

(A) 0.4M NaOH

Explanation:

The 20M NaOH caustic soda is diluted from 10mL to 500mL, that is:

500mL / 10mL = Is diluted 50 times.

That means we can solve the new concentration of the diluted solution dividing the stock concentration (20M) 50 times:

20M / 50 = 0.4M NaOH is the concentration of the diluted NaOH solution.

Right answer is:

<h3>(A) 0.4M NaOH</h3>

The standard molar enthalpy of vaporization for water is 40.79kJ/mol. What mass of steam is required to release 500 kJ of energy
bezimeni [28]

Answer:

220.9g of water are required

Explanation:

The molar enthalpy of vaporization is defined as the heat released when 1 mole of water changes from liquid to gas.

For water, 1 mole releases 40.79kJ. To release 500kJ are necessaries:

500kJ * (1mol / 40.79kJ) = 12.26 moles are necessaries

To convert moles to grams we must use the molar mass (H2O = 18.02g/mol):

12.26 moles * (18.02g / 1 mol) =

One reason for this connection is that when two plates come together quickly, the area over which an earthquake occurs is larger.Explanation:
