In a reaction, gaseous reactants form a liquid product. The heat absorbed by the surroundings is 1.1 MJ, and the work done on th
ratelena [41]

Answer: \Delta E is 1155 kJ

Explanation:

According to first law of thermodynamics:

\Delta E=q+w

\Delta E=Change in internal energy

q = heat absorbed or released

w = work done or by the system

w = work done by the system=-P\Delta V  {Work done on the system is positive as the final volume is lesser than initial volume}

w =13.2kcal=55.2kJ   (1kcal=4.184 kJ)

q = +1.1 MJ = 1100 kJ  (1MJ=1000kJ)   {Heat absorbed by the system is positive}

\Delta E=1100kJ+(55.2)kJ=1155kJ

Thus \Delta E is 1155 kJ

How many moles of HCl are present in 0.70 L of a 0.33 M HCl solution? (molar mass of HCl = 36.46 g/mol)
Vilka [71]

Answer:-

0.231 moles

Explanation:-

From the question we are told that

Volume of HCl solution = 0.70 L

Strength of HCl solution = 0.33 M

Here M stands for molarity. Molarity is the number of moles of the substance present per Litre of solution. So in place of M we can write moles / L

Number of moles of HCl solution = Volume of HCl solution x Strength of HCl solution

= 0.70 L x 0.33 moles / L

= 0.231 moles.

0.231 moles of HCl are present in 0.70 L of a 0.33 M HCl solution
