Apellet of zn of mass 10.0g is dropped into a flaskcontaining
dilute h2so4 at a pressure of p=1.00 bar and
temperature of 298k. what is the reaction thatoccures? calculate w
for the process.

Work done for the process is -390 J

Explanation:

The chemical equation for the reaction of zinc metal with sulfuric acid follows:

To calculate the number of moles, we use the equation:

Given mass of zinc = 10.0 g

Molar mass of zinc = 65.38 g/mol

Putting values in above equation, we get:

The equation given by ideal gas follows:

where, P = pressure of the gas

= Change in volume of the gas

T = Temperature of the gas = 298 K

R = Gas constant = 8.314 J/mol.K

n = number of moles of gas = 0.153 mol

Putting values in above equation, we get:

To calculate the work done, we use the equation:

Hence, work done for the process is -390 J

the answer is true.
