Answer: Thus the % yield is 86.2%
Explanation:
Percentage yield is the ratio of actual change to the theoretical change in terms of percentage.
The given reaction is :
![Mg+2HCl\rightarrow MgCl_2+H_2](https://tex.z-dn.net/?f=Mg%2B2HCl%5Crightarrow%20MgCl_2%2BH_2)
To calculate the percent yield :
![\%\text{ yield of reaction}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20yield%20of%20reaction%7D%3D%5Cfrac%7B%5Ctext%7BActual%20yield%7D%7D%7B%5Ctext%7BTheoretical%20yield%7D%7D%5Ctimes%20100)
Given : Actual pressure increase = 0.25 atm
Theoretical pressure change = 0.29 atm.
![\%\text{ yield of reaction}=\frac{0.25}{0.29}\times 100=86.2\%](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20yield%20of%20reaction%7D%3D%5Cfrac%7B0.25%7D%7B0.29%7D%5Ctimes%20100%3D86.2%5C%25)
Thus the % yield is 86.2%
Answer:
It is called tempering. Its tensile strength may reduce but it will become more rigid and hard to break compared to the original metal.
