What is the force caused by wind pushing on a building?

1 answer:

There are three types of wind load or wind forces.

Uplift load is the first one; this is when the wind flow pressures create a strong lifting effect. Wind flow under the roof pushes upward, while wind flow over the roof goes upward.

What is the pH of 0.000134 M solution of HCI?

mafiozo [28]

Answer: The pH will be 3.87

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

$pH=-\log [H^+]$

$HCl\rightarrow H^++Cl^{-}$

According to stoichiometry,

1 mole of $HCl$ gives 1 mole of $H^+$

Thus $0.000134$ moles of $HCl$ gives = $\frac{1}{1}\times 0.000134=0.0001342$ moles of $H^+$

Putting in the values:

$pH=-\log[0.000134]$

$pH=3.87$

Thus the pH will be 3.87
