A change of one unit on the pH scale represents a change in the concentration of hydrogen ions by a factor of 10, a change in two units represents a change in the concentration of hydrogen ions by a factor of 100. Thus, small changes in pH represent large changes in the concentrations of hydrogen ions.
<u>Answer:</u> The value of 
for the given chemical reaction is 0.1415
<u>Explanation:</u>
Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of the products and the reactants each raised to the power their stoichiometric ratios. It is expressed as
For a general chemical reaction:
The expression for is written as:
For the given chemical equation:
The expression for for the following equation is:
We are given:
Putting values in above equation, we get:
The value of for the given chemical reaction is 0.1415
There are no similarities between the two, though there are many differences!<span />
Answer:
Relative humidity
Explanation:
A psychrometer measures the relative humidity in the atmosphere with the help of two thermometers:
1) A dry bulb thermometer:
It is used to measure the temperature by being exposed to the air.
2) A wet bulb thermometer:
It measures temperature by having the bulb dipped in a liquid.
The value of x is 38 and y is 104.
