<u>Answer:</u> The partial pressure of hydrogen is 705.9 mmHg
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the partial pressure of hydrogen gas, we use the law given by Dalton, which is:
We are given:
Total pressure of the collection tube, = 729.8 mmHg
Vapor pressure of water, = 23.8 mmHg
Putting values in above equation, we get:
Hence, the partial pressure of hydrogen is 705.9 mmHg
Answer:
pH = 12.2
Explanation:
Given data:
Mass of lime = 0.69 g
Volume = 1535 mL (1535 / 1000 = 1.535 L)
pH of solution = ?
Solution:
First of all we will determine the molarity.
Molarity = moles of solute / volume in litter
Number of moles = mass / molar mass
Number of moles = 0.69 g / 56.1 g/mol
Number of moles = 0.0123 mol
Molarity = moles of solute / volume in litter
Molarity = 0.0123 mol / 1.535 L
Molarity = 0.008 M
One mole of CaO neutralize two mole of OH⁻.
0.008 M×2 = 0.016 M
[OH⁻] = 0.016 M
pOH = -log [OH⁻]
pOH = [0.016]
pOH = 1.8
14 = pH +pOH
pH = 14 - pOH
pH = 14-1.8
pH = 12.2

An amorphous solid is defined as one lacking crystalline structure. Since it doesn’t have structure, it breaks to form a relatively random, jagged edges rather than straight ones it may tend to shatter in prices rather than cleave along a crystal plane l (since there is no crystal plane to break along)
