Answer: The pH of the substance is 8.25. The solution is basic.
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydronium ion concentration. The acids have pH ranging from 1 to 6.9 , salts have pH of 7 and bases have pH ranging from 7.1 to 14.
Putting in the values:
Thus as pH is more than 7, the solution is basic.
The pH of the substance is 8.25. The solution is basic.
Answer:
82.6 moles
Explanation:
chemical equation:
CO2+ 4H2 → CH4 + 2H2O
Given data:
moles of carbon dioxide = 82.6 mol
moles of methane = ?
through the balanced chemical equation we will compare the moles carbon dioxide with methane
CO2 : CH4
1 : 1
82.6 : 82.6
we are given hydrogen so 82.6 moles of carbon dioxide will produce 82.6 moles of methane.
False
because it’s outside of the country!
good luck :)
Answer:
Below.
Explanation:
Because of the hydrogen bonding that occurs in water. Oxygen is more electronegative than sulphur and forms inter molecular bonding between the H+ and O- ions in the water. This does not occur in H2S.
