Answer:
The equilibrium will move in forward direction.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
On addition of base at the equilibrium, the hydroxide ions of the base will neutralize the hydrogen ions and lowering in concentration of hydrogen ion will be observed.
So, on lowering of concentration of hydrogen ions the equilibrium will move in direction in accordance to Le Chatelier’s Principle .The equilibrium will move in forward direction.
Answer:
Acid spills should be neutralized with sodium bicarbonate and then cleaned up with a paper towel or sponge.
Explanation:
Answer:
9.3 × 10²³ molecules
Explanation:
Given data:
Mass of methane = 24.7 g
Number of molecules = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
For 24.7 g methane:
Number of moles = mass/ molar mass
Number of moles = 24.7 g/ 16.04 g/mol
Number of moles = 1.54 mol
1 mole = 6.022 × 10²³ molecules
1.54 × 6.022 × 10²³ molecules
9.3 × 10²³ molecules
The charge is +1 because there are 11 positive protons and 10 negative electrons.
