Answer:
The H+ atoms will become neutralized by the OH- ions in the water. This is due to the fact that when acids are dissovled in water, they give H+ ions (Hydrogen ions). When the H+ ions from the acid join with the OH- ions in the base (water), they'll become neutralized and form H₂O (Water molecule).
Answer: -
Molality of NaCl = 2.807 ×10⁻² m
Explanation: -
Molarity given = 2.800×10⁻² M
This means there are 2.800×10⁻² moles of NaCl per 1000 mL of solution.
Volume of water = 999.2 ml
Density of water = 0.9982 g/ml
Mass of water = Density of water x Volume of water
= 0.9982 g/ml x 999.2 ml
= 997.4 g
Thus 997.4 g of water has 2.800×10⁻² moles of NaCl.
1000 g of water has
x 2.800×10⁻² moles of NaCl.
= 2.807 ×10⁻² moles of NaCl.
Molality of NaCl = 2.807 ×10⁻² m
Answer: B. A secondary pollutant
An acid rain is an example of a secondary pollutant because it is a chemical reaction of two gases namely, the sulfur dioxide and the nitrogen dioxide. The acid rain is not also directly emitted by the atmosphere.
Answer:
Explanation:
The process of gaining or losing electrons from a neutral atom or molecule is called ionization. Atoms can be ionized by bombardment with radiation, but the more purely chemical process of ionization is the transfer of electrons between atoms or molecules
