Answer:
B. a strongly basic solution
Explanation:
Kb is base dissociation constant, which indicates how completely a base dissociates into its component ions in water. The greater the Kb value, the greater the alkalinity of the solution and vice versa.
Therefore, a solution with a Kb value much greater than 1, indicates a strongly basic solution, while a solution with a Kb value less than 1, indicates a weakly basic solution.
You can reduce wind erosion by providing a protective plant cover for the soil.
Answer:
a. The fish are dying due to factory pollution making the water of the pond uninhabitable.
b. The pond can be neutralized by adding something basic to balance the pH levels of the pond, or by adding significant amounts of water to dillute the acidity of the pond.
Answer:
Yes
Explanation:
The combination of an acid and base causes a chemical reaction. The product is a gas, bubbles that are carbon dioxide. The carbon dioxide gas is trapped in the balloon and it inflates. The carbon dioxide gas molecules created a pressure by colliding with the sides of the balloon.
Answer: 1. A. testable
2.new observations
Explanation:
A scientific theory is the one which explains the cause of a natural phenomena through observatory and experimentation approach. It is valid, accurate and acceptable worldwide.
1. It is testable by implementation of suitable methodology for the purpose of proving the cause of the natural phenomena occurring in nature.
2. A the explanation of the theory can be changes on the basis of the new observations obtained after implementation of new technology and methodology.
