Kathy was making liquid growth medium for plants. The pH of the original solution was 8. The optimal pH for plant growth is 6. W
liubo4ka [24]

If referring to the question: Kathy was making liquid growth medium for plants. The pH of the original solution was 8. The optimal pH for plant growth is 6. What was the best compound to add to make it pH=6?

A) KOH

B) HCL

C) Water

D) No answer provided

Then the correct answer would be option B, to add HCL, known as Hydrochloric acid to lower the pH to 6.

In science, pH is a scale used to measure the acidity of a solution or its basicity. The scale ranges from 0 to 14. A pH of 7 would mean that the given solution is neutral, lower than 7 equates to an acidic solution, while anything above 7 becomes increasingly basic.

Option A is to add KOH, or potassium hydroxide to the original solution whose starting pH is 8. KOH is a solution whose pH is above 8,  a strong base, and is often used to increase the pH of a solution. In the question it states what the desired pH is 6, therefore we want to lower, not increase the pH. This makes option A incorrect.

Water is a neutral solution. Even though it is neutral, it is not used to neutralize basic or acidic solutions. Acid or bases may be added to water to create very diluted solutions that are nearly neutral despite containing a strong base or acid, but this is a different process than neutralization and will not give the desired pH. Option C is also wrong.

Option B is correct because HCL, known as hydrochloric acid is a strong acid, commonly used to lower the pH of a solution by increasing the concentration of hydrogen ions. Since we start with a pH of 8 and wish to achieve a pH of 6, HCL is the correct component to add to the solution. Due to option B being correct, option D that states that no answer is provided, is incorrect.

How do cricket communicate temperature and reactions and body parts allow them to do this?
aleksley [76]

Answer:

as temperature rises, mussles in a crickets body contract more, causing it to chirp more often

Explanation:Crickets, like all living things, have many chemical reactions going on inside their bodies, such as reactions that allow muscles to contract to produce chirping. Crickets, like all insects, are cold-blooded and take on the temperature of their surroundings. This affects how quickly these chemical muscle reactions can occur. Specifically, a formula called the Arrhenius equation describes the activation, or threshold, energy required to make these reactions occur. As the temperature rises, it becomes easier to reach a certain activation energy, thereby allowing chemical reactions, such as the ones that allow a cricket to chirp, to occur more rapidly.
