Writing down chemical processes is called .

Correct! Wrong!

Chemical reactions are typically written from left to right. The reactants, which are the substances that undergo a chemical change, are written on the left side of the reaction arrow. The products, which are the new substances formed as a result of the reaction, are written on the right side of the arrow. The arrow itself represents the direction of the reaction.

In only five minutes, a burrito artist can create 14 burritos. In one hour, how many burritos can she produce?

Correct! Wrong!

To find out how many burritos the burrito artist can make in one hour, we need to determine the number of 5-minute intervals in an hour.

There are 60 minutes in an hour, and since the artist can make 14 burritos in 5 minutes, the number of burritos made in one hour can be calculated as follows:

Number of burritos in one hour = (Number of burritos in 5 minutes) * (Number of 5-minute intervals in an hour)

Number of burritos in one hour = 14 * (60 / 5)

Number of burritos in one hour = 14 * 12

Number of burritos in one hour = 168

Therefore, the burrito artist can make 168 burritos in one hour.

A strong acid is which of the following?

Correct! Wrong!

HCl (hydrochloric acid) is indeed a strong acid.

The evolutionary ancestor of both fungus and plants, according to scientists, was:

Correct! Wrong!

Scientists hypothesize that the evolutionary ancestor of both plants and fungi was a group of protists. Protists are a diverse group of eukaryotic microorganisms that do not fit into the kingdoms of animals, plants, or fungi. They exhibit a wide range of characteristics and lifestyles, including photosynthetic capabilities like plants and heterotrophic modes like fungi. The common ancestor of plants and fungi is believed to have diverged from a protist ancestor, eventually leading to the evolution of distinct lineages for plants and fungi.

Scientists have proposed that ____ are the evolutionary ancestors of protists that resemble plants, such as red and green algae, based on DNA analysis.

Correct! Wrong!

Why does activation energy exist?

Correct! Wrong!

Activation energy is the minimum amount of energy required for a chemical reaction to occur and for the reactant molecules to transform into products. It represents the energy barrier that must be overcome for the reaction to proceed.

Out of 222, what percentage is 122?

Correct! Wrong!

To calculate the percentage of 122 out of 222, you can use the following formula:

(122 / 222) * 100

Dividing 122 by 222 gives us 0.5495. Multiplying this by 100 gives us 54.95.

Therefore, 122 out of 222 is approximately 54.95 percent.
