Answer: D) recording the high and low temperature at a particular location every day.

Explanation:

A experiment is a process which is conducted or performed to either support, refute or validate the hypothesis. It involves the detail repeatable procedure and the logical analysis of the outcomes of the results. It involves different variables which are compared to obtain the outcome of the experiment. For example the amount of water used everyday responsible for the plant height.

Among the options given, D) recording the high and low temperature at a particular location every day. is the correct option, temperature is a variable in the experiment. The change in the daily temperature of a location can be noted as observation of the experiment. This observation can be used to record the average temperature of the location.

Alina [70]

Answer:

<h2>0.059 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

$n = \frac{3.55 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.05897...$

We have the final answer as

<h3>0.059 moles</h3>

Hope this helps you

Answer:

Option D. ZnCl₂ and H₂

Explanation:

From the question given above, the following equation was obtained:

2HCl + Zn —> ZnCl₂ + H₂

Products =?

In a chemical equation, reactants are located on the left side while products are located on the right side i.e

Reactants —> Products

Now, considering the equation from the question i.e

2HCl + Zn —> ZnCl₂ + H₂

The products are ZnCl₂ and H₂ because from our discussion above, we said that products are only located on the right side of chemical equation.

Thus, option D gives the correct answer to the question.
