Chemistry
1 answer:
Fudgin [204]3 years ago
6 0

Answer:

3.45 moles Li  contains  2.08 × 10 (to the power of)24  atoms .

Explanation:

The relationship between atoms and moles is:

1  mole atoms =

6.022 × 10 (to the power of)23

atoms

In order to determine how many atoms occupy a given number of moles, multiply the given moles by  

6.022 × 10 (to the power of)23

atoms/mole

.

In the case of 3.45 moles lithium (Li):

3.45 mol Li × 6.022 × 10 (to the power of)23  atoms Li/ 1 mol Li =

2.08 × 10 (to the power of)24

atoms Li  rounded to three

Andru [333]

Answer:

independent variable -- different batteries

dependent variable -- the time that clock stop

Explanation:

In an experiment or a research study, there are two type of variables that can affect the result of the experiment or the conclusion. They are independent variable and the dependent variable.

An independent variable may be defined as that variable in an experiment which can be changed or can be controlled in the scientific experiment in order to test the effect on the dependent variable. It cannot be changed by other variables.

On the other hand, dependent variable are those are those which can be altered or change that can affect the experiment.

In the context, Emily uses  the different types of the batteries as an independent variable and the time where the clock stopped in the dependent variable in her research.
