Answer:

3.6 × 10²⁴ molecules

Explanation:

Step 1: Given data

Moles of methane (n): 6.0 moles

Step 2: Calculate the number of molecules of methane in 6.0 moles of methane

In order to convert moles to molecules, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ molecules of methane in 1 mole of molecules of methane.

6.0 mol × 6.02 × 10²³ molecules/1 mol = 3.6 × 10²⁴ molecules

For cm to m, you need to divide by 100 to get m:
26cm/100= 0.26m

For hr to min, you need to multiply by 60 to get min:
4hr x 60= 240min

For km to m, you need to multiply by 1000 to get m:
3.25km x 1000= 3250m

For ft to in, you need to multiply by 12 to get in:
5ft x 12=60in

So we have:
0.26m
240min
3250m
60in

Explain combination reaction

MAXImum [283]

A combination reaction (also known as a synthesis reaction) is a reactionwhere two or more elements or compounds (reactants) combine to form a single compound (product). Such reactions may be represented by equations of the following form: X + Y → XY.

Which of the following would not cause an increase in the pressure inside a sealed container of neon gas?

r-ruslan [8.4K]

The pressure in a sealed container means the volume of container is fixed

so we cannot change the volume of container hence gas

The other factors which can affect the pressure are

a) moles of gas : if we increase the moles of gas the pressure of gas will increase

b) Temperature: if we increase the pressure of gas the pressure of gas will increase due to increase in kinetic energy

So the following cannot increase pressure

a) decrease in moles of gas

b) decrease in temperature of gas

Constants (“controlled variables”) and a control are easily confused by students! How would you explain the difference between t

Deffense [45]

Answer:

Please find the explained difference below

Explanation:

In a scientific experiment, the CONTROLLED VARIABLE, also known as CONSTANT, is the the variable that is kept unchanged by the experimenter throughout the course of the experiment. The constants are not part of the actual experiment but altering them can influence its outcome.

A control group is one of the two groups in an experiment (the other being experimental group) that doesn't receive the variable being manipulated (independent variable). The control group is the same as the experimental group except that the independent variable is unchanged in the control group. It is used to make a comparison with the experimental group.

For example, in an experiment to test the effect of sunlight on plant growth. Some plants were exposed to sunlight while some were placed in the dark. The CONTROL group of this experiment are the plants placed in the dark (no light). They didn't receive any treatment.

The constants of this experiment can be same amount of water, same type of plants used etc. This is done in order not to affect the outcome of the experiment.
