When Raymond observes certain natural phenomena, he often forms ideas about their causes and effects. Suppose that Raymond surmi

ses that leaves change color in autumn due to scarcity of sunlight. In order to test whether his idea is accurate, he must first construct a falsifiable that defines a clear relationship between two variables. Raymond’s next step is to that would isolate and test the relationship between the two variables. This task can be pretty daunting because Raymond will need to identify and eliminate any variables that could confuse test results.

Answer:

The two variables involved here are sunlight and color of the leaves.

A statement is falsifiable if some observation might show it to be false. In this case, the falsifiable is:  leaves change color in autumn due to scarcity of sunlight. If anybody observes leaves with no change in color after a scarcity of sunlight, then the hypothesis is false.

How many carbon atoms are there in .500 mol of CO2?
AURORKA [14]

Answer: There are 3.011 \times 10^{23} atoms present in 0.500 mol of CO_{2}.

Explanation:

According to the mole concept, there are 6.022 \times 10^{23} atoms present in 1 mole of a substance.

In a molecule of CO_{2} there is only one carbon atom present. Therefore, number of carbon atoms present in 0.500 mol of CO_{2} are as follows.

1 \times 0.500 \times 6.022 \times 10^{23}\\= 3.011 \times 10^{23}

Thus, we can conclude that there are 3.011 \times 10^{23} atoms present in 0.500 mol of CO_{2}.
