Perform the following calculations, then round off each answer to the proper number of significant figures: 1210.0 g + 157.22 g
ohaa [14]

Answer:- 1337 g

Solution:- For mathematical operations we use PEMDAS. P stands for parenthesis off, E stands for exponents, M stands for multiplication, D stands for division, A stands for addition and S stands for subtraction. All the mathematical operations are done in this sequence.

What we have given in the problem is, 1210.0 g + 157.22 g - 30. g

Here we have addition and subtraction. As per the law, we will do addition first. In addition and subtraction we go with least number of decimal places.

1210.0 has one decimal place where as 157.22 has two decimal places, since the first number has least decimal places(one decimal place), the answer should also have only one decimal place.

1210.0 g + 157.22 g = 1367.2 g

Now, we will do subtraction. 30. does not have any decimal place and so on subtraction the final answer must not have any decimal places.

1367.2 g - 30. g = 1337 g

So, the final answer is 1337 g.

The attraction between molecules of methane in the liquid state is primarily due to
ivanzaharov [21]

Answer:

Attraction between molecules of methane in liquid state is primarily due to "London dispersion force".

Explanation:

Methane is a non-polar and aprotic molecule. Hence there is no dipole moment in methane as well as no chance of hydrogen bonding formation by methane.

We know that all molecules contain electrons. Therefore transient dipole arises in every molecule due to revolution of electrons around nucleus in a non-circular orbit. Hence an weak intermolecular attraction force is always present in every molecule as a result of this which is termed as "London dispersion force".

So, attraction between molecules of methane in liquid state is primarily due to "London dispersion force".
