246.24+238.278+98.3 Calculate to the appropriate number of significant figures

Chemistry
1 answer:
lilavasa [31]3 years ago
3 0

Answer:

The correct answer is 582.8.

Explanation:

To solve this problem, we must remember the rules for significant figures for addition.  Recall that the answer should have the same number of decimal places as the term with the least number of decimal places that we are adding.  In this case, we can see that out of our three terms, 98.3 has the least number of decimal places.  This lets us know that our answer should be rounded to the tenths place.

With this in mind, we can compute the addition.

246.24 + 238.278 + 98.3

= 582.818 (unrounded value)

However, we stated that our answer should be rounded to the tenths place.

Therefore, our answer is 582.8.

Hope this helps!

Arrange the following in order of increasing bond strength of the carbon oxygen bond:
icang [17]

Answer: Option (d) is the correct answer.

Explanation:

It is known that length of a bond is inversely proportional to the bond strength. This also means that a single bond has long length due to which it is weak in nature.

And, a double bond is shorter in length and has more strength as compared to a single bond. Whereas a triple bond has the smallest length and it has high strength as compared to a double or single bond.

For example, carbon monoxide is CO where there is a triple bond between the carbon and oxygen atom.

Carbon dioxide is CO_{2} where there exists a double bond between the carbon and oxygen atom.

A carbonate ion is CO^{2-}_{3} when two oxygen atoms are attached through single bond with the carbon atom and another oxygen atom is attached through a double bond to the carbon atom.

Hence, we can conclude that order of increasing bond strength of the given carbon oxygen bond is as follows.

        Carbonate ion < carbon dioxide < carbon monoxide
