Chemistry

The first rule is to use four digits in atomic weights and consider the calculated formula or molar mass as given with four significant digits. This rule is appropriate for beginners but has some disadvantages.

The second rule is to use all digits in the recommended atomic weights and to estimate the accuracy of the result from the number of decimal places or significant digits in these.

The third rule is to use all digits in the recommended atomic weights and to calculate the absolute maximum uncertainty of the result from the recommended uncertainties of the atomic weights. The uncertainty is rounded up to one (two) significant digit(s), and the formula or molar mass is rounded to the same absolute accuracy as the rounded uncertainty.

What is the full number for 5.7x10^4
dsp73

Answer:

5.7*10^4 is equal to 57,000.

Explanation:

First, we must multiply 10 by its power, 4. That would be 10 4 times.

10*10*10*10 = 10,000.

Then, we multiply it by 5.7.

5.7*10,000 = 57,000.

Name the following compound:
igomit [66]

Answer:

3,5-dimethyl-2-octene

Explanation:

When naming an organic molecule with a double bond, the chain has to include the double bond.  This means that there are 8 carbon atoms on the central chain.  The molecule is octene.  The double bond is after the second carbon, making it 2-octene.  You can't say that its 6-octene because you want to have the smallest number possible in front.

The molecules attached are two methyl groups.  Since you have two methyl groups, the name will be dimethyl.  Start counting from the side closest to the double bond.  This gives you a 3, 5-dimethyl group.
