The compound name for H3S5 is hydrosulfide sulfanide sulfide
<span>Ka = [H+][PAc-] / [PAcH]
[H+] = 10^-2.68 = 0.00209M = [PAc-]
[PAcH] = 0.085 = 0.00209 = 0.083
Ka = (.00209)(.00209) / (0.083) = Answer Here.</span>
Answer:An accompanying WMO report on greenhouse gas concentrations shows that 2015-2019 has seen a continued increase in carbon dioxide (CO2) levels and other key greenhouse gases in the atmosphere to new records, with CO2 growth rates nearly 20% higher than the previous five years.
Explanation:That's because the annual growth rate of atmospheric carbon dioxide has roughly tripled, from 0.6 ppm per year in the early 1960s to an average 2.1 ppm during the past 10 years. At Mauna Loa, carbon dioxide concentrations in 2015 jumped by 3.05 ppm
Answer:
Triple bond is the strongest bond
Triple bonds are stronger than the equivalent single bonds or double bonds, with a bond order of three.
Answer:
Explanation:
The percent yield is the ratio of the actual yield to the theoretical yield.
- The actual yield is the amount obtained from performing a chemical reaction. For this problem, it is 14.8 grams.
- The theoretical yield is the potential amount from performing a chemical reaction at maximum performance. For this problem, it is 23.5 grams.
We can substitute the known values into the formula.
Divide.
Multiply.
The original measurements for the theoretical and actual yields have 3 significant figures, so our answer must have the same. For the number we calculated, that is the tenths place.
The 7 to the right, in the hundredths place, tells us to round the 9 up to a 0. Since we rounded up to 0, we have to move to the next place to the left and round the 2 up to a 3.
The percent yield is approximately <u>63.0 percent.</u>
