In VA, 30% of the electricity generated uses coal. On average, each person in VA uses 1,870 kg of coal per year to generate electricity that they use.
Use stoichiometry to calculate the amount of kilograms of carbon dioxide
produced from 1,870 kg coal. (Must show stoichiometric equation to earn
credit. Hint: 1000 grams = 1 kg)

Phosphoric acid is a triprotic acid ( =6.9×10−3 , =6.2×10−8 , and =4.8×10−13 ). to find the ph of a buffer composed of h2po−4(aq) and hpo2−4(aq) , which p value should be used in the henderson–hasselbalch equation? p k a1 = 2.16 p k a2 = 7.21 p k a3 = 12.32 calculate the ph of a buffer solution obtained by dissolving 18.0 18.0 g of kh2po4(s) kh 2 po 4 ( s ) and 33.0 33.0 g of na2hpo4(s) na 2 hpo 4 ( s ) in water and then diluting to 1.00 l.
