2. Calculate the combustion temperature of a gaseous oxygen-hydrogen mixture whose mass ratio is 3: 1 (02: H2). Since this means a considerable excess of hydrogen over the stoichiometric proportion, assume that the product temperature will be low enough to prevent dissociation. The temperature of the reactants entering the chamber is 298 K, and the heat transfer to the coolant from the chamber walls is 8.4 kJ per mole of product. As a first app

How have the greenhouse gasses increased from the year 2000 to 2018

Suppose that a certain fortunate person has a net worth of $71.0 billion ($7.10×1010). if her stock has a good year and gains $3.20 billion (3.20×109) in value, what is her new net worth?

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.
