Use the following information to calculate the amount of energy (in KJ) required to heat 14.3 g of ethanol from 40oC to 90oC. MW = 46 g/mol

B. P. = 78oC

Heat of vaporization = 841 J/g

specific heat of liquid = 112.4 J/(mol K)

specific heat of gas = 78 J/(mol K)

Round your final answer to a whole number

Click the button that shows the correct relationship of the electron affinities of the elements sodium and phosphorus. sodium’s electron affinity value is more negative than the electron affinity value of phosphorus. phosphorus’ electron affinity value is more negative than the electron affinity value of sodium. this information cannot be determined using the periodic table. answer is b on e2020.

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.

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?
