How many moles of diethyl ether are formed from 14 mil of ethanol?

Which of the following statements about enthalpy is incorrect?
Enthalpy and internal energy of a system are always identical
enthalpy is a state function
$\Delta H$ is the enthalpy change at constant pressure
Reactions which absorb heat have a positive DH

How much potassium bromide should be added to perform formalin test?

A coffee-cup (constant pressure) calorimeter is used to carry out the following reaction in an unknown volume of water (where X is a hypothetical metal):

X + 2 H2O → X(OH)2 + H2

In this process, the water temperature rose from 25.0 °C to 37.1 °C. If 0.00579 mol of "X" was consumed during the reaction, and the ΔH of this reaction with respect to the system is -1278 kJ mol-1 , what volume of water (in mL) was present in the calorimeter?

The specific heat of water is 4.184 J g-1 °C-1

To process certain metal ores, reactions with carbon can sometimes generate the pure metal at high temperatures.

Consider the reaction of zinc oxide with carbon:

ZnO + C → Zn + CO ; ΔH = 240 kJ/mol of rxn

How much heat needs to be absorbed by the system (in kJ) to react 3121 g of ZnO with 351 g of C until the reaction is completed?

Container "A" holds N2 gas with a mass of 54.6 g and is 4.1 times the volume of container "B" which holds argon (Ar) gas at the exact same temperature and pressure. What is the mass of the Ar (in g) within container "B"?
