The student originally has 252 grams of water in this experiment.
LAW OF CONSERVATION OF MASS:
- The law of conservation of mass explains that matter (mass) can neither be created nor destroyed but can be changed from one form to another.
- This means that in a chemical reaction, the sum of the masses of the reactants must equate to the total mass of product(s).
- According to this question, a student conducts an experiment to separate water into hydrogen and oxygen. The student collects 28.0 g of hydrogen and 224.0 g of oxygen.
- Since hydrogen and oxygen are the constituent elements of water, the sum of their masses must equate the mass of water.
- Therefore, 224g of oxygen + 28g of hydrogen = 252g of water.

Answer:
The answer to your question is below
Explanation:
See the attachment.
Synthesis ΔH
ΔH = 25 - (-30) = 25 + 30 = 55 kJ Endothermic reaction
Single reaction
ΔH = 30 - 65 = -35 KJ Exothermic reaction
Double reaction
ΔH = 60 - 10 = 50 kJ Endothermic reaction
Answer:
Below:
Explanation:
The Contact process If the temperature is increased, the equilibrium position moves in the direction of the endothermic reaction. This means it moves to the left in the Contact process. ... However, the rate of reaction is low at low temperatures. So, as in the Haber process, a compromise temperature of 450 °C is chosen.
Habar Process...
The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first decade of the 20th century.
