Clearly volume will INCREASE almost sevenfold, as we would expect if we reduce the pressure. ... Assuming this is an ideal gas, and that the number of molecules *n* of this gas remains constant, and given that the temperature is also ... That is, in these conditions, pressure times volume is constant :
H2se is a ionic bond which requires higher energy to change into a gas, while h2s is a covalent bond requiring less energy
Answer:
No.
Explanation:
The equilibrium amounts relatively do not change depending on the reaction, whether you started with 8 moles of NO2 or 4 moles of NO2.
Answer:
Nickel is extracted from nickel oxide by reduction with carbon. Nickel is a metal which react with atmospheric oxygen which is very reactive in order to protect the inner surface of metal. Carbon extract oxygen which is attached to the nickel in the form of nickel oxide because carbon is more reactive so it made a chemical bonds with oxygen and nickel oxide is converted into a pure nickel.
The maximum mass of B₄C that can be formed from 2.00 moles of boron (III) oxide is 55.25 grams.
<h3>What is the stoichiometry?</h3>
Stoichiometry of the reaction gives idea about the relative amount of moles of reactants and products present in the given chemical reaction.
Given chemical reaction is:
2B₂O₃ + 7C → B₄C + 6CO
From the stoichiometry of the reaction, it is clear that:
2 moles of B₂O₃ = produces 1 mole of B₄C
Now mass of B₄C will be calculated by using the below equation:
W = (n)(M), where
- n = moles = 1 mole
- M = molar mass = 55.25 g/mole
W = (1)(55.25) = 55.25 g
Hence required mass of B₄C is 55.25 grams.
