Answer:The correct answer is option C.
Explanation:
At STP, 1 mol of gas occupies 22.4 L of volume
So, 100.0 L volume of 
will be occupied by :
According to reaction 2 moles are obtained from 1 mole of 
.
Then,4.4642 moles of will be obtained from :
that is 2.2321 moles of
Mass of gas:
Moles of gas Molar mass of gas:
Hence, the correct answer is option C.
Answer:
I think that the statement is relative to speed because it is saying km per second.
4, 2, 1, and 3 is the answer
Answer:
Covalent compounds.
Explanation:
Hello,
In this case, when forming chemical bonds in order to form compounds, we say that if electrons are shared, covalent compounds are to be formed and they usually have subscripts that need prefixes to be named, for instance phosphorous pentachloride (PCl5), dichlorine heptoxide (Cl2O7), carbon tetrachloride (CCl4) and many others.
Regards.
Answer:
Option D is correct.
The concentrations of both PCl₅ and PCl₃ are changing at equilibrium
Explanation:
Chemical equilibrium during a reversible chemical reaction, is characterised by an equal rate of forward reaction and backward reaction. It is better described as dynamic equilibrium.
This is because, the concentration of the elements and compounds involved in the reversible chemical reaction at equilibrium changes, but the rate of change of the reactants is always equal to the rate of change of products.
Hence, the concentration of reactants and products, such as PCl₅ and PCl₃ are allowed to change at equilibrium, but alas, the rate of forward reaction must always match the rate of backward reaction for the process to remain in a state of Chemical equilibrium.
Hope this Helps!!!
