Answer:
b. in the middle
Explanation:
your answer choice is correct!
Take the given 2.00 moles of hydrogen then divide it by 1 mole of hydrogen. Second you want to multiply the answer by 22.4L. Giving you an answer of 44.8L of hydrogen
Answer: the effective nuclear charge of sulfur is less than that of chlorine
Explanation:
Ionization Energy can be defined as the energy needed for the complete removal of valence electron.
Ionization Energy decreases steadily down the group because of the outer electrons becomes progressively separated from the nucleus, hence they are less tightly held.
Also, Ionization Energy increases from left to right across the period i.e formation of a cation becomes more difficult owing to increase in nuclear charge.
Therefore, the effective nuclear charge of sulfur is less than that of chlorine because Chlorine have a greater ionization energy.
Answer: 75.7 % yield
Explanation:
The balanced chemical equation is:
According to stoichiometry :
68.2 g of 
will require = 64 g of 
Thus 7.5 g of will require = 
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 68.2 g of give = 96 g of
Thus 7.5 g of give =
of 
% yield=
Thus 75.7 % yield is there.
Answer:
According to the collision theory, we can increase the rate of a reaction by increasing the concentration of reactants. We can also increase the rate of a reaction by increasing temperature to safe levels.
In the reaction mentioned in the question, Mg + 2HCl → MgCl2 + H2, if we increase the amount of magnesium or HCl, the reaction will proceed faster. Similarly, if we increase the temperature, then also the reaction rate will increase.
