Question:
The options are;
a. 10. mL of 1 M HCl(aq) at 10.oC
b. 10. mL of 1 M HCl(aq) at 25oC
c. 10. mL of 3 M HCl(aq) at 10.oC
d. 10. mL of 3 M HCl(aq) at 25oC
Answer:
The correct option is;
d. 10 mL of 3 M HCl(aq) at 25 °C
Explanation:
Factors that influence the rate of the reaction include;
Concentration and
Temperature
Concentration
An increase in concentration leads to a increased number of interaction among the the reacting components of HCl and iron filings such that the number of effective interaction or the rate of the reaction increases, therefore, a 10 mL 3 M HCl will react faster than a 10 mL of 1 M HCl.
Temperature
When the temperature of the reacting HCl is increased, the energy within the reacting system increases leading to an increase in the number of high energy collisions which results in an increased reaction rate, therefore, HCl at 25 °C will react faster than HCl at 10 °C.
Hence the correct option is 10 mL of 3 M HCl(aq) at 25 °C.

The <span>simple machine found on the head of the ax is </span>Wedge. A wedge is an inclined plane that can be moved. When an ax is used
to split wood, the ax handle
exerts a force on the blade of
the axe, which is the wedge. That force pushes the wedge
down into the wood. The wedge in turn exerts an
output force splitting the wood in two.
