Strong acid on combining with strong base will always give neutral solutions. Consider the following example for the same
HCl + NaOH ↔ NaCl + H2O
(strong (strong
acid) base)
In above case, the resultant solution is neutral in nature.
On other hand, weak acid will react with strong base to form salt and water. But the solution will be basic in nature. Also, strong acid will react with weak base to form salt and water. But the solution will be acidic in nature
Answer:
D) a four-fold increase
Explanation:
According to Gay-Lussac's law, which states that the pressure of a given amount of gas is directly proportional to the temperature at a constant volume, the pressure increases with an increase in temperature.
According to this question, at a fixed volume, a four-fold increase in the temperature of a gas will lead to a four-fold increase in the pressure as well.
They are important because they are the electrons that help the atom to bond with another atom. They are in the outer most shell. ☺️
