If two gases react, compressing the gases generally increases the rate of reaction.
What is Collision Theory ?
It states that a chemical reaction can occur the reacting particles must hit each other is called Collision theory.
What is a Chemical Reaction ?
A chemical reaction is a process in which the chemical bonds between atoms to break and reorganize, to form other new substances. In chemical reaction matter cannot be created or destroyed. It is called the law of conservation of mass.
Thus from the above conclusion we can say that If two gases react, compressing the gases generally increases the rate of reaction.

The molarity of the HCl acid is 0.480 M. The correct option is 2.
What is molarity?
Molarity is the division of the mass of the solution to the volume of the solution.
The formula that is used is
Putting the values in the equation
0.620 * 12.7 = M1 * 16.4 = 0.480
Thus, the molarity of the HCl acid is 2). 0.480 M.

Molarity is equal to the moles of solute over liters of solvent. In getting the molarity of HCl, you must know the formula for two solutions which is equal to M1V1 = M2V2. (16.4 milliliters of HCl)M1 = (12.7 milliliters) (0.620 M KOH) and you have 0.480M HCl. The answer is number 2.

Answer:
Rubidium (Rb)
Explanation:
Ionization Energy is defined as, "the minimum energy required to knock out or remove the valence electron from valence shell of an atom".
Trends in Periodic table:
Along Periods:
Ionization Energy increases from left to right along the periods because moving from left to right in the same period the number of protons (atomic number) increases but the number of shells remain constant hence, resulting in strong nuclear interactions and electrons are more attracted to nucleus hence, requires more energy to knock them out.
Along Groups:
Ionization energy decreases from top to bottom along the groups because the number of shells increases and the distance between nucleus and valence electrons also increases along with increase in shielding effect provided by core electrons. Therefore, the valence electrons experience less nuclear attraction and are easily removed.
Conclusion:
Given elements belong to same group hence, Rubidium present at the bottom of remaining elements will have least ionization energy due to facts explained in trends of groups above.

(0.0143L HCl)x(0.1M HCl)=0.00143 moles HCl
Since HCl reacts with KOH in a one to one molar ratio (KOH+HCl⇒H₂O+KCl), the number of moles HCl used to neutralize KOH is the number of moles KOH. Therefore the 25mL solution had to contain 0.00143mol KOH.
To find the mass of KOH in the original mixture you have to divide the number of moles of KOH by the 0.025L to find the molarity of the KOH solution..
(0.00143mol KOH)/(0.025L)=0.0572M KOH
Since the morality does not change when you take some of the solution away, we know that the 250mL solution also had a molarity of 0.0572. That being said you can find the number of moles the mixture had by multiplying 0.0572M KOH by 0.250L to get the number of moles of KOH.
(0.0572M KOH)x(0.250L)=0.0143mol KOH
Now you can find the mass of the KOH by multiplying it by its molar mass of 56.1g/mol.
0.0143molx56.1g/mol=0.802g KOH
Finally you can calulate the percent KOH of the original mixture by dividing the mass of the KOH by 5g.
0.802g/5g=0.1604
the original mixture was 16% KOH
I hope this helps.
