The given reactions are combination reaction, decomposition reaction, neutralization reaction, displacement reaction and double displacement reaction.
A displacement reaction is a chemical process during which a one more reactive element being replaced from its compound by a less reactive element.
When A combination reaction occurs when one or more elements or compounds react together to generate a new chemical. Equations of the following kind are used to depict such reactions.

Answer: the answer is B
Explanation:
Because they have to hold them to fill in their spaces.
b. activation energy.
c. catalyst energy.
d. chemical energy.
Activation energy is the energy needed to start a chemical reaction. The correct answer to the given question is option b. activation energy.
The energy needed to get a reaction started is called the activation energy. It is the minimum amount of energy required for a chemical reaction to occur. Activation energy is needed to break the existing bonds in reactant molecules and form new bonds to produce product molecules.
The correct answer to the given question is option b. activation energy.

b. Which of the following statements is true?
A) The average kinetic energy of the ice in cup A is less than that in cup
b.
B)The average kinetic energy of the ice in cup A is greater than that cup in
b.
C)The average kinetic energy of the ice cup A is equal to that in cup
b.
D)The average kinetic energies of the ice in cup A and the ice in cup B are not comparable.
Average kinetic energy is given by the formula:
KE(average) = 3/2*k*T
where k = Boltzmann constant = 1.38*10⁻²³ J/K
T = temperature in Kelvin (K)
Thus, the average KE is dependent only on temperature and independent of mass.
Since the temp in Cup A and B remains the same, the average KE will also be the same.

0.80 M HCl(aq)?
(1) 3.6 mL (3) 20. mL
(2) 5.6 mL (4) 40. mL
Answer: 4) 40 ml
Solution :
According to the neutralization law,
where,
= molarity of NaOH solution = 0.30 M
= volume of NaOH solution = ?
= molarity of HCl solution = 0.80 M
= volume of HCl solution = 15 ml
Now put all the given values in the above law, we get the volume of NaOH solution.
Therefore, the volume of 0.30 M NaOH required to neutralize 15 ml of 0.80 M HCl is 40 ml.
The volume of 0.30 M NaOH(aq) needed to neutralize 15.0 milliliters of 0.80 M HCl(aq) is 40 milliliters.
The volume of 0.30 M NaOH(aq) needed to neutralize 15.0 milliliters of 0.80 M HCl(aq) can be determined using the concept of stoichiometry and the balanced equation for the reaction between NaOH and HCl. The balanced equation is:
NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)
From the balanced equation, we can see that 1 mole of NaOH reacts with 1 mole of HCl. Therefore, the number of moles of HCl in 15.0 milliliters of 0.80 M HCl solution can be calculated as:
Moles of HCl = Volume (in liters) × Molarity = 0.015 liters × 0.80 moles/liter = 0.012 moles
Since 1 mole of NaOH reacts with 1 mole of HCl, we need 0.012 moles of NaOH. The volume of 0.30 M NaOH solution can be determined by rearranging the equation:
Volume (in liters) = Moles / Molarity = 0.012 moles / 0.30 moles/liter = 0.04 liters = 40 milliliters
Therefore, the volume of 0.30 M NaOH(aq) needed to completely neutralize 15.0 milliliters of 0.80 M HCl(aq) is 40 milliliters.
