Hydrogen should be your final answer.
The increase in the average kinetic energy of the molecules needs the increase of temperature. The relation of ℃ and K is n ℃ = m K -273. So if we change all the K unit to ℃ unit, we can get the answer is (1).
The statement is true as all Ionic compounds are called Electrolytes because they dissociate(break apart) in water to form a solution that conducts electric current.
Explanation:
An ionic compound also called an electrolyte. Ionic compounds have capability to get dissociate into water to give ions(cation and anion) which conduct electric current. This process is called conductivity.
Some insoluble compounds that are not dissolved in water still they form ions which conduct electricity.
The cations and anions released are responsible for carrying current.
Strong acids and strong bases are the strong electrolytes as they dissociate to give more ions as NaOH, HCl.
The cations move to the cathode and anions towards the anode. Cation and anion movement in the solution is electric current.
Answer is: 0.102 moles of HCl would react.
Balanced chemical reaction:
2HCl(aq) + Sr(OH)₂ → SrCl₂(aq) + 2H₂O(l).
V(Sr(OH)₂) = 37.1 mL ÷ 1000 mL/L.
V(Sr(OH)₂) = 0.0371 L; volume of the strontium hydroxide solution.
c(Sr(OH)₂) = 0.138 M; molarity of the strontium hydroxide solution.
n(Sr(OH)₂) = c(Sr(OH)₂) · V(Sr(OH)₂).
n(Sr(OH)₂) = 0.0371 L · 0.138 mol/L.
n(Sr(OH)₂) = 0.0051 mol; amount of the strontium hydroxide.
From balanced chemical reaction: n(Sr(OH)₂) : n(HCl) = 1 : 2.
n(HCl) = 2 · n(Sr(OH)₂).
n(HCl) = 2 · 0.0051 mol.
n(HCl) = 0.0102 mol; amount of the hydrochloric acid.
Used in perfumes, face washes, lotions, shampoos, conditioners, etc. They need to be aware because if a perfume had a scent that did not smell right or "pretty" then noone would want to buy their product.
