Answer:
molarity 0.1
Explanation:
mass of copper nitrate =2.4
no of moles exist in 120ml= 2.4/187.5=0.0128mole
molarity =.0.0128/.12=0.1m
Answer:
Ca2+ is an ion with a correct charge.
Answer:
a. HI(aq)+NaOH(aq) → H2O(l)+NaI(aq)
b. HBr(aq) +KOH(aq) → H2O(l)+KBr(aq)
c. HNO3(aq)+Ba(OH)2(aq) → BaNO3(aq)+H2O(aq)
D. HClO4(aq)+Sr(OH)2(aq) → SrClO4(aq)+H2O(aq)
Explanation:
In a neutralization reaction, an acid and a base react to form water and salt and involves the combination of H+ ions and OH- ions to generate water.
In this case, the atoms have charge positive and negative, the only thing we have to do is to change in the products taking account that positive with negative an vice-versa.
H+I-(aq)+Na+OH-(aq) → H+2O-(l)+Na+I-(aq)
