I think I found it. It was a cylinder
Answer:
HCOOH, H₃O⁺, and HCOO⁻
Explanation:
HCOOH is the major solute.
However, HCOOH is a weak acid. It dissociates slightly in aqueous solution.
HCOOH + H₂O ⇌ HCOO⁻ + H₃O⁺
Thus, two other solute particles are HCOO⁻ and H₃O⁺.
Answer:
negative charge electrode
Explanation:
In cathode positive ions are picked up to perform reduction.At the same time negative ions are picked up at anode to get oxidized from electrolyte.
Answer:
15.14×10⁷ g
Explanation:
Given data:
Number of particles of NaCl = 1.56×10³⁰ particles
Mass of sodium chloride = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ particles
1.56×10³⁰ particles × 1 mol / 6.022 × 10²³ particles
0.259 ×10⁷ mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 0.259 ×10⁷ mol × 58.44 g/mol
Mass = 15.14×10⁷ g
