Your balanced equation for this reaction is:
HCOOH (aq) + H2O (aq) → HCOO- (aq) + H3O+ (aq)
So from the reaction, we can see when formic acid dissolved in water so H3O+ ions will be formed.
and we can see that it is a balanced equation as:
we have H atoms = 4 on both sides of the reaction
and C atoms = 1 atom on both sides of the reaction
and O atoms = 3 atoms on both sides of the reaction
So it is our final balanced equation of the reaction.
Answer:
c
Explanation:
neutrons have no charge
protons and electrons have opposite charges and balance each other out in equal numbers
<u>Answer:</u>
For 1: The correct answer is option D.
For 2: The correct answer is option A.
<u>Explanation:</u>
There are two types of molecules which can be categorized on the basis of electronegativity difference:
Polar molecules: In these type of molecules, the two atoms combining must be different so that a dipole can be created and for that the electronegativity of two atoms combining must not be same. The negative dipole of charge is created on the electronegative atom and positive dipole or charge is created on the electropositive atom.
Hence, the correct answer is option D.
Non-polar molecules are defined as the molecules which do not have any dipole and is formed when two atoms of same element combine together which have the same electronegativity. The electronegativity difference of these molecules is 0.
Hence, the correct answer is A.
Answer:
2.06 × 10⁻¹⁰
Explanation:
Let's consider the solution of a generic compound AB₂.
AB₂(s) ⇄ A²⁺(aq) + 2B⁻(aq)
We can relate the molar solubility (S) with the solubility product constant (Kps) using an ICE chart.
AB₂(s) ⇄ A²⁺(aq) + 2B⁻(aq)
I 0 0
C +S +2S
E S 2S
The solubility product constant is:
Kps = [A²⁺] × [B⁻]² = S × (2S)² = 4 × S³ = 4 × (3.72 × 10⁻⁴)³ = 2.06 × 10⁻¹⁰
Carbon atoms oxidation number is +2.Hydrogen's oxidation number is +1.Oxygen's oxidation number is -2.
