Answer:
Explanation:
As the above statement says two carbon atoms are bonded to each other with double bond, the suffix used for double bond is -ene & the prefix for two carbon atoms is eth- & it says four Hydrogen atoms are attached to carbons, 2 Hydrogens to each carbon above & below.
When we draw the structural formula it comes out that the molecule is ethene.

KH₂PO₄ hydrolyzes as;
H₂PO₄⁻ + H₂O ↔ H₃PO₄ + OH⁻
Let x amount of H₂PO₄⁻ has reacted with water then,
Kb₁ = [H₃PO₄][OH⁻] / [H₂PO₄⁻]
[H₂PO₄⁻] = 0.8-x M
Kb₁ = x² / (0.8 - x)
Given Ka₁ = 7.5 x 10⁻³
so Kb₁ = 1 x 10⁻¹⁴ / (7.5 x 10⁻³) = 1.33 x 10⁻¹²
From this information:
1.33 x 10⁻¹² = x² / 0.8
x = [OH⁻] = 1.03 x 10⁻⁶ M
pOH = - log (1.03 x 10⁻⁶) = 5.99
pH = 14 - pOH = 14 - 5.99 = 8.01
You should doing this step by step, instead of search online
Forward reaction is a reaction in which products are produced from reactants and it goes from left to right in a reversible reaction.
For example, if the focus is on respiration, the forward reaction is written as
C6H12O6 + 6O2 ---> 6CO2 + 6H2O
If the focus is on photosynthesis, the forward reaction is written as
6CO2 + 6H2O ---> C6H12O6 + 6O2
