Answer:
Acidic conditions
Explanation:
From the equations, it is clear that addition of acid favours the precipitation of calcium oxalate. As acid is added, the equilibrium position continues to shift to the far right, favouring the complete dissociation of the oxalic acid. This decreases the pH of the solution by increasing oxonium ion concentration.
Similarly, as the oxalate ion concentration increases, the precipitation of the calcium oxalate is favoured at low pH. Hence the answer.
The answer is B.
Step By Step Explanation:
Answer: 100C of heat is needed.
Explanation: That is the heating point of water
Answer:
1
Explanation:
A <em>simple cubic unit cell</em> means that there is 1 atom of Hg in each of the eight corners of a cube. Each of these atoms "contributes" one-eight (1/8) of its mass to form one single unit. With 8 atoms each contributing 1/8, the unit cell has a total of one atom of Hg.
Answer:
NAP+ accepts hydrogen and releases oxygen.
That's just from my hunch
Explanation:
The light dependent reactions <em>release</em><em> </em><em>oxygen</em><em> </em>from the hydrolysis of water as a by product.
