Answer:
b, its a polymer that translates genetic information.
Answer:
Magnesium oxide is a simple basic oxide, because it contains oxide ions. It reacts with water to form magnesium hydroxide which is a base.
Answer:1.
Explanation: This reaction is catalyzes by pyruvate dehydrogenase. Pyruvate being the end product of glycolysis has many fates after glycolysis,one of which is to enter the TCA(Tricarboxylic acid cycle) cycle. It is first converted to actetate by the action of pyruvate dehydrogenase. This enzyme converts pyruvate to acetate releasing CO2 and NADH because this oxidative decarboxylation of pyruvate is coupled with reduction of NAD+ which can feed into the electron transport chain.
A cleaning solution with an OH⁻ concentration of 2.5 × 10⁻⁴ mol/L, has a pH of 10.4 and is basic (options b and c).
<h3>How can we determine the acidity or basicity of a solution?</h3>
- If pH < 7, the solution is acid.
- If pH = 7, the solution is neutral.
- If pH > 7, the solution is basic.
- Step 1. Calculate the pOH of the solution.
The hydroxide ion concentration is 2.5 × 10⁻⁴ mol/L.
pOH = -log [OH⁻] = log (2.5 × 10⁻⁴) = 3.6
- Step 2. Calculate the pH of the solution.
We will use the following expression.
pH + pOH = 14
pH = 14 - pOH = 14 - 3.6 = 10.4
Since pH > 7, the solution is basic.
A cleaning solution with an OH⁻ concentration of 2.5 × 10⁻⁴ mol/L, has a pH of 10.4 and is basic (options b and c).
