List 2 ways strong and weak acids differ.
Soloha48 [4]
A strong acid is an acid that ionizes completely in an aqueous solution. A strong acid will always loose a proton (A H+) when dissolved in H2O. In other words, a strong acid is always on its toes and quite efficient in giving off protons. A weak acid is one that ionizes partially in a solution.There you go, I hope this helped.

267 moles of NADH are produced by the Citric Acid Cycle (CAC). How many moles of glucose needed to be broken down during glycoly
leva [86]

Answer:

45 moles

Explanation:

From glycolysis, 1 mole of glucose gives 2 moles of pyruvate which undergoes citric acid cycle.

1 mole of pyruvate undergoes citric acid cycle (After conversion to acetyl-CoA) gives 3 moles of NADH.

Also,

2 moles of pyruvate undergoes citric acid cycle (After conversion to acetyl-CoA) gives 6 moles of NADH.

Thus,

6 moles of NADH are produced from 2 moles of pyruvate or 1 mole of glucose.

1 mole of NADH is produced from 1/6 mole of glucose

267 moles of NADH are produced from \frac {1}{6}\times 267 moles of glucose.

<u>Thus, moles of glucose needed to be broken ≅ 45 moles</u>

What are the products of the chemical reaction between solutions of sodium bromide with a solution of silver nitrate?
iren2701 [21]

Answer : The products of the chemical reaction are, NaNO_3 and AgBr

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

When sodium bromide react with silver nitrate then it react to give sodium nitrate and silver bromide as a product.

The balanced chemical reaction will be:

NaBr+AgNO_3\rightarrow NaNO_3+AgBr

The given reaction is a double-displacement reaction in which the cation of two reactants molecule exchange their places to give two different products.

The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.

In the balanced chemical reaction,

NaBr and AgNO_3 are reactants.

NaNO_3 and AgBr are products.

Hence, the products of the chemical reaction are, NaNO_3 and AgBr
