Preparation the buffer solution: initial pH of buffer solution: ____ Titration of a weak acid with a strong base: initial pH of

Nikolay [14]

Answer:

pH of buffer solution is 7.0

Initial pH of Weak acid is 3.27

Final pH of weak acid is 3.07

Amount of NaOH added is 1ml

Explanation:

Titration is a process in which acid and base are introduced together until a neutral solution is achieved whose pH value is near to buffer solution which is 7.0, the pH value for acid is below 7 while pH value for base is above 7.

For the reaction, calculate how many moles of the product form when 0.012 mol of O2 completely reacts. Assume that there is more

Westkost [7]

Answer:

0.008

Explanation:

From the balanced equation, 3 moles of oxygen gas produced 2 moles of the product. Then, 0.012 moles of oxygen gas will produces 0.012 x 2/3 = 0.008

A typical hydrogen peroxide solution from a drug store is labeled as 3.0% hydrogen peroxide. What is the other 97% of this compo

GarryVolchara [31]

Answer: Water

Explanation:

Chemically speaking, a solution has two components: solute and solvent.

The solute is that substance (usually solid, but it can also be liquid or gas) that dissolves in a liquid substance and its proportion in the resulting solution is usually less than the solvent.

The solvent is the substance used to dissolve the solute, and generally its proportion in the resulting solution is greater. Being the most common used solvent water.

This means that in a solution there is usually more solvent than solute.

So, in the case of the hydrogen peroxide solution, since the proportion is $3\%$ to $97\%$ , the hydrogen peroxide is the solute and water is the solvent.

Jane made this picture to represent a chemical reaction: Two circles, one white and the other gray are shown on the left. A smal

It represents a decomposition reaction because one reactant breaks apart and forms two products.

Explanation:

The type of chemical reaction depicted by Jane represents a decomposition reaction because on reactant breaks apart and forms two products.

In this reaction XY breaks apart to form X and Y. This is a decomposition reaction.

XY → X + Y

Decomposition or cracking is the formation of two or more products from a single reactant.
The break down of a compound into individual atoms or molecules falls into this category.
The extreme instability of a compound drives such a reaction.
The products is usually stable or it can dissociate further till it is stable.
