Describe a polyhydroxyl alcohol.

Answers

To know that a certain compound is classified as an alcohol is through it molecular equation. Alcohols have at least 1 -OH or hydroxyl attachment. When we say polyhydroxyl that means there is 2 or more hydroxyl group in the structure of an alcohol. Ethylene glycol is an example.

A polyhydroxyl alcohol is an alcohol that has two OH molecules attached. A regular alcohol has only one.

NaHCO3 (s) + HC2H3O2 (aq) = NaC2H3O2 (aq) + H2O (I) + CO2 (g)Using the above formula, if I used 0.100L of 0.83 M HC2H3O2 (aq) (0.83 mol per 1 L of solution), how much carbon dioxide would be produced?

Answers

Moles=volume*concentration
=0.1*.83
=.083 Moles of HC2H3O2
Mole ratio between HC2H3O2 and CO2 is 1:1
This means .083 Moles of CO2

Mass =Moles*Rfm of CO2
=.083*(12+16+16)
=3.7grams

Final answer:

By utilizing stoichiometry, we can determine that the given volume and molarity of acetic acid (HC2H3O2) would produce approximately 3.65 grams of carbon dioxide (CO2). The calculation involves determining the moles of HC2H3O2 used, which equals the moles of CO2 produced, and converting that to grams using the molar mass of CO2.

Explanation:

The amount of carbon dioxide produced can be determined through stoichiometry, using the provided balanced chemical equation and molarity (M) of the acetic acid HC2H3O2. According to the balanced chemical equation, one mole of NaHCO3 reacts with one mole of HC2H3O2 to produce one mole of CO2. In other words, the moles of HC2H3O2 used equals the moles of CO2 produced.

First, calculate the moles of HC2H3O2 by multiplying the given volume (0.100 L) by its molarity (0.83 mol/L): 0.100L x 0.83 mol/L = 0.083 mol.

So, according to the stoichiometric ratio, 0.083 mol of HC2H3O2 would produce 0.083 mol of CO2. If you want your answer in grams, note that the molar mass of CO2 is approximately 44.01 g/mol. Multiply the moles of CO2 by its molar mass: 0.083 mol x 44.01 g/mol = 3.65g.

So, the amount of CO2 produced would be 3.65 grams.

Which particle diagram represents a sample of matter that can not be broken down by chemical means?

Answers

Answer;

Considering the attached image;

The correct answer is D.

Explanation;

-An element is a substance that can not be broken down into simpler substances by ordinary chemical means. Example, iron, gold, hydrogen , carbon, oxygen , etc.

-Elements are made of atoms. An atom is the smallest particle of an element that can take part in a chemical reaction. Atoms of different elements are different. Atoms of one element are basically alike.

In the picture below that I attached, the answer is D.

In the diagram, there are only one type of element depicted.
