Answer: 1.1 moles H2O

Explanation: It looks like the equation is already balanced for you, so the first step will be to convert 144.1 grams of HNO3 to moles. To do this find the molar mass, and use to to do your conversion.Using the numbers provided for mass, this is the equation:1(1.0) + 1(14) + 3(16) = 1 + 14 + 48 = 63 g/mol144.1 g HNO3 x 1 mol HNO3 = 2.287 mol HNO3 63 g HNO3Now that you know how many moles of HNO3 you're starting with, use the ratio of moles in the equation to find the moles of H2O produced. The coefficient of HNO3 is 8, and H2O is 42.287 mol HNO3 x 4 mol H2O = 1.144 mol H2O 8 mol HNO3

Determine the type of alcohol corresponding to each given description or name. 1-pentanol 3-ethyl-3-pentanol 2-hexanol An alcoho

pochemuha

Answer:

1). 1-pentanol - Primary

2). 3-ethyl-3-pentanol - Tertiary

3). 2-hexanol - Secondary

4). Alcohol with two other carbons attached to the carbon with the hydroxyl group - Secondary

5). Alcohol with one other carbon attached to the carbon with the hydroxyl group - Primary

6). Alcohol with three other carbons attached to the carbon with the hydroxyl group - Tertiary

Explanation:

The distinct types of alcohol have been matched with the categories above as per their descriptions provided. In chemistry, alcohols have been categorized into three different categories namely primary, secondary, and tertiary.

In the primary type, those alcohols are involved in which there is an association of hydroxyl group to a primary atom of carbon along with a minimum of two atoms of hydrogen. Example; ethanol.

In the secondary type, the alcohols have an association of carbon atoms to hydroxyl with a single atom of hydrogen and has a formula of '-CHROH.' Example: 2 - propanol.

In the tertiary alcohols, here the association is between the hydroxyl group with the carbon atom that is saturated and possessing 3 atoms of carbon associated with it. It has a formula of '-CR2OH.' Example: 3-ethyl-3-pentanol, -tert -butyl alcohol, etc.
