Coach is used to activate carboxylic acids. what type of compound is formed between coach and a carboxylic acid?
MrMuchimi

The  type of compound is formed between coach and a carboxylic acid alcohol + carboxylic acid → ester + water.

How carboxylic acids are formed?

A acid is produced after the acidic hydrolysis of esters and carboxylates are produced after the basic hydrolysis of an ester.

What are the functional group of alcohol and carboxylic acid?

Alcohols contain the hydroxyl functional group and may be primary, secondary, or tertiary. Ethers are compounds with an oxygen atom bonded to 2 alkyl groups. Aldehydes and ketones contain the carbonyl functional group

Can a compound be a acid and an alcohol?

Esters are represented by the formula RCOOR', where R and R' are hydrocarbon groups. The ester, which is compound derived from a carboxylic acid and an alcohol in which the OH of the acid is replaced by an OR group, looks somewhat sort of a n ether and also somewhat like a carboxylic acid.

If 6 moles of a compound produce 84 J of energy, what is the a<br> Hreaction in J/mol?
Vikki [24]

Answer:

14 J of heat

Explanation:

Recall that the enthalpy of reaction is defined as the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, if all reactants and products are in their standard states. Here we have the heat of formation of six moles of the substance and we are expected to use it to obtain the the heat of formation of one mole of the compound and we can do that by simple proportion as shown below;

If 6 moles of the compound produces 84J of heat

1 mole of the substance will produce 1×84/6 = 14 J of heat
