Wewaii [24]3 years ago
3 0

Answer:

the acceleration is 3 k/h/s

Explanation:

The formula for acceleration is Δv/t, so change in velocity divided by time.

The original velocity is 15 kph, and the final velocity is 30 kph. Therefore, the change in velocity is 15 kph. 15/5=3 k/h/s

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.

How many moles are in 3.45 g of Na2O?Round your answer to three significant
Neporo4naja [7]

Answer: There are 0.056 moles present in 3.45 g of Na_{2}O.

Explanation:

Given : Mass = 3.45 g

Moles is the mass of substance divided by its molar mass.

Hence, moles of Na_{2}O (molar mass = 61.98 g/mol) is as follows.

Moles = \frac{mass}{molar mass}\\= \frac{3.45 g}{61.98 g/mol}\\= 0.056 mol

Thus, we can conclude that there are 0.056 moles present in 3.45 g of Na_{2}O.
