When both –NH2 and –COOH replace hydrogen atoms on the same carbon atom, a(n) ____ is formed. a. amine c. carboxylic acid b. ami
Mice21 [21]

-NH_{2} represents amine functional group and COOH represents carboxylic acid functional group. When these both functional groups are substituted onto a single carbon atom, then amino acid is formed.

The organic compound consists of -NH_{2} functional group and COOH functional group with a side chain is said to be an amino acid.

A: amine group is -NH_{2}.

C: carboxylic acid  group is COOH

B: amino acid represents -NH_{2} functional group and COOH functional group which are substituted onto a single carbon atom.

D: carbohydrate:  the general formula of carbohydrate is (CH_{2} O)_{x}.

Hence, amino acid is the correct answer.

Answer:

1. First

2. Third

3. Fourth

4.remain the same as

Explanation:

Given the reaction equation;

Rate= k[A] [B]^3

We can see that the order of reaction is first order with respect to reactant A and third order with respect to reactant B. This gives an overall fourth order reaction.

If the concentration of A is doubled and that of B is halved. The rate of reaction remains the same.
