Answer:
3rd option. 1–butanamine
Explanation:
To name the compound above, the following must be observed:
1. Locate the functional group in the chain. In this case the functional group is amine.
2. Locate the longest continuous carbon chain. This gives the parent name of the compound. In this case, the longest chain has 4 carbon i.e butane.
3. Since the functional group is amine, the parent name becomes butanamine i.e replacing the –e at the end in butane with –amine
4. Indicate the position of the functional group in the chain. In this case the functional group is at carbon 1
5. Name the compound by putting the above together.
The name of the compound is:
1–butanamine or butan–1–amine
The answer is calcium chloride.
Answer:
28.38 ml of H202
Explanation:
<u><em>Given data:</em></u>
the concentration of H2O2 = 3.0 % v/v (3ml / 100 ml of solution of H2O2
the volume of the bottle : 946 ml
<em><u>Formula: </u></em>
Percent by volume: volume of solute/volume of solution×100%
<em><u>Solution:</u></em>
= (3.0 mL/ 100 ml) × 946 mL
= 0.03 x 946 ml
= 28.38ml of H202
