myrzilka [38]

Answer:

0.11 nm

Explanation:

1.1 x 10-10 m

The goal is to convert the atomic radius from meters (m) to nanometres (nm). We do this by multiplying the value by 10^9.

This is given as;

1.1 * 10^{-10}  * 10^{9}\\1.1 * 10^{-10 + 9}\\1.1 * 10^{-1}\\0.11

Option B.

Na, liquid NH3.

Explanation:

3-Hexyne to E-3-hexene can be converted with by using the reagent of Na, NH3 (birch reduction) and this can be done by hdrogenation of H2.

The reagents NaNH3 convert 3-Hexyne to E-3-hexene because it is a reducing agents that convert or has the ability to reduce alkynes to trans alkenes.

3 Hexyne is an alkynes and it is converted to E- 3 hexene Na and NH3.

Given the reaction represented by the balanced equation:
user100 [1]

Answer:

mass of CHF_3 = 1/3 \times 9.47 \times 70 =220.97g

Explanation:

CH_4(g)+3F_2(g)->3HF(g)+CHF_3

As given in the question that methane(CH_4) is taken excess amount

mass of CHF_3 depend only on mass of fluorine

mass of F_2 =180 g

mole of F_2=\frac{180}{19} =9.47

3 mole of F_2 gives 1 mole of CHF_3

so 1 mole will give \frac{1}{3} mole of CHF_3

therefore,

9.47 mole of F_2 will give \frac{1}{3}  \times 9.47 mole of CHF_3

mass of CHF_3 = 1/3 \times 9.47 \times 70 =220.97g
