Which of the following reagents should be used to convert to Question 26 options: A) H2, Lindlar's catalyst B) Na, liquid NH3 C)
diamong [38]

Answer: The question is is not complete...here is the complete question.

Which of the following reagents should be used to convert 3-Hexyne to E-3-hexene

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.

Liquid butane, C4H10, is stored in cylinders to be used
Ganezh [65]

Answer:

  • <u>13.0kJ</u>

Explanation:

The<em> heat</em> to <em>vaporize</em> a l<em>iquid</em> is equal to the amount of liquid in moles multiplied by the specific <em>heat of vaporiztion</em> per mole.

First, calculate the number of moles in 35.5g of <em>butane</em>.

  • Molar mass of butane: 58.124 g/mol

  • Number of moles = mass in grams/molar mass

  • Number of moles = 35.5g / 58.124g/mol = 0.6107632mol

Now, calculate the heat to vaporize that amount of <em>liquid butane</em>:

  • Heat = number of moles × specific heat of vaporization

  • Heat = 0.6107632mol × 21.3kJ/mol = 13.0 kJ

The answer must be reported with 3 significant figures.

An ionic compound is composed of the following elements:
Amiraneli [1.4K]

Answer: N3 H12 P O3

Explanation:

From the question :

N = 31.57% H = 9.10% P = 23.27%

O= 36.06%

Divide each of the element by their respective relative atomic masses.

N = 31.57 / 14 = 2.26

H = 9.10/ 1 = 9.10

P = 23.27 / 31= 0.750

O =36.06 / 16 = 2.25

Divide each answer by the lowest of them all, we then have:

N = 2.26/ 0.750 = Approx = 3

H = 9.10 / 0.750 = Approx = 12

P = 0.750/ 0.750= 1

O = 2.25 / 0.750 = Approx = 3

The empiral formula is

N3 H12 P O3
