An alkene adds hydrogen in the presence of a catalyst to give 3,4-dimethylhexane. Ozonolysis of the alkene followed by treatment
slamgirl [31]

The structure of alkene is given below in the image.

Alkenes are described as both branched or unbranched hydrocarbons that possess at least one carbon-carbon double bond (CC) and feature a popular system of CnH2n [1].

Alkanes are organic compounds that encompass single-bonded carbon and hydrogen atoms. The formulation for Alkanes is CnH2n+2, subdivided into 3 companies – chain alkanes, cycloalkanes, and branched alkanes.

The geometry around each carbon atom is based totally on a trigonal planar shape, due to the fact, that each carbon has three electrons around it. This must make the angle of each bond one hundred twenty.

QUESTION 21 The combustion of ammonia in the presence of excess oxygen yields NO 2 and H 2O: 4 NH 3 (g) 7 O 2 (g) 4 NO 2 (g) 6 H
Harrizon [31]

Answer:

The answer to your question is 47.44 g of Oxygen

Explanation:

Data

mass of Ammonia = 14.4 g

mass of Oxygen = ?

Balanced chemical reaction

                 4NH₃  +  7O₂  ⇒  4NO₂  +  6H₂O

Process

1.- Calculate the molar mass of Ammonia

NH₃ = 4[(1 x 14) + (3 x 1)] = 4[14 + 3] = 4[17] = 68 g

2.- Calculate the molar mass of Oxygen

O₂ = 7[16 x 2] = 7[32] = 224 g

3.- Use proportions to calculate the mass of Oxygen

                     68g of NH₃ --------------------- 224 g of O₂

                      14.4 g of NH₃ -----------------  x

                       x = (14.4 x 224) / 68

                       x = 3225.6/ 68

                       x = 47.44 g

In a solution the hydroxide ion concentration is 1 ✕ 10-12 M. What is the pH of the solution?
Deffense [45]

Answer:

pH = 2 and pOH = 12

Explanation:

Given [OH⁻] = 1 x 10⁻¹²M

pOH = -log[OH⁻] = -log(1 x 10⁻¹²) = - ( -12 ) = 12

pH + pOH = 14 => pH = 14 - pOH = 14 - 12 = 2
