True or False. Single covalent bonds are stronger than triple covalent bonds

Chemistry
1 answer:
yuradex [85]3 years ago
6 0

Answer:

False

Explanation:

Triple covalent bonds are much more stronger than single covalent bonds. In single bond, 2 electrons are shared, in double bond four electrons are shared and in triple bond six electrons are shared. Thus, triple bond is difficult to break since it is the strongest bond. Between the two atoms, stronger the bond, more stable the molecule. Thus, triple bond is more stable.

Calculate (a) the number of moles of hydrogen required to react with 0.0969 moles of nitrogen, and (b) the number of moles of am
Bumek [7]

Answer:

The answer to your question is:

Explanation:

Data

moles H=?

moles of N = 0.0969

moles of NH₃=?

                            N₂ (g)  + 3 H₂ (g)  ⇒   2NH₃ (g)

Process

1.- Set a rule of three to calculate the moles of hydrogen

                         1 mol of nitrogen  -------------   3 moles of hydrogen

                         0.0969 moles of N ----------     x

                         x = (0.0969 x 3) / 1

                         x = 0.2907 moles of hydrogen          

2.- Set a rule of three to calculate the moles of ammonia

                        1 mol of nitrogen --------------  2 moles of ammonia

                        0.0969 mol of N --------------   x

                        x = (0.0969 x 2) / 1

                        x = 0.1938 moles of ammonia

Consider the following reaction mechanism: Step 1: (CH3)3AuPH3 ↔ (CH3)3Au + PH3 (fast) Step 2: (CH3)3Au → C2H6 + (CH3)Au (slow)
netineya [11]

Answer: The balanced equation for overall reaction is:

(CH3)3AuPH3 ----> C2H6 + (CH3)AuPH3

Explanation:

The reaction mechanism is given as follows:

Step 1: (CH3)3AuPH3 ↔ (CH3)3Au + PH3 (fast)

Step 2: (CH3)3Au → C2H6 + (CH3)Au (slow)

Step 3: (CH3)Au + PH3 → (CH3)AuPH3 (fast)

To balance this equation, firstly, we conduct proper atom count for each steps of the reaction mechanism.

It is important to note that for a reaction that involves several steps, the rate law is normally derived from the slow step ( which is step2 from the above mechanism).

Therefore, the balanced chemical equation for the overall reaction is:

(CH3)3AuPH3 ----> C2H6 + (CH3)AuPH3

kvv77 [185]

Answer:

The number of pioneer species get less as the area has more soil to support complex plants and the competition decreases the role of pioneer species.

Explanation:

Pioneer species like Lichens and Mosses inhabit an area after a major disturbance, such as a volcanic eruption. However, with time the number of pioneer species decreases.

The number of pioneer species get less as the area has more soil to support complex plants and the competition decreases the role of pioneer species.

PLEASE HELP :"( DUE NOW!!
Citrus2011 [14]

Answer:

The correct answer is  

[CH4][H2O]/[CO][H2]3

Option 3 is correct

Explanation:

Step 1: Data given

For the equation aA + bB ⇆ cC + dD

The equilibrium constant is [C]^c * [D]^d / [A]^a*[B]^b

Step 2: Calculate the equilibrium constant Kc

CO+3H2⇌CH4+H2O

Kc = [H2O][CH4] / [CO][H2]³

The correct answer is  

[CH4][H2O]/[CO][H2]3

Option 3 is correct
