In the following equation, ______ is being oxidized and ______ is being reduced.
Mashcka [7]

oxidation \: number \: of \: oxygen =  \\ before \: rxn =  - 2 \\ after \: rxn =  - 2

oxidation \: number \: of \: hydrogen = \\ before \: rxn =  + 1 \\ after \: rxn =  \\ 2x - 2 = 0 \\ x =  + 1

oxidation \: number \: of \: carbon =  \\ before \: rxn =  \\ x  - 6 =  - 2 \\ x = 4 \\ after \: rxn =  \\ x - 4 = 0 \\ x = 4

<h2>Option A</h2>

oxidation \: numbers \: remain \: constant \\ so \: none \:a re \: undergoing \: oxidation \: \\ nor \: reduction \:

What causes gas particles to collide with the walls of their containers?
blondinia [14]

Answer:

Kinetic energy

Explanation:

The kinetic energy of a particle is directly proportional to the temperature of it. An increase in temperature increases the speed in which the molecules move, causing t[he particles to collide with the walls of their containers.

slamgirl [31]

Answer:

Combination or synthesis

Explanation:

The reaction given below:

             C    +  O₂    →  CO₂  

The reaction above is termed a synthesis or combination reaction because two substances are combining to give a product.

  • A synthesis reaction involves the formation of a single product from two or more reactants.
  • The driving force for such reaction is the large and negative heat of formation of the product.

Kp for the following reaction is 0.16 at 25 degree C. 2 NOBr(g) 2 NO(g) Br_2(g) The enthalpy change for the reaction at standard
finlep [7]

Answer:

Explanation:

Given that:

2 NOBr_{(g)} \iff 2 NO_{(g)} + Br_{2(g)}

From above:

K_p = 0.16 = \dfrac{(P_{NO})^2 (P_{Br})}{(P_{NOBr})^2}

To predict the effect of the addition of Br₂(g);

The addition of Br₂(g) will favor the equilibrium to shift to the left i.e. formation of NOBr

The removal of some NOBr will cause the equilibrium position to shift to the left side. This is because concentration on the left side is decreased and the concentration on the right side will be increased. Thus, the equilibrium will shift towards where the concentration is reduced which is the left side.
