Goryan [66]3 years ago

Answer:

Option B. The equilibrium of the reaction would shift to the right.

Explanation:

According to Le Chatelier's principle, when an external constrain such as change in concentration, temperature or pressure is imposed on a chemical system in equilibrium, the equilibrium position will shift in order to neutralize the effect.

Now, let us answer the question above.

From the question given above, the equation is:

A + B <===> C + D

Increasing the concentration of A will shift the equilibrium position to the right.

This is true because increasing the concentration of A means having more reactants in the system. So the reactants react to produce more product thereby shifting the equilibrium position to the right.

What is S for the reaction N2(g) +O2(g) 2NO? Use G = 173.3 kJ at 303.0 K and H = 180.7 kJ. Use G = H – TS.
Rashid [163]

Given information :

G = 173.3 KJ

H = 180.7 KJ

T = 303.0 K

S = unknown (?)

By using the given formula : G = H - TS , we can calculate the value of 'S'

On rearranging the formula we get : S = \frac{H-G}{T}

Plug in the value of G , H and T in the above formula :

S = \frac{(180.7 KJ - 173.3KJ)}{303.0K}

S = 0.02442 \frac{KJ}{K}

Describes the difference between the formulas for nitrogen monoxide and nitrogen dioxide?
qwelly [4]

Answer:

nitrogen monoxide: NO

nitrogen dioxide: NO₂

Explanation:

Nitrogen monoxide is composed by 1 atom of O (prefix "mono-") and 1 atom of N. Nitrogen dioxide is composed by 2 atoms of O (prefix "di-") and 1 atom of N. As the oxigen atom in oxides has the valency -2 (it shares 2 electrons), the nitrogen has valency +2 in NO and +4 in NO₂.

Answer:

36365.4 Joules

Explanation:

The quantity of Heat Energy (Q) released on cooling a heated substance depends on its Mass (M), specific heat capacity (C), and change in temperature (Φ)

Thus, Q = MCΦ

Since, M = 45.4 g

C = 3.56 J/g°C,

Φ = 250°C - 25°C = 225°C

Q = 45.4g x 3.56J/g°C x 225°C

Q= 36365.4 Joules

Thus, 36365.4 Joules of heat energy is released when the lithium is cooled.
