Consider the following reaction at equilibrium: C(s)+H2O(g)⇌CO(g)+H2(g) Predict whether the reaction will shift left, shift righ

vazorg [7]

'Answer:

a) C is added to the reaction mixture. "shift right"

b) H₂O is condensed and removed from the reaction mixture. "shift left"

c) CO is added to the reaction mixture. "shift left"

d) H₂ is removed from the reaction mixture. "shift right"

Explanation:

Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.

a) C is added to the reaction mixture:

Adding C(s) will increase the concentration of the reactants side, so the reaction will be shifted to the right side to suppress the increase in the concentration of C by addition.

So, the reaction shift right.

b) H₂O is condensed and removed from the reaction mixture:

Removing H₂O will decrease the concentration of the reactants side, so the reaction will be shifted to the left side to suppress the decrease in the concentration of H₂O by removal.

So, the reaction shift left.

c) CO is added to the reaction mixture:

Adding CO will increase the concentration of the products side, so the reaction will be shifted to the left side to suppress the increase in the concentration of CO by addition.

So, the reaction shift left.

d) H₂ is removed from the reaction mixture:

Removing H₂ will decrease the concentration of the products side, so the reaction will be shifted to the right side to suppress the increase in the concentration of H₂ by removal.

So, the reaction shift right.

The polyatomic nitrate ion (NO3−) is present in both the products and the reactants of the chemical equation shown below.

Diano4ka-milaya [45]

Answer:

There is one nitrate ion in the products, and two in the reactants of this equation.

Explanation:

1: We know a nitrate ion has the formula $NO_{3}^{-$ , so we just need to count how many of them are on each side of the equation.

2: To find how many are in the reactants of the equation, you look at the left hand side (before the arrow). You can see the section $(NO_{3} )_{2}$ , which shows that there are two nitrate ions in the reactant side (as seen by the little 2).

3: To find how many are on the products side, you do the same thing - this time there is only one $NO_{3}^{-$ in the lithium nitrate.

So, there is one nitrate ion in the products, and two in the reactants of this equation.

A photon has an energy of 2.78 x 1032 J. What is its wavelength?

8090 [49]

Answer:

7.14 × 10^(-58) m

Explanation:

We are given;

Energy; E = 2.78 x 10^(32) J

Formula to find this energy is;

E = hc/λ

Where;

E is energy

h is Planck's constant with a constant value of 6.62 × 10^(-34) J/s

c is speed of light with a constant value of 3 × 10^(8) m/s

λ is wavelength

Making λ the subject, we have;

λ = hc/E

λ = (6.62 × 10^(-34) × 3 × 10^(8))/(2.78 x 10^(32))

λ = 7.14 × 10^(-58) m
