Predict the effect of the following changes in the reaction CO (g) + 2 H2 (g) <-> CH3OH (g) + energy.
Sophie [7]

Explanation:

  Equation of reaction:

             CO   + 2H₂    ⇒   CH₃OH   +   energy

a.  An increase in pressure:

A change in pressure affects only equilibrium involving a gas or gases. Le Chatelier's principle can be used to predict the direction of displacement.

An increase in pressure on an equilibrium system will shift the position of equilibrium to the side having smaller volume and vice-versa

       CO   + 2H₂    ⇒   CH₃OH   +   energy

          3 moles                  1 moles

An increase in pressure will favor the forward reaction to be favored.

b. Addition of H₂:

An in concentration of a specie favors the direction that uses up that specie and lowers its concentration.

Addition of hydrogen gas increases the concentration of amount of substances reacting.

To annul the effect of the reactant, more the product is given. The equilibrium shifts in the forward direction.

Prform the following operation and express the answer in scientific notation 6.0 x 10^3-2.310^3
Marrrta [24]

The value 6.0 x 10^3- 2.3 × 10^3 in scientific notation is 3.7 × 10^3.

<h3> What is scientific notation?</h3>

Scientific notation is a way to write very large or very small numbers so that they are easier to read and work with.

You express a number as the product of a number greater than or equal to 1 but less than 10 and an integral power of 10 .

<h3>Why it is used? </h3>

There are two reasons to use scientific notation.

  • The first is to reveal honest uncertainty in experimental measurements.
  • The second is to express very large or very small numbers so they are easier to read.

Given,

= 6.0 x 10^3- 2.3 × 10^3

= (6.0 - 2.3) × 10^3

= 3.7 × 10^3

Thus, we find that the value 6.0 x 10^3- 2.3 × 10^3 in scientific notation is 3.7 × 10^3.

The magnitude of an earthquake, measured on the Richter Scale, is M log1o T where / is the amplitude registered on a seismograph
just olya [345]

<u>Answer:</u> The magnitude rating for an earthquake causing an amplitude 10,000,000 times I_o is 7.

<u>Explanation:</u>

Richter scale is defined as the scale which expresses the magnitude of earthquake on the basis of the seismograph oscillations.

The equation used to measure the magnitude of an earthquake on Richter scale is:

M=log_{10}\frac{I}{I_o}

where

I = amplitude registered on seismograph 100 km away from seismic center = 10,000,000I_o

I_o = small amplitude

Putting values in above equation, we get:

M=\log_{10}(\frac{10000000I_o}{I_o})\\\\M=7

Hence, the magnitude rating for an earthquake causing an amplitude 10,000,000 times I_o is 7.
