Consider the following reaction where Kc = 1.80×10-2 at 698 K:2 HI (g) H2 (g) + I2 (g)A reaction mixture was found to contain 0.
Iteru [2.4K]

Answer:

Answer for the given statements: (1) T , (2) F , (3) T , (4) F , (5) F

Explanation:

At the given interval, concentration of HI = \frac{0.304}{1}M=0.304M

Concentration of H_{2} = \frac{5.07\times 10^{-2}}{1}M=5.07\times 10^{-2}M

Concentration of I_{2} = \frac{4.57\times 10^{-2}}{1}M=4.57\times 10^{-2}M

Reaction quotient,Q_{c} , for this reaction = \frac{[H_{2}][I_{2}]}{[HI]^{2}}

species inside third bracket represents concentrations at the given interval.

So, Q_{c}=\frac{(5.07\times 10^{-2})\times (4.57\times 10^{-2})}{(0.304)^{2}}=2.51\times 10^{-2}

So, the reaction is not at equilibrium.

As Q_{c}> K_{c} therefore reaction must run in reverse direction to reduce Q_{c} and make it equal to K_{c}. That means HI(g) must be produced and H_{2} must be consumed.

Explained how natural factors have changed the surface and atmosphere of the Earth over time?
Ne4ueva [31]

Answer:

The earth's climate is influenced and changed through natural causes like volcanic eruptions, ocean currents, the Earth's orbital changes, solar variations and internal variability. is short-term cooling. Volcanic eruptions pump out clouds of dust and ash, which block out some sunlight.

Why was the measurement unit for metal content in Experiments 1 and 2 different? In Experiment 1:
olya-2409 [2.1K]

To identify why a metal measurement was different in the experiments look for the variable that was different in the experiment and analyze how this change affected the results.

<h3>What is an experiment?</h3>

An experiment is a procedure that aims at probing or discovering something. For example, you can test if a plant grows faster/slower by using an experiment.

<h3>What causes different results in similar experiments?</h3>

The most common cause for this situation is that one of the factors or variables is slightly different. For example, if I add 50mL of water to a plant rather than 20mL of water every day this might cause different results.

Based on this, if the metal content was different you should analyze if any of the factors changed in this experiment and find out how this change affected the general results.

Note: This question is incomplete because there is limited information about the experiment; due to this, I answered it based on general knowledge.
