The formula for Keq for the first chemical reaction with
given Keq is:
<span>Keq 1 = [ HI ]^2 / [ H2 ] [ I2 ]</span>
<span>While the formula for Keq for the 2nd is:</span>
<span>Keq 2 = [ HI ] / [
H2 ]^(1/2) [ I2 ]^(1/2)</span>
We can see that the coefficients in the reaction are
equal to the exponents in the equilibrium equation. Therefore if we divide the
whole reaction by 2, then that means we have to take the square root of the
equilibrium equation. Or in this case,
Keq 2 = sqrt (Keq 1)
Keq 2 = sqrt (794)
<span>Keq 2
= 28.19</span>
C. carbon is the correct answer
Answer:
B.
Explanation:
Si is an element.
A compound is 2 different elements combined. H2O and NaCl fit this requirement, so they are compounds. They cannot be elements because they are not single elements like Si.
Answer:
C₆H₁₂O₆ and O₂ are reactant.
CO₂ and H₂O are products.
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Explanation:
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration.
Steps involve in anaerobic respiration are:
Glycolysis
Glycolysis is the first step of both aerobic and anaerobic respiration. It involve the breakdown of one glucose molecule into pyruvate and 2ATP.
Fermentation
The second step of anaerobic respiration is fermentation. It involve the fermentation of pyruvate into lactic acid or alcohol depending upon the organism in which it is taking place. There is no ATP produced, however carbon dioxide is released in this step.
