Answer:
option c is correct
Explanation:
the addition of catalyst does not effect the position or equilibrium constant and increase the forward and backward reaction in equal rates so no effect would be observed
Answer:The answer is Rosalind Franklin
Explanation:It is the only option that would be correct because the last person had two people for Rosalind and James I think, but Rosalind is definitely the correct answer
The danger from radon gas would most likely be greatest in well-insulated homes. It is a toxic gas.
<h3>What is radon gas?</h3>
Radon is a naturally radioactive gas generated from different elements such as uranium or radium.
Radon is generated when these radioactive materials naturally decompose in the soils and/or rocks.
Radon is highly toxic and therefore this gas must be avoided to maintain healthy conditions in a home.

Answer: 0.174 g
Explanation:
First of all understand that charge on an atom like here 2+ will not vary molar mass. because ions are formed by loss or gain of electrons and electrons do not contribute to the mass of an atom or ion. so losing or gaining electron doesnt create any difference.
molar mass of Fe, i.e. mass of 1 mole of Fe is 56 g. So, mass of 1 mole of Fe2+ will also be 56 g.
given is 0.003109 moles of Fe2+,
Use maths,
1 mole of Fe2+ weighs 56 g
So, 0.003109 moles will weigh = (56 g / 1 mol ) x 0.003109 = 0.174 g.
Answer:
Option (2) At equilibrium, there is a much higher concentration of products than reactants.
Explanation:
The equilibrium constant for a reaction is simply the ratio of the concentration products raised to their mole ratio divided by the concentration of the reactants raised to their mole ratio.
If the equilibrium constant is close to 1 or 1, it means the concentration of the reactants and products are almost the same. But if the equilibrium constant is large as in the case of the question given above, it means that at equilibrium, the concentration of the products are higher than that of the reactants.
