Since the volume is directly proportional to temperature, then the answer to your question is pretty obvious. If the volume of the gas increases, then it is very likely that the cause of it was due to an increase in the temperature.
I hope I was able to help you with your question. Let me know if you have further questionings. :)
<span>Carbon dioxide is one of the important factor in photosynthesis. It helps photosynthesis to take place and it will increase its rate provided the Oxygen supply level at night remains constant.It would probably keep increasing up to 100 percent assuming the light was on. The plant probably needs O2 at night. They generally don't make greenhouses more than about 1000 ppm because the improvement isn't worth the cost of pumping in all that extra CO2. The amount of light that the plant absorbs limits the benefit so it won't increase in proportion to the amount of CO2 past a certain point. It wouldn't be much improvement past about 5000 ppm from what I have heard before.</span>
Gypsum has the same hardness as a fingernail
Answer is: C. the concentration the products and reactants is constant.
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time.
Reaction rates of the forward and backward reactions are equal and there are no changes in the concentrations of the reactants and products.
