The answer is C. Assume specific heat to be 4.18 J/g/C
<u>Answer:</u> The percent change in volume will be 25 %
<u>Explanation:</u>
To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Percent change of volume =
Percent change of volume =
Hence, the percent change in volume will be 25 %
An ecosystem is a large community of living organisms (plants, animals and microbes) in a particular area. The living and physical components are linked together through nutrient cycles and energy flows. Basically where they live
<u>Answer:</u> The equilibrium concentration of water is 0.597 M
<u>Explanation:</u>
Equilibrium constant in terms of concentration is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For a general chemical reaction:
The expression for is written as:
The concentration of pure solids and pure liquids are taken as 1 in the expression.
For the given chemical reaction:
The expression of for above equation is:
We are given:
Putting values in above expression, we get:
Hence, the equilibrium concentration of water is 0.597 M
Answer:
<em>It is a chemical reaction in which the reactants form products and products react together to give reactants back. That means reversible reactions can go in both directions forward as well as backward direction.</em>
