<span>When cooking frozen cheese ravioli, you should use three quarts of water instead of one so that the raviolis have room to move around in the boiling water and so that while they are moving around, they will not stick to each other or the pan.</span>
Answer:
4.5× 104 + 1.7× 105. Firstly, we need to ensure that both exponents have the same value. Thus, we need to change the value of 1.7 x 105 to 17 x 104. If both already had the same exponential value, you can neglect this step. 4.5× 104+ 17 × 104. Now, we will take exponentials common and add the decimal values. (4.5+ 17) × 104 | 21.5 × 104. Similar steps are taken for the subtraction phase we just need to retrace our steps and find differences rather than sums. These lessons and worksheets show you how to perform sums and differences with values that are in scientific notation.

Answer:
A. c. Keq=[H2]^2[S2]/[H2S]^2
B. b. Keq=[COCl2]/[CO][Cl2]
Explanation:
Hello,
In this case, considering the law of mass action which states that the equilibrium expression is written in terms of the concentration of products divided by the concentration of reactants considering the stoichiometric coefficients as powers we obtain:
A. For the reaction:
The equilibrium expression is:
![Keq=\frac{[H_2]^2[S_2]}{[H_2S]^2}](https://tex.z-dn.net/?f=Keq%3D%5Cfrac%7B%5BH_2%5D%5E2%5BS_2%5D%7D%7B%5BH_2S%5D%5E2%7D)
Therefore, answer is c. Keq=[H2]^2[S2]/[H2S]^2.
B. For the reaction:
The equilibrium expression is:
![Keq=\frac{[COCl_2]}{[CO][Cl_2]}](https://tex.z-dn.net/?f=Keq%3D%5Cfrac%7B%5BCOCl_2%5D%7D%7B%5BCO%5D%5BCl_2%5D%7D)
Therefore, answer is b. Keq=[COCl2]/[CO][Cl2].
