A substance and a solution have both uniform composition throughout. A substance is a matter that is uniform in composition and can be an element or compound. A solution is another name for homogeneous which is a mixture. The difference of substances and solution, a substance has a definite composition and a solution has a variable composition. It is also uniform in composition, but a solution is made by combining two or more substances.
I believe the correct answer from the choices listed above is option A. The E+ of the cell would be 2.47 V. E of the cell is given by the formula E(cathode) - E(anode) . <span>So in this case the first half cell reaction is the reaction that takes place in the cathode and the second one takes place in the anode.</span>
Answer:
The compounds in the samples will leach into the pool of developing solvent resulting in poor resolution.
Explanation:
The aim of thin layer chromatography is the separation of a mixture. Usually, the stationary phase is spotted with the mixture. A mark is made with a pencil at the point to be spotted.
It is necessary to note that the solvent must be below the spot where the mixture is. This is because, if the solvent is above the spot of the mixture to be separated, the components of the mixture will dissolve away in the solvent resolution in poor separation. This is exactly what will happen when the sample is spotted at 1.0 cm above the bottom when the solvent is 1.2 cm above the bottom.
Answer:
There should be about 3136.9mg of Na in a 12.5oz bag of cheese curls.when rounding if not rounded it would be 3126.04082143mg
Explanation:
12.5oz=354.4g
354.4/28=12.7
12.7*247=3136.9
