A salt sample is placed into some water and nearly all of it dissolves without stirring or heating. the resulting solution is

1 answer:

7 0

The resulting solution is unsaturated.

An unsaturated solution is one in which the amount of solute can be increased. We know that the solution is unsaturated because there is no salt at the bottom of the solution and no means were required to increase the salt's solubility such as increasing temperature or stirring. Once the solution becomes saturated, additional salt will only deposit at the bottom unless changes in conditions are made.

What happens if you choose the wrong solvent while setting up your NMR experiment?

MissTica

Answer:

Please see the answer..hope its works

Explanation:

The NMR spectrometer will acquire data for the wrong chemical shift range and you will potentially have skewed data when opening spinworks-NMR spectrometer examines a specific 12 ppm range based on the expected solvent peak, and if a different solvent is used a different range may be examined

To explain further, If the user declares the wrong solvent, one of two things may happen. Firstly, the spectrometer may not be able to establish a deuterium lock and will report an error and not run the sample. Secondly, the spectrometer may be able to establish a lock despite the fact that the deuterium signal is off resonance. If the lock is established, the field strength will be set to a value appropriate to put the declared solvent signal on-resonance. When a proton NMR spectrum is collected, the chemical shift scale will be incorrect by an amount equal to the proton chemical shift difference between the true solvent and the declared solvent.

Answer:

Potassium

Explanation:

From the given riddle. Potassium is the right answer. This because on the periodic table, potassium has the smallest atomic number of any element in its period with the electronic configuration 1s2 2s2 2p6 3s2 3p6 4s1, it has the largest atomic radius within its group because the radius has no d-electron shell filled. Potassium is a soft metal but contains high reactivity.

In testing the effectiveness of an antacid compound, 20.0g of Hydrochloric Acid is mixed with 28.0g of Magnesium Hydroxide. Will

BartSMP [9]

Answer:

Base Mg(OH)2 does neutralise the acid and is 12g in excess.

Explanation:

2HCL +Mg(OH)2 -> MgCl2 + 2H20

2 * 36.458 g of HCL react with 58.319 g of Mg(OH)2 to neutralise it.

72.916 HCl reacts with 58.319 g of the base.

So 20 g HCl reacts with (58.319/72.916) * 20 = 16g.

There are 28 g of Mg(OH)2 so the base does neutralise all the acid.

The Mg(OH)2 is 28 - 16 = 12 g in excess.
