The general formula for an aldehyde is: b) rcho

An aldehyde in chemistry is an organic compound that contains the following functional group: RCHO in which the carbon atom is attached with a double bond with the oxygen atom and with a single bond with the hydrogen atom.

The aldehyde compounds are very used in the manufacture of solvents, perfumes and resins

The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.

What is the mass of 0.015 moles of NaOH?

JulsSmile [24]

Answer:

Mass = 0.6 g

Explanation:

Given data:

Moles of NaOH = 0.015 mol

Mass of NaOH = ?

Solution:

Number of moles = mass/ molar mass

by rearranging this formula,

Mass = number of moles × molar mass

Molar mass of NaOH is 40 g/mol

by putting values,

Mass = 0.015 mol × 40 g/mol

Mass = 0.6 g

What does weight measure?

Pavel [41]

The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton. For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, and about one-sixth as much on the Moon.

Write the balanced equation. Then calculate the volume of 0.65 M HCl required to completely neutralize 400.0 ml of 0.88 M KOH.

Misha Larkins [42]

Hello!

The balanced equation for the neutralization of KOH is the following:

HCl(aq) + KOH(aq) → KCl(aq) + H₂O(l)

To calculate the volume of HCl required, we can apply the following equation:

$moles HCl = moles KOH \\ \\ cHCl*vHCl=cKOH*vKOH \\ \\ vHCl= \frac{cKOH*vKOH}{cHCl}= \frac{400 mL*0,88M}{0,65M}= 541,54mL$

So, the required volume of HCl is 541,54 mL

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.
