Answer:

In the case of the Hardwood floor vacuum, you have to use a vacuum cleaner to clean hardwood floors. If you use a hard-bristled broom, it can damage the exterior of Hardwood floors. On the other hand, the vacuum creates less airborne dust and doesn't damage the surface of hardwood floors.When done correctly, the vacuuming process can remove more soil from a floor than a dust mop or broom. ... “The vacuum sucks up and removes all the dust, even the fine dust. It removes all the soil.” Vacuums typically do a better job than mops at reaching dirt in cracks and corners

A 1.25 × 10-4 m solution of the anti-inflammatory drug naproxen has a ph = 4.2. the ka and pka of naproxen are ________ and ____

Mandarinka [93]

Naproxen is known to be a weak acid. In order to calculate its ka and pka, use the equation of getting the ph of weak acid which is ph= -1/2 log [(Ka)(Mwa)]. The Ka value is 3.18x10^-5. The pKa can be obtained through pKa = - log Ka. The pKa is 4.5.

Give the chemical formula and systematic name for aurous sulfide, which is named using the older nomenclature. spelling counts!

Bingel [31]

Aurous is a cation of gold. Gold takes the name "aurum" (Au) with atomic number of 79. In its purest form, the element is bright, slightly yellow, soft, ductile, and malleable. The charge of aurous is +1. Sulfide, on the other hand, has a charge of -2.

Hence, the chemical formula of the compound is Au₂S and its systematic name is gold (I) sulfide.

Draw an alkyl bromide with proper stereochemistry that can be used to synthesize the given alkene as the exclusive product via a

enot [183]

Answer:

See explanation below

Explanation:

You forgot to put the picture to do so. In this case, I manage to find one, and I hope is the one you are looking for. If not, then post it again and I'll gladly help you out again.

According to the picture with the answer, we have a cyclohexane with 4 methyl groups there. Two of them are facing towards the molecule with a darker bond. This means that the alkyl bromide, should have a bromine in one of the bonds, and in order to produce an E2 reaction, this bromine should be facing in the opposite direction of the methyl groups which are facing towards. This is because an E2 reaction occurs with the less steric hindrance in the molecule. If the bromine is in the same direction as the methyl group, it will cause a lot more of work to do a reaction, and therefore, an E2 reaction. I will promote instead a E1 or a sustitution product.

Therefore the alkyl bromide should be like the one in the picture 2.
