Answer:

A. 68°F

B. 293K

Explanation:

The temperature (celsius) = 20.0°C

A. Conversion of the temperature in celsius to fahrenheit.

This is illustrated below:

°F = 9C/5 + 32

C = 20°C

°F = 9C/5 + 32

°F = 9x20/5 + 32

°F = 36 + 32

°F = 68°F

B. Temperature (Kelvin) = temperature (celsius) + 273

Temperature (celsius) = 20°C

Temperature (Kelvin) = 20°C + 273

Temperature (Kelvin) = 293K

Can any of you guys help me with this. Can y’all give me some facts about nucleus protons netrons and electrons :)
Mumz [18]

Answer:

the nucleus is the center of the atom, made up of protons and neutrons, without the nucleus you'd just have a bunch of electrons floating around; the nucleus is positively charged

protons are the positively charged particles that sit within the nucleus

neutrons are particles of no charge that sit within the nucleus, and because they have no charge, they do not cancel out the positive charge of the protons, making the nucleus positive

electrons are negatively charged particles that float around the nucleus in an area known as the electron cloud, they orbit around the nucleus because they are attracted to the positive charge of the nucleus (caused by the protons), with charges, opposites attract

Each of the following names is wrong. Draw structures based on them, and correct the names:(b) 1,1,1-trimethylheptane
devlian [24]

The correct IUPAC name of 1,1,1-trimethylheptane is 2,2-dimethyloctane.

<h3>IUPAC NAME:</h3>

It is systematic way of nomenclature of organic compounds.

It is based on the position of functional groups, preference of the functional group, long or short chain of carbon, preference of double bond, single and triple bond, branching of carbon chain, etc.

The given compound is 1,1,1-trimethylheptane.

The given name is wrong according to IUPAC name because the numbering of carbon atom should be done in that way in which the carbon atom chain is largest.

Here, in this case the numbering is done from right side. Thus the largest carbon chain have 8 carbon atom.

If the numbering is done according to the question, number of carbon atom in straight chain is 7.

Thus, we concluded that the Correct IUPAC name of 1,1,1-trimethylheptane is 2,2-dimethyloctane.
