Answer:

9-10 ppm.

0.2-0.4 ppm.

Explanation:

The proton on the aldehyde group will appear at approximately 9-10 ppm whereas the methylene peak on the alcohol is the only peak 0.2-0.4 ppm for either compound. Aldehydes and aromatics are quite distinctive in the Nuclear magnetic resonance (NMR). Aldehydes show up from 9-10 ppm, usually as a small singlet; aromatic protons show up from 6.5-8.5 ppm. NMR spectroscopy is the use of NMR to study the physical, chemical, and biological properties of matter.

Z is a covalent substance. In an experiment, a sample of pure solid Z was continually heated for 11 minutes
11111nata11111 [884]

When a pure solid Z sample it a covalent compound is heated continually for 11 minutes it will undergo disintegration leaving the bonds intact.

<h3>What is a covalent compound?</h3>

A covalent compound is a compound that is made up of molecules which share one or more pairs of valence electrons and are bonded together by a covalent bond.

One of the major factors that affect compounds with covalent bonds is temperature.

The increase in temperature during heating leads to the separation of the atoms from each other but leaving the bonds intact.

What is the average mass of a single silicon atom in grams?
torisob [31]

1 mol of Silicon = 28.0855 g (in average)

then

1 mol = 6.022*10^23 atoms

then

28.0855/(6.022*10^23) g/atom

4.66381*10^-23 g per atom

A balloon with volume of 2.0l is filled with gas at 3 atmosphere. If the pressure were reduced to 0.5 atmosphere without the cha
solong [7]
Answer: 12L

Explanation:

To find the correct volume of the balloon, we can use the mathematical representation of Boyle’s law which states that a gas’s volume is inversely proportional to its pressure (as one increases the other decreases).

The equation for it is P1 * V1 = P2 * V2 where P1 and V1 represent the initial pressure and volume of the gas and P2 and V2 represent its changed temperature and volume.

In this case, the initial pressure of the gas inside the balloon is 3atm while its initial volume is 2.0L. Its pressure is then reduced to 0.5atm.

If we apply this information to the equation for Boyle’s law, we get
2L * 3atm = 0.5atm * V2.

Through arithmetic, we find that
6 = 0.5atm * V2
6/0.5atm = V2
12L = V2.

So, the volume of the balloon is 12L.

Hope this helps!

Which formula contains two no-metals a NaBr B BaO C KI D So O2​
cricket20 [7]

Answer:

D. SO₂

Explanation:

  • Non-metals are elements that react by gaining electrons to attain a stable configuration and form an anion.
  • Non-metal elements are found in groups, 5, 6, 7 and 8 of the periodic table. Halogens are an example of non-metals that gain an electron to form anions.
  • SO₂ is a compound whose molecule contains sulfur and oxygen which are non-metals. The sulfur and oxygen atoms are joined together by a covalent bond to form SO₂.

Rank the following compounds in order of decreasing solubility in water: CH3CH2−OH Ethanol CH3CH2CH2CH2−OH Butanol CH3CH2CH2CH2C
Alik [6]
Order of Solubility of given alcohols is as follow,

                     Ethanol                  Butanol                   Hexanol

Highly Soluble ---------->--------------------->------------------------>---Slightly Soluble

As we know Like dissolves Like. Water is a polar solvent and dissolves readily those compounds which are polar in nature. The solubility of all these alcohols is due o the -OH (hydroxyl) group which tends to form Hydrogen Bond interactions with the water molecules. The difference comes in the alkyl group of these compounds. The akyl group is non polar in nature and immiscible in water. As the non polar chain increases from ethanol to hexanol, so the solubility also decreases from ethanol to hexanol.
