Draw an example each of a hydrogen atom that can and can’t participate in hydrogen bonding.

Chemistry
1 answer:
frutty [35]3 years ago

Answer:

A hydrogen bonding is a bond class that is produced from the attraction existing in a hydrogen atom and an oxygen, fluorine or nitrogen atom with a negative charge. This attraction, meanwhile, is known as dipole-dipole interaction and links the positive pole of one molecule with the negative pole of another.

Explanation:

The hydrogen atom, which has a positive charge, is known as the donor atom, while the oxygen, fluorine,  chlorine or nitrogen atom is the bond acceptor atom. In the substance in which they are most effective is in the water.

Hydrogen bonds have only one third of the strength of covalent bonds, but they have important effects on the properties of the substances in which they occur, especially in terms of melting and boiling points in crystal structures.

suppose a student poured equal volumes of water and naoh in two different flasks. he forgets to label his flasks and is confused
ArbitrLikvidat [17]

The one with higher temperature is the one with NaOH as heatis given off during the neutralization reaction that occurs.

<h3>What is volume?</h3>

Volume can be defined as the amount of space a substance or an objects occupies usually in a closed container.

Volume is measures in litres.

When water is added to dilute acid like HCl, they become more dilute.

When NaOH is added to HCl, a neutralization reaction occurs.

The student will determine the contents of the flasks by adding 10 ml of hcl to each flask. If the NaOH reacts with the Hcl, there will be an increase in temperature.

The increase in temperature is due to the heat of neutralization of the reaction between NaOH and HCl.

Usimov [2.4K]

Answer:

The answer is "0.0000190 and 2.7 J".

Explanation:

\to P_4=\frac{e^{-\beta}(4+\frac{1}{2}) hev}{2vb}\\\\

         =\frac{e^{-9(1.35)}}{0.278v}\\\\=\frac{e^{-12.5}}{0.278}\\\\=\frac{0.000005285}{0.278}\\\\=0.0000190

Given:

h=6.626 \times 10^{-34}\\\\c=3\times 10^{10}\\\\v=558\ cm^{-1}\\\\K=1.38 \times 10^{-23}\\\\ T=298\\\\

E=\frac{hcv}{KT}\\\\

by putting the value into the above formula so, the value is 2.7 J

What is the mass of carbon in 500. g of octane?
denis23 [38]

The answer is: the mass of carbon is 420.6 grams.

m(C₈H₁₈) = 500 g; mass of octane.

M(C₈H₁₈) = 114.22 g/mol; molar mass of octane.

n(C₈H₁₈) = m(C₈H₁₈) ÷ M(C₈H₁₈).

n(C₈H₁₈) = 500 g ÷ 114.22 g/mol.

n(C₈H₁₈) = 4.38 mol; amount of octane.

In one molecule of octane, there are eight carbon atoms:

n(C) = 8 · n(C₈H₁₈).

n(C) = 8 · 4.38 mol.

n(C) = 35.02 mol; amount of carbon.

m(C) = 35.02 mol · 12.01 g/mol.

m(C) = 420.6 g; mass of carbone.
