<h3>What are hydrocarbon?</h3>

An organic substance called a hydrocarbon is made completely of hydrogen and carbon. Group 14 hydrides include, for example, 620 hydrocarbons.

The odours of gasoline and lighter fluid serve as examples of the relatively weak or insignificant odours of hydrocarbons, which are often colourless and hydrophobic.

They can be found in a wide variety of chemical forms and phases, including gases (like methane and propane), liquids (like hexane and benzene), low melting point solids (like paraffin wax and naphthalene), and polymers (such as polyethylene and polystyrene).

In the context of the fossil fuel industries, the term "hydrocarbon" refers to petroleum, natural gas, and coal that are produced naturally, as well as to their hydrocarbon derivatives and refined forms. The primary source of energy for the entire planet is the burning of hydrocarbons.

A(g) + 2B(g) → C(g) + D(g)

WITCHER [35]

Answer:

0.169

Explanation:

Let's consider the following reaction.

A(g) + 2B(g) ⇄ C(g) + D(g)

We can find the pressures at equilibrium using an ICE chart.

A(g) + 2 B(g) ⇄ C(g) + D(g)

I 1.00 1.00 0 0

C -x -2x +x +x

E 1.00-x 1.00-2x x x

The pressure at equilibrium of C is 0.211 atm, so x = 0.211.

The pressures at equilibrium are:

pA = 1.00-x = 1.00-0.211 = 0.789 atm

pB = 1.00-2x = 1.00-2(0.211) = 0.578 atm

pC = x = 0.211 atm

pD = x = 0.211 atm

The pressure equilibrium constant (Kp) is:

Kp = pC × pD / pA × pB²

Kp = 0.211 × 0.211 / 0.789 × 0.578²

Kp = 0.169

Ham radio operators often broadcast on the 6-meter band. The frequency of this electromagnetic radiation is MHz. [speed of light

Volgvan

Answer:

50 MHz

Explanation:

The relation between frequency and wavelength is shown below as:

$c=frequency\times Wavelength$

c is the speed of light having value $3\times 10^8\ m/s$

Given, Wavelength = 6 m

Thus, Frequency is:

$Frequency=\frac{c}{Wavelength}$

$Frequency=\frac{3\times 10^8}{6}\ Hz$

$Frequency=50\times 10^{6}\ Hz$

Also,

Also, 1 Hz = $10^{-6}$ MHz

So,<u> Frequency = 50 MHz.</u>

How will vinegar slow down the break down of an apple?

Gennadij [26K]

Answer:

Many people take apple cider vinegar before protein-heavy meals to improve digestion. The theory is that apple cider vinegar increases the acidity of your stomach, which helps your body create more pepsin, the enzyme that breaks down protein
