How are carbohydrates and lipids similar? how are they different?

1 answer:

6 0

"Lipids are like carbohydrates in way that the true fats contain only carbon, hydrogen, and oxygen. Both carbohydrates and lipids act as the main fuels and energy storage compounds of the human body. They are also called SACCHARIDES and grouped as: Monosaccharides, Disaccharides, Trisaccharides, Polysaccharides."

Can you describe the situations when Greek prefixes are used?

Black_prince [1.1K]

Answer:

Here's what I get

Explanation:

At the introductory level of chemistry, I can think of only two situations when you use Greek prefixes.

They indicate the number of atoms or groups in a molecule when you are naming a compound.

1. Binary covalent compounds

For example, P₂S₅ is diphosphorus pentasulfide.

2. Hydrates

For example, Na₂SO₄·10H₂O is sodium sulfate decahydrate.

Compounds A, B, and C react according to the following equation. 3A(g) + 2B(g) 2C(g) At 100°C a mixture of these gases at equili

Vedmedyk [2.9K]

Answer:

The value of Kc for the reaction is 3.24

Explanation:

A reversible chemical reaction, indicated by a double arrow, occurs in both directions: reagents transforming into products ( direct reaction) and products transforming back into reagents (inverse reaction)

Chemical Equilibrium is the state in which direct and indirect reactions have the same reaction rate. Then taking into account the rate constant of a direct reaction and its inverse the chemical constant Kc is defined.

Being:

aA + bB ⇔ cC + dD

where a, b, c and d are the stoichiometric coefficients, the equilibrium constant with the following equation:

$Kc=\frac{[C]^{c} *[D]^{d} }{[A]^{a} *[B]^{b} }$

Kc is equal to the multiplication of the concentrations of the products raised to their stoichiometric coefficients divided by the multiplication of the concentrations of the reagents also raised to their stoichiometric coefficients.

Then, in the reaction 3A(g) + 2B(g) ⇔ 2C(g), the constant Kc is:

$Kc=\frac{[C]^{2} }{[A]^{3} *[B]^{2} }$

where:

[A]= 0.855 M
[B]= 1.23 M
[C]= 1.75 M

Replacing:

$Kc=\frac{1.75^{2} }{0.855^{3}*1.23^{2} }$

Solving you get:

Kc=3.24

The value of Kc for the reaction is 3.24

Which best explains how insects help flowering plants in reproduction?

ankoles [38]

Answer:

if insects helps in pollination that is called entomophily

Explanation:

Some plants having attractive odor and color which attracted the insects towards it and when they come in contact with flowering plant the seed or pollens which is produced by the male part of plant got attached to their body and when insects travels to other flowering plants pollens sheds to stigma which is female part of flower and in results fertilization occur.

Which element has 5 outer electrons in its 3rd shell?

Sloan [31]

Answer:

Explanation:

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on.
