Explanation:

Organic compounds, which are the compounds associated with life processes, are the subject matter of organic chemistry. Among the numerous types of organic compounds, four major categories are found in all living things: carbohydrates, lipids, proteins, and nucleic acids.

How do glaciers cause erosion and deposition

koban [17]

Like flowing water, flowing ice erodes the land and deposits the material elsewhere. Glaciers cause erosion in two main ways: plucking and abrasion.
Plucking is the process by which rocks and other sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice.
The other way you'll need more informations because my Knowledges are limited by here.

A solution prepared by dissolving 0.100 mole of propionic acid in enough water to make 1.00 L of solution is observed to have a

torisob [31]

Answer:

C) $k_a=1.3\times 10^{-5}$

Explanation:

pH is defined as the negative logarithm of the concentration of hydrogen ions.

Thus,

pH = - log [H⁺]

The expression of the pH of the calculation of weak acid is:-

$pH=-log(\sqrt{k_a\times C})$

Where, C is the concentration = 0.5 M

Given, pH = 2.94

Moles = 0.100 moles

Volume = 1.00 L

So, $Molarity=\frac{Moles}{Volume}=\frac{0.100}{1.00}\ M=0.100\ M$

C = 0.100 M

$2.94=-log(\sqrt{k_a\times 0.100})$

$\log _{10}\left(\sqrt{k_a0.1}\right)=-2.94$

$\sqrt{0.1}\sqrt{k_a}=\frac{1}{10^{2.94}}$

$k_a=1.3\times 10^{-5}$

Electrolysis of molten lead bromide is carried out.

bearhunter [10]

Answer:

Read Below

Explanation:

Electrolysis is not possible with solid lead (II) bromide. This is because the ions are held in a three-dimensional lattice, unable to move freely to the electrodes. Melting enables the ions to become mobile and to travel to the respective electrodes.

The bulb won't glow when the electrodes are embedded in solid lead bromide. The bulb will glow when the material surrounding the electrodes is molten lead bromide. When an ionic compound is in the molten (liquid) form the positive and negative ions are free to move around.

A sample of gas has a volume of 1.40 L at a pressure of 225 mmHg. What is the new volume at a pressure of 515 mmHg?

guajiro [1.7K]

Answer:0.61L

Explanation:

P1V1/n1T1=P2V2/n2T2

n1=n2 T1=T2

Therefore;

P1V1=P2V2

225×1.4=515×V2

V2=0.61L

N.B: Increase in pressure leads to decreases in volume (Boyle's law)

<h3>Answer:</h3>

d) 1 and 4

<h3>Explanation:</h3>

Elements are made up of particles known as atoms.
Atoms of the same element have the same properties as the element.
The atoms of an element may differ in terms of the number of neutrons and have a different mass number, such atoms are known as isotopes.
However, the isotopes have an equal number of protons or atomic number.
In this case, atom 1 has a mass number of 20 and an atomic number of 10 while atom 4 has a mass number of 21 and an atomic number of 21.
Therefore, atom 1 and 4 are isotopes of element E.
