AleksAgata [21]4 years ago
4 0
Amount of a substance (called the solute) that dissolves in a unit volume of a liquid substance (called the solvent) to form a saturated solution under specified conditions of temperature and pressure. Solubility<span> is expressed usually as moles of solute per 100 grams of solvent.</span>

What substance is added during hydrolysis in order to break down food macromolecules?
TEA [102]
Hey there! :D

Look at the word hydrolysis. Hydro= water Lysis = split. (Root words) 

So, water (in terms of the word) is added to help split and breakdown macromolecules. 

I hope this helps!

If the volume and moles of a container are held constant, the temperature of a gas is inversely proportional to the pressure.
noname [10]

Answer:

FALSE

Explanation:

Assuming that the gas is ideal

Therefore the gas obeys the ideal gas equation

<h3>Ideal gas equation is </h3><h3>P × V = n × R × T</h3>

where

P is the pressure exerted by the gas

V is the volume occupied by the gas

n is the number of moles of the gas

R is the ideal gas constant

T is the temperature of the gas

Here volume of the gas will be the volume of the container

Given the volume of the container and number of moles of the gas are constant

As R will also be constant, the pressure of the gas will be directly proportional to the temperature of the gas

P ∝ T

∴ Pressure will be directly proportional to the temperature

Describe the orbital diagram of an atom with eight electrons. Explain how this orbital diagram demonstrates Hund's rule. PLEASE
Mama L [17]

Answer:

The orbital notations shows the sequence of filling electrons into the orbitals of sublevels. This filling is based on some certain principles. For an atom with 16 electrons, the orbital diagram is shown below:  1s²2s²2p⁶3s²3p⁴ The maximum number of electrons in each sublevel of the orbitals are: 2 electrons for s-sublevel with one orbital

                 6 electrons for p-sublevel with three orbital

                 10 electrons for d-sublevel with five orbital

                 14 electrons for f-sublevel with seven orbital

According to the Aufbau's principle, sublevels with lower energy are filled before those with higher energy.

                           1s 2s 2p 3s 3p 4s 3d etc

Pauli's exclusion principle shows that no two electrons can have the same set of values for the four quantum numbers. Simply, no two electrons can spin in the same direction. Hund's rule states that electrons go into degenerate orbitals of sub-levles(s,p,d and f) singly before pairing commence. This rule shows that in each energy level, as the electron goes into the degenerate orbitals, they fill it one by one before they begin to pair up. As we know, each degenerate orbital can only accomodate 2 electrons. From the orbital diagram 1s²2s²2p⁶3s²3p⁴, the 3p sublevel has 3 orbitals. In each of the orbitals, two electrons would occupy them to give a maximum capacity of 6. But the sublevel has just 4 electrons. Based on Hund's rule, an electron will go into each of the 3 orbitals first. The remaining electron will now pair with the first degenerate orbital. This makes a total of 4 electrons.
