You have been given an orange liquid and told to describe its properties.

chubhunter [2.5K]

Answer:

The correct answer would be - observing with the help of five senses.

Explanation:

To find and describe the physical properties of the given substance or the solution or liquid students can observe using their five senses. By looking at the liquid one can find its state and color, by smelling students can find the odor of the sample, by touching it one can observe and describe the texture.

Fluidity can also be measure by the touch if the solution is viscous or free-floating. By using a thermometer and using a graduated cylinder one can find the temperature at room temperature and the weight of substance respectively.

Write the chemical equation for the reaction of lithium hydroxide (LiOH) with an Arrhenius acid of your choosing. Name and write

Inessa05 [86]

<h3>Answer:</h3>

LiOH(aq) +HCl(aq)→ LiCl(aq) + H₂O(l)

Salt formed is LiCl

<h3>Explanation:</h3>

Arrhenius acid refers to a substance that ionizes in water to generate protons or hydrogen ions.
Examples of Arrhenius acid include acids such as HCl, H₂SO₄ and HNO₃.
A reaction between Lithium hydroxide and an Arrhenius acid such as HCl will yield a salt and water.

That is;

LiOH(aq) +HCl(aq)→ LiCl(aq) + H₂O(l)

The salt formed is LiCl
The reaction is an example of neutralization reaction.

A car is traveling 83.3 kilometers per hour. What is its speed in miles per minute? One kilometer = 0.62 miles.

Leya [2.2K]

Hi. 2fouls! :)

First convert the number from kilometer to miles:
$83.3*0.62$
$=51.646 miles$

Now to find the miles per minutes,divide the miles per hours by 60 (the amount of minutes in an hour.)

$51.646/60$
$=0.860766667$

The car is travelling at a speed of 0.860766667 miles/minute.

Hope this helps.

What is the number of the lowest energy level that contains an f sublevel?

forsale [732]

Answer: n = 4.

Explanation:

1) The main energy level is represented by the principal (main) quantum number, n. It can be 1, 2, 3, 4, 5,6, or 7. It is the period number in the periodic table.

2) The next quantum number is the Azimuthal quantum number (ℓ), also known as angular quantum number. It indicates the subshell (sublevel) or type of orbital.

This quantun number may be:

s, p, d, or f.

3) For n = 1, there is only one ℓ number: 0; which is the orbital s

For n = 2, there are two possible ℓ numbers: 0 and 1; which are the orbitals s and p.

For n = 3, there are three possible ℓ numbers: 0, 1, and 2, which are the orbitals s, p, and d:

For n = 4, there are four possible ℓ numbers:0, 1, 2, and 3; which are the orbitals s, p, d, and f.

So, the f sublevel appears first time when n = 4, i.e the number of the lowest energy level that contains an f sublevel is 4.
