Hi there! Let's solve this problem shall we!
⠀Volume = 10g
Mass = 2 mL
In this specific problem, they are asking us to find the <u><em>density </em></u>of the object. So,<u><em> using the information given to us</em></u> (volume and mass), let's solve the problem!
Now, if you remember, D = M ÷ V
So, let's fill in the blanks!
D = Our unknown value
M = 2mL
V = 10g
Here is the filled out formula:
D = M ÷ V
D = 2mL ÷ 10g
D = 5 g/mL
*Make sure you put the units for your final solution!*
- Compounds are formed when two or more <u>elements</u> are chemically combined.
- When these elements are <u>chemically</u> combined, a new substance is formed with new chemical and physical <u>properties</u>.
- An element is a <u>pure</u> substance that cannot be separated into simpler substances by <u>physical</u> or chemical means.
- A compound is two or more elements <u>combined</u> chemically to produce a new substance.
- When two or more elements chemically combine, the compound has new properties, different from the chemical and physical properties of the <u>original</u> elements.
<h3>What is a chemical element?</h3>
A chemical element can be defined as a pure substance which comprises atoms that have the same atomic number (number of protons) in its nuclei and as such it is the primary constituent of matter.
Generally, some examples of a chemical element include the following:
- Argon.
- Sodium.
- Carbon.
- Oxygen.
- Hydrogen.
- Phosphorus
- Copper
- Aluminum
- Potassium
- Magnesium
<h3>What is a pure substance?</h3>
A pure substance can be defined as a single sample of matter that cannot be separated into other kinds of matter through the use of any physical or chemical separating technique because it has distinct chemical properties and a definite and constant composition.

electrons in the outer shell have the lowest ionization energy. (not even gonna consider the quantum model which does funny things with d-sublevel). Highest ionization energy in descending order is:
Ar = 1520.6
Si = 786.5
Al = 577.44
Na 495.8
Answer:
Explanation:
If by speed ,you mean the rate at which they collide with each other then yes the answer would be
By decreasing the temperature
Since we already know thattemperature is the average kinetic energy of the molecules and increasing temperature will increase the motion of the solvent molecules and an decrease in temperature will decrease in the motion of solvent molecules
O2 is an element As it contains just one kind of atom, O2 is an element,
