The following directions for diluting a 10.0 M answer to a 1.00 M solution is no longer correct.
<h3>.What is the rule of dilution?</h3>
A popular rule to use in calculating the attention of solutions in a sequence is to multiply the unique concentration by means of the first dilution factor, this by the second dilution factor, this by the 1/3 dilution factor, and so on till the ultimate attention is known.
Example: A 5M answer of HCl is diluted 1/5.
<h3>How do you do a 1 in 10 dilution?</h3>
For example, to make a 1:10 dilution of a 1M NaCl solution, you would combine one "part" of the 1M solution with 9 "parts" of solvent (probably water), for a total of ten "parts." Therefore, 1:10 dilution ability 1 part + 9 components of water (or different diluent).

Answer:
A compound has atoms with different elements chemically combined in a completed ratio. An element is a chemical substance made of another type of atom.
Answer:
Sulfur
Explanation:
You find the identity by looking at the number of protons. The number of protons never change for an element.
Answer:
Number of neutrons: 44
Number of protons: 34
Number of electrons: 36
Explanation:
The atomic number of Se (Selenium) is 34
Mass number is 78
Number of neutrons = mass number - atomic number = 78 - 34 = 44
Number of protons is the same as the atomic number
Number of protons = 34
Selenium ion has a charge of -2. This means it accepts two more electrons
Number of electrons = atomic number + 2 = 34 + 2 = 36
