Answer:
Total mass of original sample = 0.38 g
Explanation:
Percentage of chloride = 74.5%
Mass of AgCl precipitate = 1.115 g
Mass of original sample = ?
Solution:
Mass of chloride:
1.115 g/ 143.3 g/mol × 35.5 g/mol
0.0078 g × 35.5 = 0.28 g
Total mass of compound:
Total mass = mass of chloride / %of Cl × 100%
Total mass = 0.28 g/ 74.5% × 100%
Total mass = 0.0038 g× 100
Total mass = 0.38 g
Answer:
A
Explanation:
they usually have that Crystal like thing in them... since they are formed from Lava
The red bottle would have the lowest frequency because red light has the longest wavelengths. The light passing through the violet would have the highest frequency because its wavelengths are the shortest.
A representative particle is the smallest unit of a substance that can be broken down without altering the composition. Matter is composed of three types of representative particles: atoms, molecules and formula units.
Atoms and Elements
Atoms are the smallest particle that can be split. Substances that contain only one kind of atom are called elements.
Molecules
The molecule is the representative particle of molecular compounds. It is also the representative particle of diatomic elements.
Formula Unit
The representative particle of an ionic compound is the formula unit. A formula unit uses a formula to calculate the basic whole number ratio of the ions in an ionic compound.
Diatomic Elements
Diatomic elements, or molecules, are made up of two atoms of the same element. These diatomic elements are not part of a compound.
