Answer:
solids have definite shape and volume. liquid have definite volume but not definite shape. gases do not have definite volume as well as definite shape.
Answer:
See explanation
Explanation:
The most accurate method of determining the volume of an object, is the water displacement method. It has the peculiar advantage of working well with irregular solids.
There are often errors that prevent exact measurements of the volume of objects. This makes the water displacement method a preferred and easier method of determining the volume of an object.
The crude oil is heated in a process of fractional distillation (note: you can research this online if you require more detail) and this process causes different hydrocarbons to condense at different heights up the distillation column. They will therefore run down the side of the column and into different areas depending on their boiling point.
Answer:
The electron stays in an excited state for a short time. When the electron transits from an excited state to its lower energy state, it will gice off the same amound of energy needed to raise to that level. This emitted energy is a photon.
Answer:
The answer to your question is 194 g
Explanation:
Molecular mass is the sum of all the masses of the atoms that form a molecule.
In the problem, we have C₈H₁₀N₄O₂ which means
atomic mass number of atoms total
Carbon 12 8 12 x 8 = 96
Hydrogen 1 10 1 x 10 = 10
Nitrogen 14 4 14 x 4 = 56
Oxygen 16 2 16 x 2 = 32
194 g
