The answer is +1! Have a great day!
When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. ... The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.
Answer: They are referred to as isotopes, which are a form of an element that has different numbers of neutrons in their nucleus.
The answer is A. In case you wanted to know, the actual answer is 4.184. If anything is unclear, just ask!
Explanation:
Fundamentally the aluminum foil is a rectangular prism. It has a length, a width, and a thickness.
The volume of a rectangular prism is expressed as
If we know the volume and two of the three dimensions, we can rearrange the equation to solve for the thickness.
But we should also be sure to confirm our units.
A liter is defined as 1000 cm^3. Therefore a mL is equal to 1 cm^3.
You should convert the units of measure given in the problem statement such that the units are aligned. For example, 10.0mm will be 1 cm and 12.5m will be 1250 cm. This will give you a height in cm.
