Answer: (although the question does not sate whether if you separate them physically or through energy. so i did both)
1. can be separated (When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen)
2. can be separated, but through electrolysis, fiscally moving a crane to generate electricity to separate the molecules
3. Most solid particles, composed of diamagnetic or weak paramagnetic materials, cannot be extracted by a conventional magnetic separator. physically cannot be separated. but through heat yes
4. but there is a catch: doing so requires energy. ... If energy from coal were applied to drive the decomposition reaction, more CO2 would be released than consumed, because no process is perfectly efficient. so it cant be separated physically
5. it can be separated but it needs energy physically cannot be separated.
Explanation:
Answer:
An isotope is an element that has a different amount of neutrons than its standard atomic mass. ... Subtract the number of protons from the atomic mass. This is the number of neutrons that the regular version of the atom has. If the number of neutrons in the given atom is different, than it is an isotope.
Explanation:
Tumor cells differ from normal cells in that A) Mitosis is not regulated in tumor cells.
This is seen when tumors grow to large amounts rather quickly. Mitosis is not regulated, and therefore the cells continue to multiply and that is when we are able to see and feel a palpable cancer mass - their growth is uncontrolled.
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.
Answer:
98
Explanation:
The first 98 elements occur naturally, although 10 of them are found in extremely small amounts.
The elements from Element 99 up are so unstable that they must be produced artificially.
