Answer:
answer is C
Explanation:
encourage the release of carbon dioxide from the stems
Answer:
neutrons, isotope
Explanation:
Isotopes are atoms of the same element with different atomic mass. The difference in atomic mass is as a result of difference in the number of neutrons in the nuclei of the atoms.
Hence, changing the number of neutrons of an atom with result in having different atomic mass but the number of protons and electrons remain the same.
The correct answers are A, B, and C
- For example, hydrogen and oxygen are two elements that form to create water. Water is more complex than a simple atom of hydrogen or one of oxygen.
- Decomposition is an example of B
- Burning is an example of C.
D is not right because a chemical change can only join atoms or rearrange them, not completely change them.
The Earth's early atmosphere consisted of Carrbon Dioxide, methane, sulphur, ammonia, nitrogen and smaller amounts (aprox. 0.05%) of other gases.
Answer:
34.9103 or 34.9 g
Explanation:
Remember Density is a broken heart: m/v.
In this scenario (Let x = # of grams in the sample of gasoline),
D = 0.7198 g/mL = x g / 48.5 mL
So,
(0.7198 g/mL) * (48.5 mL) = x g
x g = 34.9103 = 34.9 g (Accounting for Significant Figures)
