Answer:
b.) methane and long branches alkanes
Explanation:
Petroleum or crude oil is a fossil fuel formed by the decomposition of organisms buried under the earth's surface and subjected to intense pressure and temperature. It is composed of a mixture of hydrocarbons which include paraffins (linear and branched alkanes), naphthenes (cyclic alkanes) and other aromatic compounds.
However, petroleum is predominantly consists of paraffins which have the general formula CnH2n+2 and include methane and other long branched alkanes.
Instability
Explanation:
Isotopes decays because they are unstable. Stable isotopes do not decay.
- For every atomic nucleus, there is a specific neutron/proton ratio.
- This ratio ensure that a nuclide is stable.
- For example, fluorine F, is 10/9 stable.
- Any nucleus with a neutron/proton combination different from its stability ratio either too many neutrons or too many protons will become unstable.
- Such nuclide will split into one or more other nuclei with the emission of small particles of matter and considerable amount of energy.

Answer:
150mL
Explanation:
First, let us calculate the volume of the diluted solution. This is illustrated below:
Information obtained from the question include:
V1 (initial volume) = 50mL
C1 (initial concentration) = 1M
C2 (final concentration) = 0.25M
V2 (final volume) =.?
The volume of the diluted solution can be obtained using the dilution formula C1V1 = C2V2 as shown below:
C1V1 = C2V2
1 x 50 = 0.25 x V2
Divide both side by 0.25
V2 = 50/0.25
V2 = 200mL
The volume of the diluted solution is 200mL.
Now, to obtain the volume of the water added to the solution, we'll simply subtract the initial volume from the final volume as shown below
Volume of water added = V2 - V1
Volume of water added = 200 - 50
Volume of water added = 150mL
Therefore, the volume of water added is 150mL
Answer:
Tornados could be possible or storms
Explanation:
Answer:
Water has the greatest ΔEN
ΔEN H₂O → 3.4 - 2.1 = 1.3 Option D.
Explanation:
We should find the Electronegativity data in the Periodic table for all the elements:
C : 2.6
O: 3.4
H: 2.1
S: 2.6
N: 3.0
a. ΔEN CO₂ → 3.4 - 2.6 = 0.4
b. ΔEN H₂S → 2.6 - 2.1 = 0.5
c. ΔEN NH₃ → 3 - 2.1= 0.9
d. ΔEN H₂O → 3.4 - 2.1 = 1.3
