Answer:
Conditions to Avoid: Natural gas is extremely flammable and explosive; avoid heat, sparks, open flames, and all possible sources of ignition. Heat will increase pressure in containers used to store natural gas.Jun 1, 2015
Answer:
Natural Gas can be explosive or flammable depending on it's concentration in air.
Natural gas has a flammability range of approximately 5 to 15 percent.
Any percentage greater than that is explosive for natural gas.

If we shake the branches of the tree the fruits fall.why?
Answer:
When we shake the branch of a tree the tree possesses a state of motion whereas the fruits and leaves tend to remain in state of rest. Due to this inertia of rest the fruits and leaves get detached from the branch and because of gravity it falls down.
Explanation:
so it's because of the gravity .

Answer: option A
The electrons are attracted to the protons
Explanation:
Electrostatics is a force that pull or push objects without the objects actually touching them.
Electrons have a negative charge and protons have a positive charge. Positive and negative attract each other so therefore the electrons are attracted to the protons.
It’s not B because the electrons aren’t 100% pushing away from the nucleus.
It’s not C because the electrons are not attracted to the neutrons. Neutrons don’t have a charge; they have a net zero charge.
It’s not D because the electrons can’t attract each other. Electrons have a negative charge and negative charges don’t attract each other; they push away from each other instead.
Hope that helps.
If you need a better explanation just let me know
Noble gases are the least reactive elements on the periodic table.
A. True
B. False
Answer:
The statement is True!"Why?"The Noble Gases have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.
Hope this helps!

5. The tradition of giving teachers an apple goes back to 19th century Denmark, where
teachers didn't earn enough for food. So, parents would send their children to school
with an extra snack for the teacher. Would current stdents' grades increase if they
brought in treats for their teachers?
Make a hypothesis help plz
Answer:
The apple, that innocent bud of an Americana autumn, has pulled off one of the greatest cons of all time. As students across the country prepare to greet a new school year and teacher with a polished bit of produce, the apple cements its place in the patriotic foods pantheon despite its dodgy past.
Answer:
If students brought an extra snack for their teachers it doesn't necessarily mean their grades would increase, but it's not impossible. A lot of teachers today might view it as being something like a suck-up. However, I do know that there are teachers who might be touched by such gestures and give the students extra attention, with this their grades might improve with the extra attention.

Draw the structural formula (using C and H) for 2-octene. (ASAP! 65 POINTS!)
Because there are 6 carbon molecules in 2-octene, we will place down 6 carbons. Carbons usually form a backbone, so they will be lay in a flat line. You can then add 3 H on both the Hydrogens at the ending to create symmetry, and keep filling Hydrogen on both sides and try to creat symmetry until you only have 2 H left. Place 1 H above a C and 1 H below a C so the remaining 2 carbons can then double bond to each other and form a complete octet.

What are the problems of turbid water for aquatic plants?
Answer:
Turbidity affects the growth rate of algae (micro-aquatic plants) and other aquatic plants in streams and lakes because increased turbidity causes a decrease in the amount of light for photosynthesis. Turbidity can also increase water temperature because suspended particles absorb more heat.High levels of turbidity can affect aquatic life in several ways.
Too much turbidity might make it difficult for plants to complete photosynthesis, which in turn affects the amount of dissolved oxygen.Fish cannot see well in turbid water making finding food difficult.High turbidity reduces the penetration of sunlight into water and can limit photosynthesis and hence the growth of aquatic plants.Explanation:
Turbidity is the measure of relative clarity of a liquid. The higher the intensity of scattered light, the higher the turbidity. Material that causes water to be turbid include clay, silt, very tiny inorganic and organic matter, algae, dissolved colored organic compounds, and plankton and other microscopic organisms

Naturally, an atom is neutral in charge? Why?
Answer:
Atoms are electrically neutral because they contain equal quantities of positively charged protons and negatively charged electrons. Electrons and protons have equal but opposite charges, so the result is no net charge. Ions are atoms that have gained or lost electrons.
Determine the type of alcohol corresponding to each given description or name. 3-ethyl-3-pentanol Choose... An alcohol with two other carbons attached to the carbon with the hydroxyl group Choose... An alcohol with three other carbons attached to the carbon with the hydroxyl group Choose... 1-pentanol Choose... 2-hexanol Choose... An alcohol with one other carbon attached to the carbon with the hydroxyl group Choose...
Answer:
An alcohol with three other carbons attached to the carbon with the hydroxyl group
An alcohol with two other carbons attached to the carbon with the hydroxyl group
Explanation:
If we look at 3-ethyl-3-pentanol, we will discover that the compound is a tertiary alcohol. That is, the carbon atom bearing the hydroxyl group is attached to three other carbon atoms as gown in image 1 attached.
For 2-hexanol, the carbon atom bearing the hydroxyl group is attached to two other carbon atoms hence the alcohol is a secondary alcohol. The compound is shown in image 2 attached.

¿Como pasar 254 meses a minutos?
Por favor ayudaaa!!
Le doy corona a la respuesta
Answer:
Ver las respuestas abajo.
Explanation:
Este problema se puede resolver conociendo la relacion entre horas y minutos, sabemos que:
1 hora [h] → 60 minutos [min]
De esta manera:
2 [min] = 2/60 = 0.033 [h]
15 [min] = 15/60 = 0.25 [h]
30 [min] = 30/60 = 0.5 [h]
10 [min] = 10/60 = 0.166 [h]
6 [min] = 6/60 = 0.1 [h]
20 [min] = 20/60 = 0.33 [h]
5 [min] = 5/60 = 0.0833 [h]

Which of the following isotopes would deflect the most in a mass spectrometer?
a) Sr-84
b) Sr-86
c) Sr-87
d) Sr-88
The correct answer is Sr-84. The lightest specie is the most deflected while the heaviest specie is the least deflected.
In mass spectroscopy, chemical substances can be identified by looking at their respective mass-to-charge ratios of gaseous ions in electric and magnetic fields. The is achieved using a mass spectrometer.
The lightest specie undergoes the greatest deflection while the heaviest specie undergoes the heaviest deflection accordingly in a mass spectrometer.
In this case, Sr-84, is the lightest specie hence it should be the least deflected specie.

what more accurate model of the atom emerged from Albert Einstein's contributions and quantum mechanics
Answer:
Einstein also in 1905 mathematically proved the existence of atoms, and thus helped revolutionize all the sciences through the use of statistics and probability. Atomic theory says that any liquid is made up of molecules (invisible in 1905)
Explanation:
Answer:
The discoveries of Albert Einstein led to development in the understanding of the atom through the study of quantum mechanics and the electron cloud. In this model, there is still a nucleus with protons and neutrons. But unlike the Bohr model, the electrons exist in a cloud outside the nucleus, much like the fruit around the pit of a peach.
