When fossil fuels, such as gasoline, are burned, they create smoke. Smoke is best described as a heterogeneous mixture of solid particles from the burning fuel dispersed in a gas – usually air. Smoke can be described more specifically as a suspension. What will most likely happen over time to smoke in the atmosphere? The solid particles will spread out and dissolve. The particles will eventually come together in a cloud and produce rain. Over time, the solid particles will settle on whatever is outside. The particles will remain mixed in the air.
Answer:
Over time, the solid particles will settle on whatever is outside."

Fossils of sea creatures have been found near the top of Mount Everest (8848m above the sea level). How do you think they could have got there?
Answer:
Continental Drift
Explanation:
The fossils of sea creatures could have reached the top of Mount Everest due to the continental drift theory suggested by geophysicist, Alfred Wegener. To exaggerate, a piece of evidence that supports Wegener’s hypothesis towards a continental drift is the fact that fossils of sea creatures can’t just end up in any random place like Mount Everest. He suggests that there must be something behind this and gradually it led to his well-known theory. His hypothesis towards a continental drift suggests that his second observation was that fossils of the same prehistoric species were found in different continents that were way apart. There was just no way that all the organisms could cross the oceans and reach all of these places.
Explain why nervous signals are described as an "electrochemical process." What is electrical and what is
chemical? Make sure to use these terms (axon, synapse, neurotransmitter, action potential, Na/k pump, dendrite, axon
terminals).
Answer:
The nervous system operates using an electrochemical process. An electrical charge moves through the neuron itself, and chemicals are used to transmit information between neurons

Determine the pressure of a 6.4L sample of oxygen gas at 300K and 100KPa, after the gas is compressed to 2.40L at 900K.
The pressure : 800 kPa
Further explanationBoyle's law and Gay Lussac's law
[tex]\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}[/tex]
P1 = initial gas pressure (N/m² or Pa)
V1 = initial gas volume (m³)
P2 = gas end pressure
V2 = the final volume of gas
T1 = initial gas temperature (K)
T2 = gas end temperature
The pressure after the gas is compressed :
[tex]\tt \dfrac{100\times 6.4}{300}=\dfrac{P_2\times 2.4}{900}\\\\P_2=800~KPa[/tex]
Write the general formula of an alkane and use this to predict the 97th member
of the alkane series.
Explanation:
The general formula of an alkane is given as;
CₙH₂ₙ₊₂
n is the number of the member;
For the 97th member in the series;
n = 97;
2n + 2 = 2(97) + 2 = 196
So, the 97th member is;
C₉₇H₁₉₆
This is how to apply the formula of alkanes which are saturated hydrocarbons to find any member of the series.

If the decay has a half-life of 10.2 years, what mass of 60.8g carbon-14 will remain after 20.4 years
Answer:
15.2 g.
Explanation:
After 10.2 years mass remaining = 60.8 * 1/2 = 30.4 g
After another 10.2 years it is 30.4 * 1/2 = 15.2 g.

A 975 L balloon contains helium. On the ground the temperature is 30 0C and the pressure is 743 torr. What will be the balloon's volume at an altitude of 5700 m where the pressure is 375 mm Hg and the temperature is -35.0 0C?
Answer:
V₂ = 1518L
Explanation:
-Using combined gas law:
[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]
Where P is pressure, V is volume and T is absolute temperature of 1, initial state and 2, final state of the gas.
Initial states:
P₁ = 743 torr
V₁ = 975L
T₁ = 30°C + 273.15K = 303.15K
P₂ = 375 mmHg = torr
V₂ = Our incognite
T₂ = -35°C + 273.15K = 238.15K
Replacing:
[tex]\frac{743torr*975L}{303.15K} =\frac{375torrV_2}{238.15K}[/tex]
V₂ = 1518Lwhat is the temperature of the liquid at vaporization (boiling/condensing)?

The temperature 30. K expressed in degrees Celsius is
A)
243°C
B)
-243°C
C)
303°C
D)
-303°C
Answer:
B
Explanation:
From Celsius to Kelvin add 273
From Kelvin yo Celsius subtract 273
Hence 30 - 273 = -243

Round the number 31.257592 to 5 significant figures.
Explanation:
Highlight the first 5 digits. You should highlight 3, 1, 2, 5, and 7 in that order.
Note the next digit after that is a 5, meaning we'll round that 7 up to 8
So 31.257592 becomes 31.258 when we round to five significant figures.
4. One of the most common predation relationships that can be seen in the Florida Everglades is between the Florida
Panther and the White Tailed Deer. Since the Florida Panther is an endangered species, what would happen to the
deer population as the panther population decreases in size?
A. The deer population would decrease.
B. The deer population would not be affected.
C. The deer population would increase indefinitely.
D. The deer population would increase and then level off.
Answer:
D
Explanation:
It would be D because it would increse yes in population because the panthers are decreasing and attacking less. But, it would still level off because there are other predators who can kill the white tailed deer. Also the panther who is endangered could still atack even though theres just a few left that does not affect them from attacking. So it would increase but it would still level off.

A wave that travels at the speed of light and consists of a combined electric and magnetic effect
Answer:
Electromagnetic waves
Explanation:
The description given is that of an electromagnetic wave.
Electromagnetic waves are propagated by the vibration of electrical and magnetic fields in a perpendicular direction to one another.
These waves generally travel at the speed of light. They are made up of magnetic and electric fields. They do no require a material medium for their propagationThey can pass through a vacuum.What does an atomic number represent in an atom? number of neutrons number of protons number of electrons number of protons and neutrons

A runner eats a snack with 375 Calories of nutritional energy. After her snack, she burns 3.16 x 10^6 joules while running
Answer:
The complete question is given below
A runner eats a snack with 375 Calories of nutritional energy. After her snack, she uses 3.16 X 106 joules while running [1 Calorie = 4184 joules).
Which of the following statements are true? Select all that apply.
A. There were 1.57 X 106 joules of energy in the snack.
B. There were 3.14 X 106 joules of energy in the snack.
C. During her run, she used 755 Calories of energy.
D. During her run, she used 189 Calories of energy.
E. The runner used more Calories while running than she consumed during her snack.
F The runner used fewer Calories while running than she consumed during her snack.
Answer: Options A, C and E are all correct options
Explanation:
From the question,
1 calorie = 4184 Joules
therefore 375 calories from the consumed snack
= (4184 x 375) J
= 1,569,000J
= 1.56 x 10⁶ J (option A is correct)
While running, she expends 3.16 x 10⁶ J. We can convert this to calories to see how much calories she expended while running
Recall 4184 Joules = 1 calorie
therefore, 3.16 x 10⁶ Joules is equivalent to
= (3.16 x10⁶/ 4184) calories
= 755.6 calories (option C is also correct)
If she consumes 375 calories from her snack but expended 755 calories during her running exercise, therefore the runner consumed fewer calories than what she expended during her exercise, hence option E is also correct
Answer: Options A, C and E are all correct options
