Answer:
Yes!
Explanation:
Liquids & gases are poor conductors, but they can make heat (thermal energy) travel quickly from one point to another. ... ~ When waves of heat (thermal energy) travel through empty space and transparent mediums, heat transfer by radiation occurs. Solids, liquids, & gases can all be heated by radiation.

how many hydrogen atoms are there in one mole of ethanol.
How did astronomers use technology to identify characteristics of the Crab nebula? technology that detects ultraviolet light found hydrogen in the nebula technology that detects radio waves identified a pulsar at the center of the nebula technology that detects microwaves revealed the behavior of electrons in the nebula technology that detects gamma rays measured the distance of the nebula from Earth
Answer:
technology that detects radio waves identified a pulsar at the center of the nebula
Explanation:
Crab nebula(M1) is a blob-like patch which is supernova remnants as far as Constellation of Taurus is concerned.
It has apparent magnitude of 8.4 and can only be viewed by telescope. The astronomers make use of technology that detects radio waves, which identified a pulsar at the center of the nebula, this pulsar is a magnetized rotating compact star which is known with it's electromagnetic emissions.
Answer:

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 = 1518L4. 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.

What is a compound?Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are joined by ionic bond.
3)Inter-metallic compounds where atoms are held by metallic bonds
4) co-ordination complexes where atoms are held by co-ordinate bonds.
They have a unique chemical structure held together by chemical bonds .Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.

lonic bonds tend to form between two atoms with what characteristics?
Answer:Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Ionic compounds are typically neutral. Therefore, ions combine in ways that neutralize their charges.
Explanation:
Ionic bonds tend to form between two atoms with a high electronegativity difference.
Explanation:
An Ionic bond is defined as a chemical bond in which the complete transfer of electrons occurs from one atom to another.The transfer of electrons occurs from less electronegative atom to highly electronegative atomThe high electronegativity difference between the atomsCompounds with ionic bonds categorized as ionic compoundsSo, from this, we can conclude that ionic bonds tend to form between two atoms with a high electronegativity difference.

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.

10. A gas sample that has a mass of 6g occupies 400 mL at 504°C and a pressure of 600 mm Hg. Calculate the gas’s density at STP.
Answer:
51 g/mol
Explanation:
Whenever you see molar masses in gas law questions, more often than not density will be involved. This question is no different. To solve this, however, we will first need to play with the combined ideal gas equation PV=nRT to make it work for density and molar mass. The derivation is simple but for the sake of time and space, I will skip it. Hence, just take my word for it that you will end up with the equation:

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.

Then the chromosomes pair up and are pulled to opposite poles of the cell. Then, the membrane pinches (invaginates) in in preparation to make two cells (8).
Then, cytokinesis occurs, when the cytoplasm splits and two new cells are formed (oo)
