In the article, Invasion of the Periodical Cicadas, why do scienctists believe that cicadas only reproduce every 13 or 17 years? Explain your answer with evidence from the text.
Hi, you've asked an incomplete question. However, I assumed you are referring to the article found on the Scientific American website.
Explanation:
Remember, according to that article we are told that scientists notice that these insects have a long nymphal (immature form before becoming adults) stage, one that can last up to 13 to 17 years on the ground before they leave the ground looking for mating partners.
Because it is only after mating occurs at this point that their eggs are laid, that is why scientists believe that cicadas only reproduce every 13 or 17 years.
The formula for one molecule of sucrose is shown below.
C12H22011
How many atoms in all are in one molecule of sucrose?
Answer:
45
Explanation:
There are 12 Carbons
There are 22 Hydrogens
There are 11 Oxygens.
I think the answer is either 0 or 45. But the wording is very sloppy. It is not really atoms that are present. There are ions.
Go with 45 but hold your nose when writing your answer.
How much energy would be required to heat 10.0 g of water at 0 degrees C to 100 degrees C,and change it into steam at 100 degrees C
Answer:
Q = 4180 J
Explanation:
Given data:
Mass of water = 10.0 g
Initial temperature = 0°C
Final temperature = 100°C
Heat required = ?
Solution:
Specific heat capacity of water is 4.18 j/g.°C.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 100°C - 0°C
ΔT = 100°C
Q = 10.0 g ×4.18 j/g.°C × 100°C
Q = 4180 J

what would happen if the
attractive forces between all of the particles
of matter on Earth were equal?
The magnitude of attractive forces between particles that compose matter determine the state of matter. Hence, if all particles of matter on earth have equal attractive forces, only a single state of matter (solid, liquid or gas) will exist on earth.
Matter exists in three states;
SolidLiquidGasIn solids, there exists the greatest magnitude of attractive forces between particles.
There are weaker inter-molecular attractive forces between liquid particles. However, inter molecular attractive forces are almost non-existent in gases.
The reason for the existence of different states of matter on earth is difference in magnitude of inter molecular attractive forces in each state of matter.
If all particles of matter possess equal attractive forces, only one state of matter will be found on earth; either solid, liquid or gas.

Which describes how rubbing fur on a rubber rod makes the rod negatively charged. Select one: A. Electrons move from the fur to the rubber rod. B. Electrons move from the rubber rod to the fur. C. Protons move from the rubber rod to the fur.
Answer:
A
Explanation:
Rubbing fur on a rubber rod results in the rod becoming negatively charged as a result of the movement of electrons from the fur to the rubber rod.
The process is called triboelectric charging. When the two substances are rubbed together, their atoms come into close proximity with each other and their electron clouds interact with the fur losing electrons to the rubber due to the fact that the atoms of the rubber have higher affinities for electrons than the atoms of the fur. Hence, the fur becomes positively charged while the rubber becomes negatively charged.
How many moles of cesium carbonate will be produced when 5.34 moles of cesium reacts with iron (III) carbonate? (You must write and balance the formula equation!)
Answer:
2.67 moles of cesium carbonate (Cs2CO3).
Explanation:
We'll begin by writing the equation for the reaction. This is illustrated below:
Cs + Fe2(CO3)3 —> Cs2CO3 + Fe
The above equation can be balance as follow:
There are 2 atoms of Fe on the left side and 1 atom on the right side. It can be balance by putting 2 in front of Fe as shown below:
Cs + Fe2(CO3)3 —> Cs2CO3 + 2Fe
There are 3 atoms of C on the left side and 1 atom on the right side. It can be balance by 3 in front of Cs2CO3 as shown below:
Cs + Fe2(CO3)3 —> 3Cs2CO3 + 2Fe
There are 6 atoms of Cs on the right side and 1 atom on the left. It can be balance by putting 6 in front of Cs as shown below:
6Cs + Fe2(CO3)3 —> 3Cs2CO3 + 2Fe
Thus, the equation is balanced.
From the balanced equation above,
6 moles of Cs reacted with 1 mole of Fe2(CO3)3 to produce 3 moles of Cs2CO3.
Finally, we shall determine the moles of cesium carbonate (Cs2CO3) produced by the reaction of 5.34 moles of cesium (Cs). This can be obtained as follow:
From the balanced equation above,
6 moles of Cs reacted to produce 3 moles of Cs2CO3.
Therefore,
5.34 moles of Cs will react to produce = (5.34 × 3)/6 = 2.67 moles of Cs2CO3.
Thus, 2.67 moles of cesium carbonate (Cs2CO3) were produced from the reaction.

Explain why both a power source (like a battery) and a complete circuit are necessary for an electromagnet to function.
this is science homework by the way, please help me with it:)
Answer:
Electromagnets are only functional when electricity is passing through them. In other words, they only create a magnetic field when there is an electric current flowing.
A power source like a battery is therefore necessary to supply the electric current necessary for the magnet to work however, it will not work unless the circuit is closed as electricity cannot not flow in an open circuit because current needs to be able to flow from one end of a power source to the other end.

Learn how factors, such as exposure to the atmosphere, the composition of rock and climate affect the rate of weathering. Weathering is the mechanical or chemical process by which rocks are broken down. The weathering that happens to rocks can be understood by relating it to the digestion of a chocolate chip cookie
One of the factors that affects the rate of weathering is exposure to the atmosphere. ... Another factor that affects the rate of weathering is the composition of rock. Rocks are composed of minerals, which are solid substances found within rocks that have their own distinct chemical composition.

Which of the following is the best way to model the process of weathering?
Using a fan on a pile of sand causing the sand to move into a pile in a new location.
Using a ramp to dump sand at the bottom causing the sand to pile up.
Using a watering can sprinkle water onto sand causing the sand to move to a new location.
Filling a glass bottle with water and allowing it to freeze causing the bottle to break.
The best model of weathering is using a fan on a pile of sand causing the sand to move into a pile in a new location.
Weathering refers to the gradual breakdown of a rock due to the agents of denudation. The agents of denudation could be physical, chemical or biological.
The breakdown of rocks leads to the formation of soil. The closest model to the weathering of rock is using a fan on a pile of sand causing the sand to move into a pile in a new location.
The pile represents the rock which is being broken down as the fan blows the pile and it settles on a new location.
