Submit Answer

Answers

Answer 1

Answer: 600K and 50kPa

Explanation:

Answer 2

600k as well as 50kPa since the pressure seems to be the lowest as well as the temperature is the greatest throughout this situation.

Under high temperatures and low pressures, actual gases behaved like ideal gases. such as the rule

[tex]PV=nRT[/tex]

Even though at high temperatures, the kinetic energy of such gas particles surpasses the intermolecular attractive forces, — in other words this same potential energy of something like the molecules (gaseous).

Thus the above answer i.e., "option 4" is right.

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.

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

Answers

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

Answers

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.

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!)

Answers

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.

what would happen if the
attractive forces between all of the particles
of matter on Earth were equal?

Answers

Either everything would solid (strong attractive force), liquid or gas (weaker attractive force). Everything would be the same matter

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;

SolidLiquidGas

In 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.

if one species of rabbit, the gene for brown fur ( B) is dominant, while the gene for black fur ( b) is recessive. One rabbit has the dominant allele for brown fur and the recessive allele for black fur. Another rabbit has two recessive alleles. If the two rabbits have offspring, what are the odds of one of the offspring having brown fur?

Answers

Answer:

1/2

Explanation:

According to this question, the gene coding for fur color in rabbits contains two alleles viz: alelle for brown fur ( B) is dominant, while the allele for black fur ( b) is recessive. This means that an heterozygous rabbit (Bb) will have brown fur.

Based on the question, one rabbit has the dominant allele for brown fur and the recessive allele for black fur i.e genotype Bb, another rabbit has two recessive alleles i.e. genotype bb. If these two rabbits cross i.e. Bb × bb, the proportion of the offsprings produces will have Bb, Bb, bb and bb genotype.

Bb is dominant, hence, 1/2 of the offsprings will be brown furred.

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.

Answers

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.

A population of panthers lives in the southeastern United States. Over 50 years, the size of the panther population in the region increased. What best explains the increase in the size of the panther population?

Answers

Explanation:

Because the panthers live in the southeastern region of the United states they have increased in population in that region. They have been able to gain more food and have adapted more to there environments. Which allows to increase and reproduce more. That is why the Panthers in the southeastern United states have increased In population.     I hope this works for you and that it helps. I don't mind helping someone who has a question! From, me.

A population of panthers lives in the southeastern United States. Over 50 years, the size of the panther population in the region increased. More panthers were born than died explains the increase in the size of the panther population.

What is the largest panther in the world?

The jaguar, also known as the panther, tigre, or onza, is the world's largest and most powerful cat. Human activities endanger this cat, as they do the Florida panther (Puma concolor).

Because the anteater population will have fewer energy storage molecules available due to the smaller ant population, the anteater population will reproduce less.

Panthers can be found in the southeastern United States. The region's panther population has grown over the last 50 years. Because no animal eats panthers, the panther population is always growing.

Thus, More panthers were born than died explains the increase in the size of the panther population.

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.
