The main chemical in the atmosphere of Venus is carbon dioxide. How does this compare with the atmosphere of Earth?
A carbon dioxide is not found in the atmosphere of earth
B carbon dioxide makes up a small part of the atmosphere of earth
C carbon dioxide is the main chemical in the atmosphere of earth
D carbon dioxide is found in the atmosphere of earth only near volcanoes
Answers
Answer:
B. Carbon dioxide makes up a small part of the atmosphere of earth
Explanation:
When you look at the air that you breathe, you will say, that you breathe Oxygen, but actually, you breathe 71% nitrogen, then 28% oxygen, then 1% of many different gases like Argon, and Carbon Dioxide. That 1% is very less compared to 100%, so that's why, hence, your answer is that carbon dioxide makes up a small part of the atmosphere of Earth.

There are different sources of fibres which can be genetically engineered for living organisms like the spider.
The fibre silk gotten from spiders are known to be the strongest, toughest materials on the Earth. But recently, engineers has designed amyloid silk hybrid proteins and produced them in engineered bacteria.
Even though these synthetically produced fibres are stronger than Kevlar, they prefer to use Kevlar because a much larger amount of silk might be needed to produce the same effect.

Which statement best identifies and explains the correct measurement?
Answers
According to accuracy concept,statement A best identifies and explains the correct measurement.
What is accuracy?
Accuracy in terms of chemistry can be defined as to how close a measurement is to the true value.There are three types of accuracy:
1) Point accuracy-It means accuracy is present at that point of scale only.It does not give any information about the accuracy of the instrument.
2)Percentage of true value--It is the accuracy which is determined by identifying accuracy of the instrument and comparing it with the measured true value.
3)Percentage of scale range- It is the accuracy which determines accuracy of the measurement.
In the given example,it is the accuracy of percentage of scale range type as the measurements are to be made within a range where the sample has to be measured.

The name of the tectonic plate that the ring of fire encircles is pacific plate.
What is tectonic plate?Plate tectonics is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago.The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century. Plate tectonics came to be generally accepted by geoscientists after seafloor spreading was validated in the mid to late 1960s.
Earth's lithosphere, which is the rigid outermost shell of the planet (the crust and upper mantle), is broken into seven or eight major plates )and many minor plates or "platelets". Where the plates meet, their relative motion determines the type of plate boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries .

Write the balanced equation for the rusting of iron in which iron reacts with oxygen to form iron(III) oxide. Phases are optional.
Answers
Answer:
1.) First thing to recognize is that it requires you to know the molecular formula for Iron(III) Oxide, which is Fe2O3. If you don't know this formula in all textbooks there is a page that has it and other compounds listed. I would encourage you to review this page and memorize the other compounds as these compounds will come up in future questions.
2.) Now we will write an unbalanced equation, keeping in mind that molecular oxygen( O2) is used:
Fe + O2 ==> Fe2O3
3.) In balancing problems, I like to always start with Oxygen. Because there are 2 oxygen atoms on the reactant side and three on the product side and we know that both of these numbers go into 6, we will use this to balance the oxygen. We will put a e in front of the molecular Oxygen and a 2 in front of the iron(III) oxide. This will balance the oxygens.
Fe + 3O2 ==> 2Fe2O3
However, notice now that the iron is still out of balance, This can be easily solved by having a 4 in front of the iron. Now everything is balanced!
4Fe + 3O2 ==> 2Fe2O3

A 1250.0 g piece of aluminum at -35.0°C receives 72.41 kJ of heat. If aluminum has a heat capacity of 0.90

AT =
°C
Answers
This problem is providing the mass, specific heat and melting point of aluminum and the amount of heat it receives in a heating process so it asks for the change in its temperature, which results in 64.36 °C.
CalorimetryIn chemistry, one can perform calorimetry calculations with the widely-known heat equation relating mass, specific heat, temperature and heat:
[tex]Q=mC\Delta T[/tex]
Thus, when having 1250.0 g of aluminum at -35.0 °C and supplying 72.41 kJ (72,410 J) of heat, we will be able to solve for the change in temperature by solving for it in the previous formula:
[tex]\Delta T=\frac{Q}{mC} \\\\\Delta T=\frac{72,410J}{1250.0g*0.90\frac{J}{g\°C} } \\\\\Delta T=64.36\°C[/tex]
Which is not as high as for it to provoke a melting change, with the correct significant figures as 0.90 do not contribute to this for being a theoretical number.

answer must have the correct number of sig figs. P =

Answers
This problem is providing the initial volume and pressure of nitrogen in a piston-cylinder system and asks for the final pressure it will have when the volume increases. At the end, the answer turns out to be 2.90 atm.
Boyle's lawIn chemistry, gas laws are used so as to understand the volume-pressure-temperature-moles behavior in ideal gases and relate different pairs of variables.
In this case, we focus on the Boyle's law as an inversely proportional relationship between both pressure and volume at constant both temperature and moles:
[tex]P_1V_1=P_2V_2[/tex]
Thus, we solve for the final pressure by dividing both sides by V2:
[tex]P_2=\frac{P_1V_1}{V_2}[/tex]
Hence, we plug in both the initial pressure and volume and final volume in order to calculate the final pressure:
[tex]P_2=\frac{2805mL*4.00atm}{3864mL}\\ \\P_2=2.90atm[/tex]

You recrystallize 2.1 g of an impure sample and recover 0.98 g. What is your percent recovery rounded to the tenths place
Answers
Answer:
c
Explanation:
The percent yield or percent recovery after recrystallization of the sample is 46.67%
What is percent yield?Percent yield is defined as the ratio of actual yield to the theoretical yield multiplied by 100. If the actual and theoretical yield are same then the percent yield is 100%.If actual yield is less than the theoretical yield then the percent yield is less than 100%.Reason of this condition arising is the incompletion of reaction or loss of sample during recovery process.
In cases where percent yield is over 100% it indicates that more sample is recovered than the predicted amount.This condition arises when there are other simultaneous reactions taking place leading to the formation of product. It can also arise if there is incomplete removal of impurities from the sample .
In the given example,percent yield or percent recovery is calculated as,
percent yield=recovered yield/recrystallized yield×100
=0.98/2.1×100=46.67%
Hence, the percent yield or recovery is 46.67%.
