Answer:

(C) The average molecular speed of ethane is equal to the average molecular speed of propanol.

Explanation:

When dealing with gases, you know that the temperature and speed are related. When held at a constant temperature, the speed is also held constant. We also know that ideal gases behave the same despite their identities.

What do the conclusions tell about the experiment?
Blababa [14]

Answer:

Option C

Explanation:

When you perform a experiment to test your hypothesis (your educated guess on what you think will happen) you complete trials to find data that is reliable and valid so you are only getting the best possible results. After you complete the experiment you write your conclusion which is when you take the data and you say if the data supported your hypothesis, if you did guess correctly at the beginning of the experiment. Which means the answer is option C "the conclusions tell why the data support or reject the hypothesis."

Hope this helps.

Brief report on the carbon cycle
Tamiku [17]

Answer:

Explanation:

The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.

What is the difference between a physical and chemical change? From what I know a chemical change modifies the atoms of an objec
blsea [12.9K]
Physical change: a change in which no new substances are formed. the form of the substance is changed but not it's chemical composition (ice melting, bread toasting)

chemical change: any change that results in the formation of new chemical substances. this type of change modifies molecules and atoms by making and breaking the bonds between atoms! (iron rusting, gas burning)

so basically a physical change just changes the appearance of a substance, but a chemical change changes the makeup on a molecular level. i hope this helps you out!

How is bacteria on mars counted as life but a heartbeat on earth not?
Sever21 [200]

Answer:

It is considered life, but that doesn’t have to do much with abortion.

We kill things all the time. Unless you are vegetarian, lots of animals are killed to give you meat. Even if you are, you’ll probably swat a mosquito that’s trying to bite you. And what about the bacteria inside your body that are constantly killed to keep you healthy?

The question is how much this life is worth. This becomes more a question of ethics, but I think we can all agree a human life is worth a lot. So killing humans is wrong. What about somewhat intelligent animals? Well, killing them just for the fun of it or because you can is wrong as well I think.Most people think that’s okay, although some people will disagree and become vegetarians.

Insect life is worth less, and killing an insect is seen by most people as okay as long as you have even a small reason for it (like being irritated by a buzzing fly).

And all the way on the bottom are bacteria. They are not conscious, even though alive.

Sorry about the first answer. I didn't look at the question carefully since I wasn't wearing my glasses.

If this doesn't help than I'm sorry.

Which of the following conversion factors would be used to calculate the number of moles of Cl2 produced if 11 moles of HCl were
MissTica

<u>Answer:</u> The moles of chlorine gas produced is 5.5 moles

<u>Explanation:</u>

We are given:

Moles of HCl = 11 moles

For the given chemical reaction:

4HCl+O2\rightarrow 2Cl_2+2H_2O

By Stoichiometry of the reaction:

4 moles of HCl produces 2 moles of chlorine gas

So, 11 moles of HCl will be produced from \frac{2}{4}\times 11=5.5mol of chlorine gas

Hence, the moles of chlorine gas produced is 5.5 moles
