Which are the two kinds of shaped molecules that Hydrocarbons can have?

# data[].attributes.body
Today I learned that fossil fuels are natural resources, such as coal, oil and natural gas, containing hydrocarbons. These fuels are found on Earth over millions of years and produce carbon dioxide when burned. Today, fossil fuels provide just over 85% of energy needs worldwide: at this rate, oil contributes 40%, coal 26% and gas natural for 23%. A further 7% comes from nuclear energy.

What struck me most about the lesson was the group game where everyone had to answer the question and if it was wrong you had to go back.
-while for the video I really liked the part where he explained what a fossil and which of the fossil fuels were most used.
fuel was

If there were no more oil, which energy source could be used?

# data[].attributes.body
I liked working in a group. The video was very interesting and I Learned new words in English.

# data[].attributes.body
What will we use when the fossil fuel runs out? Can we find another source of energy that has the same effects but it is inexhaustible?

# data[].attributes.body
I learned more things than I known before about hydrocarbons. For example I learned new words to describe them, how they are produced and where is the mayor concentration of them.

# data[].attributes.body
I was absent but my group and I worked well together to find the correct answers to the questions. The video was clear and explained its contents well.

# data[].attributes.body
I learned, in addition to new English terms, the role, composition and history that fossil fuels have.

# data[].attributes.body
It was a very interesting and informative video about how oil is formed and how it is composed.

# data[].attributes.body
when the oil is finished which energy source will be better to use?

# data[].attributes.body
It is possible to discover substances similar to hydrocarbons but with a different environmental impact?

# data[].attributes.body
it was fun to work in a group, I was also impressed when in the video he explained what oil is made of

# data[].attributes.body
from this video I learned how important oil is for the world, how oil is formed and I learned new English terms

# data[].attributes.body
Is it possible to find a way to produce this substances without harm the planet?

# data[].attributes.body
I learned a lot of english chemistry words that i didn’t know. For example know how hydrocarbons are formed.

# data[].attributes.body
it was very nice working in groups and find out new english words.

# data[].attributes.body
Is it possible to find other solutions to replace fossil fuels and reduce pollution in our world?

# data[].attributes.body
Is it possible to find a way to make these substances be produced faster?

# data[].attributes.body
Can the fossil fuels that run out be replaced by something like this?

# data[].attributes.body
I learned new words in English that I had never heard before and also the function of hydrocarbons and how they affect our planet.

# data[].attributes.body
it was very nice to know new words and new things about chemistry in English. It was fun working in a group and discovering new things.

# data[].attributes.body
it was very interesting to know how the hydrocarbons are formed and used.I didn’t know the history of oil I really liked to find out.

# data[].attributes.body
Is it a problem if we run out of oil since it is a non-renewable substance?

# data[].attributes.body
I learned a lot of terms in English that I didn't know before, and I also learned several things that I didn't know about oil before.

# data[].attributes.body
From this video I found it interesting how petroleum is formed and the fact of how all hydrocarbons are made from the basic components.
It also struck me how oil can be an economically important substance, but at the same time it can also be a dangerous substance.

# data[].attributes.body
I really enjoyed working in a group and learning more about topics I had only heard about.

# data[].attributes.body
How long will it take to run out of fossil fuels? and what will the world be like when they end?

# data[].attributes.body
I learned the function of hydrocarbons, the nature of fossil fuels and something more about petroleum.

# data[].attributes.body
I really enjoyed participating in this lesson, I think that these current topics are very important because they concern our world. I also liked working in group.

# data[].attributes.body
I'm wondering how the world will be when fossil fuels are finishing.

# data[].attributes.body
I learned some new English words and something more about fossil fuels.

# data[].attributes.body
I liked that the lesson was in English because, even if I have heard of this topic many times, I participated on an alternative and more interesting lesson than usual.

# data[].attributes.body
How could the production of fossil fuels be speeded up, so that they do not run out?

# data[].attributes.body
I learned new words in English thanks to this video, I learned the nature of fuels, and I enjoyed connecting the topic of energy resources with English

# data[].attributes.body
I really enjoyed  that we discovered new things about  foxil fuels, the video was also very interesting because it explains how fossil fuels and their compositions are born

# data[].attributes.body
Is it possible to find a way to make hydrocarbons less harm to the environment?

# data[].attributes.body
I learned the consequences that some compounds have on our world and in which places they are produced, I also learned new words in English related to this topic.

# data[].attributes.body
I learned how and by what they are formed, and also how many and what types exist of them. Another thing that I learned is which country produces the most.

# data[].attributes.body
How petroleum and its derivaties can be used in order to avoid polluttin  the environment?

# data[].attributes.body
I learned where and how petroleum and hydrocarbons come from in depth.

# data[].attributes.body
I learned the consequences of using hydrocarbons and which city produces them in large quantities

# data[].attributes.body
I liked working in an interactive way and especially the fact that it was done in English, because we did this argument in italian but is good also to do this and other topics in english.

# data[].attributes.body
I have learned that the things we often use, and which we cannot do without, are the very things that are bad for the environment around us and for ourselves.

# data[].attributes.body
I liked working in a group, since not many group works have been done in this period, I also enjoyed working in English as it is not often done.

# data[].attributes.body
I learned the usefulness of hydrocarbons, but also how they will affect and harm the world and consequently future generations.

# data[].attributes.body
I liked working in a group, I took part an alternative lesson and I learned new things about the topic.

# data[].attributes.body
I really enjoyed working in a group and especially in English.
The video was very interesting because it was very detailed.

# data[].attributes.body
I learned that methane, which is a gas at room temperature becomes heavy enough not to evaporate easily

# data[].attributes.body
I really liked how we worked in groups and how we learned new things and problems about the world around us, which perhaps not everyone knew.

# data[].attributes.body
The thing I liked of the lesson is the fact that we have learned the importance of hydrocarbons and the impact that these have on our planet

# data[].attributes.body
I like how we learned new things about this topic and how we process the information learned from the lesson in groups, i also like how the information is well explained in the video.

# data[].attributes.body
I learn that sometimes, the things that we need and we focus the most, are also the things that kill our planet and with him, us.

# data[].attributes.body
I liked how we learn new things about our world and listen to new things i didn't know before. I also appreciate some references about the problem that are present in this world and how is going to damage the future generations.

# data[].attributes.body
Is there a way today to generate a chemical compound similar to petroleum with our technologies (with the same uses), without having to wait millions of years to be produced?

# data[].attributes.body
I learned the usefulness of hydrocarbons, what they are, where they come from in the world and why they develop more in certain places than in others.

# data[].attributes.body
I liked it because, a group work was done and in English but above all because we saw the topic of hydrocarbons not only from a chemical point of view but how they are produced and used.

# data[].attributes.body
I appreciated the fact that the video also showed the history of oil, that oil continues to be one of the most important commodities in the economy of our times.

I learned from how oil is composed and also from other producing countries, because I knew other things.the major oil producers are the countries of the Middle East.

I would like to ask myself a question, but if this source runs out, will there be other compounds of a similar nature?
