But I want you to do in this video is appreciate what at itsĮssence chemistry is all about. And all of these things areĪ big part of chemistry. Of the different molecules that can be depicted different ways. Things will react together to form other things.
Some of them boiling and changing colors. Working on a bench with the different vials Here some picture of what most people associate Do you feel the food is too cheap or too expensive? What does go into the process of producing food that affects its price? You buy food that you eat every day and pay for it. Well, that's just one example but we could go on like that forever.
How will you regulate the price of your potatoes in those cases? If you collect them by hand, you might save some money but you will lose more time and maybe still have less crop. How will you get rid of them? Will you collect potato beetles by hand or use pesticides? If you buy pesticides that will cost you more, but that will also affect the quality of your potatoes. Will that price be affordable to most people? To whom will you sell your potatoes? What type of soil do potatoes prefer? If you buy a more fertile arable land, will you be able to grow more potatoes with less expenses? There are pests too, they might eat seedlings, leafs, tubers. Have you ever grown potatoes? Do you know how much money you need to invest to grow one kg of potatoes? You can make it cheaper if you don't use fertilizers, but how will that affect your crop? Will you get less potatoes? Does it pay off to buy fertilizers or not? At what cost will you sell your potatoes? Obviously, you can't sell them for the same amount of money you've invested to grow them, you need to earn something too. Even nowadays there are many examples of biology influencing economics.
Back in the days of feudalism when arable land was the most valuable possession and the main source of income, knowledge about plants and how all the biotic and abiotic factors affect their growth were essential. In this video, we will discuss the trends in the properties of group-17 elements, such as the negative electron gain enthalpy, oxidation states, oxidising power of halogens etc.Ġ1:27 - Trends in the atomic properties like atomic size, ionisation enthalpy and electronegativity.Ġ1:32 - Trends in the negative electron gain enthalpyĠ4:31 - Trends in the oxidising power of halogens.Did you notice both economics and ecology have the same prefix, eco- ? It is derived from Greek word οἶκος (oikos) which means house or home.
