Answer:
Their populations will decrease because of a decrease in usable habitat.
Explanation:
Answer:
worldwide burning of fossil fuels
Explanation:
The heavy usage of the fossil fuels as energy sources for the industry has resulted in much increased emissions of CO2 in the atmosphere. It all started around 200 years ago with the Industrial Revolution. In order for the machines to function, efficient energy sources were needed, and the best thing at that time for that was the coal. Through the burning, the coal manages to release enormous amounts of CO2 into the atmosphere. After some time, the oil was discovered as well, and it started to be heavily used as well, further increasing the CO2 emissions. As the technology has been developing more and more, the demand for the usage of the fossil fuels has been increasing constantly, so there's an ever growing CO2 emissions into the atmosphere.
Answer:
(a):Valency is the measure of the capacity of an atom of a single element to react and combine with particular numbers of atoms of another element.
(b):
Valency of calcium:+2
Valency of Iron:Iron exhibits 2 valence states of +2 and +3.
Valency of hydroxl:-1
Valency of Nitrate:-1
Explanation:
<u>Answer:</u>
<em>Latest take an example to understand how </em><em>balancing of chemical reaction</em><em> is done that is assuming the reaction between iron as well as </em><em>oxygen which reacts to form rust.</em>
<u>Explanation:</u>
For this we would simply right the reactant and product that is expected. Then we would see the number of molecules of each element present on either side.
If in the reaction the element’s molecules are the same on both sides then the reaction would be correct and if not then we have to apply trial and error method to balance the equation such that the number of molecules of each element is equal on both sides of the reaction.
How an atom reacts chemically depends on how willing it is to share electrons with others.
It’s electrons
