Answer:
Explanation:
local grocery stores have started to use reusable bags made of a thicker and more recyclable plastic in order to be more environmentally friendly. However, often times when I or my family goes to the grocery store, we forget our reusable bags and end up buying even more bags every time we forget them. Because humans are, from what I can tell, forgetful creatures, it is likely that many other people experience the same issue. This causes me to wonder how much more plastic is being used to make the reusable bags in order to meet the demands of forgetful customers, and how many of these plastic bags are accidentally ending up in our environment when people throw extras away or simply lose them. This relates to the findings of the study in the sense that all of those “biodegradable” bags are ending up in the environment and still causing harm, even though they were designed to eliminate it, just like how the reusable grocery bags could potentially be adding more plastic to the environment when they were designed to eliminate that risk. These situations show how even though there are new and innovative designs that say they can help our problems, we can’t become blind to the fact that we haven’t completely solved them yet.
Answer:
The heat of vaporisation of methanol is "3.48 KJ/Mol"
Explanation:
The amount of heat energy required to convert or transform 1 gram of liquid to vapour is called heat of vaporisation
When 8.7 KJ of heat energy is required to vaporize 2.5 mol of liquid methanol.
Hence, for 1 mol of liquid methanol, amount of heat energy required to evaporate the methanol is =
= 3.48 KJ
So, the heat of vaporization
Therefore, the heat of vaporization of methanol is 3.48KJ/Mol
C2H2
= 2:2 = 1:1 ratio
CH4
= 1:4 ratio
C4H6
= 4:6 = 2:3 ratio
