Answer what there is no question
B because A is for radios of course and C is thermal energy and D is radioactive
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:
1 mol of CH₄ will contain greatest mass of the oxygen i.e 4 grams
Explanation:
Given;
1 mol of CH₄
0.6 mol of C₆H₆
0.4 Mol of C₃H₈.
Now,
moles = Mass / Molar mass
Thus,
for 1 mol of CH₄
1 = mass / ( 12 + 4 × (1) )
or
mass = 16 grams
now,
16 grams of CH₄ contains 4 grams of hydrogen
and, for 0.6 mol of C₆H₆
0.6 = Mass / ( 12 × 6 + 6 × 1)
or
Mass = 46.8 grams
Now,
78 grams of CH₄ contains 6 grams of hydrogen
thus,
46.8 grams of CH₄ will contain = (6 / 78) × 46.8 grams of hydrogen
or
46.8 grams of CH₄ will contain = 3.6 grams of hydrogen
and, for 0.4 Mol of C₃H₈
0.4 = mass / (3 × 12 + 8 × 1)
or
Mass of 0.4 Mol of C₃H₈ = 17.6 grams
Now,
44 grams of C₃H₈ contains 8 grams of hydrogen
thus,
17.6 grams of C₃H₈ will contain = ( 8 / 44 ) × 17.6 grams of hydrogen
or
17.6 grams of C₃H₈ will contain = 3.2 grams of hydrogen
Hence,
1 mol of CH₄ will contain greatest mass of the oxygen i.e 4 grams
