The correct answer is the first option. Each level of energy transfer in an ecosystem or food chain is called a trophic level. It comprises organisms that share the same function in the food chain in relation to the primary sources of energy.
Answer:
4C + S8 ------> 4CS2
Coefficients are 4,1,4 respectively
Among the given mediums, Vaccuum is the best thermal insulator to reduce the transfer of thermal energy by radiation as there will be no air particles which carries heat from one place to other. Hence, Option (D) will be the correct option
<h3>What is Heat radiation ?</h3>
Heat Radiation refers to the transfer of heat from a hot body to cold body directly, without heating the medium between two bodies.
Vaccum does not have any particles in it. Thus, there will be no transfer of heat through it.
The best example of it is thermous flask in which vaccuum inside thermous flask reduces the transfer of energy through it.
Hence,Among the given mediums, Vaccuum is the best thermal insulator to reduce the transfer of thermal energy by radiation as there will be no air particles which carries heat from one place to other. Thus, Option (D) will be the correct option

Answer:

Explanation:
Since you are balancing the equation you need to have equal amounts of each element on each side. Right now there is 2n and 2o on one side, and on the other 2n and 1o. Although the number of n's on each side is equal the number of o's are not. First I balance the number of oxygen's on each below, but doing that made the number of nitrogen's unbalanced. So then I balanced the nitrogens in step 2.
__N2+ __O2 = __N2O
1. __N2+ __O2 = 2 N20
2. 2 N2 + 1 O2 = 2 N2O
