Answer:
668.9K is the final temperature
Explanation:
The change in entropy, ΔS, of an ideal monoatomic gas is obtained using the equation:
ΔS = n*Cv*ln (T2/T1)
<em>Where ΔS is change in entropy = 200J/K</em>
<em>n are moles = 20.0mol</em>
Cv is 3/2R for an ideal monoatomic gas (3/2*8.314J/molK)
T2 is final Temperature and T1 initial temperature = 300K
Replacing:
ΔS = n*Cv*ln (T2/T1)
200J/K = 20.0mol*3/2 *8.314J/molK*ln (T2/300K)
0.80186 = ln (T2/300K)
2.23 = T2 / 300K
<h3>668.9K is the final temperature</h3>
Explanation:
Atomic number of carbon is 6. So, 4 valence electrons are present.
Therefore, it can form 4 covalent bonds with varying bond angles by sharing its valence electrons.
Catenation is also an important property of carbon. Catenation is bonding with atoms of same element. Carbon skeleton can be formed in any direction and can vary in length, branching, and ring structure.
Elements required for making most of the molecules in living organisms are:
C, H, N, O, P and S
Carbon easily form covalents with other 5 elements.
These properties make carbon most versatile building blocks of the molecules used by living organisms.
Answer: light, chlorophyll,
Explanation:
Light energy drives the synthesis of carbohydrates from corbondioxide and water with the generation of oxygen. Meanwhile chlorophyll helps in the capturing of this light energy.
