CH4 Methane which is the prototypical organic molecule and the others are chemical not sure about water
Answer is: A. food chains.
Plants convert solar energy into the chemical energy of sugars (food).
Solar energy is stored in chemical bonds of sugars (glucose for example).
The overall balanced photosynthesis reaction:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
In carbon dioxide, carbon has oxidation number +4 and in photosynthesis carbon gain electrons (solar energy), so his oxidation number is lowered (reduced). Light energy is transformed into chemical energy, that is stored in carbohydrate molecules (glucose), which are synthesized from carbon dioxide and water.
I’m pretty sure it’s indictment
<span>Molality(m) or molal concentration is a measure
of concentration and it refers to amount of substance in a specified amount of
mass of the solvent. Used unit for molality is mol/kg which is also
sometimes denoted as 1 molal. It is equal to the moles of solute (the substance
being dissolved) divided by the kilograms of solvent (the substance used to
dissolve).</span>
Molarity(M) or molar concentration is also a
measure of concentration and represents the amount of substance per unit volume
of solution(number of moles per litre of solution. Used unit for molarity is
mol/L or M. A solution with a concentration of 1 mol/L is equivalent to 1 molar
(1 M).
Molality is preferred when
the temperature of the solution varies, because it does not depend on
temperature, (neither number of moles of solute nor mass of solvent will be affected
by changes of temperature), while molarity changes as temperature changes(volume
of solution changes as temperature changes).
What? I’m confused???????????????????????????
