Answer
and
Explanation:
All the energy in oil, gas, and coal originally came from the sun, which is captured through photosynthesis. The same way that we burn wood to release energy that the trees capture from the sun, we burn fossil fuels to release the energy that ancient plants had captured from the sun.

Answer:
Indirect relationship
Explanation:
Mathematical relationship between two variables which can be expressed by an equation in which the product of two variables is equal to a constant is <u>indirect relationship</u> Eg:
Where k is the constant of variation. For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5(2) = 10. ... Thus, the equation describing this <u>indirect</u><u> </u><u>relationship</u> is xy = 10 .
POH+pH=14
pH=14-pOH=14-3.53=10.47
pH=-log[H⁺]
[H⁺]=10^(-pH)
[H⁺]=10^(-10.47)=3.4*10(^-11)
His work foreshadowed the periodic table. He tried organizing elements into triads, a set of 3 elements with similar properties. In each triad the mean of the lightest and heaviest atomic weight equaled to approximately the atomic weight of the middle element.
