The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale Figure 1 It is neither acidic nor basic, and has a pH of 7.0 Anything below 7.0 is ranging from 0.0 to 6.9)is acidic and anything above 7.0 from 7.1 to 14.0 is alkaline.
Develop cost efficient methods to use solar energy
increase the use of wind power
reduce the use of coal and oil
Answer:
Explanation:
a ) 15( ft)³ = 15 ( 12 inch )³ = 15 x 12 x 12 x 12 (inch)³ = 25920 (inch)³
=25920( 2.54 cm)³ = 25920 x 2.54 x 2.54 x 2.54 cm³ =424752.7 cc
424752.7/1000 litre = 424.75 liter
424.75 liters cost 1.30 dollars
1 liter costs 1.3/424.75 = 3.06 x 10⁻³ dollars.
So rate
= 3.06 x 10⁻³ dollars/liter
b ) one liter of water takes 0.304 ft³ of gas
2.1 liter will take 0.304 x 2.1 = 0.6384 ft³ of gas
cost = 1.3 x .6384 / 15 = 0.055328 dollar = 55.33 x 10⁻³ dollar.
