1 oxygen 1 hydrogen hydrogen peroxide I think
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.
The positive effect of using chemistry is the generation of energy without fossil fuels.
Chemistry is the branch of science that deals with the study of the nature, properties and composition of matter as well as the changes that matter undergoes. Chemistry has really contributed positively to the advancement of the society.
