Answer:
One way to find out is to change “passive mass” - the dirt and rocks of Earth - and convert it into “active mass” - add energy “E” to it. If we increase the energy “E” we will increase its mass. The key is, how do you turn “passive mass” into “active mass” by adding energy “E” to the “passive mass”? After all, isn’t “passive mass” of the Earth just the dirt and rocks that make up the planet?
Explanation:
Answer:
for the cellular respiration the human body needs 1.424 E21 molecules of glucose
Explanation:
mass glucose = 24 g
∴ Mw glucose = 180.156 g/mol
∴ 1 mol ≡ 6.022 E23 molecules
⇒ mol glucose = (24 g)×(mol/180.156 g) = 0.1332 mol glucose
⇒ molecules glucose = (0.1332 mol glucose)×(6.022 E23 molecules/mol)
⇒ molecules glucose = 1.424 E21 molecules
Answer:
But it is not used as domestic fuel, due to several reasons : Hydrogen is not easily available and cost of production is high Unlike other gases, hydrogen is not readily available in the atmosphere. It requires processes like electrolysis of water for its production. This is a very costly process and time consuming.
Explanation:
6.5 is slightly acidic - so the answer is B.
