The volume of Hydrogen gas : 24 L
<h3>Further explanation</h3>
Given
16 L Ammonia(NH₃)
Required
The volume of Hydrogen gas
Solution
Reaction
N₂ + 3H₂ ⇒ 2NH₃
Avogadro's hypothesis:
In the same T,P and V, the gas contains the same number of molecules
So the ratio of gas volume will be equal to the ratio of gas moles
V₁/n₁=V₂/n₂
From the equation, mol ratio of H₂ : NH₃ = 3 : 2, so volume of H₂ :
= 3/2 x volume of NH₃
= 3/2 x 16 L
= 24 L
Answer: <u>Carbohydrates, proteins, lipids, and nucleic acids. </u>
Explanation: The main four basic substances are carbohydrates (elements carbon (C), hydrogen (H), and oxygen (O), lipids, proteins, and nucleic acids. Which all happen to be organic compounds as well.
Hope this helps! :)
Answer: 3.0 moles of water 
are needed to react with a mole of 3.0 of Na
Explanation:
The balanced chemical reaction of sodium with water is as follows:
According to stoichiometry:
2 moles of sodium 
reacts with = 2 moles of water
Thus 3.0 moles of sodium reacts with = 
moles of water
3.0 moles of water are needed to react with a mole of 3.0 of Na
Answer :
Heating takes place during the process of Evaporation, Melting, Sublimation.
Cooling takes place during the process of Freezing, Condensation, Deposition.
Explanation :
Heating : It means thermal energy releases.
Cooling : It means thermal energy absorbs.
Evaporation : It is a type of vaporization process in which a liquid changes into gas phase by providing heat.
Melting : It is a process in which a solid changes into liquid phase by providing heat.
Sublimation : It is a process in which a solid changes directly into gas phase without passing through a liquid phase.
Freezing : It is a process in which a liquid transform into a solid phase at low temperature.
Condensation : It is a process in which a water vapor(gas) changes into liquid state at low temperature.
Deposition : It is a process in which a gas transforms directly into a solid phase without passing through a liquid phase.
Answer:
Generally speaking, as the human population grows, our consumption of natural resources increases. More humans consume more freshwater, more land, more clothing, etc. Scientific and technological innovations mean that we are improving our efficiency at using and harvesting natural resources.
