Answer:
2 moles NH3 = 1 mole of N2
3 moles of H2 = 1 mole of N2
3 moles of H2 = 2 moles of NH3
Explanation:
The balanced equation for the reaction is given below:
N2 + 3H2 —> 2NH3
From the balanced equation above,
1 mole of N2 reacted with 3 moles of H2 to produce 2 moles of NH3.
Thus, we can say that:
1 mole of N2 = 3 moles of H2
1 mole of N2 = 2 moles of NH3
3 moles of H2 = 2 moles of NH3
Thus, considering the options given above, the right answers to the question are:
2 moles NH3 = 1 mole of N2
3 moles of H2 = 1 mole of N2
3 moles of H2 = 2 moles of NH3
Answer:
Becuase they can go through mountains and hills, they curve of of those.
Here are the answers in order:
1. During a physical change the substance changes physically.
2. The law of conservation of mass is a law stating the conservation of mass cannot be higher than 46mg or lower than 32mg.
3. A hypothesis is a guess that you make before completing a science experiment, it can be considered a law because it is important to know why you are making the guess.
4. During a chemical change the mass is changing colors. This is a representation of a chemical change.
5. Oil is a non-renewable resource, so it cannot demonstrate the conservation of mass.
6. When the color of the substance has changed or when it explodes.
7. Reactants are the objects that react when in a chemical change.
8. If you follow the rule of not going higher than 46mg and not lower than 32mg then it will automatically follow this law.
