I believe it would weigh less if it’s blown up with helium because helium is lighter than air
Answer: The mole ratio of hydrogen to nitrogen is 3 mole: 1 mole, 3:1
Explanation:
•Mole ratios are determined using the coefficients of the substances in the balanced chemical equation. •Each coefficient represents the number of mole of each substance in the chemical reaction.
•The mole ratio can be determined by first writing out a balanced chemical equation for the reaction.
For this reaction the balanced chemical equation is
N2(g) + 3H2(g) ----> 2NH3(g)
1mol:3mol : 2mol
From the equation we can see that 1 mole of N2(g) reacts with 3 moles of H2(g) or 3 moles of H2(g) react with 1 mole of N2(g) to produce 2 moles of NH3(g).
Therefore, the mole ratio of hydrogen to nitrogen is 3 mole: 1 mole, 3:1
Answer:
Explanation:
Space exploration technology has helped us explore the Moon and see images of far off galaxies.
Space technology may help us inhabit another planet or live in space in the future.
These are the correct statements
Not sure but it might be A or B
I think cathode should be silver or gold
you can use silver nitrate solution or mercury nitrate solution
