Answer: 2 mol of NaOH
Explanation:
The balanced chemical equation for the reaction is:
Na2O + H2O --> 2NaOH
Looking at this, we can see that 1 mol of Na2O will react with 1 mol of H2O to produce 2 mol of NaOH
Answer:
2.853881279 years
Explanation:
I multiplied 365 times 24 to get 8760 hours in a year. I then multiplied this by 60 to get 525600 seconds per year. Lastly, I divided 1500000 by 525600 in order to get the answer. Hope this helps!
False
Explanation:
The force in a magnet is not a magical superpower, it is a magnetic force field produced by interacting domains in magnetic materials.
- magnets attracts or repels other substances especially metals to themselves.
- magnets carry force fields around them that starts at the north pole and enters through the south pole.
- the region where the magnetic effect is felt is called the magnetic force field of the magnet.
