2NH3 -> N2+ 3H2 - If 2.5 moles of N2 reacts are formed, how many moles of NH3 (ammonia) are decomposed?
- If 6 moles of NH3 (ammonia) are decomposed, how many moles of H2 gas reacts completely?
- If 9 moles of H2 gas is formed, how many moles of N2 are also formed?

Mg-26 and mg-24 are pair of isotopes. isotopes are defined as atoms of the same element having same atomic number but different mass number. i hope that was .

The water cycle increase the water content in the earth atmosphere

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
