Balancing Equations/RAM
« on: May 17, 2010, 01:00:31 PM »
QUESTION ONE

Write balanced equations to represent the formation of the following compounds, starting with T2 or T20

NT3: 3T2+N2-->2NT3

NaOT: i don't know how to do this one

could some one help me out please?

T2O + 2NA ---> 2NaOt?

QUESTION TWO

Chlorine exists as two isotopes, Cl-35 and Cl-37. The ram of chlorine is 35.45 Calculate the percentage abundance of each isotope.

Well, apart from the errant capitalisation, this looks fine to me

QUESTION TWO

Chlorine exists as two isotopes, Cl-35 and Cl-37. The ram of chlorine is 35.45 Calculate the percentage abundance of each isotope.

If you have x % of  35Cl, how much 37Cl do you have? What will the atomic mass be?

Though this is not balanced yet. What would the reaction be if you simply had protiated water, H2O ?

2T2O + 2Na = 2NaOT + T2
