Yes! You're correct! Hope this helps! :D
<span> rate 3/1= square root of 32/x
square both sides
9/1=32x
x = 32/9
= 3.6
Must be He
molar mass =4

The first thing you need to know about this problem is that delta total = delta Hf products - delta Hf reactants.
Delta total = (4*NO + 6*H2O) - (5*O2 + 4*NH3)
Delta total = [(4*91.3 kJ/mol) + (6*-241.8 kJ/mol.) - (5*0 kJ/mol.) + (4*-45.9 kJ/mol.)
Products= 4*(365.2)+(-1450.8)=-1085.6 kJ
Reactants=4*(-45.9) + 5*(0)= -183.6 kJ
Delta Rxn= (-1085.6 kJ) - (-183.6 kJ) =-902.0 kJ
Her model allows Christina to gather data about wave P, since she created a model.
Answer: To be accurate, it must be able to make measurements that are close to the actual value.
