Answer: 12 L fluorine gas at STP can be collected from the decomposition of 90.7 g of 
Explanation:
The balanced decomposition reaction is shown as
moles of 
According to stoichiometry:
2 moles of gives = 3 moles of flourine gas
Thus 0.36 moles of gives = 
of flourine gas
Using ideal gas equation :
P = pressure of gas = 1 atm ( at STP)
V = Volume of gas = ?
n = moles of gas = 0.54
R = gas constant = 0.0821 L atm/Kmol
T = temperature = 273 K ( at STP)
Putting the values we get :
Thus 12 L fluorine gas at STP can be collected from the decomposition of 90.7 g of
Answer:
Initial Velocity is when movement begins. When a body is at rest, the initial velocity is at 0 m/s.
Explanation:
Initial Velocity is the velocity at time interval t = 0
Answer:
Aluminum + Nickel(Ii) Nitrate = Nickel + Aluminum Nitrate
Explanation:
Well they buy food then they cook it then they eat it
NaBr < H3O+1 = OH-1 < Na^+1 = Br^-1 < H2O
<span>Least is NaBr (100% dissolved so no NaBr remains, only Na^+1 and Br^-1 </span>
<span>H2O yields 10^-7 M H3O^+1 and 10^-7 M OH^-1 (Kw = 1x10^-14 = [H3O+][OH-] </span>
<span>Na^+1 and Br^-1 will bothe be 0.1 M </span>
<span>H2O is slightly less that 1000 g / L in a 0.1 M NaBr solution, so its concentration is about 55.5 M</span>
