The equation is:

Code: Select all

Pd + 2 HCl + 2 HNO3 = PdCl2 + 2 NO2 + 2 H2O

Original equation:

Code: Select all

NaCl+F2=NaF+Cl2

Balancer:

Balanced equation:

Code: Select all

2 NaCl + F2 = 2 NaF + Cl2

By blowing HBr through AgNO3 solution:

Code: Select all

AgNO3 + HBr = AgBr&#40;s&#41; + HNO3

and then weighing the AgBr sediment.

i want to know this chemical reaction is correct or not
if this reaction is not correct means said correct reaction with balances
KNO3 + S + Al + BaNO3 = K2O + N2 + SO2 + Al2O3 + BaO

It is not correct!
BaNO3 is wrong, it should be Ba(NO3)2

a) zinc + lead(II) nitrate yields zinc nitrate + lead Zn + Pb(NO3)2 = Zn(NO3)2 + Pb b) sodium phosphate + calcium chloride yields calcium phosphate + sodium chloride 2Na3PO4 + 3CaCl2 = 6NaCl + 2Ca3(PO4)2 c) nitrogen + oxygen yields dinitrogen pentoxide...

How do you complete and balance a chemical equation and know what kind of reaction (dbl disp, singl disp, comb., etc.?) for instance, SO2 + H2O --> SO3 + H2O --> Ca+ H2O --> Bi(NO3)3 + H2S --> SO2 + H2O --> H2SO3 SO3 + H2O --> H2SO4 Ca+ 2 H2O --> Ca(OH)2 + H2 Bi(NO3)...

Code: Select all

2NaHCO3 = Na2CO3 + CO2 + H2O

is correct.

If a salt is formed by a strong acid and a weak base it's acidic.
If a salt is formed by a weak acid and a strong base it's basic.
For instance NaF is basic.

Please explain how to get this.

1) Compute the umber of moles of oxygen:
n(O) = n(V2O5) * 5

2) Compute mass of oxigen:
m(O) = molar mass of oxygen * n(O)

For molar mass of oxygen use: http://www.webqc.org/mmcalc.php

Please explain in detail how to get to the anwser

32.06 * 6.022E23 = 1.931E25

Please explain how you got the anwser

1) Compute the number of moles of gold. n = 49.5g / (molar mass of gold)
2) Compute mass of silver n * (molar mass of silver)

Hope this helps
