Given the following equation: Na2SiO3 + 8HF = H2SiF6 + 2 NaF + 3H2O

How many moles of HF are needed to react with 0.6000 mol Na2SiO3
a. 3 mol HF
b. 4.8 mol HF
c. 8 mol HF
d.1 mol HF

1.from liquid state to gaseous state is evaporation 3.solid to liquid is melting 5. solid to gaseous state is sublimation 6. gas to solid state is decomposition 7. a change of state is known as the states of matters

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess

Bis the answerhope it !
