Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. balance the equation for the synthesis of cryolite. equation: al2o3 (s) + naoh (l) + hf (g) -> na3alf6 + h2o (g) al2o3(s)+naoh(l)+hf(g)⟶na3alf6+h2o( g) if 13.4 kg of al2o3(s), 55.4 kg of naoh(l), and 55.4 kg of hf(g) react completely, how many kilograms of cryolite will be produced?

Explanation:

1. First balance the equation for the synthesis of cryolite:

2. Find the limiting reagent between the and

- First calculate the number of moles of each compound using its molar mass and the mass that reacted completely:

- Divide the number of moles obtained between the stoichiometric coefficient of each compound in the chemical reaction:

The is the limiting reagent because it has the smallest number.

3. Find the mass of cryolite produced:

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

the answer would be c
