Answer:
tin (IV) oxide octahydrate contains 8 part water
What is the percent composition of water found in tin (IV) oxide octahydrate?
Answer:
calcium to give calcium oxide to give calcium trioxocabonate (limestone) to give carbondioxide
Answer:
54 grams of H₂O
Explanation:
4NH₃ + 3O₂ → 2N₂ + 6H₂O
Ratio is 4:6.
Let's convert the mass of ammonia in moles
Mass / Molar mass = Mol
34 g / 17 g/m = 2 moles
If 4 moles of ammonia are needed to produce 6 mol of water
2 mol of NH₃ will produce ( 2 .6 )/4 = 3 moles
Molar mass water = 18 g/m
Mass = mol . molar mass → 3 m . 18 g/m = 54 grams
Answer:
#2.
Explanation:
Look at the charges. Both are positive, therefore both are cations.
