The molar mass of water is the molecular weight in grams per 1 mole.
18gH2O/1mole
100g × 1mole/18g = 50/9 moles = 5.67 moles H2O
Answer:
BaSO₄
Explanation:
Let's assume we have 100 g of the compound. If that's the case we would have:
Now we <u>convert the masses of each element into moles</u>, using their <em>respective molar masses</em>:
- 58.8 g Ba ÷ 137.327 g/mol = 0.428 mol Ba
- 13.74 g S ÷ 32 g/mol = 0.429 mol S
- 27.43 g O ÷ 16 g/mol = 1.71 mol O
We <u>divide those moles by the lowest number among them</u>:
We can express those results as Ba₁S₁O₄, meaning the empirical formula is thus BaSO₄.
Answer:
Blue or green
Explanation:
A chemical called anthocyanin is in red cabbage juice, which changes color depending on the pH of its environment. Dishwasher soap is usually alkaline, making the juice turn a blue-green color.
Answer:
2NH3+3/2O2=N2+3H2O
Explanation:
balance both sides to have equal elements. LHS:N RHS:N2
H3 H2
O2 O
