Answer: 6.2 moles
Explanation:
C3H8(g) + 5O2(g) ---> 3CO2(g) + 4H2O(g)
The balanced equation above shows the combustion of propane, C3H8 in oxygen, O2 to yield carbon dioxide, CO2 and water, H2O
The mole ratio of combustion are as follows:
1 mole of C3H8 react to produce 4 moles of H2O
1.55 mole of C3H8 will react to produce Z moles of H2O
To get the value of Z, cross multiply
Z x 1 mole = 1.55 mole x 4 mole
Z = 6.2 moles
Thus, 6.2 moles of water will be produced from 1.55 moles of propane
Answer: 2. Density
3. Physical Property
4. Chemical Change
5. states of matter
Explanation: Density is referred as mass per unit volume. Physical properties are observable characteristics of an object. An new formation of a substance in a chemical reaction is a chemical change. And solids, liquids, and gases are states of matter.
Answer:
6.67 moles of NH₃
Explanation:
From the equation of reaction,
4NH₃(g) + 7O₂(g) → 4NO₂(g) + 6H₂O(g),
4 moles of NH₃ will produce 6 moles of 6H₂O,
X moles of NH₃ will produce 10 moles of H₂O
X = (10 * 4) / 6
X = 6.67 moles of NH₃
6.67 moles of NH₃ will produce 10 moles of H₂O
it is a postive ionnnnnnnnnnnnnnnnnnnnn
