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
Cereal is a heterogeneous mixture because it is composed of many different types of ingredients.
Answer:
they are softer as you go deeper
Explanation:
because the core is liquid
Answer:
2.3 M
Explanation:
First we calculate the final volume of the solution:
- Final Volume = 200 mL + 700 mL
With the final volume we can use a <em>dilution factor</em> to c<u>alculate the concentration of the diluted solution</u>:
- Original Concentration * Initial Volume / Final Volume = Final Concentration
- 3 M * 700 mL / 900 mL = 2.3 M
