Answer: 61 grams
Explanation:
To calculate the number of moles, we use the equation:
The chemical equation for the combustion of octane in oxygen follows the equation:
By stoichiometry of the reaction;
25 moles of oxygen react with 2 moles of octane
4.69 moles of oxygen react with=
moles of octane
Thus, oxygen is the limiting reagent as it limits the formation of product and octane is the excess reagent.
25 moles of oxygen produce 18 moles of water
4.69 moles of oxygen produce=
moles of water.
Mass of water produced=
The maximum mass of water that could be produced by the chemical reaction is 61 grams.
Answer:
A. Up
B. Out
C. Out
D. To equilibrum
Explanation:
a. The reaction in an exothermic reaction so this means heat is given off. If the cylinder is thin enough heat will transfer to the water bath
b. Since the products will create heat which will increase pressure, the piston in an attempt to maintaining a constant pressure will move up to accommodate building pressure.
c. Heat will flow out of the gaseous mixture as this reaction creates heat as a product as well
d. Heat will flow out in the capacity to create an equilibrium with the water bath that it is in.
Answer:
2NaHCO3 + H2SO4 -----> Na2SO4 + 2H2O + 2CO2.
Explanation:
Answer:
a chemical reaction
Explanation:
The fact that you are combining two different elements together makes this a chemical reaction. (hope that helps)
Gaining electrons would mean that it is near the stable octet, so it needs more.
Right side would be the answer
