HCl and NaOH react based on the following equation:
HCl + NaOH ..............> NaCl + H2O
This reaction is known as a double replacement reaction. In this types of reactions, the electrolyte (and the solvent) is water and the driving force is mainly the formation of a non-electrolyte produce.
Based on this, the driving force in the above neutralization reaction is the formation if the non-electrolyte salt (NaCl)
C. Hydropower would need dams to be built, and this will prevent fishes from going upstream.
Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
Now, as the stoichiometrical factors are in terms of mole but no information about neither the temperature nor the pressure is given, by means of the Avogadro's law, one could perform the stoichiometric calculations with the given volume as both the pressure and temperature remain the same, that is:
Such 1:1 volume relationship equals the 1:1 molar relationship given in the chemical reaction in terms of their stoichiometric coefficients, therefore, the yielded volume of carbon dioxide is also 9.23m³
Best regards.
The periodic table was arranged by Mendeleev in the increasing order of atomic numbers. The arrangement sees to it that the elements belonging to the same column has similar properties and the rows are arranged in increasing number of valence electrons. The answer here is true.
Answer:
C
Explanation:
Well, we can see from the equation that hydrogen gas and ethane are in a 2:1 ratio based on their mole coefficients.
You need 2 mol H2 to make 1 mol C2H6. So that means you need 2*13.78 mol H2 to make 13.78 mol C2H6!
2*13.78 = 27.56 mol
C is correct.
