Answer: = 0.01
Explanation:1 centiliters = 0.01 liters using the online calculator for metric conversions.
The answer is metal. Metals are always named first in ionic compounds, like KNO3 for example. I hope this helps!
Density=mass/volume
0.7198=m/11.84
mass=0.06g
∆H ° rxn =-2855.56 kJ
<h3>Further explanation</h3>
Given
ΔHf CO₂ = -393.5 kJ/mol
ΔHf H₂O = -241.82 kJ/mol
ΔHf C₂H₆ = - 84.68 kJ/mol
Reaction
2C2H6(g) + 7O2(g) -> 4CO2(g) + 6H2O(g)
Required
ΔHrxn=
Solution
<em>∆H ° rxn = ∑n ∆Hf ° (product) - ∑n ∆Hf ° (reactants) </em>
∆H ° rxn = (4.-393.5+6.-241.82)-(2.-84.68)
∆H ° rxn = (-1574-1450.92)-(-169.36)
∆H ° rxn =-3024.92+169.36
∆H ° rxn =-2855.56 kJ
a. The balanced chemical equation is: Zn+2HCl→ZnCl2+H2.
b. The overall reaction is: Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
c. The spectator ion is: zinc
d. The net ionic equation is: Zn ₅ + 2H⁺ (aq) → Zn ²⁺ (aq) + H₂ (g)
<h3>What are Spectator ions?</h3>
Spectator ions are ions that are present in chemical processes but do not take part in them and are the same on both sides of the reactions. The spectator ions are cancelled from both sides of the equation in the net chemical reaction.
<h3>What is the definition of ionic reactions?</h3>
In general, ionic reaction occurs when anions and cations combine to generate a compound in a liquid or solid media. Water-insoluble salts are created when the ions of salts that are soluble in water interact with one another.
