False because that doesn’t make sense
Hydrogen has only one electron. It has one proton of nucleus and one outter electron.
A. Atoms only. An element cannot be separated into simpler materials
Answer:
See explanation
Explanation:
The reaction equation is;
C3H8 (g) + 5O2(g) -------> 4H2O(g) + 3CO2(g)
From the formula;
Total enthalpy of reactants = (ΔHf of Reactant 1 x Coefficient) + (ΔHf of Reactant 2 x Coefficient)
Total enthalpy of products= (ΔHf of Product 1 x Coefficient) + (ΔHf of Product 2 x Coefficient)
Hence;
Total enthalpy of reactants =[(-103.85 * 1) + (0 * 5)] = -103.85 + 0 = -103.85 KJ/mol
Total enthalpy of products= [(-393.51 * 4) +(-241.82 * 3)] = (-1574.04) + (-483.64) = -2057.68 KJ/mol
Answer:
Explanation:
Hello there!
In this case, given the by-mass percent of ethanol:
It is possible to compute the density by using its molar mass to find the grams in one liter of solution:
However, by taking the g/mL we obtain:
Which is the density of the solution.
Best regards!
