Answer:
the answer for this question is true
Answer:
1. Two to decompose
Explanation:
It's going to be a decomposition so you can eliminate answers 3 and 4. It is a decomposition because it is splitting apart. Then you can figure out that it is going to be two instead of four by balancing the equation
H2O2 → 2H2O + O2
For a reaction to be spontaneous under standard conditions at all temperatures, the signs of ΔH° and ΔS° must be negative and positive, respectively.
<span>Gibbs free energy (G) determines if reaction will proceed
spontaneously, if </span>ΔG is negative, reaction is spontaneous.<span>
ΔG = ΔH - T·ΔS.
ΔG - changes in Gibbs free energy.
ΔH - changes in enthalpy.
ΔS - changes in entropy.
T is temperature in Kelvins.</span>
Answer:
677.39 g/mol
Explanation:
Step 1: Find molar masses of elements
Carbon (C) - 12.01 g/mol
Hydrogen (H) - 1.01 g/mol
Oxygen (O) - 16.00 g/mol
Step 2: Multiply the amount present
12.01 g/mol · 46 = 552.46 g/mol
1.01 g/mol · 92 = 92.92 g/mol
16.00 g/mol · 2 = 32.00 g/mol
Step 3: Add up all the molar masses to find compound molar mass
552.46 g/mol + 92.92 g/mol + 32.00 g/mol = 677.39 g/mol
