Im sorry I have no clue...
Answer:
false
Explanation:
Only ionic compounds can dissolate in water.
Gas formation, precipitate formation, color change, temperature change, or odor
Answer:
The standard entropy or reaction ΔS° =+324.6J/mol.K
Explanation:
The reaction is
2H2O(l) → 2H2(g) + O2(g)
Standard Molar Entropies of Selected Substances at 298 K are
Substance S∘ (J/mol⋅K)
H2(g) 130.6
O2(g) 205.0
H2O(g) 188.8
H2O(l) 69.9
The standard entropy of reaction will be obtained from standard entropy of formation as given below
ΔH°= 2(130.6)+(205.0)-2(69.9) (Jol/mol.K)
ΔH°=261.2+205.0-139.8
ΔH°=+324.6Jol/mol.K
Answer:
Explanation:
1. Calculate the molar mass of ammonia
1 N = 1 × 14.01 g = 14.01 g
3 H = 3 × 1.008 g = <u> 3.024 </u>
TOTAL = 17.03 g
2. Calculate the mass of hydrogen
So, there are 3.024 g of H in17.03 g of NH₃.
The conversion factor is either
We want to find grams of H, so we choose the one with grams of H on top.
