Answer:
7.28 × 10³ K
Explanation:
Let's consider the following reaction.
N₂(g) + O₂(g) → 2 NO(g)
The reaction is spontaneous when the standard Gibbs free energy (ΔG°) is negative. ΔG° is related to the standard enthalpy of the reaction (ΔH°) and the standard entropy of the reaction (ΔS°) through the following expression.
ΔG° = ΔH° - T . ΔS°
If ΔG° < 0,
ΔH° - T . ΔS° < 0
ΔH° < T . ΔS°
T > ΔH°/ΔS° = (180.5 × 10³ J/mol)/(24.8 J/mol.K) = 7.28 × 10³ K
The reaction is spontaneous above 7.28 × 10³ K.
Answer:
Dispersion forces- Xe, CH4
Dipole-dipole forces-CHCl3
Hydrogen Bonding-HBr, NH3, CH3COOH
Explanation:
Gases and nonpolar molecules posses only dispersion forces. Polar covalent compounds posses dipole- dipole forces. When hydrogen is bonded to a highly electronegative atom, hydrogen bonding results. These account for the arrangement of answers above.
Answer:
c
Explanation:
we cannot say that either will die out, because we dont know the conditions. but we know that both sides out the mountian arent exactly the same, so we know they will evolve to adapt and grow with what they have
Answer is: carbon dioxide and water <span>are released during cellular respiration.
</span>Chemical reaction of cellular respiration:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O.
There are 18 oxygen atoms (six in glucose and twelve in six molecules of oxygen) in left side of chemical reaction and also 18 oxygen atoms (twelve in six molecules of carbon dioxide and six in six molecules of water) at the right.
Answer:
AAU UCG
Explanation:
<em>According to the base-pairing rule, the purine bases always pair with the pyrimidine bases. More specifically, Adenine always pairs with Thymine/Uracil while Guanine always pairs with Cytosine.</em>
T - A
T - A
A - U
A - U
G - C
C - G
Hence, the transcription of the sequence TTA AGC will produce AAU UCG.
