Answer: d=m/v
Explanation: The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
For question 1:
<span>25°C = 298 K
</span><span>ΔG = ΔH - T ΔS
</span>ΔH= ΔG + TΔS = −91368 + (298)(−284)=−91368-84632=-175730
<span>Therefore ΔH is approx - 176,000 J
</span>
For question 2:
The statement "A negative change in free energy, or −ΔG, represents a spontaneous reaction." is false
Answer:
The fact that the green ink separated from the rubbing alcohol proves that it is indeed a mixture.
