Answer:
a) 1.8 kJ
Explanation:
ΔG=-RtLnK
Just input the data into the equation to gives us the result, in Joules.
ΔG=-8.314*(25+273.15)*ln(0.48)
ΔG=1819,37 J
But there is only 2 significant figures, so we express it as or 1.8 kJ
Answer:
91.33 L
Explanation:
For an ideal gas, the product between the gas pressure and the gas volume is proportional to the absolute temperature of the gas. Mathematically:
where:
p is the pressure of the gas
V is the volume of the gas
T is the absolute temperature of the gas
For a transformation of the gas, we can write:
For the sample of krypton in this problem, we have:
(initial pressure)
(initial volume)
(initial temperature)
(final pressure, at stp)
(temperature at stp)
Therefore, the volume at stp is:
5. Ionic
6.Ionic
7. Both
8. Covalent

Answer:
The answer to your question is Mg loses its valence electrons and acquire a positive charge (Mg⁺²).
Explanation:
Valence electrons are important for an element to attach to another one, metals lose these electrons while nonmetals gain electrons to complete the octet rule.
Magnesium is a metal that loses these electrons so when it becomes an ion Magnesium will have a positive charge Mg⁺².
