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.
Answer:
The answer to your question is P2 = 170.9 torr
Explanation:
Data
Volume 1 = 12.1 l Volume 2 = 21.1 l
Temperature 1 = 241 °K Temperature 2 = 298°K
Pressure 1 = 546 torr Pressure 2 = ?
Process
To solve this problem use the combined gas law.
P1V1/T1 = P2V2/T2
-Solve for P2
P2 = T1V1T2 / T1V2
-Substitution
P2 = (241 x 12.1 x 298) / (241 x 21.1)
-Simplification
P2 = 868997.8 / 5085.1
-Result
P2 = 170.9 torr
Answer:
An atom is the smallest particle of an element that can take part in a chemical reaction while a molecule is a group of chemically combined atoms.
Explanation:
Explanation:
where,
R = Gas constant =
T = temperature =
= equilibrium constant at 600°C = 0.900
Putting values in above equation, we get:
The ΔG° of the reaction at 764.85 J/mol is 764.85 J/mol.
Equilibrium constant at 600°C =
Equilibrium constant at 1000°C =
The ΔH° of the reaction at 600 C is -18,969.30 J/mol.
ΔG° = ΔH° - TΔS°
764.85 J/mol = -18,969.30 J/mol - 873.15 K × ΔS°
ΔS° = -22.60 J/K mol
The ΔS° of the reaction at 600 C is -22.60 J/K mol.
Partial pressure of carbon dioxide =
Partial pressure of carbon monoxide =
Where mole fraction of carbon dioxide and carbon monoxide gas.
The expression of is given by:
Mole fraction of carbon dioxide at 600°C is 0.474.
Answer:
<h3>The answer is 8.2 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 62.4 g
volume = 7.6 cm³
We have
We have the final answer as
<h3>8.2 g/cm³</h3>
