Answer:
She turned back at the point at which she forgot she left her briefcase. If this isn't the correct answer, please be more specific in the question.
Explanation:
Neutron star: a newly formed neutron star can have a temperature of about 10^11 Kelvin to 10^12 Kelvin, but it can drop to 10^6 Kelvin. Its brightness is a million times fainter than the sun's brightness because of its size and distance from a point of view.
Dwarf star: Yellow dwarfs are small, main sequence star. <span>Red dwarfs are the most common type of star, </span>it's a small, cool, very faint, main sequence star whose surface temperature is under about 4,000 K.
Main sequence: has a temperature of about 10 million K. Its luminosity depends on the size and the mass of the star.
Red Giant: not normally as bright as the main sequence but it can create 1,000 to 10,000 times the luminosity that the sun gives off. The outer atmosphere is inflated, making the surface temperature to be as low as 5,000 K.
Supergiant: These stars have very "cool" surface temperatures that can range between 3500 and 4500 K (more or less). Depending on proximity, size, and mass, their luminosity can be either very high or very dim... though, they are normally very large stars.

The balanced equation :
<em>2Al₂O₃⇒ 4Al+3O₂</em>
<h3>Further explanation</h3>
Given
Reaction
Al₂O₃⇒ Al+O₂
Required
Balanced equation
Solution
A chemical reaction is said to be balanced if the number of elements involved in the reaction is the same (either the reactants or the products)
The reaction above is said to be unbalanced because the number of elements Al and O in the reactants and products is not the same.
The balancing step
1. Give a coefficient
Al₂O₃⇒ aAl+bO₂
2. Make an equation
Al, left = 2, right = a⇒a=2
O, left = 3, right = 2b⇒2b=3⇒b=3/2
The equation becomes :
Al₂O₃⇒ 2Al+3/2O₂ x2
<em>2Al₂O₃⇒ 4Al+3O₂</em>
As per Ideal gas equation, molar mass of the gas is 5.032 g/mo
We’ll begin by calculating the number of mole of the gas. This can be obtained as follow:
Volume (V) = 1.6 L
Temperature (T) = 287 K
Pressure (P) = 0.92 atm
Gas constant (R) = 0.0821 atm.L/Kmol
Number of mole (n) =?
According to Ideal gas equation , PV = nRT
0.92 × 1.6 = n × 0.0821 × 287
1.472 = n × 23.5627
Divide by 23.5627
n = 1.176 / 23.5627
n = 0.0624 mole
Finally, we shall determine the molar mass of the gas. This can be obtained as follow:
Mass of gas = 0.314 g
Number of mole = 0.0624 mole
Mole = 
0.0624 = 
Cross multiply
0.0624 × molar mass of gas = 0.314
Divide by 0.0624
Molar mass of gas = 
Molar mass of gas = 5.032 g/mo
Therefore the Molar mass of gas is 5.032 g/mo
