The brightness is often known as the star's apparent magnitude when they do a basic observation of how bright the star appears.

Answer is: B. apparent magnitude.

The magnitude of star is a measure of its brightness. The lower the magnitude number, the brighter the star.

Apparent magnitude is the brightness of a star as seen from Earth.

Absolute magnitude is the apparent magnitude of a star (or some other astronomical object) if it were 32.6 light years away from Earth and in the absence of any sources (dust, gases) that could interfere with its brightness.

Luminosity is the total amount of energy emitted per unit of time by a star.

I<br> Solid iron(III) oxide is produced when hot iron filings are exposed to pure<br> oxygen gas.
Sergeu [11.5K]
The unbalanced equation is:
Fe(s) + O2(g) —> Fe2O3(s)

To balance oxygens, multiply O2 by 3 and Fe2O3 by 2.

Fe(s) + 3O2(g) —> 2Fe2O3(s)

Balance your iron by multiplying Fe by 4, since you have 4 Fe in the products now.

4Fe(s) + 3O2(g) —> 2Fe2O3(s)

A gas has a volume of 450. mL at 55.0 °C. If the volume changes to 502 ml, what is the new temperature?
salantis [7]

Answer:

92.9 °C

Explanation:

Step 1: Given data

  • Initial volume (V₁): 450. mL
  • Initial temperature (T₁): 55.0 °C
  • Final volume (V₂): 502 mL

Step 2: Convert 55.0 °C to Kelvin

We will use the following expression.

K = °C + 273.15 = 55.0 + 273.15 = 328.2 K

Step 3: Calculate the final temperature of the gas

If we assume constant pressure and ideal behavior, we can calculate the final temperature of the gas using Charles' law.

T₁/V₁ = T₂/V₂

T₂ = T₁ × V₂/V₁

T₂ = 328.2 K × 502 mL/450. mL = 366 K = 92.9 °C
