A gas occupies 547 L at 331K. Find its volume at 376K. You must show all of your work to receive credit. Also, name the gas law
zysi [14]

621.4L

Explanation:

Given parameters:

Initial volume = 547L

Initial temperature = 331K

Final temperature = 376K

Unknown:

Final volume = ?

Solution:

The appropriate gas law to use is the Charles's law.

The Charles's law shows the relationship between the volume and temperature of a gas under constant pressure.

The law states that "The volume of a fixed of a gas varies directly as its absolute temperature if the pressure is constant".

Mathematically;

    \frac{V_{1} }{T_{1} }  = \frac{V_{2} }{T_{2} }

 V₁ is the initial volume

 T₁ is the initial temperature

 V₂ is the final volume

 T₂ is the final temperature

Since the unknown is the final volume, we make it the subject of the expression;

   V₂ = \frac{V_{1} }{T_{1} }  x T_{2}  = \frac{547}{331 }  x 376

 V₂ =  621.4L

What is the mass number of an atom containing 35 protons and 45 neutrons?
vodka [1.7K]

Answer:

Explanation:

1. Weight = 35 P and 45 N = 80

2. Atom:  35P = 35 electrons

3. Bromine

4. It's a non metal. It's in column 17. It will gain 1 electron (normally).

5. Ion: 35 protons, 36 electrons

6. Charge: - 1 usually, but there are exceptions

7. Anions go to the Anode. The anode attracts minus charged elements.

8. In an uncharged state, element 36 would be next. That would be  Krypton which is always uncharged. It is a noble gas.
