2 answers:

8 0

If the number of electrons is not given, your answer would be +3.

Explanation: Protons have positive charge, electrons have negative charge, and neutrons have no charge. Therefore, having three protons and 3 neutrons would give you a net +3 charge.

Hope this helps!

If I have 6 moles of a gas at a pressure of 3.4 atm and a volume of 10 liters, what

ch4aika [34]

Answer:

The temperature is 69.05 K.

Explanation:

We have,

Number of moles are 6

Pressure is 3.4 atm and a volume of 10 liters.

It is required to find the temperature. It can be calculated using gas law equation. It says that,

$PV=nRT$

P is pressure

V is volume

n is number of moles

R is gas constant, $R=0.082057\ L-atm/mol-K$

T is temperature

Plugging all the values we get :

$T=\dfrac{PV}{nR}\\\\T=\dfrac{3.4\times 10}{6\times 0.082057}\\\\T=69.05\ K$

So, the temperature is 69.05 K.
