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.

Unknown element x is a metal that ionically bonds to sulfur.is the formula, x3s feasible? why or why not?a)it is feasible. the t

nasty-shy [4]

The correct answer is:
d) No, it is not feasible. three metallic ions cannot provide the exact number of electrons that one sulfur needs for the ionic bond.
Because Sulfur is divalent so it need to gain 2 electrons from metal so if we have 3 metals they can't provide only two electrons only.
