Answer: The pressure in the can is 4.0 atm
Explanation:
According to ideal gas equation:
 
P = pressure of gas = ?
V = Volume of gas = 0.410 L
n = number of moles =  
R = gas constant = 
T =temperature = 
 
 
Thus the pressure in the can is 4.0 atm
 
        
             
        
        
        
The answer is (3) a homogeneous mixture. The difference between homogeneous and heterogeneous mixture is the degree of the mixture being mixed. Due to the completely dissolved and the dissolving ability of KCl, we can get the answer,
        
             
        
        
        
Answer:
Electronegativity varies in a predictable way across the periodic table. Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.Explanation:
