Explanation:
The given data is as follows.
    = 98.70 kPa = 98700 Pa,
 = 98.70 kPa = 98700 Pa,   
       T =  = (30 + 273) K = 303 K
 = (30 + 273) K = 303 K 
       height (h) = 30 mm = 0.03 m (as 1 m = 100 mm)
Density = 13.534 g/mL = 
                 = 13534 
The relation between pressure and atmospheric pressure is as follows.
              P = 
Putting the given values into the above formula as follows.
             P = 
                = 
                = 102683.05 Pa 
                = 102.68 kPa
thus, we can conclude that the pressure of the given methane gas is 102.68 kPa.
 
        
             
        
        
        
<span>Pentane has a boiling point of 36.1 C, while isopentane boils at 27.7C. Neopentane has the lowest boiling point at 9.5 C. Therefore from highest to lowest boiling points, it is pentane, isopentane, and neopentane.</span>
        
             
        
        
        
They all don’t, they also can have positive charges like LiOH (Lithium Hydroxide)
        
             
        
        
        
Answer:
Basicity is measured on a scale called the pH scale. On this scale, a pH value of 7 is neutral, and a pH value of more than 7 to 14 shows increasing basicity.
pH value of 7 is weak base and value of 14 means strong base.
