60.7 ml is the volume of a sample of CO2 at STP that has a volume of 75.0mL at 30.0°C and 91kPa.
Explanation:
Data given:
V1 = 75 ml
T1 = 30 Degrees or 273.15 + 30 = 303.15 K
P1 = 91 KPa
V2  =?
P2 = 1 atm or 101.3 KPa
T2 = 273.15 K
At STP the pressure is 1 atm and the temperature is 273.15 K
applying Gas Law:
 =
= 
putting the values in the equation of Gas Law:
V2 = 
V2 = 
V2 = 60.7 ml 
at STP the volume of carbon dioxide gas is 60.7 ml.

'cause alphe-particle which was +ve charge, get repulsion from the atom, so he deducted that.......
        
             
        
        
        
Answer:
It will have 5 valence electrons as its in group 5.
The atom will gain as its closer to the full configuration 8.
The charge will be 3- as it will gain 3 electrons.
 
        
             
        
        
        
it should be B. solution; a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent).
witch basically means it sorts it self out when left a lone, like soap and water when not touched or the oil in the dressings you get at the store. hope this helped :D
