The chemical reaction would be:
C3H8 + 5O2 = 3CO2 + 4H2O
For this case, we assume that gas is ideal thus in every 1 mol the volume would be 22.41 L. We calculate as follows:
28.7 L C3H8 ( 1 mol / 22.41 L ) ( 4 mol H2O / 1 mol C3H8 ) ( 18.02 g / mol ) = 92.31 g H2O produced
Hope this answers the question.
        
             
        
        
        
HNO3+KOH = H2O+KNO3 . When nitric acid react with pottasuim hydroxide, the reaction will produce water (H20) and pottasuim trioxonitrate
        
                    
             
        
        
        
Answer:
Explanation:
In order to convert 6.7 hectometers to meters using dimensional analysis, you must use the ratio of hectometers to meters.
There are 100 meters in one hectometer, then you start setting the equality: 100 m = 1 hm. 
Dividing both sides by 1 hm you get the fraction form of the ratio, with meters (m) in the numerator and hectometers (hm) in the denominator. 
               
Since hm is in the numerator, when you multiply 6.7 hm by the unit ratio the hm will be canceled and the result will have only m:
             
 
        
             
        
        
        
Answer:
The amount is 
Explanation:
From the question we are told that 
      The  distance traveled per day is  
     The  cost of one liter is  
      The car's  gas mileage is  
Generally the amount of distance covered in one week is evaluated as 
       
        
The  amount of gas used in one week by the car is mathematically represented as  
        
=>    
=>      
converting to liters 
           
Thus the amount spent on gas in one week is  
           
=>      
=>      
  
 
        
             
        
        
        
Once molecules are close enough to touch, intermolecular forces become replusive in order to prevent the molecules from overlapping.
