Answer:
The mass ratio of oxygen rounded to the nearest whole no. 3 : 2
Explanation:
According to Law of Multiple proportion when two elements combine to make two or more different compounds, the mass ratio of the two element in the first compound, when divided by the mass ratio of the second compound , form a simple whole number ratio.
 Compound A contains 1.34 g of sulfur for every 0.86 g of oxygen
         
Compound B contains 11.63 g of sulfur for every 10.49 g of oxygen
       
Ratio of oxygen in each compound 
    always put the larger number over the smaller number.

 
        
             
        
        
        
There are three different forms of potential energy. The rock hanging above the ground has a form of stored energy called gravitational potential energy. This form of energy is due to the downward pull of Earth's gravity. ... When you stretch a rubber band, the elastic potential energy of the rubber band increases.
 
        
             
        
        
        
Answer:
The value of  the heat capacity of the Calorimeter   = 54.4
 = 54.4 
Explanation:
Given data 
Heat added Q = 4.168 KJ = 4168 J
Mass of water  = 75.40 gm
 = 75.40 gm
Temperature change = ΔT = 35.82 - 24.58 = 11.24 ° c
From the given condition 
Q =  ΔT +
 ΔT +  ΔT
 ΔT
Put all the values in above equation we get
4168 = 75.70 × 4.18 × 11.24 +   × 11.24
 × 11.24
611.37 =   × 11.24
 × 11.24
  = 54.4
 = 54.4 
This is the value of  the heat capacity of the Calorimeter.
