I believe that the choices for this question are:
C2H4O2, C4H8O4 <span>
CH2O, C6H12O6
C3H6O3, C6H12O6
C2H4O2, C6H12O6 </span>
The answer to this based on the molar masses given is:
C2H4O2, C6H12O6
To prove calculate the molar mass:
C2H4O2 = 2*12 + 4*1 + 2*16 = 60
C6H12O6 = 6*12 + 12*1 + 6*16 = 180
Answer:
98.07848 g mol
Explanation:
Sulfuric acid looks colorless and clear. It is a strong mineral acid.
Answer : The water's temperature change will be, 
Explanation : Given,
Density of water = 0.998 g/mL
Volume of water = 
(conversion used : 1 L = 1000 mL)
Specific heat of water = 
Heat absorbed = 
(conversion used : 1 kJ = 1000 J)
First we have to determine the mass of water.
Now we have to calculate the change in temperature of water.
Formula used :
where,
Q = heat absorbed by water
m = mass of water
= specific heat of water
= change in temperature
Now put all the given value in the above formula, we get:
Therefore, the water's temperature change will be,
The processes that experience energy loss included the following: FREEZING, CONDENSATION AND DEPOSITION.
Energy loss occurs in these processes because the kinetic energy of the particles decreases as a result of the change in state that they undergo. For instance, for the process of freezing, a substance has to change from the liquid state to the solid state. The amount of kinetic energy that is available to the particles of the liquid is more than that of the solid, thus, the particles are losing some kinetic energy.
The processes that experience energy gains are: SUBLIMATION, EVAPORATION AND MELTING. These processes move from a state of lower kinetic energy to that of higher kinetic energy.
