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
Spirit designed to explore Planet Mars. It was for NASA's Mars Exploration Rover or MER mission which is an ongoing mission which includes two Mars rovers named Spirit and Opportunity. This is to discover the Martian surface and geology of the Planet Mars.
The theoretical yield of BaCO3 is 5.5
<h3>What is theoretical yield?</h3>
The theoretical yield is the yield calculated from the stoichiometry of the reaction. The equation of the reaction is;
Ba(NO3)2(aq) + Na2CO3 (aq) ------> BaCO3(s) + 2NaNO3(aq)
Number of moles of limiting reactant: 0.4 M × 70/1000 = 0.028 moles
Since the reaction is 1:1,om;y 1 mole of BaCO3 is formed. Hence, mass of BaCO3 = 0.028 moles × 197 g/mol = 5.5g

Hey there :)
The highest solubility of a solute will be when it has the greatest quantity in g when dissolved in 100 g of water. So the solute that is most soluble in water, will have a higher g/100 g water.
1:
a: 0°C - Sucrose will be the solute that is most soluble in water.
b: 80 °C - Also Sucrose will be the most soluble in water.
2:
Yes, as we can see in the graph, sucrose, potassium nitrate, ammonium sulfate and sodium chloride have different solubilities between them and at different temperatures. For example, solubility at 0 °C:
sucrose: 180 g / 100 g of water
potassium nitrate: ~10 g/ 100 g of water
ammonium sulfate: 80 g/100 g water
sodium chloride: 30 g/ 100 g of water
Answer:
The answer is c
