Explanation:
to calculate theoratical yield...first we must calculate how much Sucrose moles we have..in order to to do so...we must calculate molar mass of sucrose.
molar mass of sucrose is 342.3 g/mol.
now we can calculate how many sucrose moles we have by dividing the mass with molar mass of sucrose
735g/(342.3g/mol)=2.147mol
theoratically...according to stoichiometry..every 1 mole of sucrose yields 4 moles of ethanol...so...
2.147mole yield 2.147*4mol=8.588mol
now we must calculate weight of that much ethanol..molar mass of ethanol is 46.07 g/mol...
so we can multiple moles by molar mass to obtain the weight 8.588mol*46.07g/mol=395.649g
but we only obtained 310.5g...so percentage we have is
78.47%
if there is trouble with molar mases I used....use what you calculated...
If my explanation is good enough...please mark it as brainliest.thanks
Answer:
Boyle's Law
Explanation:
This is a simple Boyle's law at work in this scenario.
Boyle's law is one of the gas law and it states that "The volume of a fixed mass of gas varies inversely as the pressure changes if temperature is constant".
This law was proposed by Robert Boyle.
- In a sealed syringe, the volume of gas begins to decrease as the plunger is pressed.
- Conversely, it becomes harder to press due to increasing pressure in the tube.
- The pressure pushes back the more it is applied.
- We can see that the higher pressure applied, the lower the volume of the gas.
This is clear cut practical of the Boyle's law.
Answer:
liquid
Explanation:
it means it changes the form to a different way than the first one
The average speed of the horse for the entire motion is 66.67 m/s.
The given parameters;
- <em>distance traveled by the horse, d = 1 km = 1,000 m</em>
- <em>time of motion of the horse, t = 15 s</em>
The average speed of the horse is calculated by dividing the total distance traveled by the horse by the time of motion.
The average speed of the horse is calculated as follows;
Thus, the average speed of the horse for the entire motion is 66.67 m/s.
