You have a mixture of sucrose (C12H22O11) and sand (SiO2) in a beaker. What type of mixture is this? Explain how you know. What process(es) would be best to separate this mixture? Describe the process.
A mixture of sucrose and sand is a heterogeneous mixture. We say that because both the components are not of same composition throughout and in mixture they look non uniform.
We can separate sand and sucrose by simply adding water in the mixture. As we all know, sugar will get dissolve in water and sand will settle down(as it has more density than water).
Then filter the mixture and evaporate the water. We will get sugar and sand separately.

You take 20.0g of a sucrose (C12H22O11) and NaCl mixture and dissolve it in 1.0L of water. The freezing point of this solution is found to be -0.426 degress celsius. Assuming ideal behavior, calculate the mass percent composition of the original mixture, and the mole fraction of sucrose in the original mixture
You have a sample that contains sucrose, sand and copper sulfate. Would you be able to separate these three components from each other, if so how?
1.describe how you would separate a mixture of acetanilide and sand 2.water is a convenient solvent for recrsytallizing what type of compound. 3. why is fluted filter paper usually used when doing the hot filtration during a recrystallization. 4.describe how seed crystal are used in recrystallization. 5.explain the adage " like dissolve lik
2) How many grams of sucrose (C12H22O11) would you need to make 650 mL of a 4.5 mM aqueous solution?
1) How would you separate NaCl and SiO2? 2) Why it is necessary to heat a mixture to start a chemical reaction?
A sugar crystal contains approximately 1.0×10^17 sucrose (C12H22O11) molecules. What is its mass in milligrams? Thank you :) Step by step would be helpful, having trouble getting the right answer:/
Question 2,3,4 please.
ESTIONS: 1. Many students do not recover 100% of the original mixture. Describe at least two possible problems that could cause less than 100% recovery of the mixture. 2. A student received a mixture that actually contained 50.0% salt and 50.0% sand. At the end of the experiment, this student calculated that his sample was composed of 45.2% salt and 54.8% sand. What might he have done (or not done correctly) during the experiment to cause this...
explain the steps of a procedure you would use to separate and recover a) mixture of sodium chloride and sodium iodide b) mixture of sand and sodium chloride
which type of soil would you expect to have the most available water? Sand Silty clay Loam Clay If the temperature of a plant is 18C and the ambient temperature is 14C, which process will result in a net input of heat from the air to the plant ? Conduction Convection Evaporation None of the above
A beaker containing HCl solution is neutralized with 0.7M KOH solution. What do you know about the ratio [H3O]+/[OH]-in the reaction mixture at the end point?<1>1 1The same HCl solution can also be neutralized with 0.7M Ca(OH)2 solution. What would be the ratio [H3O]+/[OH]- in the reaction mixture at the end point in this case?1<1 >1
