Answer:
So ²³⁵UF₆ effuses 1.0043 times faster than ²³⁸UF₆
Explanation:
The rate of effusion of two gases A and B can be expressed by <em>Graham's law</em>:
Where M is the molar mass, and in this case A is ²³⁵UF₆ while B is ²³⁸UF₆.
So now we <u>calculate the molar mass of each mass</u>:
²³⁵UF₆ ⇒235 + 6*19 = 349 g/mol
²³⁸UF₆ ⇒238 + 6*19 = 352 g/mol
Putting the data in Graham's law:
= 1.0043
So ²³⁵UF₆ effuses 1.0043 times faster than ²³⁸UF₆.
The number of sandwiches that can made with 6 pieces of bread and 4 slices of cheese is 3 sandwiches.
<h3>What are limiting reactants?</h3>
Limiting reactants are those reactants which determine the amount of product that can be formed since they get used up in a reaction.
In the making of sandwiches from bread and cheese, the limiting reactant is the material that is used up.
The formula for making a sandwich is given below;
2 pieces of bread + 1 slice of cheese = 1 sandwich
6 pieces of bread can make 3 sandwiches
4 slices of cheese can make 4 sandwiches
Thus, bread is the limiting reactant.
Therefore, the number of sandwiches that can made with 6 pieces of bread and 4 slices of cheese is 3 sandwiches.

See explanation
Explanation:
The cold drink chiller is a cold substance which is inserted into a bottle of drink which contains warm liquid particles at a particular temperature.
Once the drink chiller is inserted, the liquid molecules around the drink chiller become cooler, denser and sink away from the drink chiller. Other warmer, less dense molecules of the liquid drink now replaces them around the drink chiller.
A convection current is thus set up for as long as the drink chiller is working.
