Answer:
moles of Threobromine are present in chocolate bar
Explanation:
Molar mass of Theobromine = (molar mass of C)+(
molar mass of H)+(
molar mass of N)+(
molar mass of O) = (
12g/mol)+(
1g/mol)+(
14g/mol)+(
16g/mol) = 180 g/mol
We know that, number of moles of a compound is the ratio of mass to molar mass of the compound.
So, 0.064 g of Threobromine = moles of Threobromine =
moles of Threobromine
Answer: single replacement reaction,
Explanation:
A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.
A general single displacement reaction can be represented as :
As strontium metal is added to aluminum chlorate , strontium being more reactive than aluminium, displaces aluminium atom its salt solution and lead to formation of strontium chlorate and aluminum metal.
