Answer:
Sure let me take a look at it
Explanation:
Answer:
limiting reagent is given by
- calculated or given no. of moles
- divided by
- stocheomatric or no. of moles from equation.
Avagadros number states that 1 mol of any substance is made of 6.022 x 10²³ units.
1 mol of Cu is made of 6.022 x 10²³ atoms of Cu.
the molar mass of Cu is - 63.5 g/mol
63.5 g of Cu is made of 6.022 x 10²³ atoms of Cu
therefore 127.08 g of Cu contains - 6.022 x 10²³ atoms / 63.5 x 127.08
number of Cu atoms - 1.20 x 10²⁴ atoms of Cu
answer is 1) 1.20 x 10²⁴ atoms
Answer:
it has to do with shearing at transform boundaries and strike-slip faults where tectonic plates slide past eachother in opposite directions where crust isn't created or destroyed
