A element mixture (key word: mixture) due to the mixture containing 2 different types of elements it can be said that it’s highly likely that the mixture was not a compound but instead of a mixture due to mixture meaning more than 1 material. Hopes this help!
we are given the reaction Cu + 2AgNO3 ---> Cu(NO3)2 + 2Ag. This means for every mole Cu used, there are 2 moles of Ag produced. In this case, given 31.75 g Cu, converting to moles through molar mass and using stoichiometric ratio and the molar mass of Ag, the mass Ag produced is 107.9 grams.
Answer:
The concentrations are :
The pH of the solution is 3.15.
Explanation:
Initial
c 0 0
Equilibrium
c-x x x
Solving for x:
x = 0.000702 M
Initially
x 0 0
At equilibrium ;
(x - y) y y
Putting value of x = 0.000702 M
Total concentration of

Answer:- D. 1.8 moles of Fe and .
Solution:- The balanced equation is:
let's first figure out the limiting reactant using the given moles and mol ratio:
= 5.4 mol CO
From calculations, 5.4 moles of CO are required to react completely with 1.8 moles of Iron(III)oxide but only 2.7 moles of CO are available. It means CO is limiting reactant.
Products moles depends on limiting reactant. Let's calculate the moles of each reactant formed for given 2.7 moles of CO.
= 1.8 mol Fe
=
So, the correct choice is D. 1.8 moles of Fe and are formed.
80Nm I'm pretty sure this is the answer if I'm wrong I'm sorry but I'm positive it the answer
