How many moles of zinc are needed to react with 45.60 moles of nitric acid?

Chemistry

uranmaximum [27]3 years ago
3 0

Answer:

11.4 moles

Explanation:

Your chemical equation for the reaction of zinc and nitric acid will be

Zn  +  4 HNO₃  -->  Zn(NO₃)₂  +  2 NO₂  +  2 H₂O

To solve the problem, you need to use stoichiometry.  For every 1 mole of zinc, you will need 4 moles of nitric acid.  Divide 45.60 by 4.  Your answer should be 11.4 moles.

What is the limiting reactant if 0.5 g Al is reacted with 3.5 g CuCl2?
DIA [1.3K]
The balanced equation for the above reaction is 
2Al + 3CuCl₂ --> 2AlCl₃ + 3Cu
stoichiometry of Al to CuCl₂ is 2:3
limiting reactant is when the reactant is fully consumed in the reaction therefore amount of product formed depends on amount of limiting reactant present. 
number of Al moles  - 0.5 g  / 27 g/mol = 0.019 mol
number of CuCl₂ moles - 3.5 g / 134.5 g/mol = 0.026 mol
if Al is the limiting reactant 
if 2 mol of Al reacts with 3 mol of CuCl₂
then 0.019 mol of Al reacts with - 3/2 x 0.019 = 0.029 mol of CuCl₂
but only 0.026 mol of CuCl₂ is present 
therefore CuCl₂ is the limiting reactant 
and 0.026 mol of CuCl₂ reacts with - 0.026/3 x 2 = 0.017 mol of Al is required
but 0.019 mol of Al is present 
therefore CuCl₂ is the limiting reactant and Al is in excess

Predict the number of peaks that you would expect in the proton-decoupled 13C spectrum of each comound.
dangina [55]

Answer:

To interpret a 13C-NMR spectrum we will use some standards very simple. A  13C-NMR spectrum gives us the following information:

1. Indicates the number of non-equivalent carbons in the molecule.

2. Measuring the chemical shift we can intuit the environment

electronic and determine the next functional groups.

3. In this case we cannot count on integration since the different

carbons have different relaxation times.

The number of peaks in the spectrum indicates the number of types of carbon present in the analyzed substance.

The factors that influence the chemical shift of the signals in the 13C NMR are:

  • electronegativity of carbon bound groups
  • carbon hybridization

Explanation:

The nuclear magnetic resonance of C13 is complementary to that of H1. This technique is used to determine the magnetic environment of carbon atoms.
