Answer:

oatmeal with raisins is a heterogeneous mixture. The raisins may be solid, but turn the bowl over and you will see the mixture as a whole most definitely acts like a liquid. Mud puddles are a heterogeneous mixture.

Given the following reaction:
Semenov [28]

Answer:

The answer to your question is 0.35 moles of ZnCl₂

Explanation:

Data

moles of ZnCl₂ = ?

mass of Zn = 23 g

mass of CuCl₂ = excess

Balanced chemical reaction

             Zn + CuCl₂   ⇒   ZnCl₂  +  Cu

Process

1.- Convert the mass of Zn to moles

-Look for the atomic mass of Zn

Atomic mass = 65.4 g

-Convert the grams to moles

            65.4 g -------------- 1 mol

             23 g  ----------------  x

               x = (23 x 1)/65.4

               x = 23 / 65.4

               x = 0.35 moles of Zn

2.- Calculate the moles of ZnCl₂ using proportions and cross multiplication, and the coefficients of the balanced chemical reaction.

              1 mol of Zn ---------------- 1 mol of ZnCl₂

             0.35 moles of Zn --------  x

              x = (0.35 x 1) / 1

              x = 0.35 moles of ZnCl₂

What is true about two neutral atoms of the element gold
choli [55]
I'm pretty sure it's they have the same properties, because they don't have different masses, they don't both have missing nuclei, and they don't hav a different # of protons. Can't recall much else about the two, but I distinctly remember that

  VIII                                 0                                                          8

For elements in group IV and above, their ionic charge is (8-number of their valence electrons.)
