Answer:

m_{Cr_2O_3}^{actual}=62.4gCr_2O_3

Explanation:

Hello!

In this case, according to the reaction:

4Cr+3O_2\rightarrow 2Cr_2O_3

We can see there is a 4:2 mole ratio between chromium and chromium (III) oxide, this, for the given 56.2 g of chromium, the theoretical yield of the oxide product is computed down below:

m_{Cr_2O_3}^{theoretical}=56.2gCr*\frac{1molCr}{52.0gCr}*\frac{2molCr_2O_3}{4molCr} *\frac{151.99gCr_2O_3}{1molCr_2O_3}  =82.13gCr_2O_3

Now, considering the 76.0-% yield for this reaction, the actual yield turns out:

m_{Cr_2O_3}^{actual}=82.13gCr_2O_3*\frac{76.0gCr_2O_3}{100gCr_2O_3} \\\\m_{Cr_2O_3}^{actual}=62.4gCr_2O_3

Best regards!

List the type of reaction. Predict the outcome and balance.
Yuliya22 [10]

Answer:

Single Displacement Reaction: a reaction in which an element is swapped for another in a molecule

A + BC ---> AC + B

Double Displacement Reaction: a reaction in which the cation of one molecule is swapped with a cation of another molecule

AB + CD ---> AD + CB

a) Single Displacement Reaction

3 Ca + 2 AlBr₃ ----> 3 CaBr₂ + 2 Al

b) Single Displacement Reaction

2 Al + 3 MgSO₄ ----> Al₂(SO₄)₃ + 3 Mg

c) Double Displacement Reaction

AgNO₃ + KCl ----> AgCl + KNO₃

solong [7]

Answer:

Explanation:

Matter can be classified into two broad categories: pure substances and mixtures. ... A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound. For example, water is a compound composed of the elements hydrogen and oxygen.
