Answer:

1.1445g

Explanation:

Mass of Zn = 2.0g

Mass of CuSO4 = 2.0g

Molar mass of Zn = 65.4g/mol

Molar mass of CuSO4 = 159.5g/mol

No. Of moles = mass / molar mass

No. Of moles of Zn = 2.0/65.4 = 0.030moles

No. Of moles of CuSO4 = 2/159.5 = 0.0125 moles

Equation of reaction

CuSO4 (aq) +Zn(s)-> ZnSO4(aq) + Cu(s)​

Stoichiometric molar ratio of CuSo4 : Zn = 1:1

Actual molar ration of CuSO4 : Zn = ?

0.0125 / 0.030 = 1 / 2.4

Zn is present in excess in the reaction, while CuSO4 is the limiting reagent

1 mol of CuSO4 = 1 mol of Zn

0.0125 moles of CuSO4 = 0.0125 moles of Zn

No. Of moles left after reaction = 0.030 - 0.0125 = 0.0175 moles.

Mass = no. Of moles * molar mass = 0.0175 * 65.4 = 1.1445g

The mass of Zn left after the reaction is 1.1445g.

2. The empirical formula of a molecule is CH2O. In an experiment, the molar mass of the molecule was determined to be 360.3 g/mo
Vanyuwa [196]

Answer:

The answer to your question is:

2.- C₁₂ H₂₄ O₁₂

Explanation:

2.-

Data

CH2O

molar mass = 360.3 g/mol

Molar mass of CH2O = 12 + 2 + 16 = 30g

Divide molar mass given by molar mass obtain

                   

                           x = 360.3/30

                          x = 12

Finally

                      C₁₂ H₂₄ O₁₂

Molar mass = (12 x 12) + (24 x 1) + (16 x 12) = 144 + 24 + 192 = 360 g

3.- First we need to write the complete equation of the reaction and balanced it.

Then, we need to convert the mass given to moles of each compound.

After that, we need used rule of three calculate the amount of products based on the moles of reactants given.

Finally, convert the moles to grams.

4.-

a.- It is a relation between the mass of product obtain in an experiment and the mass of a product obtain theoretically times 100.

b.-

35 g of Mg reacted with excess O2

percent yield = 90%

Actual yield = ?

Formula

Percent yield = (actual yield/theoretical yield) x 100

Equation  

                       2Mg  + O2 ⇒ 2MgO

                      48.62 g of Mg ----------------- 80.62 g of MgO

                      35g                  ------------------  x

                     x = 58 g of MgO     (Theoretical yield)

Theoretical yield = 58 g of MgO

Actual yield = percent yield x theoretical yield / 100

                    = 90 x 58 / 100

                   = 52. 23 g

Many protists are single-celled organisms. Which of the following characteristics is also common to organisms in Kingdom Protist
HACTEHA [7]

Protists belong to the group eukaryotes (having their DNA enclosed inside the nucleus). They are not plants, nimals or fungi but they act like one. They can be in general subgroups such as unicellular algae, protozoa and molds. They thrive in environments with little sunlight. The answer is letter B.
