NeTakaya3 years ago
5 0

Answer:

c2h4o2

Explanation:

I am using my cell. This could take a bit

The Empical formula has a mass of

C 12

2H 2

O 16

total = 30

The molecular mass is given as 60 which is 2 times the empirical mass. Therefore multiply each element by 2 in the empirical formula.

You get C2H4O2

Write the chemical equation for the following reaction: the elements carbon and oxygen combine to yield the compound carbon diox
Marta_Voda [28]
Product of this reaction depends on the amount of oxygen. i.) If oxygen is excess: Carbon, as graphite, burns to form gaseous carbon (IV) oxide (carbon dioxide), CO2 Equation : C + O2 ----> CO2. This reaction is also called combustion reaction. The expensive way to produce CO2 is to burn Diamond in the presence of air at 600-800°C. Hope it helped you. :D

If 1.00 g of reactant a is mixed with 2.00 g of reactant b, what is the theoretical yield of product d, in grams (g)? the molar
WARRIOR [948]

The chemical reaction is as follows:

a+b\rightarrow d

Mass of reactant a is 1 g and molar mass is 94 g/mol. Converting mass into number of moles as follows:

n=\frac{m}{M}=\frac{1g}{94 g/mol}=0.0106 mol

Now, 1 mole of reactant a gives 1 mole of product d thus, 0.0106 mol of reactant a gives 0.0106 mol of product d.

Molar mass of product d is 125 g/mol, converting number of moles into mass as follows:

m=n×M=0.0106 mol×125 g/mol=1.33 g

Similarly, molar mass of reactant b is 118 g/mol and mass is 2 g, converting mass into number of moles,

n=\frac{m}{M}=\frac{2g}{118 g/mol}=0.017 mol

1 mol of reactant b gives 1 mol of product d thus, 0.017 mol will give 0.017 mol of product d.

Converting number of moles into mass as follows:

m=n×M=0.017 mol×125 g/mol=2.12 g

Here, reactant that produces lesser product is limiting reactant and the amount of product it forms is theoretical yield.

Therefore, theoretical yield is 1.33 g.
