The mass of ethanol is consumed by the reaction of 3.37g oxygen gas is 4.85g

Explanation:

The balanced equation for the chemical reactions is;

CH₃CH₂OH + O₂ → CH₃COOH + H₂O

The mole ratio between oxygen and ethanol in the reaction is 1 : 1

The molar mass of O₂ is 32g / mole. Therefore the O₂ moles consumes in the reaction is;

3.37 / 32

If the molar mass of ethanol is 46.07g/mole, and the ration of reaction in 1 : 1; Then the moles of ethanol consumed is;

3.37/32 * 46.07

= 4.85g

hat is the percentage of water in the following compound? Answer using three significant figures. Sodium carbonate decahydrate,
BigorU [14]
You need to find the whole molar mass of the compound using the periodic table to add the values. 

Na2CO3= (2 x 23.0) + 12.0 + (3 x 16.0)= 106 g/mol
H2O= 10 x [ (2 x 1.01 ) + (16.0) ]= 180.2 g/mol

the total molar mass is 106 + 180.2 = 286.2 g/mol

the percentage of water you can find by doing "parts over the whole"

H2O%= 180.2 / 286.2 X 100= 63.0%

In the balanced chemical reaction for the combustion of acetylene (used in welding torches), determine at standard temperature a
Tpy6a [65]

Answer:

8L of CO2

Explanation:

The equation for the reaction is given below:

2C2H2 + 5O2 —> 4CO2 + 2H2O

From the equation above,

5L of O2 produced 4L of CO2.

Therefore, 10L of O2 will produce = (10 x 4)/5 = 8L of CO2

Therefore, 8L of CO2 is produce
