Acetylene gas, C2H2, releases large quantities of heat when it burns, making it ideal for welding applications. This gas is gene

rated by reacting calcium carbide with excess water. Calcium hydroxide is a byproduct of this reaction. If you needed 26kg of acetylene to fill a cylinder, how many kg calcium carbide would you need to order?

Answer:

64 kg

Explanation:

The computation of the number of kg need to ordered is shown below:

As we know that

CaC_2 + 2H_2O \rightarrow Ca(OH)^2   + C_2H_2

Now as we know that

1  mole of C_2H_2 generated from 1 mole of CaC_2

Now

26g of C_2H_2 generated from 64g of CaC_2

And,

26kg of C_2H_2 generated from

= \frac{64g\times26Kg}{26g}

= 64kg CaC_2

Hence, the number of kg that required for ordering the calcium carbide is 64 kg

Molecular Formula of Propanoic Acid is....

                                                C₃H₆O₂
Where;

Atomic Mass of C  =  12

Atomic Mass of H  =  1

Atomic Mass of O  =  6

Substituting Atomic Masses in molecular formula,

                                                (12)₃ + (1)₆ + (16)₂

                                                   36  +  6  +  32

                                                        74 g/mol

Result:
            
Molecular Mass of Propanoic Acid is 74 g/mol. Structure of Methyl Ethanoate and Propanoic Acid are as follow,
