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

Ответ:
64 kg
Explanation:
The computation of the number of kg need to ordered is shown below:
As we know that
Now as we know that
1 mole of
generated from 1 mole of ![CaC_2](/tpl/images/0747/6328/9e28e.png)
Now
26g of
generated from 64g of ![CaC_2](/tpl/images/0747/6328/9e28e.png)
And,
26kg of
generated from
=![\frac{64g\times26Kg}{26g}](/tpl/images/0747/6328/27735.png)
= 64kg![CaC_2](/tpl/images/0747/6328/9e28e.png)
Hence, the number of kg that required for ordering the calcium carbide is 64 kg
