Answer:
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 
Now
26g of generated from 64g of
And,
26kg of generated from
= 
= 64kg
Hence, the number of kg that required for ordering the calcium carbide is 64 kg
Answer:
See explanation
Explanation:
The structure of ethylene is shown in the image attached. The two carbon atoms have a double covalent bond between them.
The two carbon atoms are sp2 hybridized. The bond between them is a covalent bond, there is one pi bond and one sigma bond between the carbon atoms. Between carbon and hydrogen, there are covalent bonds also. The covalent bonds are sigma bonds.
The pi bonds between carbon atoms is weaker than the sigma bonds between the carbon atoms. This is because, the side-by-side overlap the p orbitals in a pi bond is less effective than the end-to-end overlap of a sigma bond.
Explanation:
D. The total mass of the reactants equals the total mass of the
products.
