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:

Explanation:
Alcohols are organic compounds that are composed of the hydroxyl function group (
), bonded to a carbon atom of an alkyl or a substituted alkyl group. Hence, the functional group of alcohols is the hydroxyl group (
).
According to the International Union of Pure and Applied Chemistry (IUPAC) nomenclature, alcohols are named by changing the -<em>e</em> ending of the name of the parent alkane to the suffix <em>-</em><em>ol</em>.
For example, the alcohol molecule in the figure demonstrates a hydroxyl group bonded to a methyl group. Therefore, the name of the alcohol is methanol.
Your pattern of breathing increases, making it faster than usual, when you're exercising because you're pushing your body to work harder and speeding up your heart rate making you tired.
When you're resting your breathing pattern should be steady and normal since you aren't doing anything that requires lots of body work or something that would make you out of breath.
Hope this helps,

Answer: The results of Rutherford's gold foil experiment gave him the evidence to arrive at two conclusions: (1) an atom was much more than just empty space and scattered electrons and (2) an atom consists of a positive charge at the center where most of its mass is placed.
Explanation:
Ernest Rutherford performed an experiment in which he passed alpha particles through a thin gold foil sheet. Through this sheet some of the particles passed on to the other side but some of them were reflected back.
This experiment was done by Rutherford to prove than an atom contains a tiny and heavy nucleus. He concluded that an atom has more than empty space and electrons were present in scattered form.
Also, he concluded that an atom consists of a positive charge at the center where most of its mass is placed.
Thus, we can conclude that the results of Rutherford's gold foil experiment gave him the evidence to arrive at two conclusions: (1) an atom was much more than just empty space and scattered electrons and (2) an atom consists of a positive charge at the center where most of its mass is placed.
