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
Percentage Weight-in-volume is defined as the <em><u>number of grams of a solute in a 100 ml (milliliters) solution.</u></em>
<u />
<u>Percentage Weight-in-volume</u> can tell us about the <em>degree of concentration of a given solution.</em>
<em><u /></em>
The solute can be <em>crystalline or non-crystalline in nature.</em>

The <u>number of grams of glucose</u> present in a <u>5% glucose solution</u> is 5 grams.
- This question is based on a Percentage Weight-in-volume. The formula states that:
a% of a glucose solution =<u> a grams of glucose in a 100 mL solution</u>
Hence, 5% glucose solution = 5 grams of glucose / 100 mL solution
Therefore, the <u>number of grams of glucose</u> present in a <u>5% glucose solution</u> is 5 grams.

The correct answer is C electron cloud.
Dalton said it was solid, Rutherford discovered nucleus and orbits like planets, Thompson had mass of negative material with positive "chips" in it
The statement that identifies an oxidation-reduction reaction is a reaction in which oxidation numbers change (option C).
<h3>What is a redox reaction?</h3>
A redox or oxidation-reduction reaction is a chemical reaction in which some of the atoms have their oxidation number changed.
In a chemical reaction that involves oxidation and reduction, the oxidation number of the involved ions either decreases or increases.
Therefore, the statement that identifies an oxidation-reduction reaction is a reaction in which oxidation numbers change.
