C.Dissolve because its another word for soluble
<span>I think we can use rovers, landers, orbiters, probes and satellites.
Hoped this helped</span>
Answer:
Check the explanation
Explanation:
Here, Nitrogen (N) undergoes oxidation and Chlorine (Cl) undergoes reduction.
To answer your question:
N is oxidized from an oxidation number of -3 to an oxidation number of -1.
Cl is reduced from oxidation number of +1 to an oxidation number of -1.
Now,
Borneol should have a lower Rf because of boiling point.
The formula mass of MgCl - atomic mass of Mg + 2(atomic mass of Cl)
formula mass - 24.3 + (35.45x2) = 95.2
In 95.2 of MgCl₂ - there are 6.022 x 10²³ formula units of MgCl₂
Therefore in 15.0 g of MgCl2 - there are 6.022 x 10²³ /95.2 x 15.0 = 9.49 x 10²² formula units of MgCl₂
the number of formula units - 9.49 x 10²² formula units of MgCl₂
Moles of Na theoretically extract : 10.256
<h3>Further explanation</h3>
Given
600 g of NaCl
Required
moles of Na
Solution
Na can be electrolyzed from NaCl(molten)
Na⁺ + e⁻⇒ Na
Cl⁻⇒1/2 Cl₂ + e⁻
Overall reaction :
NaCl⇒Na + 1/2 Cl₂ x2
<em>2NaCl⇒2Na + Cl₂</em>
mol of NaCl(MW=58.5 g/mol) :
= 600 g : 58.5 g/mol
= 10.256
From the equation, mol ratio of NaCl : Na = 2 : 1, so :
mol Na = mol NaCl = 10.256
