Na is the elemental abbreviation for sodium, and Cl is the abbreviation for chlorine.
When the two are combined, you get sodium-chloride, or table salt.
Hope that helped =)
Answer:
Explanation:
Molal freezing point depression constant of butanol Kf = 8.37⁰C /m
ΔTf = Kf x m , m is no of moles of solute per kg of solvent .
mol weight of butanol = 70 g
235.1 g of butanol = 235.1 / 70 = 3.3585 moles
3.3585 moles of butanol dissolved in 4.14 kg of water .
ΔTf = 8.37 x 3.3585 / 4.14
= 6.79⁰C
Depression in freezing point = 6.79
freezing point of solution = - 6.79⁰C .
Given:
Number of items = 25
Price per item = $18
<u>To determine:</u>
The total revenue
<u>Explanation:</u>
Total revenue = quantity * price per item
= 25 items * 18 dollar/ 1 item = $450
Ans: A) The total revenue is $450
Water
hydrogen ions+hydroxide=water
which can be verified by dark reaction of photosynthesis
