Volume of Fe(NO₃)₃ = 5.00 ml
Total voluem of the solution = 20.0 ml
Concentration of Fe(NO₃)₃ = 0.002 M
Assuming complete dissociation of Fe(NO₃)₃ concentration of Fe³⁺ = 0.200 M
Using the dilution equation, M₁V₁ = M₂V₂
where M₁ and M₂ are the initial and final concentration of Fe³⁺ respectively and V₁ and V₂ are the initial and final volume of Fe³⁺ respectively
Plugging the data we get,
M₂ = 
= 5 x 10⁻⁴
Therefore, the concentration of Fe³⁺ once diluted in the mixture is 5 x 10⁻⁴M
A Diatom is under the phylum of Chrysophyta with the following characteristics:
1) Unicellular but often colonial
2) manufactures the carbohydrate chrysolaminarin
3) has unique double -shells of opaline silica
4) contains chlorophylls a and c
They are abundant in sea and fresh water where they serve as producers.
Diatoms are protists that have glass walls. Just like plants, they carry out cytokinesis. They are photosynthesizers with hard shells of silica. An example of a Diatom is Diatoma.
Diatoms are divided into two major groups, one with radial symmetry and the other with bilateral symmetry.
Answer:
Total protein range. The normal range for total protein is between 6 and 8.3 grams per deciliter (g/dL). This range may vary slightly among laboratories.
Explanation:
Answer:
The compound which are boh soluble in water and hexane is
B. Ethanol and 1-propanol
Explanation:
The compounds ethanol and 1-propanol are soluble in both hexane and water.
It is soluble in water as both consists of polar end due to hydrogen bonding present in the -OH functional group.
and both are soluble in hexane as they contain a non polar end and the alliphatic hydrocarbon chain in them.
The solubility of alcohols varies in increasing order as the hydrocarbon chain increases. And becaue of this it becomes more non polar.
Non polar properties decreases for branched molecules.
so, the correct option is ethanol and 1-propanol.
A molecule that can h-bond will not always necessarily and does not have guarantee to have a higher boiling point than one than cannot have h-bond.
we can take an example of Pentan-2-one that cannot h-bond but instead of this it has a high boiling point that is 102.3 °C, while propan-1-ol can h-bond but it has a boiling point of 97.2°C, that is lower than the boiling point of Pentan-2-one.
