How can we obtain Salicyaldehyde? Give reactions also

Chemistry
1 answer:
Snezhnost [94]3 years ago
4 0

Salicaldehyde is formed by reimer Riemann reaction in which phenol and chloroform are heated together with sodium hydroxide or pottasium hydroxide yeild salicaldehyde.

C6H5OH+CH3Cl ----------> C7H6O2

KOH

It is also prepared by corresponding phenol by duff reaction.

A 300-gallon anaerobic digester will be loaded daily with a feedstock that contains two parts dairy manure and one-part water by
Mars2501 [29]

Answer:

The volume of feedstock needed to mantain an organic load rate of 2 kgVS/day is 0.055 m3/day of feedstock.

The HRT is 20.6 days.

Explanation:

First, we calculate how many kg is 1 m3 of feedstock. We know the density, so we can calculate the mass:

M=\rho*V=37.5\frac{lb}{ft^3}*1m^3*(\frac{3.281ft}{1m})  ^3=1324.5lb=600.7 kg

If the VS are 6% in weight,

M_{vs}=0.06*M=0.06*600.7\,kg/m^3=36,0kgVS/m3

The volume per day needed to feed 2 kg of VS/day is:

V=\frac{2kg}{36kg/m^3}= 0.055m3/day=5.5litres/day

The HRT depends on the volume of the tank and the flow. Its equation is

HRT=\frac{V}{Q}=\frac{300gal}{0.055 m^3/day}*\frac{1m^3}{264.172gal}\\   \\HRT=20.6\,days

g. What is crystallization?Name any two go mixtures that can be separated by this method:name any two mixtures that can be separ
Masteriza [31]

crystallization is a process which helps to separate a pure solid from a solution in its crystal form. This is the in use to purify solid. For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities.

Sugar and salt are examples of products where crystallization does not only serve as separation/purification technique, but where it is also responsible for getting crystals with the right size (and shape) for further application of the products.

Define: Atomic Mass, Mass Number, Isotope
Westkost [7]

Answer:

Explanation:

the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.

the total number of protons and neutrons in a nucleus.

to write the symbol for an isotope, place the atomic number as a subscript and the mass number (protons plus neutrons) as a superscript to the left of the atomic symbol

6 What is the main difference between a homogeneous mixture and a heterogeneous mixture?
tangare [24]
The best answer here is B , i.e. the components of a homogenous mixture are evenly distributed This means the constituents are mixed uniformly. In a heterogeneous mixture, the constituents are not mixed uniformly. Some good examples of a homogeneous mixture are: 1. Sugar solution 2. Soda 3. Water 5. soft drinks 6. Air 7. Vinegar 8. Brine Some examples of a heterogeneous mixture are: 1. Blood 2. Milk 3.Water and oil 4. Water and sand 5. Soil 6. Hollandaise sauce 8. smog
