Potential advantages of using water as a solvent in organic chemistry are:

Natural resource, easy to obtain, lower cost.
Avoiding biomass drying step.
Facilitating recovery of inorganics contained in biomass.

Disadvantages of using water as a solvent in organic chemistry

Higher critical point, severe reaction conditions.
Lower yields of water insoluble bio-oil.
The bio-oil with higher oxygen content and lower calorific value.

<h3>What is the most widely used liquefaction solvent?</h3>

Water is the most common liquefaction solvent. Not only is water an environmentally friendly solvent that is inexpensive and does not pollute the environment, but it also facilitates the recovery and recycling of inorganic matter contained in biomass in ionic form for eventual use as fertilizers.

<h3>Why is water called a universal solvent?</h3>

Water dissolves many substances and is known as a universal solvent. We learned that, despite being a universal solvent, it can only dissolve polar molecules and that nonpolar molecules, even when mixed with water, form a separate layer.
Many researchers around the world have studied the effect of liquefaction solvent type on the liquefaction behaviors of various biomasses, including lignocelluloses, algae, and sewage sludge.

What causes salinization

Svet_ta [14]

Answer:

Salinization is the increase of salt concentration in soil and is, in most cases, caused by dissolved salts in the water supply. This supply of water can be caused by flooding of the land by seawater, seepage of seawater or brackish groundwater through the soil from below.

4 Na + O2 → 2 Na2O<br><br> 6.79 moles of O2 will react to form how many moles of Na2O?

Nataly_w [17]

Answer:

13.94moles of Na₂O

Explanation:

The balanced reaction expression is given as:

4Na + O₂ → 2Na₂O

Given parameters:

Number of moles of O₂ = 6.97moles

Unknown:

Number of moles of Na₂O

Solution:

To solve this problem;

1 mole of O₂ will produce 2 moles of Na₂O ;

6.97 moles of O₂ will produce 6.97 x 2 = 13.94moles of Na₂O

T/F___ At the eutectic composition, an alloy can solidify at a constant temperature.___ For effective dispersion strengthening,

azamat

Answer:

TRUE
FALSE
TRUE
FALSE
FALSE
TRUE

Explanation:

At the eutectic composition, an alloy can solidify at a constant temperature : TRUE . this is because at eutectic composition the type of reaction that takes place there is invariant reaction in its thermal equilibrium
For effective dispersion strengthening, the dispersed phase should be needle-like, as opposed to round : FALSE. because the rounded shape will not cause a crack.
Intermetallic compounds are usually hard and brittle : TRUE. because Intermetallic compounds prevents dislocation movements and this makes them brittle and hard
For the effective dispersion and strengthening, the dispersed phase should be continuous : FALSE. this is because the dispersed precipitate must be small and not continuous
Stoichiometric intermetallic compounds exist over a range of compositions : FALSE
Faster solidification results in smaller interlamellar spacing : TRUE
