Answer:
Solid KOH will corrode the skin but a solution of KOH in triethyleneglycol will not.
The temperature is monitored with an external thermometer also because the sand looses some heat to energy exchange with the surrounding.
Explanation:
KOH is a deliquescent solid which is very corrosive upon contact with skin. Its solution in an organic liquid is not corrosive.
Secondly, when exposed to the surrounding, heat is lost according to the laws of thermodynamics.
Answer:
One quart.
Explanation:
Let us consider the relation between all of the given units of volume and one litre.
a) one litre equals to 33.84 ounces
b) one litre equals to 2.11 pint
c) one litre equals to 0.95 quart
d) one litre equals to 4.54 gallons
Thus from above conversions it is clear that one litre is almost equal to or about 1 quart (0.95 approxes 1).
Number of moles of NO2 = 11.5/(14+16x2) =0.250mol
Mole ratio: 4NO2 to 1O2
Number of moles of O2=0.250/4 =0.0625mol
Mass of O2 produced= 0.0625x32 =2g
Answer: B
Answer:
An example of a metal with an organic radical is: Pentamethylcyclopentadiene, which is the union between Zinc and an organic compound, where in order to obtain it there is a release of dihydrogen.
Another example is lead tetraethyl, it is a compound for industrial use, it is dangerous for the human body, toxic and can be used as fuel.
Explanation:
In radical chemistry a chemical species is called both organic and inorganic, which one of the most used examples is methyl, where it is a chemical structure that has one carbon and 4 hydrogens attached to this central carbon.
These chemical compounds when united with metals, release one of the unions that they have with hydrogens, it is because in reactions they release hydrogens.
The image on the left has been split in half to reveal the five spherical nodes that make up the 5s orbital. The nodal structure of the 5s-orbital is seen in the shape on the right. The higher s-orbitals ( 6s and 7s), while still spherical, are more complicated since they feature more spherical nodes.
