Answer is: volume of CO₂ is 0,113 dm³.
Ideal gas law = pV = nRT.
p = 850 PSI = 5860543,6992 Pa.
Psi <span>is the abbreviation of pound per square inch.
T = 21</span>°C = 294,15 K.
n = 0,273 mol.
R = 8,314 J/K·mol.
V = nRT ÷ p
V = 0,273 mol · 8,314 J/K·mol · 294,15 K ÷ 5860543,6992 Pa.
V = 0,00011 m³ = 0,113 dm³.
Reacting nitrous acid with aromatic amines to produce diazonium salt is one of the most used processes. An aromatic amine called aniline reacts with nitrous acid to generate benzene diazonium chloride, a diazonium salt.
To create azo colors, benzene diazonium chloride combines with phenol, -napthol, aniline, and 2-methylaniline. These reactions result in the removal of an HCl molecule. Red organic dye is created when benzene and benzene diazonium chloride interact. Since the solutions created in this method do not last, the reactions involving a diazonium salt are always carried out with a freshly prepared solution. Diazonium salts are very flammable when they are solid because of their instability.

Tungsten (W) has an atomic number 74
The nearest noble gas to tungsten in the periodic table is Xe which has atomic number of 54.
Therefore, the configuration of W using the noble gas Xe will be as follows:
<span>[Xe] 4f14 5d4 6s2</span>
Answer:
The correct answer would be -
17. 50% chances of round offspring
18. 25% chances two copies of dominant allele in the genotype of offspring
Explanation:
17. In this question it is stated that the Spongebob is heterozygous and has a square body which means the square body is dominant over the round that is present in sponge Susie that means she has two copies of the recessive allele.
S for square trait and s for a round trait then
S s
s Ss ss
s Ss ss
Thus, the correct answer is 50 percent as there are only two copies of ss.
18. in this question Patric and Patti both have heterozygous for the pink (P) body-color dominant over yellow (p). The chances for the true-breeding dominant genotype would be -
P p
P PP Pp
p Pp pp
There is only one out of four rue-breeding dominant offspring will be produced.
Answer:
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶
Explanation:
Iron is soft, bright white metal.
Its symbol is Fe, atomic number is 26 and atomic mass is 55.85 amu.
It is present in group 8 of periodic table.
It is used to make the steel.
It is malleable and ductile used to make the sheets.
It is good conductor of heat and electricity because of moveable electrons that can easily move from one to another atom.
Its density is 7.87 g/cm³.
Electronic configuration:
Fe₂₃ = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶
Abbreviated electronic configuration:
Fe₂₃ = [Ar] 3d⁶4s²
