Answer:
genetics i.e the law of heredity
Answer:Mendel proposed three laws: Law of Dominance. The Law of Segregation. Law of independent assortment.
Explanation:Gregor Johann Mendel was a scientist who is recognized as the Father and Founder of genetics. Mendel conducted many experiments on the pea plant (Pisum sativum) between 1856 and 1863. He studied the results of the experiments and deducted many observations. Thus, laws of inheritance or Mendel’s laws of inheritance came into existence. Before learning about Mendel’s laws of inheritance, it is important to understand what the experiments performed by Mendel were.

You have been handed a 1892.6g sample of Rion and determine that it has
a volume of 200.0 mL. What is the density of Rion?
Answer:
9.46 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 1892.6 g
volume = 200 mL
We have
[tex]density = \frac{1892.6}{200} \\ = 9.463[/tex]
We have the final answer as
9.46 g/mLHope this helps you

why does the reaction of anthracene with maleic anhydride needs to be kept away from water?
Answer:
Water separates the two reactants into two layers, stopping the reaction.
Explanation:
Maleic anhydride can and will react with water.
The reaction between maleic anhydride and anthracene is a Diels Alder reaction. This type of reaction is a cycloaddition reaction.
What is Diels Alder reaction?The Diels Alder reaction is a member of a class of reactions called cycloadditions. This reaction involves three pi bonds, two from the diene and one from the dienophile in a concerted reaction to give a six-membered ring.
Since this reaction involves four pi electrons in the diene and two pi electrons from the dienophile, it is sometimes referred to as a 4+2 cycloaddition.
The presence of electron donating groups on the diene and the electron withdrawing groups on the dienophile favors normal Diels Alder reactions. The reaction involves the formation of new σ bonds which are energetically more stable than π bonds.
Anthracene can react with water, breaking the center ring. Maleic anhydride can react with water, opening its ring. The reactants get seperated into two layers by water and thereby stops the reaction.

Explanation:
A nickel compound has the formula Ni(NO3)2•xH,0 and a molar mass
of 290.7 g mol-1. Calculate the value of x.
Someone tell me the method for this
Explanation:
Molar mass of a compound is the sum of the molar mass of all the atoms of the compound.
⇒ Molar mass of the Nickel Compound (Hydrated Nickel (II) Nitrate)
= Molar mass (Ni+ 2N + 6O)+ x (2H+ O)
= [58.693 + 2(14.007) + 6(15.999)] + x [2(1.008) + 15.999] g/mol
= (182.701 + 18.015x) g/mol
Since the molar mass is known to be 290.7 g/mol
then 182.701 + 18.015x = 290.7
⇒ 18.015x = 290.7 - 182.701
x = (290.7 - 182.701) ÷ 18.015
∴ x = 6 [conventionally expressed as a whole number]
that makes the compound Nickel Nitrate Hexahydrate
The value of x in the hydrated compound of nickel nitrate with molecular mass 290.7 g/mol is 6.
What is the molecular mass?Molecular mass can be defined as the sum of the mass of each element in the compound.
The molecular mass of the given compound is 290.7 g/mol. The value of x in the compound can be given as;
[tex]\rm 290.7\;g/mol=2(Ni)+2(N)+2(3O)+x(2H+O)[/tex]
Substituting the mass of N, Ni, O and H for the calculation of x as:
[tex]\rm 290.7\;g/mol=(58.693)+2(14.007)+2(3(15.999))+x(2(1.008)+15.999)\\290.7=182.701+18.015x\\x=6[/tex]
The value of x in the hydrated compound of nickel nitrate is 6.

What is titration?Titration is a typical quantitative chemical analysis procedure used in laboratories to quantify the concentration of a specified analyte. The titrant or titrator is a substance that is manufactured as a standard solution with a given concentration as well as volume.
Permanganate titrations must be performed in a strong acid solution. Because [tex]HNO_{3}[/tex] and HCl might involve in competing for a redox reaction, lowering the accuracy of the titration, sulfuric acid is commonly utilized. Titration permits food manufacturers to calculate the amount of a reactant present in a sample.
