A. 3 purple and 1 white. :)
answer on EDGE2020. took/taking the exam.
Purple flowers are dominant over white flowers. The parent generation includes two heterozygous parents. The possible phenotypes of these parents’ offspring are 3 purple and 1 white. Therefore, option A is correct.
What do you mean by phenotype ?A person's genotype is their unique DNA sequence. This term is used to refer to the two alleles that a person inherited for a specific gene. A patient's clinical presentation is the detectable expression of this genotype.
We have three phenotypic classes with one locus and additive effects: AA, Aa, and aa.
Height, wing length, and hair color are all phenotypes. Phenotypes also include observable characteristics that can be measured in the lab, such as hormone levels or blood cell counts.
Purple flowers outnumber white flowers. There are two heterozygous parents in the parent generation. These parents' offspring could have three purple phenotypes and one white phenotype.
Thus, option A is correct.

According to Boyle’s law, when the pressure of a gas increases at constant temperature, its volume
Answer:
reduces
Explanation:
According to Boyle's law, when the pressure of a gas increases at constant temperature the volume reduces.
Boyle's law states that "the volume of fixed mass of a gas is inversely proportional to the change in pressure if the temperature is constant".
It suggests that at constant temperature, if pressure increases, temperature reduces.Mathematically, it is expressed as;
P1 V1 = P2 V2
P and V are pressures
1 and 2 are initial and finals state.
Boyle's law is stated for the ideal gas at a constant temperature. According to Boyle's law, with an increase in pressure, the volume of the gas decreases.
What is an ideal gas?The ideal gas is given as the gas in which the interatomic collisions are zero, and the changes are produced with the collisions to the walls.
Boyle's law is stated as the gas is at a constant temperature. According to the ideal gas, the pressure and volume are inversely related.
With the increase in pressure, the volume of the gas decreases and vice versa.

Andy rides a a speed of 8 miles per hour. How far does he ride in 3 hours?
Answer:
The answer is 24 miles.
Explanation:
Every hour he rides 8 hours. If he rides for three hours you can take 8 miles x 3 hours which is 24 miles.
The speed of the riding is 8 miles/hours . Within a time of 3 hours Andy will go for a distance of 24 miles.
What is speed?Speed is a physical quantity which measures the distance covered per unit time. The rate of speed is called velocity both having the units m/s, km/hr, miles/hr etc.
Speed is directly related to the distance covered. As the speed increases, distance covered by the object also increases. Whereas as the time increases, distance covered will decreases.
Given the speed of ride = 8 miles/s
time = 3 hours.
Distance = speed × time.
= 8 miles/ hr × 3 hours
= 24 miles.
Therefore, Andy will reach out a distance of 24 miles within 3 hours when ride with a speed of 8 miles/s.

Answer:
takes part in a chemical reaction
Explanation:
An atom is defined as the smallest part of an element that takes part in a chemical reaction.
When chemicals react, they simply exchange their atoms and recombine to form compounds where the atoms inside of them have a stable configuration.
In a chemical reaction, atoms are not broken down to simpler forms. Chemical reactions do now break down atoms. By losing, sharing or gaining of electrons, atoms simply form compounds and molecules.Choose the formula for ammonium.

Hi, I could really use your help. The question is Which of the products would you anticipate being formed in the least molar quantity? That is, which of the products (1, 2, or 3) is the minor product? Explain your choice. HINT: Consider the intermediates formed.
Answer:
Number 1 will be in the lowest molar quantity b/c formation of 1st order products are more difficult to form than secondary (#2) or tertiary (#3) substitution products.
Explanation:
In general, if a substitution occurs such that it is attached to a carbon that's attached to only one carbon, it is referred to as a primary carbon substitution. If a substitution occurs on a carbon that is attached to two (2) carbons, it is a secondary carbon substitution. Finally, if a substitution occurs such that it is attached to a carbon that's attached to three (3) carbons it is a tertiary substitution. Typically, primary substitution products follow an Sn2 type reaction pathway. Such requires the formation of only one intermediate that difficult to form as compared to 2° or 3° intermediates. Once formed, however, they will be very unstable and proceeds to product very quickly. Such produce very low product yield. The intermediates for 2° and 3° form more easily and are more stable in the reaction environments. An example is tertiary butyl halogens (e.g., t-butyl chloride) follow and Sn1 type reaction pathway forming a tertiary carbocation which then reacts with a nucleophile of choice and forms much higher yields than the 1° carbon substitution reactions. Suggest reviewing Sn2 and Sn1 substitution reactions.
For an aqueous solution of sucrose (C12H22O11), determine: (a) the molarity of 3.30 L of a solution that contains 225.0 g of sucrose M (b) the volume of this solution that would contain 4.30 mole of sucrose L (c) the number of moles of sucrose in 1.00 L of this solution mol C12H22O11
Answer:
a) Molarity = 0.199M
b) 21.6L of solution
c) 0.199 moles of sucrose in 1L
Explanation:
a) Molarity is the ratio of moles of solute (sucrose) in volume of solution (3.30L):
Moles sucrose -Molar mass: 342,3g/mol-:
225.0g * (1mol / 342,2965g) = 0.6573 moles
Molarity = 0.6573 moles / 3.30L
Molarity = 0.199Mb) 0.199M means 0.199 moles in 1L. 4.30 moles are in:
4.30 mol * (1L / 0.199mol) = 21.6L of solution
c) By definition, there are 0.199 moles of sucrose in 1L. This is the meaning of 0.199M
HOW TO CALCULATE MOLARITY:
The molarity of a solution can be calculated by dividing the number of moles of the substance by its volume. That is:Molarity (M) = no. of moles ÷ volumeQUESTION A:
Molar mass of C12H22O11 = 342.3 g/molno. of moles = 225g ÷ 342.3g/mol = 0.66molMolarity of sucrose = 0.66mol ÷ 3.30L = 0.2MQUESTION B:

To make 1 L of 1M soln needs 56g KOH
To make 500mL 1M needs 56/2 = 28g
To make 500mL 0.2M needs 28 x 0.2gn:
Explanation:
The weight of KOH are required to prepare 500. mL of 0.450 KOH solution is 12.6 gm
What is Molarity ?Molar concentration is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution.
In chemistry, the most commonly used unit for molarity is the number of moles per liter, having the unit symbol mol/L or mol/dm³ in SI unit.
Molar mass of KOH = 39 + 16 + 1 = 56g
To make 1 L of 1M soln needs = 56g KOH
To make 500mL 1M needs 56/2 = 28g
To make 500mL 0.450 M needs = 28 x 0.450
= 12.6 gm

According to stoichiometry and balanced chemical equation of iron and oxygen 17.15 g of rust is produced when 12 g iron reacts with oxygen.
What is stoichiometry?Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.
Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.
The balanced chemical equation for formation of rust when iron reacts with oxygen is,
4 Fe + 3 O₂[tex]\rightarrow[/tex] 2 Fe₂O₃
223.36 g of iron produces 319.38 g of rust
∴ 12 g iron will produce 12×319.38/223.36= 17.15 g of rust.
Therefore, 17.15 g rust is produced from 12 g iron when it reacts with oxygen.

If 1.0 mol of N2 and 3.0 mol of H2 in a closed container initially at STP react completely in the reaction shown below, then the final pressure in the flask will be ________ atm at 273 K.
Answer:
[tex]p_f=0.5atm[/tex]
Explanation:
Hello!
In this case, since the reaction between nitrogen and hydrogen produces ammonia:
[tex]N_2+3H_2\rightarrow 2NH_3[/tex]
We can compute the volume of the container by using the ideal gas law at STP (1 atm and 273.15 K):
[tex]V=\frac{4.0mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1atm}=89.7L[/tex]
Next, since nitrogen and hydrogen are in a 1:3 mole ratio, we understand all the nitrogen and hydrogen are consumed and only ammonia remains at the end of the reaction in the following amount:
[tex]n_{NH_3}=1.0molN_2*\frac{2molNH_3}{1molN_2} =2.0molNH_3[/tex]
Thus, the final pressure turns out:
[tex]p_f=\frac{2.0mol*0.08206\frac{atm*L}{mol*K}*273.15K}{89.7L}\\\\p_f=0.5atm[/tex]
