When crossing parents with genotypes Rr and rr what will be the percentage of the genotypes of the offspring

Answer:

48.00

Explanation:

3 oxygen (15.99 x 3)= 48

Answer:

Titration 1=33.9ml

Titration 2=33.45ml

Titration 3=33.35ml

Explanation:

Volume of NaOH used =Final reading - Initial reading

Titration 1:

Final reading =35.5ml

Initial reading=0.6ml

Volume of NaOH used =34.5ml -0.6ml=33.9ml

Titration 2:

Final reading =34.3ml

Initial reading=0.85ml

Volume of NaOH used =34.3ml -0.85ml=33.45ml

Titration 3:

Final reading =33.8ml

Initial reading=0.45ml

Volume of NaOH used =33.8ml 0.45ml=33.35ml

Answer:

Explanation:

The volume (in mL) of 0.415M silver nitrate will be required to precipitate as silver bromide is 10.8ml , option B is the correct answer.

What is Molarity ?

Molarity is defined as the amount of solute (in moles)in per litre of solution.

It is also known as molar concentration of a solution , It is expressed in mol/l .

[tex]\rm M=\dfrac{n}{V}[/tex]

where n is the number of moles

and V is the volume in litres.

We can rearrange this equation to get the number of moles:

n= M * V

The molarity of calcium bromide is 0.064 M and the volume given is 35 ml,

the moles will be n = 0.064 * 35 = 2.24 moles

2AgNO₃(aq) + CaBr₂(aq) → 2AgBr(s) + Ca(NO₃)₂(aq)

From the reaction we can see that for every 1 mole of Calcium Bromide 2 moles of Silver Nitrate is needed , so for 2.24 moles 4.48 moles will be needed.

The molarity is given as 0.415 M and the number of moles is 4.48 so the volume required can be calculated from the above formula

[tex]\rm V=\rm\dfrac{n}{M} \\\\V=\rm\dfrac{4.48}{0.415} \\\\V= 10.8 ml\\[/tex]

Hence the volume (in mL) of 0.415M silver nitrate will be required to precipitate as silver bromide is 10.8ml , option B is the correct answer.

Answer:

A: Hydrogen bonding causes water to be strongly cohesive.

Explanation:

Water has a high surafce tension. Hence droplets of water

Water cannot dissolve non polar substances like oil; only polar

Water is actually less dense in solid form :)

Hydrogen bonding causes water to be strongly cohesive.

This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.

Cohesion, also called cohesive attraction or cohesive force, is the action or property of like molecules sticking together, being mutually attractive. It is an intrinsic property of a substance that is caused by the shape and structure of its molecules, which makes the distribution of surrounding electrons irregular when molecules get close to one another, creating an electrical attraction that can maintain a microscopic structure such as a water drop. In other words, cohesion allows for surface tension, creating a "solid-like" state upon which light-weight or low-density materials can be placed.

Answer:

The correct answer is - C. 0.500 mg.

Explanation:

In this case, the half-life of the iodine-131 is 8 days and the initial amount is given 4 mg. According to this after every 8 days, half of the initial value of the iodine-131 remains only.

8 days or 1st half-life = A(i)* 1/2

16 days or two half-life = A(i)* 1/4

24 days or three half-life = A(i)* 1/8

and the remaining amount A would be

= A(i)*1/2^n

= 4 * 1/2^3

= 4 *1/8

= 0.500 mg

Tipo de enlace enlace en H2O: enlaces covalentes y de hidrógeno

Electronegatividad de CO2 - Diferencia en electronegatividad de carbono (EN = 2.5) y oxígeno (EN = 3.5) = 3.5 - 2.5 = 1

Diferencia en electronegatividad de KCl = 3,2 -0,8 = 2,4

Answer:

electric charges.

Explanation:

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction.

An electron can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

An electric current is produced when electric charges (electrons) move continuously and it's measured in Amperes through the use of an ammeter.

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

[tex] V = IR[/tex]

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Answer:

High temperature increases the number of high energy collisions

Explanation:

Increasing the temperature a reaction takes place at increases the rate of reaction. At higher temperatures, particles can collide more often and with more energy, which makes the reaction take place more quickly.

Answer:

Water particles are close together and move slowly past each other

Answer:

The pH of the solution increases

Explanation:

One of the properties of metals is that they react with water to yield hydrogen gas and the hydroxide of the metal.

Calcium is a metal in group two of the periodic table and also undergoes such reaction.

The equation of the reaction is;

Ca(s) + 2H2O(l) -----> Ca(OH)2(aq) + H2(g)

Since Ca(OH)2 is alkaline, the pH of the solution increases.

Explanation:

Empirical formula is the simplest ratio of atoms present in a molecule. To solve this question we must find the moles of C, H and O in order to find the simplest ratio of this atoms.

To solve this question we must find the moles of C from CO2, moles of H from H2O and moles of O from the difference of masses of C and H and the sample:

Moles C:

1.64g CO2 * (1mol / 44g) = 0.03727 moles CO2 * (1mol C / 1mol CO2) = 0.03727 moles C

0.03727 moles C * (12g / mol) = 0.4473g C

Moles H:

1.01g H2O * (1mol / 18g) = 0.05611 moles H2O * (2mol H / 1mol H2O) =

0.1122 moles H

0.1122 moles H * (1g / mol) = 0.1122g H

Moles O:

0.860g - 0.1122g H - 0.4473g C = 0.3005g O * (1mol / 16g) =

0.01878 moles O

The ratio of the moles of atoms regard to the moles of O (Lower number of moles) is:

C = 0.03727 moles C / 0.01878 moles O = 1.98 ≈ 2

H = 0.1122 moles H / 0.01878 moles O = 5.97 ≈ 6

O = 0.01878 moles O / 0.01878 moles O = 1

Friendship is, in many respects, a "comfortable" love relationship. Friendships involve as little or as much intimacy as the partners are inclined to express at any given time. Friends are not normally obligated to exchange benefits, but do so in ways that are often so natural as to be unwitting. The ties that bind them are by unfettered mutual consent. In spite of its being so comfortable, in fact because of it, friendship contributes in unique ways .
