Answer:

They may have different phenotypes because of differences in their environments, such as nutrition and healthcare. Why might genetically identical twins have different phenotypes?  Any genes on the same chromosome could be linked genes, whereas only genes on sex chromosomes can be sex-linked genes.

Explanation:

Due to the effects of the environment, genetically identical twins might have different phenotype.

The qualities or visible characteristics of an organism are its phenotype. It depends on how the environment and the genotype, or genetic code, of the organism interact.

Although human monozygotic twins as well as other genetically identical species may share startling physical similarities, they frequently differ in key characteristics, such as complicated diseases. The effects of the environment have generally been blamed for this variance across organisms with essentially identical chromosomal DNA sequences.

Therefore, due to the effects of the environment, genetically identical twins might have different phenotype.

Colas are also carbonated beverages. The carbonation can produce some carbonic acid in the  Cola, which would affect your results. Therefore, to ensure that you are only titrating the  phosphoric acid you will use de-carbonated soda. This can easily be obtained by gently  heating the soda, or as you may already know, by rapidly shaking the bottle. It is also important that we do not use diet Colas since the artificial sweeteners that they contain have  acidic functional groups that will also interfere with the titration.

__________________________________________________________

Use a 25.00-mL pipet to deliver exactly 25.00 mL of room temperature, de-carbonated

Cola into a 250-mL beaker. Check out a magnetic stir bar and gently add it to the

beaker. Place the beaker on a stir plate. Set up a pH meter so that the probe is   completely immersed, but in a way that the stir bar will not hit it. The tip of the probe

has a thin glass membrane. Handle it with care! Position the beaker so that the stir bar

is as close to the center of the beaker as possible for optimal stirring. It should stir

rapidly enough to ensure thorough mixing but not so rapidly as to cause splattering.

__________________________________________________________

Obtain about 75 mL of 0.0100 M NaOH in a beaker. Use this NaOH to fill a buret.

Remember that you should always rinse a buret 2-3 times with the solution that you are

about to put into it and remove air bubbles at the buret tip. If you do not remember how

The initial level of the NaOH should be at exactly

0.00 mL. Once the buret is ready, place it over the beaker containing the Cola

Given

Skeleton equation(unbalanced equation) :

NaCl+F2⇒NaF+Cl2

Required

The number of atoms

Solution

We balance the reactions to find the reaction coefficient, which is then used to calculate the number of atoms in the reactants and products

Balanced equation

2NaCl + F2 → 2NaF + Cl2

A balanced reaction will show that the number of atoms in the reactants and products is the same

Na = 2 atoms

Cl = 2atoms

F = 2 atoms

Na = 2 atoms

F = 2 atoms

Cl = 2 atoms

Answer:

77460 g

Explanation:

To solve this problem first we convert molecules into moles, using Avogadro's number:

3.47x10²⁶ molecules ÷ 6.023x10²³ molecules/mol = 576.12 moles

Then we convert 576.12 CuCl₂ moles into grams, using its molar mass:

576.12 mol * 134.45 g/mol = 77460 g

So the answer is 77460 g, or 77.46 kg.

The orbital filling and electron configuration are based on various principles. The Aufbau principle states that electrons fill the orbital from lowest to highest energy levels. Thus, option A is correct.

The Aufbau principle is the rule that states about the filling of the electron in the various orbitals of an atom. It defines the filling of the lower atomic orbitals before the higher levels are filled.

This principle allows for determining the electronic configuration of the atom. The rule states that the electron first occupies the lowest energetically unrestricted orbits that can hold a certain number of electrons. The electron can only move to a higher level when the electron is filled in the previous subshell.

Therefore, option A. the Aufbau principle gave the filling of electrons in the lowest energy level.

Answer:

The density of substance A is more.

Explanation:

Given that,

The density of a substance is 5.4 g/cm³.

The density of another substance is 5.4 kg/m³.

We need to find a substance that has a greater density.

First, we make the units the same.

1 kg = 1000 g

1 m = 100 cm

5.4 kg/m³ = 0.0054 g/cm³

Now, if we compare 5.4 g/cm³ and 0.0054 g/cm³, we find that the density of substance A is more.

Answer:

Explanation:

Thus, if we have 6.022 × 10 23 O atoms, we say we have 1 mol of O atoms. If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms. Similarly, if we have 0.5 mol of benzene (C 6H 6) molecules, we have 0.5 × (6.022 × 10 23) C 6H 6 molecules, or 3.011 × 10 23 C 6H 6 molecules.

For example the atomic mass of methane (CH4)is 12 amu for the carbon plus 4 x 1 amu for the four hydrogens, for a total of 16 amu. Therefore the molar mass of methane is 16g. We say that one mole of methane has a mass of 16 g, and that there are 6.022 x 1023 atoms in that mass of methane.

The number of atoms present in 0.75 mole of methane, CH₄ is 4.515×10²³ atoms

1 mole of CH₄ = 6.02×10²³ atoms

From Avogadro's hypothesis, we discovered that:

1 mole of CH₄ = 6.02×10²³ atoms

Therefore,

0.75 mole of CH₄ = 0.75 × 6.02×10²³

0.75 mole of CH₄ = 4.515×10²³ atoms

Thus, 4.515×10²³ atoms are present in 0.75 mole of CH₄

Answer:

The melting/boiling point of a substance determines what state of matter it takes at a certain temperature.

In Cl2 there are covalent bonds between the atoms forming simple molecules. There are weak attractions between molecules of Cl2 meaning little energy is needed to break these forces of attraction and therefore Cl2 has a low boiling point.

NaCl on the other hand has strong electrostatic forces of attraction between the positvely charged Na ion and the negatively charged Cl ion. NaCl forms a giant ionic lattice that requires high amounts of energy to break and therefore has a high melting point.

Explanation:

Write the name of the cation, and then write the name of the anion, changing the ending to "-ide" if it's a single element and leaving it as it is if it's a polyatomic ion.

Sample Response: No, thermal energy is not being transferred by radiation in this image. The eggs are in direct contact with the metal pan, which is in direct contact with the gas flame, so this is conduction, not radiation. Radiation transfers thermal energy by electromagnetic waves, not by direct contact.

Explanation:

No, thermal energy is not being transferred by radiation in this image.

The eggs are in direct contact with the metal pan, which is in direct contact with the gas flame.

Thermal energy is being transferred by conduction.

Radiation transfers thermal energy by electromagnetic waves.

Radiation does not transfer thermal energy by direct contact.

Thermal energy is the heat energy that is produced with an increase in temperature. No, thermal energy is not transferred by radiation when eggs are cooked.

Radiation is the process of thermal energy transfer that emits heat in all directions and does not require an intervening medium to travel.

Thermal energy is not transferred by radiation in the image as the eggs are in contact with the pan and the pan is in direct contact with a flame that radiates the heat by conduction.

Therefore, heat transfers by conduction and not by radiation.
