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.

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.

Answer:

To name an ionic compound, you simply need to find the names  of the cation and anion present in the compound and make sure to revise the ends of metal names as needed. First, write out the name of the metal, followed by the name of the non-metal with its new ending.

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.

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:

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

Moles of Iron : 1.01

Given

Reaction

Fe2O3 + 3CO → 2Fe + 3CO2

34 liters of CO

Required

moles of Iron

Solution

Assumed at STP

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

so for 34 L :

= 34 : 22.4

= 1.518 moles

From the equation, mol Fe :

= 2/3 x moles CO

= 2/3 x 1.518

= 1.01 moles

Explanation:

Because gold is its own element, a gold bar is only made of one element.

The smallest unit found in a bar of gold is the nucleus of its atom.  The core of an atom is called its nucleus which contains the nucleons protons and neutrons.

An atom is composed of  nucleons and electrons. The core of an atom is called its nucleus. Protons and neutrons are located inside the nucleus. They are called the nucleons.

The electrons are revolving around the nucleus through circular trajectories of fixed energies. Every elements are composed of their atoms. Atoms of different elements combine together to form compounds.

Gold is 79th element in periodic table. It is a transition metal in d-block. As every other elements the smallest unit are atoms where the atomic nuclei are even smaller units.

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.
