Answer:

Mechanical weathering is usually caused by extreme hot and cold temperatures. Water seeps into cracks in rocks, freezes, and expands, causing further breakdown of rocks. Wind is another example of mechanical weathering.

That is, the molar mass of a substance is the mass (in grams per mole) of 6.022 × 10 23 atoms, molecules, or formula units of that substance. In each case, the number of grams in 1 mol is the same as the number of atomic mass units that describe the atomic mass, the molecular mass, or the formula mass, respectively.

Answer:

Dispersion forces are the weakest intermolecular force (one hundredth-one thousandth the strength of a covalent bond), hydrogen bonds are the strongest intermolecular force (about one-tenth the strength of a covalent bond). Dispersion forces < dipole-dipole interactions < hydrogen bonds.

Answer:There are two kinds of forces, or attractions, that operate in a molecule—intramolecularand intermolecular. Let's try to understand this difference through the following example.

Figure of towels sewn and Velcroed representing bonds between hydrogen and chlorine atoms

We have six towels—three are purple in color, labeled hydrogen and three are pink in color, labeled chlorine. We are given a sewing needle and black thread to sew one hydrogen towel to one chlorine towel. After sewing, we now have three pairs of towels: hydrogen sewed to chlorine. The next step is to attach these three pairs of towels to each other. For this we use Velcro as shown above.

So, the result of this exercise is that we have six towels attached to each other through thread and Velcro. Now if I ask you to pull this assembly from both ends, what do you think will happen? The Velcro junctions will fall apart while the sewed junctions will stay as is. The attachment created by Velcro is much weaker than the attachment created by the thread that we used to sew the pairs of towels together. A slight force applied to either end of the towels can easily bring apart the Velcro junctions without tearing apart the sewed junctions.

Exactly the same situation exists in molecules. Just imagine the towels to be real atoms, such as hydrogen and chlorine. These two atoms are bound to each other through a polar covalent bond—analogous to the thread. Each hydrogen chloride molecule in turn is bonded to the neighboring hydrogen chloride molecule through a dipole-dipole attraction—analogous to Velcro. We’ll talk about dipole-dipole interactions in detail a bit later.

Answer:

1.mass of Ag3PO4=4185.8g

2.mass of AgBr=6732g

Explanation:

Let the mass of the compound be 100g.

Mass of Sulfur = 96g.

=> Moles of Sulfur

= 96g / (32.07g/mol) ≈ 3

Mass of Hydrogen = 4g.

=> Moles of Hydrogen

= 4g / (1.008g/mol) ≈ 4

Mole ratio of Sulfur to Hydrogen = 3 : 4,

Empirical formula of compound = S3H4.

Empirical formula is the simplest whole number ration of elements in a compound. Molecular formula is n times where n is integers 1,2,... Therefore, S[tex]_3[/tex]H[tex]_4[/tex] is the empirical formula of a hypothetical compound that is 96%S and 4% H.

Empirical formula gives the proportion of the element that is present in a compound. It does not give information about the actual number or the arrangements of the atoms.

Answer:

3 atoms

Explanation:

The number of atoms of the metal that would be required as it forms an anionic charge of -3 is 3 atoms.

Elements in group 1 generally have a charge of +1. They have a valency of 1

By the virtue of this;

 It will take 3 atoms of a group one element to combine with an anion with a -3 charge on it.

This way, the ionic bond forms and the compound becomes neutral.

Answer:

Where are the following words.

Answer: The covalent bonds within a molecule are very (strong). However it requires (less) energy to melt a molecular compound than an ionic compound.

This is because the attractive forces between individual molecules are (weaker) than the forces between ions in an ionic compound.

The term chemical bond generally refer to the attractive force which holds the respective ions or atoms of a molecular substance. Bonding in the compounds helps to attain the stability.

A bond which is formed by the sharing of an electron pair among the atoms is known as the covalent bond. The concept of covalent bond was introduced by G.N Lewis in 1916.

An ionic bond is generally formed by the transfer of one or more electrons from one atom to another. In an ionic bond the positive and negative ions are held together by the electrostatic forces of attraction.

The ionic compounds have high melting and boiling points and in order to break the ionic bonds there is a need to supply large amount of energy than the covalent bonds. Thus ionic compounds are found to be stronger than the covalent compounds.

The covalent bonds within a molecule are (very strong) and it requires (less) energy to melt a molecular compound.  The attractive forces between individual molecules are (weaker) than the forces between ions in an ionic compound.

2. It will be easier to remove beryllium's valence electrons. Beryllium has two valence electrons, while oxygen has six valence electrons. This means that oxygen has a greater attraction on its electrons because the protons and electrons are closer together. Moreover, during bonding, beryllium is more likely to form the cation Be^2+ and oxygen is more likely to form the anion O^2-. This shows that due to beryllium's weaker attraction, it is more likely to get its electrons taken away than oxygen is.

Explanation:

1. Complete each of the orbitals up to each of the desired elements. Look up a diagram showing the electron shells of the periodic table and count the electrons of each element to be able to solve any configuration problem.

Another way of writing the answer would be in noble gas configuration. This would change the answer to:

Cl: [Ne] 3s^2 3p^5

Ag: [Kr] 5s^2 4d^9

But both answers (the extended electron configuration and the noble gas configuration) mean the same thing.

Answer:

B

Explanation:

Because the electrons are greater than the protons which makes the atom negative charged.

And when you minus 6-8=-2

Hope this helped!

The charge of an atom with 6 protons and 8 electrons is -2. Because the number of electrons dominates by 2 units.

Atoms in their neutral state have equal number of electrons and protons. Electrons are negatively charged particles and protons are positively charged particles.

Hence, all the positive charges are neutralized with equal number of negative charges. When atoms loss or gain electrons they gets charged and this charged atom is called ions.

When electrons dominates in number or atoms gain electrons they acquire negative charge and form anions. Similarly if atoms loss  electrons they form positive ions.

Here, the number of electron is 2 greater than protons. Hence the charge of the atom is -2.

Observations are defined as a set of statements or facts which are recorded while conducting an experiment.Observations are made through sensing changes in the variables of the experiment.

It is specifically defined as an act of knowing or recording the changes in the variables of the experiment.Recording observations holds importance as recording observations avoid the experiment to be repeated over and over again.

It is important to note down observations so that the testing of hypothesis is made easier.There are four types of observations .Observations need to be descriptive and must be written in complete sentences and should include all the numerical data of the experiment.

Answer:

4

Explanation:

Given that:

a valence shell of an atom = 32 electrons. This seems to be an atomic element known as germanium. At the outer shell, the number of electrons for germanium is 4. Degenerate orbitals are usually known to be orbitals that possess the same energy.  According to the Aufbau principle, the electron filling of germanium (32 electrons) = [Ar]  4s² 3d¹⁰ 4p². So, the number of a degenerate atom of 32 electrons = 4

Answer:

C

Explanation:

When the electron is greater than proton the atom will be negatively charged.
