Answer:

Explanation:

When I was growing up, one of the most popular cartoons was a little possum whose name was Pogo. He often said

“We have met the enemy and he is us.”

It is something Pogo said more than once. We are the problem with biodiversity being threatened.

We clear land for agriculture, not only in Canada and the United States, but in places like Brazil where it matters what is done to the environment. Those trees are the planet's lungs. Whole environmental groups are devoted to stopping the harvesting of trees that are hundreds of years old.

Our oceans have become cesspools of plastic.

Our rivers have become dumping grounds for all kinds of pollutants like paint and car tires to name just a couple.

Our landscape has been cluttered by billboards advertising things that are hundreds of miles away.

There's mining, oil, and other industries that make Mother Nature shudder every time they come near her.

✯Correct Answer✯:

The correct answer that you are looking for would be:  

B.) Habitat loss

♪Explanation♪:

Habitat loss answer option is correct because removing trees deprives the forest of portions of its canopy, which blocks the sun’s rays during the day and retains heat at night. That disruption leads to more extreme temperature swings that can be harmful to plants and animals. Yet the effects of deforestation reach much farther, it is very sad for the environment ＞﹏＜.

Answer:

True

Explanation:

Material resources are materials found in the natural world that have practical use and value for humans. Material resources include wood, glass (which comes from sand), metals, edible plants, and plastics (which are made from natural chemicals). Renewable material resources, like glass, can be re-created easily.

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.

Answer:

When H2O acts as a base, it gains one H, which forms its conjugate acid, H30. ... Conjugate acid-base pairs: H2SO4/HSO4 andH3O+/H2O ... CO32-(aq) + H2O(1) 2 HCO3 (aq) + OH(aq).

The conjugate acid of HSO4- in the reaction is H2SO4.

The conjugate acid of a particular base is obtained by adding a proton to it.

Now we have the reaction; H2SO4 (aq) + H2O(l) ----->  H3O+(aq) + HSO4^-(aq). We have to look at the reaction carefully and find out which specie can be obtained from HSO4- by adding a proton.

Clearly, the specie that we are looking for is the same specie from which a proton was removed to yield HSO4-.

Through examination of the reaction shows that this specie must be H2SO4.

3 MgCl2 + 2 Al = 3 Mg + 2 AlCl3

Since we know that we have 12 moles of MgCl2 and enough Al, we don't need to figure out the exact amount of Al.

3 MgCl2 / 2 AlCl3  =  12 mol MgCl2 / x mol AlCl2

cross-multiply

3 MgCl2(x mol AlCl2)  =  12 mol MgCl2(2 AlCl3)

3x = 24

x=8

8 moles AlCl3

Alternatively, we know that we have 12 moles of MgCl2, and a coefficient of 3. This indicates a multiplier of 4 for the entire equation, meaning 2 AlCl3 multiplied by (4) = 8 moles

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 8 moles of aluminum chloride are produced.

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.

The balanced equation is given as

3 MgCl[tex]_2[/tex] + 2 Al [tex]\rightarrow[/tex]3 Mg + 2 AlCl[tex]_3[/tex]

now we will find the mole ratio between MgCl[tex]_2[/tex] and AlCl[tex]_3[/tex].

3 MgCl[tex]_2[/tex] / 2AlCl[tex]_3[/tex]  =  12 mol MgCl2 / x mol AlCl[tex]_3[/tex]

on cross-multiplying, we get

3 MgCl[tex]_2[/tex](x mol AlCl2)  =  12 mol MgCl(2AlCl[tex]_3[/tex])

3x = 24

x=8

8 moles AlCl[tex]_3[/tex] are produced 12 moles of magnesium chloride react with enough aluminum.

Therefore, 8 moles of aluminum chloride are produced.

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.

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:

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.

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.
