How many grams of pure aluminum could be produced from 999 g of aluminum oxide?

Answers

Answer:

Explanation:

First, calculate the molar mass of Aluminum Oxide (Al2O3), by multiplying the number of the constituent atoms, by their relative atomic abundances . Inserting the atomic masses into the equation gives you  . Then find the percent of Aluminum by mass, in Aluminum Oxide.  Finally, set up an equality, where 53.02% of the mass of Aluminum Oxide, is 999 grams of Aluminum

Answers

The Elephant Maximus is the species that was introduced and later became extinct on Maguindanao.

Extinction occurs as all members of a species die, and therefore the species disappears. This includes complete extinction or extinction of the species in a specific zone.

In the case of the Elephant Maximus, which is known as the Asian Elephant, this species became extinct in a region known as Maguindanao in the Philippines.

This partial extinction occurred as the elephants from this zone were taken to Sabah in Malaysia from the 13th century to the 16th century. This occurred because the Sultans of this region considered this elephant to be a valuable and even sacred animal.

does ch3 have resonance structure?​

Answers

Answer:

yes

Explanation:

if u watch or look closely u will observe it

The CH₃ has resonance structures as it has odd number of hydrogen atoms.

In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures ,also variously known as resonance structures or canonical structures into a resonance hybrid (or hybrid structure) in valence bond theory. It has particular value for analyzing delocalized electrons where the bonding cannot be expressed by one single Lewis structure.

Thus,  CH₃ has resonance structures as it has odd number of hydrogen atoms.

d. ZnS

Answers

The order of increasing ionic property is;

WO3 < ZrS2 < MnS2< ZnS < MnS

Ionic compounds are compounds that contain an ion pair. Typically, ionic compounds are formed between metals and nonmetals.

The degree of ionic character depends on the type of metal involved and the magnitude of charge it carries.

Typically, first row transition metals form ionic compounds. The degree of ionic character depends on the row in which the metal is found and the magnitude of charge it carries.

Hence, the order of ionic character of the compounds from most ionic to least Ionic is; WO3 < ZrS2 < MnS2< ZnS < MnS.

Why do both nuclear and chemical
changes occur?

Answers

Answer:

The change in energy for a chemical reaction has to do with the potential energy of the electrons. The change in energy for a nuclear reaction has to do with the potential energy of the nucleus. The change in energy for a nuclear change is many orders of magnitude larger than for a chemical change.

The statement that describes both nuclear and chemical changes occur is "potential energy."

What is nuclear and chemical reaction?

Nuclear reactions include a change in the nucleus of an atom, which usually results in the production of a different element. Chemical reactions, on the other hand, require just electron rearrangement and no changes in nuclei.

A nuclear reaction is any reaction that causes the nucleus of an atom to change. An atom's nucleus is made up of protons and neutrons. It seems to reason that a nuclear reaction alters the amount of protons and/or neutrons in an atom.

Chemical changes occur when bonds between molecules or atoms are broken and/or formed to form a new material. In this case, the new substances' qualities differ from the old, the particles differ, and the number of particles can alter.

The change in energy for a nuclear change is many orders of magnitude greater than the change in energy for a chemical change.
