In the reaction AI+3O2->2AI2O3 what coefficient should be placed in front of the AI to balance the reaction 1,2,3,4

Chemistry
1 answer:
patriot [66]3 years ago

Answer:

To balance the reaction, we should put a 4 in front of Al

Explanation:

<u>Step 1:</u> Data given

AI+3O2->2AI2O3

<u>Step 2:</u> Balance the equation

On the right side we have 2*3 = 6 oxygen atoms

On the left side we have 3*2 = 6 oxygen atoms as well, so those are on both side balanced

On the right side we have 2*2 = 4 Al atoms

On the left side we have only 1 Al atom

We should multiply this by 4 (place a 4 in front of the Al)

4AI + 3O2 → 2AI2O3

Now al atoms are balanced on both sides.

Hich statement describes the process of fusion, but not the process of fission?
lesantik [10]

The answer is A. this process is only in the research phase

The process of fusion involves merging of atomic nuclei to form heavier nuclei resulting in the release of enormous amounts of energy. Fusion takes place when two low mass isotopes, typically isotopes of hydrogen, unite under conditions of extreme pressure and temperature. Scientists continue to work on controlling nuclear fusion in an effort to make a fusion reactor to produce electricity. However, progress is slow due to challenges with understanding how to control the reaction in a contained space.

One of the earliest atomic models was suggested by John Dalton in the early 1800s.
Nonamiya [84]

Answer:

D. Atoms are like solid balls

Explanation:

John Dalton proposed that all matter is composed of very small things which he called atoms. This was not a completely new concept as the ancient Greeks (notably Democritus) had proposed that all matter is composed of small, indivisible (cannot be divided) objects. When Dalton proposed his model electrons and the nucleus were unknown.

Determine the electron-group arrangement, molecular shape, and ideal bond angle(s) for each of the following:
Bad White [126]

The electron group arrangement of NO²⁻is trigonal planar. The molecular shape is bent, and the bond angle is 120°.

<h3>What is the molecular shape of a compound?</h3>

The molecular geometry of the compound shows the position of nuclei and the electron of the compound. It shows how the joining of electrons and nuclei makes the shape of the compound.

Like here, the shape of nitrite is bent with lone pair which is shown by Lewis's structure The bond angle will be the distance between the nuclei of the neighbor atoms.

Thus, the electron geometry arrangement of nitrite is trigonal planer with a bent shape and the bond angle will be 120°.
