Answer:

Explanation:

The equation is not correctly written, so let's start with that.

4Al + 3O2 ====> 2Al2O3?

Totally correct, including the balance numbers, would be

4moles aluminum + 3 moles Oxygen ===> 2 moles of Aluminum Oxide

Anything else is incomplete.

20 ML of a gas at 200 K is heated until the new volume is 55ML what is the final temperature of the gas
MrRa [10]

Answer:

T2 = 550K

Explanation:

From Charles law;

V1/T1 = V2/T2

Where;

V1 is initial volume

V2 is final volume

T1 is initial temperature

T2 is final temperature

We are given;

V1 = 20 mL

V2 = 55 mL

T1 = 200 K

Thus from V1/T1 = V2/T2, making T2 the subject;

T2 = (V2 × T1)/V1

T2 = (55 × 200)/20

T2 = 550K

An atom of 14 6 c carbon decays by gamma decay which atom is left after the decay
ladessa [460]
Answer is: carbon.

<span>During gamma emission the nucleus emits radiation without changing its composition, if for example have nucleus with six protons and six neutrons (carbon atom) and after gamma decay there is nucleus with six protons and six neutrons.
Gamma rays are the electromagnetic waves with the shortest wavelengths (1 pm), highest frequencies (300 EHz) and highest energy (1,24 MeV).</span>

If a 0.320 mM solution of MnO41- has an absorbance of 0.480 at 525 nm in a 1.000 cm cell. What is the concentration of a MnO41-
larisa [96]

Answer:

Hence the concentration of a MnO41- solution that has absorbance of 0.490 in the same cell at that wavelength is 0.3266.

Explanation:

Now A = el, el=const

Then,

A2 / A1 = C2/ C1\\\\0.49/ 0.48 = C2 / 0.32\\\\C2 = 0.3266

According to molecular orbital theory, the regions of the wave function with the highest probability of finding electrons are ar
Vlada [557]

According to molecular orbital theory,  regions of  wave function with highest probability of finding electrons are areas with constructive interference.

An electron is a negatively charged subatomic particle that can exist either free or bound to an atom (not bound). A bound electron is one of the three primary types of particles that make up an atom, along with protons and neutrons. Protons, neutrons, and electrons combined make up the atom's nucleus. A proton's positive charge balances an electron's negative charge. When an atom has an equal number of protons and electrons, it is said to be in a neutral state. Electrons are distinct from other particles in a number of ways. They have a much lower mass, are found outside the nucleus, and exhibit both wave- and particle-like characteristics. The electron is a basic particle.
