Answer:

36 oxygen atoms

Explanation:

From the question given above, the following data were obtained:

Compound => 4Al₂(CO₃)₃

Number of Oxygen atom in the compound =?

The number of oxygen atom in the above compound can be obtained as follow:

4Al₂(CO₃)₃

Al = 4 × 2 = 8 atoms

C = 4 × 3 × 1 = 12 atoms

O = 4 × 3 × 3 = 36 atoms

From the simple illustration made above, there are 36 oxygen atoms in the compound.

water decomposes in an evacuated 2.00L container. If you started with 20.0 grams of water, determine the total resulting pressur
Deffense [45]

Resulting pressure is 13.6 atm.

<u>Explanation:</u>

Using Ideal gas equation, we can find the pressure of the gases formed in the reaction.

PV = nRT

Number of moles, n = given mass / molar mass = 20 g / 18 g/mol

                           = 1.11 moles

Volume, V = 2 L

Temperature, T = 25°C + 273 = 298 K

R = gas constant = 0.08206 L atm K⁻¹ mol⁻¹

P = nRT/V

 = 1.11×0.08206 ×298 / 2

 = 13.6 atm

Which is a form of kinetic energy
Evgesh-ka [11]

Answer:

there are several types of Kinetic Energy: radiant, thermal, sound, electrical and mechanical.

Explanation:

Radiant energy is energy that travels in waves Its given off by electromagnetic radiation

Thermal energy results in an object or a system having a temperature that can be measured but it has to have motion

Sound a mechanical wave and as such consists physically in oscillatory elastic compression and in oscillatory displacement of a fluid

Electrical When you let go of that ball and let it fall, the potential energy converts into kinetic energy

Mechanical is the result of its motion
