Answer:
Plasma.
Explanation:
In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;
I. Solid.
II. Liquid.
III. Gas
Plasma can be defined as a state of matter in which the electrons temporarily separate from the protons and as a result, it is generally referred to as the fourth (4th) state of matter due to its superheated nature.

Answer:
H2SO3(aq) + KOH(aq) ---> 2H2O(l) + K2SO3(aq)
Explanation:
Answer:
Mesosphere
Stratosphere
Thermosphere
Troposphere
Exosphere
Explanation:
The exosphere refers to the farthest region of the atmosphere that gradually fades into space.
The troposphere is the lowest layer of atmosphere. It is the layer where weather changes occur.
The thermosphere is right above the mesosphere but just below the exosphere. It is the layer where photoionization/photodissociation of molecules occurs thereby creating ions. This largely owes to interaction of molecules in this layer with ultraviolet radiation.
The stratosphere is composed of gases. Prominent among them is ozone which serves as a blanket against the sun's ionizing radiation.
The mesosphere lies above the stratosphere but just below the thermosphere. Temperature decreases steadily with height in the mesosphere.
Answer:
2.24 g
Explanation:
First we use the<em> PV=nRT</em> formula to <u>calculate the number of moles of the gas</u>:
- 0.957 atm * 1.30 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 298 K
Then we can use the<em> given molar mass</em> to <u>calculate the mass</u>:
- Molar Mass = Mass / number of moles
- 44.01 g/mol = Mass / 0.0509 mol
