What is the difference between physical and chemical changes?
Bumek [7]
In physical changes, the chemical makeup of an atom stays the same, like water turning into ice or steam, everything is still water but a different physical form. A chemical change is where an atom’s chemical make up does change, like wood burning to become soot, which is not wood, or photosynthesis, where carbon dioxide and water turn into a carbohydrate and oxygen

Studentka2010 [4]

Answer:

Balanced equation

CS2(l) + 3O2(g)------> CO2(g) + 2SO2(g)

Explanation:

For a chemical equation to be balanced, the number of atoms of each element on the left Hans side of the reaction equation must equal the number of atoms of that element on the right hand side of the reaction equation.

Atoms of oxygen are six on both sides of the reaction equation. Atoms of sulphur are two while there is only one atom of carbon on both sides of the reaction equation.

Drag each pressure unit with the corresponding number to describe standard atmospheric pressure.
saw5 [17]

Answer:

The answer to your question is:

                                                    Psi = 14.7

                                                     Atm = 1

                                                     kPa = 101.3          

Explanation:

Psi: means "Pounds of force per Square Inch of area " an is a unit of pressure.

Atm: means atmosphere and is a unit of pressure defined as 101325 Pa.

kPa: is defined as the force of 1 Newton applied over one square meter.

      ( 101325 Pa = 101.3 kPa)

Then

        Psi = 14.7

         Atm = 1

         kPa = 101.3
