Scientists used the calculated density to determine that Mercury holds a large metallic core. Radar images taken from Earth revealed that the core is molten liquid, rather than solid. Mercury's core has more iron than any other planet in the solar system.

The true statements are B, C, and D
-first ( A ) the concentrations of reactants and products are equal is false, As the concentrations of reactants and products may be different from each other.
- But (B) the concentrations of reactants and product remains constant is true, as the equilibrium remains when there is no change in the concentration of the reactants and products.
-(c) reactants are being converted to products (and vise verse) is true also, as there are reactions still happened at a constant rate so it looks like nothing is happening.

How do you convert Pa*mm^2 to Pa*m^2?
Elden [556K]

Answer:

1 Pa\times mm^{2} =10^{-6}Pa\times m^{2}

Explanation:

Pascal(Pa) : It is the SI unit of pressure.It is equal to 1 Newton per meter square(Pa =N/m^{2})

Pa\times mm^{2} is the Unit of Force(Newton=N)

<u>Calculation,</u>

It is required to convert mm^{2} to m^{2} only, Pa is same in both so no need to alter Pa.

1 m = 1000 mm (see the image)

And,

1 mm = 0.001 m

1 mm^{2} = 0.001\times 0.001 m^{2} (Squaring both side)

1 mm^{2} = 0.000001 m^{2}

1 mm^{2} = 10^{-6}m^{2}

So,

1 Pa\times mm^{2} =10^{-6}Pa\times m^{2}
