BRAINLIESTTT ASAP! PLEASE HELP ME :)
gogolik [260]

Answer:

"Heat of combustion"

Explanation:

A physical property is characteristic of a substance that can be observed or measured without changing its chemical composition, such as color, molecular weight, and volume. A chemical property can only be observed or measured by changing the chemical composition of the substance, such as reactivity, flammability and oxidation states.

Hope this helps! :)

C2d3 has a solubility product constant of 9.14×10−9. What is the molar solubility of c2d3?
shutvik [7]

Answer : The molar solubility of C_2d_3 is 9.67\times 10^{-3}M

Explanation :

The solubility equilibrium reaction will be:

C_2d_3\rightleftharpoons 2C^{3+}+3d^{2-}

The expression for solubility constant for this reaction will be,

Let the molar solubility be, 'x'

K_{sp}=(2x)^2\times (3x)^3

Now put all the given values in this expression, we get:

9.14\times 10^{-9}=108x^5

x=9.67\times 10^{-3}M

Therefore, the molar solubility of C_2d_3 is 9.67\times 10^{-3}M
