Hey im happy to help!
Heat can float from one place to another, like all energy.Heat floats in solids by conduction, that happens because the molecules hit one another.Heat within the solid will flow from hot to cold.Heat will flow downward if its cold there.
Hope this helps, have a great rest of your day!
A diversity of scientists is important for reducing bias and for providing different ways of looking at the world. ... To the extent that we can remove our biases and learn from multiple perspectives, we will understand our world better.
Water drops come in different sizes.
Let's imagine a drop weighs a quarter of a gram.
The molar mass of water is about 18g/mol, which means that 6.02 x 10^23 water molecules (AKA a mole of water molecules) weigh about 18 grams.
A quarter of a gram is 1/72 of 18, so it contains 1/72 times 6.02 x 10^23 molecules. That equals 8361111111111110000000 molecules.
In scientific notation that is... 8.36 x 10^21 molecules.
D. to preserve the union. He changed the meaning of the war when he passed the Emancipation Proclamation in 1863.
Hope this helps. Please let me know if I'm wrong :)
Answer: a) 0.0144mol/L
b) 
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as 
The equation for the ionization of the 
is given as:
We are given:
Solubility of = 
Molar Solubility of = 
1 mole of gives 1 mole of 
and 2 moles of 
ions
Solubility product of = ![[Pb^{2+}][Cl^-]^2](https://tex.z-dn.net/?f=%5BPb%5E%7B2%2B%7D%5D%5BCl%5E-%5D%5E2)
![K_{sp}=[0.0144][2\times 0.0144]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5B0.0144%5D%5B2%5Ctimes%200.0144%5D%5E2)
Thus the solubility product constant is
