Answer:
is a way of presenting information about the chemical proportions of atoms
Explanation:
Almost always, the first way in which biology researchers present the results of their latest research is to discuss the results of previous research that they want to build off of.
The ground could sink and sink holes could occur, otherwise the parking lot could simply break apart and wear faster
Answer:
The specific heat of the alloy 
Explanation:
Mass of an alloy
= 25 gm
Initial temperature
= 100°c = 373 K
Mass of water
= 90 gm
Initial temperature of water
= 25.32 °c = 298.32 K
Final temperature
= 27.18 °c = 300.18 K
From energy balance equation
Heat lost by alloy = Heat gain by water
[

)
25 ×
× ( 373 - 300.18 ) = 90 × 4.2 (300.18 - 298.32)

This is the specific heat of the alloy.
Answer:
The solubility product of zinc sulfide is
.
Explanation:
Solubility of the zinc sulfide = 

S S
The expression of solubility product is given by :
![K_{sp}=[Zn^{2+}]\times [S^{2-}]](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BZn%5E%7B2%2B%7D%5D%5Ctimes%20%5BS%5E%7B2-%7D%5D)


The solubility product of zinc sulfide is
.
