Answer:
Covalent compounds have low forces of attraction between their molecules (i.e. one H2O molecule isn't as attracted to another H2O molecule than the oppositely charges ions are in an ionic compound). Little energy is needed to break their bonds, therefore they have low meting points. Hope this is what you are looking for!

Answer:
Every chemical equation follows to the law of conservation of mass, which states that matter cannot be created or destroyed. When you have an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced therefore it is following the law of conservation of mass.

Answer: 
for this reaction at this temperature is 0.029
Explanation:
Moles of 
= 2.00 mole
Volume of solution = 4.00 L
Initial concentration of 
The given balanced equilibrium reaction is,
Initial conc. 0.500 M 0 M 0 M
At eqm. conc. (0.500-2x) M (x) M (x) M
The expression for equilibrium constant for this reaction will be,
![K_c=\frac{[H_2\times [Br_2]}{[HBr]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BH_2%5Ctimes%20%5BBr_2%5D%7D%7B%5BHBr%5D%5E2%7D)
Equilibrium concentration of ![[Br_2]](https://tex.z-dn.net/?f=%5BBr_2%5D)
= x = 0.0955 M
Now put all the given values in this expression, we get :
Thus for this reaction at this temperature is 0.029
