Answer: The molality of solution is 0.66 mole/kg
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

where,
n = moles of solute
= weight of solvent in g
moles of
= 
Now put all the given values in the formula of molality, we get

Therefore, the molality of solution is 0.66 mole/kg
Answer:k
Explanation:
Atomic theory would be the theory or explanation of the function of atoms and their relationship with each other.
D.) Balanced equation is Zn + 2HBr - - - > ZnBr2 + H2.
<span>The only scenario that
will allow you to reach an equilibrium mixture involving these chemicals is to
place NH3 into a sealed vessel. This reaction requires pressures between 2100,
3600 psi, and temperatures between 300 and 550 degree Celsius. With this given
temperature and pressure, the ammonia naturally decomposes into nitrogen and
hydrogen gas at the same rate. When this happen, the concentrations of these
chemicals become constant and the system is said to be at equilibrium.</span>
