5.167g of calcium chloride is dissolved in 101.0mL of water in a calorimeter whose calorimeter constant is 15.3J/°C. The temperature rises from 18.4°C to 27.2 ...
Answer : The molar solubility of 
is 
Explanation :
The solubility equilibrium reaction will be:
The expression for solubility constant for this reaction will be,
Let the molar solubility be, 'x'
Now put all the given values in this expression, we get:
Therefore, the molar solubility of is
19. For the reaction, 2S+ 30=2SO3, how many moles of so3 will be produced from 12.5 g 02 and excess S?
:
For the reaction: 2S(s) + 3O2 -> 2SO2(g) How many moles of SO3 will be produced from 2.0 mol O2 and excess S?
It represents an observation and he formed a hypothesis to explain the observation.
The Lewis structure of hypochlorous acid has oxygen (O) with single bonds between hydrogen and chlorine. In the Lewis structure, we see that hypochlorous acid has 14 valence electrons. Four are used as bonding electrons, and the remaining 10 are nonbonding electrons on oxygen and chlorine.
