The liquid freezes at 32 degrees celcius(A) is not the properties of water as water freezes at 0 degrees celcius
Moles of NaCl
Molality
i is vant Hoff factor
For NaCl vant Hoff factor is 2( Actually 1.9)
Answer:it takes about a day
Explanation:
Answer : The correction equation will be:
Explanation :
Electron affinity : It is defined as the addition of electron to the atom or to the ion. The atom or ion is always in gaseous phase.
In other words we can say that, the gaining of electrons is said to be an electron affinity.
As, the given element is a metal given in cationic form, so its positive ion will gain an electron to form a neutral atom.
The balanced and correct equation for electron affinity of the cesium ion will be:
There is a time delay of almost two to three minutes before the reaction proceeds because of the following processes:
<span>1) </span><span> The acid starts to go yellow as the dehydration begins.</span>
<span>2) </span><span> The rate of dehydration then accelerates as the acid heats up because the reaction is exothermic/chemical (releases energy by light or heat). As the sugar molecules are stripped of water, the heat generated turns the water into steam which then expands the remaining carbon into a porous, smoking, black column.</span>
<span>3) </span>This expands out of the reaction vessel, producing a choking acrid vapor and the smell of burned sugar.
<span> At this stage, sulfuric acid is highly corrosive and will burn skin so one must avoid contact with it. </span>
