Solution:- Hypochlorite ion 
has one Cl and one O atom. Cl has 7 valence electrons and O has 6 valence electrons. Since there is one negative charge on the ion,
total valence electrons = 7 + 6 +1 = 14
(note:- if there is negative charge then it is added and if there is positive charge then it is subtracted while calculating the valence electrons)
Both Cl and O atoms wants to complete their octet and so for this we put a single bond between them. Single bond means two electrons, so the remaining electrons would be 14 - 2 = 12
It means 12 electrons will be placed as lone pair of electrons. To complete the octet, we put 6 dots around each of the atom. Oxygen is more electron negative than Cl, so we show the -1 charge for oxygen.
Answer: A curve showing the relationship between temperature and time for a given amount of liquid heated at constant rate is a heating curve.
This is the option a. heating.
The increase of temperatue as result of heating may be ploted to show the changes. This increase of temperature related with the heat depends of the heat capacity of the substance. For a fixed amount of heat, substances with high heat capacity exhibit a lower increase in temperature than substances with low heat capacity.
Answer:
The concentration of CH₃OH in equilibrium is [CH₃OH] = <em>2,8x10⁻¹ M</em>
Explanation:
For the equilibrium:
CO (g) + 2H₂(g) ⇄ CH₃OH(g) keq= 14,5
Thus:
14,5 = ![\frac{[CH_{3}OH]}{[CO][H_{2}]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BCH_%7B3%7DOH%5D%7D%7B%5BCO%5D%5BH_%7B2%7D%5D%5E2%7D)
In equilibrium, as [CO] is 0,15M and [H₂] is 0,36M:
14,5 = ![\frac{[CH_{3}OH]}{[0,15][0,36]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BCH_%7B3%7DOH%5D%7D%7B%5B0%2C15%5D%5B0%2C36%5D%5E2%7D)
Solving, the concentration of CH₃OH in equilibrium is:
<em>[CH₃OH] = 0,28M ≡ 2,8x10⁻¹ M</em>
