It’s diagram because hydrogen has one proton and you’re not talking about ions so it needs another electron to stable itself
The equation to be used to
calculate the heat required to vaporize 1 gram of water at 100 degrees eclsius
and 1 atmosphere is the enthalpy. It is represented as H =
mCpT
where H is the heat released after phase change, m is
the mass of the substance, Cp is the specific heat capacity of the substance
and T
is the change in temperature.
H = mCpT
H = (1g/1000g/kg)(4.184kJ/kg-K)(100
- 20)
H = 0.335 kJ
AgCl⇒ the precipitate
<h3>Further explanation</h3>
Given
Reaction
2AgNO₃+CaCl₂⇒2AgCl+Ca(NO₃)₂
Required
The precipitate
Solution
Solubility rules :
<em>soluble compound : </em>
All compounds of NO₃⁻ and C₂H₃O₂⁻
Compounds of Cl−, Br−, I− except Ag⁺, Hg₂²⁺, Pb²⁺
So AgCl⇒ the precipitate
Ca(NO₃)₂⇒aqueous
