You need the heat of fusion of ice to solve this problem. <span>the heat of fusion of water = 334 J/g </span><span>
the formula to solve for heat is </span>q = m·ΔH<span>f</span>
just plug the values
q= (50.0 g) (334 j/g)= 16700 joules or 16.7 Kj
The formula of a compound is ![Ni(NO_3)_2](https://tex.z-dn.net/?f=Ni%28NO_3%29_2)
Given:
The ions
and ![NO_3^-](https://tex.z-dn.net/?f=NO_3%5E-)
To find:
The formula for ions
and ![NO_3^-](https://tex.z-dn.net/?f=NO_3%5E-)
Solution:
The ion with a positive charge (cation) = nickel ion = ![Ni^{2+}](https://tex.z-dn.net/?f=Ni%5E%7B2%2B%7D)
The ion with a negative charge (anion) = nitrate ion = ![NO_3^-](https://tex.z-dn.net/?f=NO_3%5E-)
Valency on nickel ion = 2
Valency on nitrate ion = 1
Using the criss-cross method as shown in image
