The melting point of potassium =
Melting point of titanium =
Titanium has a stronger metallic bonding compared to potassium. Titanium being a transition metal has greater number of valence electrons (4 valence electrons) contributing to the valence electron sea compared to potassium which has only one valence electron. The atomic size of Titanium much lower than that of potassium, so the bonding between Titanium atoms is stronger than that of potassium. Hence, the melting point of Titanium is much higher than that of potassium.
The question is incomplete, complete question is :

The net reaction is:
Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants and . If you need to include any physical constants, be sure you use their standard symbols
Answer:
Equation that gives the overall equilibrium constant K in terms of the equilibrium constants :
Explanation:
Step 1 :
Expression of an equilibrium constant can be written as:
Step 2 :
Expression of an equilibrium constant can be written as:
The net reaction is:
Expression of an equilibrium constant can be written as:
Multiply and divide ;
So , the equation that gives the overall equilibrium constant K in terms of the equilibrium constants :
Freeze it in a freezer this will change it from liquid to solid
Answer:
We need 113000 J of heat (option 2 is correct)
Explanation:
Step 1: Data given
Mass of liquid water = 50.0 grams
ΔHVap = 2260 J/g
Temperature = 100 °C
ΔHVap = The amount of heat released to change phase of a liquid water to steam = 2260 J/g
Step 2: Calculate the heat needed
Q =m* ΔHVap
⇒with Q = the amount of heat needed = TO BE DETERMINED
⇒with m = the mass of water = 50.0 grams
⇒with ΔHVap = 2260 J/g
Q = 50.0 grams * 2260 J
Q = 113000 J
We need 113000 J of heat (option 2 is correct)
