Explanation:
First, get both values into the same units
To covert from Kelvin to degrees C, subtract 273.15
1210 - 273.15 =936.85
Melting point of germanium=936.85 degrees C
Melting point of gold= 1064 degrees C
Therefore germanium would melt first because it has the lower melting point.
The answer I’m sure it’s c
For an exothermic reaction,heat energy is released out.
Enthalpy change = Energy of products - Energy of reactants
Here enthalpy change is negative,as energy of products is less than energy of reactants.
Hence heat is released in exothermic reactions.
And the products have lower potential energy than the reactants, and the enthalpy change is negative.
Ammonium Oxalate (NH4) 2c204 is the formula number and has a mass of 124.0959
To turn the flow of electricity on or off. Probably wrong
