How many protons, neutrons and electrons are there in a given neutral atom?
How many protons, neutrons and electrons are there in a given neutral atom?
Fill in the missing pieces of the table. This table is Joules, cal and kJ.
The boiling point, melting point, specific heat liquid, specific heat solid, ΔHvap and ΔHfus are given. Determine how many kJ of heat (ΔH) are needed to melt or freeze x grams at it’s normal boiling point. This solver works for both questions asking for melting the sample and questions asking to freeze the sample.
The crystal structure is pictured and the edge length is given (in pm). Determine the density in g/cm3.
After a transfer of x kJ of energy to an x kg block, a final temp is given. The specific heat is also given. You need the initial temperature.
