Q=mcΔT
q=(125g)(0.446 J/(g x °C))(78°C - 23.5°C)
q=(125 g)(0.446 J/(g x °C))(54.5°C) (Be sure to cancel all similar units)
q= 3038.375 J
<span>68g since 34/100 is 34 right?
so if you have 200g of H2O you can put in twice as much KCl
so it is 68g</span>
Yes, that is all correct!
The atomic number is the same as the number of protons (12).
Magnesium = Mg
Atomic mass is 24. 305.
<span>That the glassware contains no residual chemicals that will alter the results of an experiment.</span>
I love these type of questions :)
