Thanks that really helped. :-p

If you mix BaNO(3)2 + NaOH what would be the chemical chemical reaction in formula?

take an ice cube at 0 degrees C and place it in 500 grams of water at 60 degrees C . The final temperature is 18 degrees C . What is the mass of the ice cube? heat of fusion for water is 80 cal per g. Anyone?

Thanks! Much appreciated.

Can someone help me on finding volume of butter. the stick has 120 cm^3 and a mass of 110 g. So what is the volume of 1 g of butter. I know you have to find density of 110/120 = .92 but then I get stuck what's next. thanks

Correct gnome :) Thanks for your help all !

I don't know. I have been researching this on the Net and as close as I have come is possibly the coefficient would be 0.5 and force would be 15 =30 x .5 so force would be 15 but I am not sure. Anyway thanks for the help. Bedtime for me. :)

See that's the problem there is only a very small section on this and nothing that helped but again thanks for your suggestion.

I really don't know. Sorry. Thats why I am asking here. Thanks though for trying to help. I appreciate it.

Totally lost here but thanks for trying to help.

A man is pushing a box at a constant velocity. The weight of the box is 30 N and the force is 15 N. How do you arrive at the force of friction and the coefficient of sliding friction.
