sample of liquid water at 100 degrees C absorbs 113 kJ of heat. HOw much water will be converted to steam heat vaporization if water is 2.26 kJ/g I just need help with what formula to set this up

A 0.170 kg hockey puck is initially moving at 21.2 m/s [W] along the ice. The coefficient of kinetic friction for the puck and the ice is 0.005. (a) What is the speed of the puck after traveling 58.5 m? my solution: Fnet=Fk ma=μk.Fn ma=μk.mg a=(0.05)(0.17...

what are the products of Ca +H +OH-->?

Does Pb(NO3)2 + Cu has a reaction? if so, what will it be?

Can someone explain to me, what does Metastable isotope means? I already read the definitions on the internet but I really don't understand it. Thanks in advance.

calculate the mass of impure KOH needed to make up 1.20 L of 0.60 mol/L KOH(aq)? Assume the impure KOH is 84% KOH by mass and 16% water.

Thank you

will it be Ca + H2O?

Thank you

How about TC-99m? it is a metastable isotope, but the half life is 6hours. it is said that metastable isotope has lived longer than isotopes in a stable stae I don't get that part.

0.2 miles

I did the math part - E= -2.42

Oreo is correct except 1 is fertile land and rivers. thanks bunches! (These were correct for the practice as of August 2017) Ps cheating gets you nowhere!
