Feb 11, 2016 · When decaying by alpha emission a nucleus drops by 4 in mass number and 2 in atomic number and emits a helium nucleus (alpha particle) which has mass number 4 and …

Some very hot rocks have a temperature of #190 ^o C# and a specific heat of #90 J/ (Kg*K)#. The rocks are bathed in #270 L# of boiling water. If the heat of the rocks completely vaporizes the …

Oct 14, 2017 · t^ (38/7) t^ (15/5)*t^ (11/7) =>t^ (15/5+11/7) =>t^ (135/35+55/35) =>t^ (190/35) =>t^ (38/7)

"3.2 mol kg"^(-1) In order to be able to calculate the molality of the solution, you need to know the number of moles of solute present for every "1 kg" = 10^3 "g" of solvent. In your case, you …

Approx. 190*g... By definition, rho, is given by the quotient.... rho_"density"="mass"/"volume", and thus has units of g*mL^-1-=g*cm^-3... And so we simply rearrange ...

Dec 6, 2015 · Here the minus sign is used because heat lost carries a negative sign.

You have 150 grams of water at 25C and 40 grams of water at 50C. You mix them together in a calorimeter to find the final temperature of the mixture. Using your incredible math skills, …

x=+-sqrt(a-v) v=sqrt(a^2)-x^2 Apply square root rule sqrt(b^2)=b. v=a-x^2 Add x^2 to both sides. v+x^2=a Subtract v from both sides. x^2=a-v Take the square root of both sides. sqrt(x^2)=+ …
