He is using filtration technique

It's a technique which is used for separation of solids and fluids by putting them through a medium which allow only fluid to pass through, leaving the solids (in this case the soil) alone.

The fluid that passed is called the filtrate

102 grams.
Equation:
Quantify of heat = mass x specific heat x difference in temperature
We have: quantity of heat : 2300J
specific heat: .449 J/g
difference in t: 80 - 30 = 50
Solve for mass: 2300 = mass x 0.449 x 50
mass = 102.449
2 sig-figs --> 102 grams

What is the ph of a 0.10 m solution of ethylamine at 25 oc? the pkb of ethylamine at 25 ºc is 3.25. ethylamine is a weak base?
denis-greek [22]
To determine the pH of a weak base, we use the equation:

pH = 14 + 0.5 log Kb

Therefore, 


pH = 14 + 0.5 log 3.25
pH = 14.26

A weak base is a base which does not fully dissociates into ions when in solution. The solution would contain cations, anions and the compound itself. Hope this helps.
