Q=mc(delta T)
m= Q/ c(delta T)
m= 1200 J / (4.19 J/kg C) (15-10)
m= 57. 28 kg

What is the final concentration if 50.0 ml of a 2.00 m solution are diluted to 500.0 ml??
laila [671]
In order to calculate the final concentration of a dilution, it is important to memorise and remember the following equation:

C1V1/C2V2
Where: 
C1 = Initial concentration
V1 = Initial volume
C2 = Final concentration
V2 = Final volume

We are given three of the four, and we are asked to calculate the final concentration in moles, so we may substitute these given values into our equation as follows:

C1V1 = C2V2
(2.00m)(50.0 mL) = (C2)(500mL)
100 = C2(500mL)
C2 = 0.2 m

In the final step, we simply divide 100 by 500 to get our final concentration value.

What properties prompted Rutherford to use alpha particles and gold? (What set of experimental conditions would make it easiest
Ilia_Sergeevich [38]
<span>Gold is  a stable heavy metal that is easily formed into uniform and thin sheets of measurable property. Alpha particles are relatively massive (compared to electrons) and so deflection is less dramatic and more easily measured. This is the property that prompted Rutherford to use alpha particles and gold. </span>
The particles that are positively charged were fired at the gold foil and when it reached that goldatoms’ nuclei, which are also positively charged, the particles were repelled back
