Answer:
Over time the metal will cool and the water will heat up. Eventually the two objects will have the same temperature
Explanation:
Supplementary angles add up to 180, so
6x+60+90 = 180 and solve for x
6x= 30
x=5
Answer:
The answer to your question is M = 36.49 g
Explanation:
Data
mass = 8.21 g
volume = 4.8064 L
Temperature = 200°C
Pressure = 1.816 atm
M = ?
Process
1.- Convert temperature to °K
°K = 273 + 200
°K = 473
2.- Calculate the number of moles
n = (PV)/RT
n = (1.816)(4.8064)/(0.082)(473)
n = 0.225
3.- Calculate the molar mass
M --------------- 1 mol
8.21 g ---------- 0.225 moles
M = (1 x 8.21)/0.225
M = 36.49 g
Answer:C
Explanation: they break apart into ions as they dissolve into solution this process is known as dissociation.
