Answer:
11 yes
12 H2O( water molecules)
13 3H2O( water molecules)
Explanation:
Sry, my phone's a potato, so I didn't read it properly, so I'm not sure about the question 11.
11-yes, they stay together, but they release 3 molecules of OH an H.
12- here it talks about what will happen with OH and H: they will be H2O (water molecules).
13- and here we end it with the informations that we got: 3 fatty acids+ glycerol---> fat+ 3H2O( the 3 H and 3 OH)
C
This is because 10+5=15
15/45=0.3
Typically the warm front is pushed upward and the cold pushed downward.
This is a common laboratory experiment called calorimetry which determines the specific heat capacity of the sample metal.
By the Conservation of Energy,
Energy of Metal = Energy of Water
mCmetalΔT = mCwaterΔT, wherein Cwater = 4.187 J/g·°C
(26.5 g)(Cmetal)(98 - 32.5°C) = (150 g)(4.187 J/g·°C)(32.5 - 20°C)
Solving for Cmetal,
<em>Cmetal = 4.523 J/g·°C</em>
