The specific heat capacity of water is 4.1813 J/(g*K). So we have 3 values with the units kJ, g and J/(g*K). We can trivially convert from kJ to J by multiplying by 1000. And we want to get a result with the unit K (degrees Kelvin). So let's do it. First, let's cancel out the g unit by multiplying.
4.1813 J/(g*K) * 485 g = 2027.9305 J/K
Now we can cancel out the J unit by dividing. But if we divide by the energy, we'll be left with the reciprocal of K, not K. So instead divide by the J/K unit. So
14500 J / 2027.9305 J/K = 7.150146418 K
Rounding to 3 significant figures gives us 7.15 K.
And since degrees C and degrees K are the same size, the temperature will increase by 7.15 degrees C</span>
Answer:
1) 4Fe + 3O2 → 2Fe2O3
2) H2 + Cl2 → 2HCl
3) 2Ag + H2S → Ag2S + H2
4) CH4 + 2O2 → CO2 + 2H2O
5) 2HgO → 2Hg + O2
6) 2Co + 3H2O → Co2O3 + 3H2
Isotonic refers to a solution having the same water potential as compared to another solutions such that there is no net movement of water molecules across a membrane when these two solutions are put together
It's False.
Only metals can be conductors of heat and electricity.
