Answer:

International system. The SI unit for specific heat is joule per kelvin per kilogram (J/K/kg, J/(kg K), J K−1 kg−1, etc.). Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same as joule per degree Celsius per kilogram (J/°C/kg).

Anvisha [2.4K]

Answer:

$-3272$ kJ/mol

Explanation:

Given and known facts

Mass of Benzene $= 0.187$ grams

Mass of water $= 250$ grams

Standard heat capacity of water $= 4.18$ J/g∙°C

Change in temperature ΔT $= 7.48$ °C

Heat

$=250 * 4.18 * 7.48\\=7816.6 \\=7.82$

Heat released by benzine is - 7.82 kJ

Now, we know that

$0.187$ grams of benzene release $= -7.82$ kJ heat

So, $1$ g benzine releases

$\frac{ -7.82 }{0.187}\\= -41.8$

kJ/g

$0.187 * \frac{1}{78.108}=0.00239$ mol C6H6

Heat released

$= \frac{-7.82}{ 0.00239}$

$=-3272$ kJ/mol

timama [110]

To be able to calculate the number of moles for this problem, for simplicity, we assume that it is an ideal gas. We use the equation PV = nRT. We do as follows:

PV = nRT
n = PV / RT
n = 1(100000) / 0.08206 (27 + 273.15)
n = 4060.04 mol

What is one way to separate a mixture?

Dmitry_Shevchenko [17]

1. Substances in a mixture can be separated using different methods, for example distillation (separation of two liquids).
2. Mass is the amount of matter an object contains.
Volume is the amount of space occupied by a three-dimensional object.
3. d(wallet) = 15g÷5cm³ = 3g/cm³.
4. Weight of an astronaut also increases. W=m·g.
