Answer:

136.15 g/mol is the molar mass of calcium sulfate.

Explanation:

Molar mass is defined as a total sum of atomic masses of all and each type of atoms constituting the molecule.

Atomic mass of calcium = 40.08 g/mol

Atomic mass of sulfur = 32.07 g/mol

Atomic mass of oxygen = 16.00 g/mol

Molar mass of calcium sulfate, (CaSO_4) :

=1\times 40.08 g/mol+1\times 32.07 g/mol+4\times 16.00g/mol

=136.15 g/mol

136.15 g/mol is the molar mass of calcium sulfate.

Answer:

  1. According to the law <br> Mass of reactants = mass of product, here <br> `underset(10 g)(CaCO_(3))rarr underset(4.4 g)(CO_(2))+underset(x)(CaO)` <br> Hence, x = 10 g - 4.4 g = 5.6 g <br> Which is mass of CaO.d

Hi, can someone help me with these<br> why do hydrogen sulfide has a low boiling point
riadik2000 [5.3K]

Hydrogen sulfide has a low boiling point because it is only a slightly polar molecule, meaning that it only has weak dipole-dipole intermolecular forces. Because of its relatively weak intermolecular forces, it has a low boiling point.

andrezito [222]

Answer : The thermal energy produced during the complete combustion of one mole of cymene is -7193 kJ/mole

Explanation :

First we have to calculate the heat released by the combustion.

q=c\times \Delta T

where,

q = heat released = ?

c = specific heat of calorimeter = 3.640kJ/^oC

\Delta T = change in temperature = 19.35^oC

Now put all the given values in the above formula, we get:

q=3.640kJ/^oC\times (19.35)^oC

q=70.43kJ

Thus, the heat released by the combustion = 70.43 kJ

Now we have to calculate the molar enthalpy combustion.

\Delta H=-\frac{q}{n}

where,

\Delta H = molar enthalpy combustion = ?

q = heat released = 70.43 kJ

n = number of moles cymene = \frac{\text{Mass of cymene}}{\text{Molar mass of cymene}}=\frac{1.608g}{164.22g/mol}=0.009792mole

\Delta H=-\frac{70.43kJ}{0.009792mole}=-7193kJ/mole

Therefore, the thermal energy produced during the complete combustion of one mole of cymene is -7193 kJ/mole
