6 0

humidity can be measured by the simplest hygrometer, called a sling psychrometer. It is composed of two thermometers placed together with a handle set to a chain. One of the thermometers is just like any other thermometer. Erstwhile the other one has a cloth wick wrapped over its bulb and is called a wet-bulb thermometer.

From the scattering experiments, Rutherford concluded that the positive charge was concentrated in the nucleus of the atom.

This contradicted the plum pudding model, which assumed that the positive charge was uniformly distributed throughout the atom.

A scientist measures the standard enthalpy change for the following reaction to be 81.1 kJ :2CO2(g) + 5 H2(g)C2H2(g) + 4 H2O(g)B

posledela

Answer: The enthalpy of the formation of $CO_2(g)$ is coming out to be -410.8 kJ/mol.Z

Explanation:

Enthalpy change is defined as the difference in enthalpies of all the product and the reactants each multiplied with their respective number of moles. It is represented as $\Delta H^o$

The equation used to calculate enthalpy change is of a reaction is:

$\Delta H^o_{rxn}=\sum [n\times \Delta H^o_f(product)]-\sum [n\times \Delta H^o_f(reactant)]$

For the given chemical reaction:

$2CO_2(g)+5H_2(g)\rightarrow C_2H_2(g)+4H_2O(g)$

The equation for the enthalpy change of the above reaction is:

$\Delta H^o_{rxn}=[(1\times \Delta H^o_f_{(C_2H_2(g))})+(4\times \Delta H^o_f_{(H_2O(g))})]-[(2\times \Delta H^o_f_{(CO_2(g))})+(5\times \Delta H^o_f_{(H_2(g))})]$
