Answer:

160.18 grams

Explanation:

You find the molar mass which is 68.16 g/mol and multiply that by the number of moles present.

Answer:

$\Delta H_{rxn}=-847.6\ KJ/mol.$

Explanation:

The balanced chemical equation is:

$2Al(s)+Fe_2O_3(s)-->Al_2O_3+2Fe(s)$

Now, standard values of $\Delta H_f\ of\ all\ participants\ of\ reaction.$

$\Delta H_f(Al_2O_3)=-1669.8\ KJ/mol\\\Delta H_f(Fe_2O_3)=-822.2\ KJ/mol\\\Delta H_f(Al(s))=0\ KJ/mol\\\Delta H_f(Fe(s))=0\ KJ/mol\\$

Now, We know $\Delta H_{rxn}=\Delta H_{products}-\Delta H_{reactants}$

Putting all values of $\Delta H_f$ to above equation.

We get,

$\Delta H_{rxn}=-847.6\ KJ/mol.$

Hence, this is the required solution.

The first periodic table was organized according to atomic mass, but the current periodic table is arranged according to atomic

MrMuchimi

Answer: Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. Atomic number is usually the number of protons present in an element's nucleus. It is the average weight of an element. It is the total number of nucleons in the atom's nucleus.

Assuming there were errors in atomic masses, Mendeleev placed certain elements not in order of increasing atomic mass so that they could fit into the proper groups (similar elements have similar properties) of his periodic table.
