What is the reason behind that the melting and boiling point of iron is more than that of sodium?

sweet [91]

Answer:

As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. This means that the melting point and boiling point of metals are more similar to those for ionic compounds than for covalent substances.

2C2H2(g) 5O2(g) → 4CO2(g) 2H2O(g) This is a balanced equation for the combustion of acetylene(C2H2). How many moles of oxygen(O2

omeli [17]

The moles of oxygen required to completely react with 1-mole acetylene is 2.5 mol.

The moles of reactant and product in a chemical reaction to the whole number ratio is given by the stoichiometric coefficient of the balanced chemical equation.

<h3>Computation for the moles of oxygen</h3>

The balanced chemical equation for the reaction is :

$\rm 2\;C_2H_2\;+\;5\;O_2\;\to\;4\;CO_2\;+\;2\;H_2O$

From the balanced chemical equation, the 2 moles of acetylene react with 5 moles of oxygen.

The moles of oxygen react with 1 mole of acetylene are:

$\rm 2\;mol\;C_H_2=5\;mol\;O_2\\\\1\;mol\;C_2H_2=\dfrac{5}{2}\;\times\;1\;mol\;O_2\\\\ 1\;mol\;C_2H_2=2.5\;mol\;O_2$

The moles of oxygen required to completely react with 1-mole acetylene is 2.5 mol.
