A metal is one which ionizes easily and gives electrons whencompared to other elements. So it should have a lower ionization energy. Hence we would expect element 2 to be a metal.

Compare the charges and masses of protons, neutrons, and electrons.

Eva8 [605]

Answer:

Explanation:

Protons have a positive charge, with a mass of 1 amu.

Neutrons have no charge, also with a mass of 1 amu.

Electrons have a negative charge, with a mass of 1 amu.

This is why when you're calculating the mass of an element or isotope, we only count the number of protons and neutrons.

Consider the following reaction between mercury(II) chloride and oxalate ion.

Alina [70]

Answer: The rate law of the reaction is $\text{Rate}=k[HgCl_2][C_2O_4^{2-}]^2$

Explanation:

Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

For the given chemical equation:

$2 HgCl_2(aq.)+C_2O_4^{2-}(aq.)\rightarrow 2Cl^-(aq.)+2CO_2(g)+Hg_2Cl_2(s)$
