RSB [31]

Answer:

Explanation:  Rutherford model, also called Rutherford atomic model, nuclear atom, or planetary model of the atom, description of the structure of atoms proposed (1911) by the New Zealand-born physicist Ernest Rutherford. The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun. Hope that helps!

Fe2O3(s) + 3CO(g) → 2Fe(s) + 3CO2
Elena L [17]

Mass of carbon monoxide : 0.95 g

<h3>Further explanation</h3>

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂

MW Fe₂O₃ : 159,69 g/mol

mol Fe₂O₃ :

\tt \dfrac{1.8}{159.69}=0.0113

mol ratio Fe₂O₃ : CO = 1 : 3, so mol CO :

\tt 3\times 0.0113=0.0339

mass CO (MW =  28,01 g/mol) :

\tt m=mol\times MW\\\\m=0.0339\times 28.01\\\\m=0.950~g

Write balanced complete ionic equation for hcl(aq)+lioh(aq)→h2o(l)+licl(aq)
olga2289 [7]
<span>H and Li have a +1 charge. Cl and OH have a -1 charge. When written out it should look like this: H(+1) + Cl(-1) + Li(+1) + OH(-1) --> H2O + Li(+1) + Cl(-1) if you wanted the net ionic equation it would be: H(+1) + OH(-1) --> H2O</span>
