A precipitate forms when mixing solutions of sodium fluoride (NaF) and lead II nitrate (Pb(NO3)2). Complete and balance the net
Leya [2.2K]

Answer:

See explanation

Explanation:

The molecular equation shows all the compounds involved in the reaction.

The molecular equation is as follows;

2NaF(aq) + Pb(NO3)2(aq) -------> PbF2(s) + 2NaNO3(aq)

The complete ionic equation shows all the ions involved in the reaction

The complete ionic equation;

2Na^+(aq) + 2F^-(aq) + Pb^2+(aq) + 2NO3^-(aq) -------->PbF(s) + 2Na^+(aq) +2NO3^-(aq)

The net Ionic equation shows the ions that actually participated in the reaction

The net ionic equation is;

2F^-(aq) + Pb^2+(aq)--------> PbF(s)

tatuchka [14]
<h3>Answer:</h3><h2>Covalent Bonds</h2>

<em><u>Carbon Forms Covalent Bonds</u></em>

<em><u>Carbon Forms Covalent BondsThe most common type of bond formed by carbon is a covalent bond. In most cases, carbon shares electrons with other atoms (usual valence of 4). This is because carbon typically bonds with elements which have a similar electronegativity.Jul 28, 2019</u></em>

A sample of a compound containing only carbon and oxygen decomposes and produces 24.50g of carbon and 32.59g of oxygen. what is
Fynjy0 [20]
<span>Carbon Monoxide. First, determine the relative number of moles of each element by looking up the atomic weights of carbon and oxygen Atomic weight carbon = 12.0107 Atomic weight oxygen = 15.999 Moles of Carbon = 24.50 g / 12.0107 g/mol = 2.039847802 mol Moles of Oxygen = 32.59 g / 15.999 g/mol = 2.037002313 mol Given that the number of moles of both carbon and oxygen are nearly identical, it wouldn't be unreasonable to think that the empirical formula for the compound is CO which also happens to be the formula for Carbon Monoxide.</span>
