Answer:

Explanation:

N₂ (g ) + 4H⁺( aq ) + 4e⁻ = N₂H₄ ( aq )

H⁺ ion comes from acidic medium . 4 positive charge on proton is balanced by 4 electron to make left hand side neutral because right hand side is neutral .

Which compound most likely contains polar covalent bonds?
marin [14]
I would say water; water is extremely polar, and this is why it can break one of the strongest bonds, ionic bonds. NaCl, as you probably know, is a salt, and dissolves in water. However, the ionic bond holding the Na+ and the Cl- is extremely strong; the boiling point of NaCl is at 1413 degrees celcius (water is at 100 degrees celcius). This means that it requires A LOT of energy to break the bond, but water is able to dissolve and break the bond very easily. It is very polar, so I would answer your question with water. And the bond connecting the H and the O is a covalent bond.

Is the following a redox reaction? Explain.<br> NH₃(aq) + HCl(aq) → NH₄Cl(aq)
jeyben [28]

The process is not a redox reaction.

The reaction between ammonia (NH_{3} )and hydrochloric acid (HCl) to produce ammonium chloride (NH_{4} Cl) has modified the oxidation number of no atom in the reactants. As a base, ammonia interacts easily with hydrochloric acid to produce ammonium chloride salt. A neutralization reaction between an acid and a base is what the described process is, and it is NOT a redox reaction.

A reaction is referred to as a redox reaction if two or more reactants belonging to a single reaction exchange one or more electrons, i.e., one reactant releases one or more additional electrons while the other obtains one or additional electrons. The reacted substance that releases electrons is oxidized and becomes a reducing substance. A reduced oxidizing agent is the reactant that accepts electrons.

How many moles are in 15.5-g SiO2
DochEvi [55]

Answer:

0.26 moles

Explanation:

Number of moles = mass/molar mass

Mass of SiO2 = 15.5g

Molar mass of SiO2 = 60.08g/mol

Number of moles = 15.5g/60.08g/mol

=0.257

= 0.26 moles
