Write the net ionic equation for the reaction that occurs when equal volumes of 0.080 M aqueous acetic acid and sodium nitrite are mixed. It is not necessary to include states such as (aq) or (s).

CH₃COO⁻ + NaNO₂ → CH₃COONa + NO₂⁻      

Explanation:

When equal volumes of 0.080 M aqueous acetic acid and sodium nitrite are mixed (1:1), we have:                            

Acetic acid = CH₃COOH    

Sodium nitrite = NaNO₂

The molecular equation is:              

CH₃COOH(aq) + NaNO₂(s) → CH₃COONa(s) + HNO₂(aq)      

The ionic equation is:

CH₃COO⁻H⁺ + Na⁺NO₂⁻  → CH₃COO⁻Na⁺ + H⁺NO₂⁻            

The net ionic equation is:          

CH₃COO⁻ + NaNO₂ → CH₃COONa + NO₂⁻      

I hope it helps you!                                  

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

elements make up everything, and they combine to make compounds.

the answer is c
