Net ionic equation for NaOH(aq) + NH4Br(aq) —> NaBr(aq) + NH3(g) + H2O(l)
Greeley [361]

Answer:

OH⁻(aq) + NH₄⁺(aq) →  NH₃(g) + H₂O(l)

Explanation:

The net ionic equation is a way yo write a chemical equation that list only the species that are involved in the reaction.

For the reaction:

NaOH(aq) + NH₄Br(aq) → NaBr(aq) + NH₃(g) + H₂O(l)

Ionic equation is:

Na⁺(aq) + OH⁻(aq) + NH₄⁺(aq) + Br⁻(aq) → Na⁺(aq) + Br⁻(aq) + NH₃(g) + H₂O(l)

<em>-Ions comes from the species that are in aqueous phase-</em>

And net ionic equation is:

<em>OH⁻(aq) + NH₄⁺(aq) →  NH₃(g) + H₂O(l)</em>

A bowling ball is pushed with a force of 22.0 N and accelerates at 5.5m/s. What is the mass of the bowling ball
Luden [163]
Hello!

Data:

F (force) = 22.0 N
m (mass) = ? (in Kg)
a (acceleration) = 5.5 m/s²

We apply the data to the Resultant Force formula, we have:

F =m*a

22 = m*5.5

5.5 m = 22

m =  \dfrac{22}{5.5}

\boxed{\boxed{m = 4\:Kg}}\end{array}}\qquad\checkmark

I hope this helps. =)

Nitrogen monoxide and hydrogen react to form nitrogen and water, like this: 2NO+2 H2(g)-N29)+2H2O(9) Write the pressure equilibr
lara31 [8.8K]

Answer:

Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)² = Kp

Explanation:

The reaction is:

2NO + 2H₂ → N₂ + 2H₂O

The expression for Kp (pressure equilibrium constant) would be:

Partial pressure N₂ . (Partial pressure H₂O)² / (Partial pressure H₂)² . (Partial pressure NO)²

There is another expression for Kp, where you work with Kc (equilibrium constant)

Kp = Kc (R.T)^Δn

where R is the Ideal Gases constant

T° is absolute temperature

Δn = moles of gases formed - moles of gases, I had initially
