Consider the reaction: 2nh3(aq)+ocl−(aq)→n2h4(aq)+h2o(l)+cl−(aq) this three-step mechanism is proposed: nh3(aq)+ocl−(aq) ⇌k1k2 n
saw5 [17]

Yes, the mechanism sums to the reaction.

You add the equations, cancelling species that occur on opposite sides of the arrows.

<em>Eq1</em>: NH3(aq) + OCl^(-)(aq) → <u>NH2Cl(aq)</u> + <u>OH^(-)(aq)</u>

<em>Eq2</em>: <u>NH2Cl(aq)</u> + NH3(aq) → <u>N2H5^(+)(aq)</u> + Cl^(-)(aq)

<em>Eq3</em>: <u>N2H5^(+)(aq)</u> + <u>OH^(-)(aq)</u> → N2H4(aq) + H2O(l)

<em>OA</em>: 2NH3(aq) + OCl^(-)(aq) → N2H4(aq) + H2O(l) + Cl^(-)(aq)

Ann and Carol each lift the timber with a force of 80 kg/m/s2. If they lift the timber a distance of 1.25 meters, how much work
Novosadov [1.4K]
Work is defined energy transferred from one to another. 
The formula for work done is work done = force x distance

So in our problem, force is equal to 80 kg/ m / s^2 and distance is equal to 1.25 meters. So plugging in our values will give us:

work done = 80 kg/ m/ s^2 * 1.25 m
= 100.00 J is the answer.
