Answer:

The  net ionic equation for the overall reaction is

          H_2C_2O_4{(aq)} + 2OH^-_{(aq)} ----> C_2O_4^{2-}_{(aq)} + 2H_2O_{(l)}

Explanation:

The molecular formula for sodium hydroxide is  NaOH while the molecular formula for oxalic acid is given as (H_2 C_2 O_4)

   Now the balanced chemical equation for this reaction is

           H_2C_2 O_4_{(aq)} + 2NaOH_{(aq)}  ---->  Na_2C_2O_4_{(aq)} + 2H_2O_{(l)}

The procedure for the ionic equation is

    H_2 C_2O_4 _{(aq)} + 2 Na^+ _{(aq)} + 2OH^-_{(aq)} ---->2Na^+ _{(aq)}  + C_2O_4^{2- }_{(aq)} + 2H_2O_{(l)}

Here Na^+ is the sodium ion

       OH^- is the hydroxide ion

       C_2O_4^{2-} is the oxalate ion

Note: The dissociation of oxalic equation is not complete because it is a weak acid

Looking at this equation we see that Na^+ is common on both sides of the equation so we cancel it out so the equation becomes

           H_2C_2O_4{(aq)} + 2OH^-_{(aq)} ----> C_2O_4^{2-}_{(aq)} + 2H_2O_{(l)}

A possible mechanism for the gas phase reaction of NO and H2 is as follows: Step 1 2NO N2O2 Step 2 N2O2 + H2 N2O + H2O Step 3 N2
mel-nik [20]

Answer: Option (d) is the correct answer.

Explanation:

Steps involved for the given reaction will be as follows.

Step 1: 2NO \Leftrightarrow N_{2}O_{2}    (fast)

Rate expression for step 1 is as follows.

               Rate = k [NO]^{2}

Step 2: N_{2}O_{2} + H_{2} \rightarrow N_{2}O + H_{2}O

This step 2 is a slow step. Hence, it is a rate determining step.

Step 3. N_{2}O + H_{2} \rightarrow N_{2} + H_{2}O    (fast)

Here, N_{2}O_{2} is intermediate in nature.

All the steps are bimolecular and it is a second order reaction. Also, there is no catalyst present in this reaction.

Thus, we can conclude that the statement step 1 is the rate determining step, concerning this mechanism is not directly supported by the information provided.

The image formed by a lens may be real or virtual. The image formed by a lens is always virtual.
amid [387]
There are types of lens; concave and convex lens.
The concave lens is a lens which has an inward curve in the middle, that is, the edges of the curve are thicker than the center of the lens, because of this, any light that enter the lens will spread out [diverge]. An image will look smaller and upright when viewed by a concave lens. Image formed by concave lens are usually VIRTUAL. 
A concave lens will produce a real image ONLY if the object is located beyond the focal point of the lens.
A convex lens is a converging lens, this is because, the center of the lens is thicker than its edges. Any ray of light that passes through the lens will converge at the middle of the lens at point called principal focus.  A convex lens produce a VIRTUAL image when the object is placed infront of the focal point. The virtual image formed is always magnified and upright.<span />
