The reaction between nitric oxide and oxygen is described by the following chemical equation: Suppose a two-step mechanism is pr

oposed for this reaction, beginning with this elementary reaction: Suppose also that the second step of the mechanism should be bimolecular. Suggest a reasonable second step. That is, write the balanced chemical equation of a bimolecular elementary reaction that would complete the proposed mechanism.

Answer:

2NO(g) + O2(g) ---> 2NO2(g)

Explanation:

The mechanism for this reaction involves two elementary reactions in which both are bimolecular as shown below;

NO(g) +O2(g) ----> NO2(g) + O(g)

NO(g) + O(g) ----> NO2(g)

Hence overall balanced reaction equation;

2NO(g) + O2(g) ---> 2NO2(g)

Dichlorine monoxide, Cl2O is sometimes used as a powerful chlorinating agent in research. It can be produced by passing chlorine
Amiraneli [1.4K]

Answer:

% yield =  82.5%

Explanation:

HgO + 2Cl₂ →  HgCl₂ +  Cl₂O

Our reactants are:

  • HgO and Cl₂

Our products are:

  • HgCl₂ +  Cl₂O

We do not have information about moles of reactants, but we do know the theoretical yield and the grams of product, in this case Cl₂O, we have produced.

Percent yield = (Yield produced / Theoretical yield) . 100

Theoretical yield is the mass of product which is produced by sufficent reactant. We replace data:

% yield = (0.71 g/0.86g) . 100 = 82.5%

Dilute solutions of NaHCO3 are sometimes used in treating acid burns.
Temka [501]

Answer:

We need 375 milliliters of 0.100 M NaHCO3 solution

Explanation:

Step 1: Data given

Initial molarity NaHCO3 = 0.100 M

Volume prepared solution = 750.0 mL

Molarity prepared solution = 0.05 M

Step 2: Calculate initial volume

C1*V1 = C2V2

⇒with C1 = the initial concentration = 0.100 M

⇒with V1 = The initial volume = TO BE DETERMINED

⇒with C2 = the new concentration = 0.0500M

⇒with v2 = the new volume = 750.0 mL = 0.750 L

0.100 M * V1 = 0.0500 M * 0.750 L

V1 = (0.0500M * 0.750L)/0.100 M

V1 = 0.375 L = 375 mL

We need 375 milliliters of 0.100 M NaHCO3 solution
