4 0
Balancing the equation, we get:

2C₂H₆O + O₂ → 2C₂H₄O₂ + 2H₂O

So 
α = 2
β = 1
γ = 2
δ = 2

Nitrogen dioxide reacts with carbon monoxide to produce nitrogen monoxide and carbon dioxide. NO2(g) + CO(g) ⟶ NO(g) + CO2(g) A
Naya [18.7K]

<u>Answer:</u> The rate law for the reaction is \text{Rate}=k[NO_3][CO]

<u>Explanation:</u>

Rate law is defined as the expression which expresses the rate of the reaction in terms of molar concentration of the reactants with each term raised to the power their stoichiometric coefficient of that reactant in the balanced chemical equation.

In a mechanism of the reaction, the slow step in the mechanism determines the rate of the reaction.

For the given chemical reaction:

NO_2(g)+CO(g)\rightarrow NO(g)+CO_2(g)

The intermediate reaction of the mechanism follows:

Step 1:  2NO_2(g)\rightleftharpoons NO_3(g)+NO(g);\text{ (fast)}

Step 2:  NO_3(g)+CO(g)\rightarrow NO_2(g)+CO_2(g);\text{(slow)}

As, step 2 is the slow step. It is the rate determining step

Rate law for the reaction follows:

\text{Rate}=k[NO_3][CO]

Hence, the rate law for the reaction is written above.

A salt crystal has a mass of 0.17 mg . how many nacl formula units does it contain?
Llana [10]
<span>1. Calculate the mass of the formula unit (fu). Na= 22.990 g/mol Cl= 35.453 g/mol so total = 22.990 g/mol + 35.453 g/mol = 58.443 g/mol 1 mol = 6.02 x10^23 formula units, so (58.443 g/mol)*(1 mol/6.02x10^23 fu)= 9.7x10^-23 2. Convert mass to grams: (0.17 mg)*(1 g/1000 mg) = 0.00017 g 3. Calculate number of formula units: 0.00017 g x (1 fu/9.7x10^-23 g) = 1.8x10^18 Or more simply: (.00017 g) * (1 mol/58.443 g) * (6.02x10^23 fu/1mol) = 1.8x10^18</span>

What’s the mass of a substance that’s density is 100.09g/mL and takes up 52.75mL?
Leokris [45]
Answer: 5,279.7475g

Mass = Density x Volume
Fill in the blanks :D
Mass= 100.09g/mL x 52.75mL

The mL cancels out and you multiply the numbers.
Mass= 5,279.7475 g

A control. during a experiment
timama [110]

A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.

Hatshy [7]
<span>P1*V1=P2*V2

you are given the pressure (P1) and your first volume (V1) and your final volume (V2) and you need to solve for P2 or your final pressure.

164KPa*2.25L=P2*1.50L
P2=246KPa</span>
