Answer : The correct option is, The positive ion

Explanation :

The rules for naming the ionic compounds is given as :

  • The positive ion (cation) is written first.
  • The negative ion (anion) is written next.
  • The suffix is added at the end of the negative ion (anion). The suffix used is '-ide'.

As per question, the first word in the name of a binary ionic compound represent the positive ion and then the negative ion.

For example : NaCl is the binary ionic compound that composed of two different elements which are Na and Cl. The name of this compound is, Sodium chloride.

Hence, the correct option is, The positive ion

Automobile catalytic Converters use a platinum callus to reduce air pollution by changing emissions such as carbon monoxide CO2
natka813 [3]

Answer:

14 mol O₂

Explanation:

The reaction between CO and O₂ is the following:

CO + O₂ → CO₂

We balance the equation with a coefficient 2 in CO and CO₂ to obtain the same number of O atoms:

2CO + O₂ → 2CO₂

As we can see from the balanced equation, 1 mol of O₂ is required to react with 2 moles of CO. Thus, the conversion factor is 1 mol of O₂/2 mol CO. We multiply the moles of CO by the conversion factor to calculate the moles of O₂ that are required:

28 mol CO x 1 mol of O₂/2 mol CO = 14 mol O₂

Convert 44.8 liters of CO2 into particles of CO2​
jonny [76]

Answer:

1.2044 x 10^24 particles

Explanation:

Assuming this is<u> STP</u>....then this is 2 moles    ( each mole = 22.4 L/mole)

  2 moles = 2 * 6.022 x 10^23  = 1.2044 x 10^24

Consider the formation of nitrogen dioxide and oxygen: NO(g)+O3(g)⇌NO2(g)+O2(g) The reaction is first order in O3 and second ord
Leno4ka [110]

Answer:

The rate law is rate = k[NO][O₃]

Option E) is the right answer.

Explanation:

Hi there!

For this generic reaction:

A + B → products

the rate law will be:

rate = k[A]ⁿ[B]ᵃ

this reaction is n-order in A and a-order in B. The overall reaction is the sum of the orders of each reactant, in this case:

Overall order of the reaction = n + a

In our problem, we know that the reaction is first order in O₃ and second order overall. Then:

Overall order of the reaction = Order in NO + Order in O₃

2 = n + 1

2 - 1 = n

n = 1

Then, the reaction is first order in NO and first order in O₃.

The rate law will be:

rate = k[NO][O₃]

The right answer is the option E).
