The combustion of ammonia produces NO and water. If the chemical reaction for this process is properly balanced using the smalle
cestrela7 [59]

Answer:

10

Explanation:

The unbalanced combustion reaction is shown below as:-

NH_3+O_2\rightarrow NO+H_2O

On the left hand side,  

There are 3 hydrogen atoms and 1 nitrogen atom and 2 oxygen atoms

On the right hand side,  

There are 1 nitrogen atom and 2 hydrogen atoms and 2 oxygen atoms

Thus,  

Right side, H_2O must be multiplied by 6 to balance hydrogen.

Left side, NH_3 must be multiplied by 4 to balance hydrogen.

Also, Right side, NO is multiplied by 4 so to balance nitrogen.

Left side, O_2 must be multiplied by 5 to balance the whole reaction.

Thus, the balanced reaction is:-

4NH_3+5O_2\rightarrow 4NO+6H_2O

Sum of Coefficient of product - 4 + 6 = 10

According to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in which order?
Scilla [17]

According to the IUPAC convention alkyl substituents on a hydrocarbon chain should be listed in alphabetical without considering prefixes order.

<h3>What is IUPAC convention?</h3>

IUPAC convention of organic chemistry is a method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC).

The name of the compound is written out with the substituents in alphabetical order followed by the base name (derived from the number of carbons in the parent chain).

Types of IUPAC  Nomenclature of a few important aliphatic compounds:

  1. Alkane
  2. Alkene
  3. Alkyne

Example :

Ethane, which has 2 carbon atoms and 6 hydrogen atoms, with the molecular formula of = C₂H₆

Formation of alkyl group:

Methane (CH₄)  Remove 1 hydrogen (H) convert to methyl (H₃-C-)

Example: Propyl (-CH₃ - CH₂ - CH₂ - )

According to the IUPAC convention alkyl substituents on a hydrocarbon chain should be listed in alphabetical without considering prefixes order.

Given an initial cyclopropane concentration of 0.00560 m, calculate the concentration of cyclopropane that remains after 1.50 ho
maria [59]

<span>We can solve this problem by assuming that the decay of cyclopropane follows a 1st order rate of reaction. So that the equation for decay follows the expression:</span>

A = Ao e^(- k t) 

Where,

A = amount remaining at time t = unknown (what to solve for) <span>
Ao = amount at time zero = 0.00560 M </span><span>
<span>k = rate constant
t = time = 1.50 hours or 5400 s </span></span>

The rate constant should be given in the problem which I think you forgot to include. For the sake of calculation, I will assume a rate constant which I found in other sources:

k = 5.29× 10^–4 s–1                     (plug in the correct k value)

<span>Plugging in the values in the 1st equation:</span>

A = 0.00560 M * e^(-5.29 × 10^–4 s–1 * 5400 s )

A = 3.218 <span>× 10^–4 M           (simplify as necessary)</span>
