A combustion reaction occurs between one molecule of methane (CHa) and two molecules of oxygen (O2).
SCORPION-xisa [38]

The total number of atoms make up the products :

D) 1 carbon, 4 hydrogen, and 4 oxygen

<h3>Further explanation </h3>

Complete combustion of Hydrocarbons with Oxygen will produce CO₂ and H₂O compounds.

If O₂ is insufficient there will be incomplete combustion produced by CO and H and O

Hydrocarbon combustion reactions (especially alkanes)

For combustion of methane (CH₄) and two molecules of oxygen (O₂).

\tt CH_4+2O_2\rightarrow CO_2+2H_2O

The number of atoms make up the products

CO₂ : 1 carbon, 2 oxygen

2H₂O : 4 hydrogen , 2 oxygen

A weightlifter can lift 495 lbs. How many kg is that? Please provide a step-by-step procedure.
iogann1982 [59]

Answer:

Explanation:

2.2 pounds = 1 kg

495 pounds = x

2.2/495 = 1/x               Cross multiply

2.2*x = 495 * 1             Divide by 2.2

2.2x/2.2 = 495/2.2

x = 225 kg

Draw the alkyl bromide(s) you would use in a malonic ester synthesis of ethyl 3-methylbutanoate.
Gennadij [26K]

The structure of the alkyl bromides used in a malonic ester synthesis of ethyl 2-methyl-4-pentenoate.

Ethyl 2-methyl-4-pentenoate by Malonic ester synthesis.

The alkylation of diethyl malonate or a related ester of malonic acid at the carbon alpha (immediately next) to both carbonyl groups, followed by conversion to a substituted acetic acid, characterizes the chemical reaction known as the malonic ester synthesis.

As a result, it is evident from the structure of ethyl 2-methyl-4-pentenoate that ethyl and methyl bromides are the alkyl bromides employed.
