Montano1993 [528]3 years ago
7 0

Answer:

3

Explanation:

There are three different elements in given chemical equation. These elements are hydrogen, oxygen and carbon.

Chemical equation:

2CH₄ + 4O₂       →       2CO₂ + 4H₂O

This equation shows the burning of methane. When methane burns in the presence of oxygen it produced water and carbondioxide.

We can see that all the reactant and product are made up of only three elements carbon, hydrogen and oxygen.

There are two reactant and two products in given reaction.

This reaction also follow the law of conservation of mass.

We can see that there are two carbon eight hydrogen and eight oxygen  atoms on both side of equation.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

Identify which two compounds below are constitutional isomers
Romashka [77]

Answer:

(CH₃)₃COCH3₃ and (CH₃)₂CHOCH₂CH₃

Explanation:

Isomers are compounds which have the same molecular formula. Constitutional isomers have different connectivity; the atoms are connected in different ways.

1. (CH₃)₃COCH₃

2. (CH₃)₂CHOCH3₃

3. (CH₃)₂CHOCH₂CH₃

Molecules 1 and 3 have the same formula (C₅H₁₂O) and are isomers. Molecule 2 is not an isomer. From the structural formula, it is clear that Molecules 1 and 3 have different connectivity.
