AURORKA [14]3 years ago

Answer:

Explanation:

The law of conservation of mass states that "mass in a system remains constant and that the mass of the product is remains the same as that of the reactants".

Law of conservation of energy states that "energy is neither created nor destroyed in the course of chemical or physical change but can be transformed from one form to another".

 Let us properly write the equation:

               CH₄ + 2O₂ → CO₂ + 2H₂O

For the conservation of mass:

  C has 1mole on both sides

   H has 4mole on both sides

   O has 4 mole on both sides

For energy, during combustion process, the methane CH₄ burns to liberate heat energy. This is an energy conversion process in which chemical energy in methane releases heat energy.

Electronegativity _____. generally increases moving from left to right across a period generally decreases moving from left to r
mojhsa [17]
I believe the correct answer would be that electronegativity generally increases moving from left to right across a period. The periodic table of elements is arranged so that trends of the properties of the elements can be shown. For electronegativity, it decreases from right to left which means for the opposite direction it increases.
