The image shows the combustion of methane. Which equation represents this chemical reaction? A. CH4 + O2 → CO2 + H2O B. 2CH4 + 2O2 → CO2 + 2H2O C. CH4 + 2O2 → 2CO2 + H2O D. CH4 + O2 → 2CO2 + 2 H2O E. CH4 + 2O2 → CO2 + 2H2O

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

i think slash and

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
