THIS IS 7TH GRADE SCIENCE. PLEASE HELP ME ILL MARK BRAINLIEST HEP! :( Write a short paragraph on this concept: You are a superhero that invented a machine that can control gravity (make it stronger or more weak). Tell about why you made it and the kinds of things you would use it for (you must include one way you would use it to increase gravity and one way to weaken gravity) and why you would do it.

Explanation:

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
