The oxidation of magnesium to form magnesium oxide is shown by which balanced chemical equation?
a) mg(s) + o2(g) → mgo(s)
b) 2mg(s) + o2(g) → 2mgo(s)
c) 2mgo(s) → 2mg(s) + o2(g)
d) 2mg(s) → 2mgo(s) + o2(g)

Answer : The correct balanced chemical reaction will be,

(B)

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

Synthesis reaction : A chemical reaction where multiple substances or reactants combine to form a single product.

It is represented as,

The balanced chemical reaction will be,

your answer would be a. 12.5 kg

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
