trapecia [35]

Explanation:

The balanced chemical equation is given as:

              2H₂O₂  →  O₂  +  2H₂O

А  There are two peroxide molecules on the reactant side.

The statement is correct because the left hand side is the reactant side. We can read the reaction as;

   2 molecules of hydrogen peroxide decomposed  to given 1 molecule of oxygen gas and 2 molecules of water .

D Mass must be conserved so there are an equal number of molecules in the reactants and products.

E Mass must be conserved so there are an equal number of atoms in the reactants and products.

Since the chemical equation is balanced, choices D and E are correct. The reaction will have equal number of molecules and atoms on both sides of the expression.

A child slides down the water slide at a swimming pool and enters the water at a final speed of 4.22 m/s. At what final speed wo
zheka24 [161]

Answer:

v'=5.97 m/s        

Explanation:

If the friction and fluid friction are ignored, then by law of conservation of mechanical energy, potential energy at the top of the slide must be equal to the kinetic energy at the bottom of the slide. Thus, the height of slide and final speed at the bottom of the slide are related as:

mgh = \frac {1}{2} mv^2\\v =\sqrt{2gh}

let the final speed be v' when h' = 2 h

\frac{v'}{v}=\frac{\sqrt h'}{\sqrt h}\\v'=\sqrt{\frac{2h}{h}}\times v\\v'=\sqrt2 v\\v'=5.97 m/s

What evidence can you cite to support the claim that the frequency of light does not change upon reflection?
soldier1979 [14.2K]

Answer: The color of an image is equal to the color of the item forming the picture. When you have a take a observe your self in a mirror, the color of your eyes would not alternate. The reality that the color is equal is proof that the frequency of light would not alternate upon reflection.
