The answer is C: A surfer rides back to the beach on his surf board.

All the others are examples of people doing stuff to the water, C is an example of the water moving something, in this case the water is moving a surfer and his surf board.

Answer:

The correct answer is C) A surfer rides back to the beach on his surfboard.

Explanation:

This is the best answer because the other choices involve people moving things or moving themselves in a lake or the ocean. So if we want evidence that waves can cause objects to move, the wave must be the active part. Option C is correct because the surfer is passive. He or she is riding the surfboard but the waves are moving him or her.

Calculate the molarity of a solution of sodium hydroxide, naoh, if 23.64 ml of this solution is needed to neutralize 0.5632 g of
GuDViN [60]
The  molarity  of  NaOH  needed  is  calculated   as  follows
calculate  the  moles  of  KhC8h4O4

that  is  moles  =  mass/molar  mass  of  KhC8h4O4(204.22 g/mol)

=0.5632g /204.22g/mol=  2.76  x10^-3  moles

write the  equation  for  reaction

khc8h4O4  +  NaOH  ---> KNaC8h4O4  +  H2O

from  the  equation  above  the   reacting  ratio   of   KhC8h4O4  to  NaOh  is  1:1  therefore  the  moles  of  Naoh  is  also  2.76  x10^-3  moles

molarity  of NaOh  =  (moles  of  NaOh /  volume ) x  1000

that  is { (2.76  x10^-3) / 23.64}  x100  =0.117 M

A chemical reaction resulting in the transfer of electrons or hydrogen atoms from one molecule to another is called a(n) _______
anzhelika [568]

The kind of reaction involving the transfer of electrons or hydrogen away from a molecule is called oxidation.

In the same vein, the molecule that receives the electron or the hydrogen atom is said to be reduced. This means that oxidation cannot exist in isolation without reduction.

In other words, oxidation is defined as:

  • Loss of electrons
  • Loss of hydrogen atoms
  • Gain of oxygen atoms
  • Gain in oxidation number

While reduction is defined as:

  • Gain of electrons
  • Gain of hydrogen atom
  • Loss of oxygen atom
  • Reduction in oxidation number
