Answer:
When white light falls upon a green surface all of the components of the white light that are not green are absorbed by the surface while the green light is scattered.
Explanation:
Answer:
Third Law of motion. (answer C)
Explanation:
This is an example of Newton's Third Law of motion which normally translates into Action/Reaction. That is : the expelled air exerts a force in the direction opposite to that of the motion of the air that goes out. It is the same as propulsion in a rocket.
<u>Explanation:</u>
We are given a mixture of hydrochloric acid (HCl) and acetic acid
. The given mixture is a mixture of strong acid and a weak acid.
Strong acid is defined as the acid that can be get completely ionized or dissociated in an aqueous solution. Weak acid is defined as the acid which does not dissociate completely in an aqueous solution.
When a mixture of HCl and
is titrated against NaOH (strong base), strong acid will get neutralized first because it is completely dissociated in the solution and can be easily neutralized.
Answer : The type of reaction described in the sentence is Synthesis or Combination
Explanation :
The balanced equation for the reaction between Phosphorous and Oxygen gas can be written as
![4P (s) + 5O_{2} (g) ------> P_{4} O_{10} (s)](https://tex.z-dn.net/?f=%204P%20%28s%29%20%2B%205O_%7B2%7D%20%28g%29%20------%3E%20%20P_%7B4%7D%20O_%7B10%7D%20%20%28s%29%20)
From the above equation we can see that there are two different reactants ( P and O₂ ) which are combining with each other to give a single product.
This type of reaction is known as Combination or Synthesis.
A general form of Synthesis reaction is given below.
![A + B ----> AB](https://tex.z-dn.net/?f=%20A%20%2B%20B%20----%3E%20%20AB%20)
Here we can conclude that a synthesis / combination reaction is the one where 2 or more reactants combine together to give only one product .
C. An atom of helium has its valence electrons in its first energy level, it wouldn't and can't satisfy the Octet rule as it only has 2 electrons, but with 2, it has a full shell, as the first energy level can hold only 2 electrons.
