Answer:
2
Explanation:
the pH of the strong acid solution will be
pH = -log[H+] = -log[0.01] = 2
Answer:
2= its color
Explanation:
Transition elements are present in the middle of periodic table. These are d-block elements.
These are 38 elements.
All transition elements have partially filled d orbitals.
They showed color in compound because of d-d transition.
During the d-d transition electron absorbed the energy and emit the reminder energy. The emission is usually in the form of color light.
The color of ion is complementary to the absorbed color.
The transition elements are used as a catalyst in industries such as polymer, petroleum industries.
They are ductile, conduct heat and electricity.
Hey there!
2Na + Cl₂ → 2NaCl
This is a balanced chemical equation.
There are 2 atoms of sodium (Na) on the left, and 2 atoms of sodium (Na) on the right.
There are 2 atoms of chlorine (Cl) on the left, and 2 atoms of chlorine (Cl) on the right.
This means the equation is balanced since there are the same amount of each element on both sides.

Answer: <span>Yes, a hydrocarbon is any compound that contains hydrogen and oxygen.
Justification:
First, I will try to rewrite the given structural formula since it is misrepresented.
This should be the right structural formula:
H H
| |
H - C - C - OH
| |
H H
And, yes the definition of hydrocarbon is that it is most simple organic compound constitured only by atoms of carbon (C) and hydrogen (H).
By the way, that hydrocarbon is also represented as CH3 - CH2 OH, it is an alcohol (since it has the functional group OH) and its name is ethanol.
