Answer: The coefficient for water after the equation is balanced is 2.
Explanation:
The balanced chemical equation must have same charge and same number of atoms on both sides of the equation.
As the given reaction is a redox recation occuring in acidic medium.
The coefficient for water will be 2 after the equation is balanced.
The compound HClO4, when placed in water, will dissociate into the ions, H+ and ClO4-. Therefore, the 2.0 M solution will also form 2.0 M H+. The pH is calculated through the equation,
pH = -log[H+]
Substituting,
pH = -log[2] = -0.3
Thus, the pH of the solution is -0.3.
Answer:
A line can be lyrically defined as a point in motion. ... They help determine the motion, direction and energy in a work of art. We see line all around us in our daily lives; telephone wires, tree branches, jet contrails and winding roads are just a few examples.
True.
One of the definitions of a square is that it is a rectangle with all sides congruent. Hence, every square, by definition, is a rectangle.
