Answer:
They don't move
Explanation:
it may look like they move but you are moving and you are passing the objects so they are not moving other wise things like some trains or animals they move with you. I hope this helps! :D
<h3>
Answer:</h3>
A. It is a very strong base.
<h3>
Explanation:</h3>
To answer the question we need to ask ourselves several questions
What is pH?
- pH refers to the measure of alkalinity or acidity of a substance.
How is pH measured?
- pH is measured by determining the concentration of Hydrogen ions (H⁺) in a given solution.
- Then calculated by getting negative logarithm of hydrogen ions concentration.
- That is, pH = -log[H⁺]
What does pH tell about a solution?
- A solution with a pH below 7 is acidic while a solution with a pH above 7 is basic while that with a pH of 7 is neutral.
- A pH of 1 to 3 represents a strong acid while a pH of 4 to 6 represents a weak acid.
- Strong alkali or bases have a pH of 12 to 14 while weak alkali or bases have a pH of 8 to 11.
- Therefore, a solution with a pH of 14 is a very strong base
Answer:
Option b=> 0.1 M CH3COOH , 0.1 M CH3COONa.
Explanation:
In chemistry, when an acid or a base(alkali) is added to a solution and the solution pH does not change then we say that the solution is a BUFFER SOLUTION (that is a solution, upon the addition of acid or base will show resistance in pH value).
In order to be able to answer this question efficiently we have to consider the mathematical representation or Equation below;
pH = pKa + log ( [ A^-] / [HA] )--------------------------------------------------------------------(1).
What the mathematical representation or Equation (1) above is telling is is that if [A^-] or [HA] is high then there will be the production of buffer with higher buffer capacity.
Answer:soda
Explanation:A homogeneous mixture is a mixture in which individual components of the mixture cannot be identified and since individual components of soda cannot be identified it is a homogeneous mixture
The structures and chemistry of individual hydrocarbons depend a large part on the types of chemical bonds that link together the atoms of their constituent molecules. Hydrocarbons are derived by chemical degradation.
