To minimize the sharp pH shift that occurs when a strong acid is added to a solution, IT IS PRACTICAL TO ADD A WEAK BASE.
When a strong acid is added to a solution, it usually brings about a sharp change in the pH of the concerned solution. To avoid this, one can add a weak base to the solution first. The weak base will serves as a buffer for the strong acid and prevents the solution from experiencing sharp pH variations.
The muscles of the body are part of the musculoskeletal system but would not operate without the nervous system providing the impulses that cause the muscles to act. Correct answer: C The nervous system controls all activities within the human body, including the muscles. It sends messages between the brain and the muscles very quickly using nerve impulses (action potentials).
Answer:
The Lewis structure of CH3OCH3 is dimethyl ether, the simplest ether in existence
Explanation:
<h2>
Hello!</h2>
The answer is: Charle's Law.
<h2>
Why?</h2>
The law that states that the volume and absolute temperature of a fixed quantity of gas (ideal gas) are proportional under constant pressure is the Charle's Law, also known as the law of volumes.
The law describes how a gas kept under constant pressure tends to expand when the temperature increases and it's described by the following equation:
Where,
Also, to describe the relationship between two differents volumes at different temperatures, we have:
Where,
Have a nice day!
Force: any interaction that, when unopposed, will change the motion of an object.
Mass: the quantity of matter in a body regardless of its volume or of any forces acting on it
Acceleration: rate of change of velocity of an object with respect to time
