Answer:
a. What would be the expected pH if a Student A accidentally diluted 9.1 mL (instead of 9.0 mL) of the acid to 100 mL? = 2.7423
b. If student A measured the above calculated pH, what would be the resultant K of acetic acid given that they expected the acid to have an initial concentration of 0.18M. = 1.838 x 10 ∧-5

I know for sure volcanos are formed
Answer:
As a result, Sofa's acceleration was 2 m/s² according to Newton's Second Law of motion.
Explanation:
Newton's Second Law, also called the Fundamental Law of Dynamics, indicates that: "The change in motion is directly proportional to the printed motive force and occurs according to a straight line along which that force is printed." This means that the acceleration of a moving object depends on the amount of force applied to it at a given moment, in order to modify its trajectory or speed.
So, Newton's second law states that a body accelerates if a force is applied to it. The acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object:
F = m * a
where "m" is the mass of the object, "a" is the acceleration and "F" is the net force, that is, the vector sum of all the forces acting on the object.
In this case:
Replacing:
300 N = 150 kg*a
Solving;
300 N÷ 150 kg=a
2 m/s²=a
<u><em>As a result, Sofa's acceleration was 2 m/s² according to Newton's Second Law of motion. </em></u>
2 F atoms
Explanation:
A Ca atom has a valence number of +2, which means that when ionized, it will give up two electrons. In turn, a F atom has a valence number of -1, which means it can only accept 1 electron when ionized. So to accommodate the two electrons from Ca atom, we need 2 F atoms.
