Answer:
According to Newton's second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known.

Answer:
New temperature T2 = 16.59°C Approx
Explanation:
Given:
Old volume V1 = 2.36 L
Old temperature T1 = 27°C
New volume V2 = 1.45 L
Find:
New temperature T2
Computation:
Using Charles's Law;
V1T2 = V2T1
(2.36)(T2) = (1.45)(27)
New temperature T2 = 16.59°C Approx
Answer:
The answer is most likely A. Definite proportions
Explanation:
The Law of Definite proportions states that a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.
Answer is: near equivalence point indicator should change color, so we must pick indicator who changes color near pH of equivalence point.
Equivalence point is
the point which there is stoichiometrically equivalent amounts of acid and
base. <span>
<span>Chemist can draw pH curve (graph
showing the change in pH of a solution, which is being titrated) for
titration and determine equivalence point.</span></span>
