Answer;
-The most accurate measurement is made by;
C. Dr. Smith, who measures 13.54 g/mL.
Explanation;
-The absolute density (how much a given volume of the substance weighs) of mercury is 13593 kilograms per cubic meter. It can also be stated as 13.56 g/cm^3. Accuracy measures the nearness of a calculation to the true value.
-In this case; the measurement by Dr. Smith is near the true value 13.56 g/cm^3, as compared to the measurements by other scientists.That is Dr. Chopra, who measures 13.487 g/mL. Dr. Thompson, who measures 13.5 g/mL. and Dr. Tyler, who measures 13.9336 g/mL.

According to Charle's law, the new volume of the balloon will be 600 cm³ if pressure is kept constant.
Charles law is an experimental gas law which provides description about the behavior of gases which tend to expand on heating.It states that, at constant pressure, the temperature is in direct proportion with the volume that is,V∝T or V₁/T₁=V₂/T₂.The relation between volume and temperature is linear as the temperature increases volume also increases.
The graph of volume versus temperature is a straight line passing through the origin.The law was proposed by Jacques Charles in relation to ideal gases.
Substitution of the given values in the given formula, V₂= 200×180/60= 600 cm³.
Thus, the new volume of the balloon will be 600 cm³ if pressure is kept constant.

Let x represent the new volume:
cross multiply:
then simplify to get 600cm^3
Hope this helps :)
Answer: The isotope will be represented by symbol .
Solution:
The isotope of an element is represented by:
X = Symbol of an element
Z = Atomic Number of that element = Total number of electrons or protons
A = atomic mass of that element = Z+ total number of neutrons
So the uranium isotope with atomic mass of 238 and atomic number of 92 will be written as:

B. 238/92 U

Explanation:
The plum pudding model of the atom by the scientist Sir Joseph John Thompson or J.J. Thompson. It was theorized after the discovery that electrons are present in the atom. In this model, the atom is composed mainly of electrons. It was describe as plum pudding because the electrons are dispersed within the atom. John Dalton discovered the atom. Ernest Rutherford discovered the half – life of an atom and Neils Bohr explain the quantum mechanics. So the answer is J.J. Thompson.
