What is true that if at the same temperature 2 objects have equal masses, but different densities

Chemistry

Answer:

The two objects have different volumes.

Explanation:

The density of an object measures how closely packed the mass in the object is. Density of an object is obtained by taking the ratio of the mass of an object and its volume.

Density = mass/volume

The mass present in an object is constant, but the volume may vary with temperature. The volume of substances generally increases with temperature, therefore, density decreases with increase in volume.

Two objects at the same temperature having equal masses may or may not have the same density depending on the volume each object occupy.

If two substances are at the same temperature and have equal masses but different densities, then they must have different volumes.

What is the pH of a 0.00530 M solution of HCI?
MrMuchimi

Answer:

2.28

Explanation:

HCl(l) ===> H+ + cl-

HCl is a very strong acid. Almost all of it will decompose to the right. That means the concentration of H+ is 0.00530

pH = - log [H+]

pH = - log[0.00530]

pH = - - 2.2757

pH = 2.2757

Rounded this 2.28

Tara predicts the number of paper clips attracted by the magnet
muminat

The responding variable refers to the variable that changes as the independent variable is being manipulated. In this case, the responding variable is the number of paper clips attracted by the magnet.

An experiment must include a dependent (responding) variable and an independent variable. As the independent variable is manipulated during the experiment, the dependent (responding) variable changes accordingly.

In this case; the independent variable is temperature while the dependent (responding) variable is the number of paper clips attracted by the magnet.
