Answer:

A = 0.691g/cm³

B = liquid A at the bottom, liquid B in the middle and the cube at the top

Explanation:

Hello,

Density = mass / volume

Density = ?

Mass = 2.331g

Volume = ?

Length of the side = 1.5cm

Volume of a cube = L³

Volume of the cube = 1.50³

Volume = 3.375cm³

Density = mass / volume

Density = 2.331 / 3.375

Density = 0.691g/cm³

b) since the question doesn't require submitting a diagram, I would go ahead and answer it without any but explaining the basics for you.

Densities:

Liquid A = 1.004g/cm³

Liquid B = 0.6223g/cm³

Cube = 0.691g/cm³

If the three substance don't mix and are place in a granulated cylinder,

Liquid A would be at the bottom

Liquid B would stay at the middle

The cube would be at the top

Reason is that, when two immiscble liquid are placed in a container, the liquid with the higher density will stay at the bottom while that of lower will float on top.

If you did not use a watch glass to cover your stock iodine solution, and the concentration of iodine decreased over the course

anygoal [31]

Answer::

Lower rate of reaction

Explanation:

Lower concentration of reactant in an experiment is indicative of fewer ions or atoms present, which means a slower rate of reaction. In a titration reaction for instance, the end point would take longer to be substantiated, thereby increasing volume of titres. This is further backed up by collision theory which states that more particles in a system improves combinations of molecules.

This however may not be the case if the iodine in question is catalyst, in which case the change in concentration has no effect whatsoever on the reaction rte.

I hope this explanation fits the brief.

Which one of the following changes would cause the volume of a gas to double

Flauer [41]

Answer:

1) If the volume of a container is increased, the temperature increases.

2) If the volume of a container is decreased, the temperature decreases.

Explanation:

This means that the volume of a gas is directly proportional to its temperature.

pashok25 [27]

A cohesive force is best described as the attraction between two liquid molecules. Cohesive forces are the inter-molecular forces between similar molecules, which cause a tendency in liquids to resist separation. For example a water drop is composed of water molecules that like to stick together
