Answer:
Physical
Explanation:
The change of density alone is a physical change, but there might be some chemical change that results in physical change. For example: Burning a piece of paper will definitely change the density of the paper as some of its content is being changed into smoke which is a gas. So there will be a change in volume which in turn leads to change in density. Therefore, the change of density alone is a physical change, but the change might occur due to another chemical change.

A compound differs from an element in that it can be decomposed by a chemical reaction.
A compound, by definition, is made up of two or more elements that have been combined together through a chemical bond.
Thus, the chemical bond or bonds in a compound can be decomposed by a chemical reaction giving rise to the individual elements that make up the compound.
This is unlike an element that can not be decomposed by any chemical reaction.

Answer:
Understanding the unit cell of a crystalline solid will help you in determining the empirical formula of the ionic solid compound because they both represent the smallest portion of the whole crystalline solid proportion.
Explanation:
A unit cell is the smallest portion of a crystal lattice, that can show the 3 dimensional pattern of the whole crystal.A formula unit is the lowest whole number ratio of ions in a an ionic compound.By considering the smallest repeating units/ unit cell, you can describe the structure of a crystalline solid.Knowing this can help in determining the empirical formula of the ionic solid compound.
Looking for evidence entails careful study. The answers to the question is below;
<h3>Evidence and Fact finding</h3>
The crime that Mr. Fraser describes is drive-by killing.
The police select their suspect by the act of showing pictures to one of the teenagers and thereafter they the suspect out, the suspect the saw that shoot the father.
The fact was that there was no evidence since they did not find the gun and the car used in the crime was not identified. Even the suspect vehicle (shooter) was not identified also.
The approximate figure is about 252 out of 367 cases of wrongful conviction have been identified. That is 69% of DNA exonerations. Others about 250-285 cases.
The National Registry of Exonerations has stated that about 450 non-DNA-based exonerations where there was eyewitness misidentification. That is about 3 quarters have eye witness testimonies.
Reconstructive memory is simply known as the act of remembering that involves the reproduction of an experience or event that is known to be partially stored in memory before.
Fraser challenged the judge to go out and inspect the crime scene themselves.
The outcome of the challenge was that the judge thereby granted the retrial for Francisco Carrillo and thus released him so he can prepare his defense before the prosecution day.
Mr. Fraser suggested that people learn to be more effective with how they handle things or situations so as to get the right evidence and also that people be more cautious about how true some eyewitness testimonies may be.
