10) Arsenic is a chemical agent which was used in preserving dead bodies in the past. It is mainly a formaldehyde mixture with coloring agents to give a dead body the look of life. Sylvester was a third mummy that was embalmed with arsenic in the late 1800s and is now on exhibit at Ye Olde Curiosity Shop in Seattle, Washington. His mummified body showed an extremely unusual since the remains weighed approximately 80 lbs when a body is composed of 70-80% water, after dehydration, the weight should be about 20-30% the premortem weight. The solution was also used during Civil War to preserve dead bodies <span>as the dead were being shipped home from the battlefield.

9) R<span>esearch can yield dates when certain plants/animals became domesticated and entered the standard diets of people, meaning you would not see masses eating beef before the cow became domesticated. To further this you can look at when a specific food was introduced into the diets of people in the geographic area of the person you are studying. </span>
Answer:
136 neutrons
87 protons
Explanation:
A neutral atom have equal number of protons and neutrons. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The number of protons or number of electrons are the atomic number of an atom while the number of protons and number of neutrons are the mass number of an atom. Every atom consist of nucleus or a positive center. The protons and neutrons are present with in the nucleus while electrons are present out side the nucleus. All these three subatomic particles construct an atom.
Example:
In Francium the number of proton and neutron can be found by subtracting the atomic number of francium from its atomic mass. The atomic number will be the number of protons and remaining will show the total number of neutrons present in nucleus.
Atomic number is 87
Atomic mass 223
223- 87 = 136
So number of neutrons are 136 and number of protons are 87.
Answer:
Ionic Bonds: Electrons are transferred b/c one atom "steals" electrons from another. The attraction between the resulting cation/anion is known as an ionic bond.
Polar Covalent Bonds: Electrons are shared <em>unequally</em>. This is in the case that the molecule is not symmetric or if the central atom has a lone (electron) pair.
Nonpolar Covalent Bonds: Electrons are shared <em>equally</em>. This is in the case that the molecule is symmetric and the central atom has no lone pairs.
