Billy is trying to figure out what type of wood to use for building a model boat. He has a block of wood with a volume of 8.0 cubic centimeters (cm3) and a mass of 4.0 grams (g). What is the density of the block of wood in g/cm3 to the nearest tenth?

A 0.5
B 2.0
C 4.0
D 32.0

Answers

Answer:

A; 0.5

Explanation:

To find the density, you have to do the Mass divided by the Volume; in this case, it's 8.0/4.0.

8/4 = 0.5

Zinc has an average atomic mass of 65.37 amu. Jack is trying to figure out what the most abundant isotope of zinc is, but he doesn't have access to the internet, so the average atomic mass is the only information he has. Jack decides to made an educated guess as to the most abundant isotope of zinc by assuming there are only two isotopes of zinc. If Jack assumes there are only two isotopes of Zn, what he be most likely to decide is zinc's most abundant isotope?
Question 5 options:

Zinc-64


Zinc-65


Zinc-68


Zinc-66

Answers

Zinc's most abundant isotope : Zinc-65

Further explanation

Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.

So Isotopes are elements that have the same Atomic Number (Proton)

Atomic mass is the average atomic mass of all its isotopes

In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu

Mass atom X = mass isotope 1 . % + mass isotope 2.%

To decide zinc's most abundant isotope, then choose the closest mass number

or we can check the difference with the average mass number, if the value is the smallest, then that isotope has the largest abundant

Zinc-64

[tex]\tt \dfrac{65.37-64}{65.37}=0.021[/tex]

Zinc-65

[tex]\tt \dfrac{65.37-65}{65.37}=0.005[/tex]

Zinc-68

[tex]\tt \dfrac{68-65.37}{65.37}=0.04[/tex]

Zinc-66

[tex]\tt \dfrac{66-65.37}{65.37}=0.009[/tex]

The closest = Zinc-65(the smallest)

The answer is 5000 N

Explanation:

The force acting on a body can be found by using the formula

force = mass × acceleration

From the question

mass = 10 kg

acceleration = 500 m/s²

We have

force = 10 × 500

If the average atomic mass is 39.948amu, which isotope is more abundant?

Answers

Answer:

It depends on which element you are talking about. I appears that no element has an average atomic mass of that number. So, for the question, if it assumes that there are two isomers with 39 amu and 40 amu, then the 40 amu one would be more abundant. But again, there are different possible isotopes and I can't tell what the question wants.

Document 1- Excerpt from Indians are Us, by Ward Churchill (1994)In 1493 Columbus returned with an invasion force of seventeen ships, and was appointed by the Spanish Crown as governor of the Caribbean islands and the mainland of America, a position he held until 1500. Setting up shop on the large island he called Espanola (today Haiti and the Dominican Republic), he quickly developed policies of slavery (encomienda) and organized slaughter against the native Taino population. Columbuss programs reduced Taino numbers from as many as eight million at the beginning of his rule to about three million in 1496. Perhaps 100,000 were left by the time of his departure. His policies remained and by 1514 the Spanish census (population count) of the island showed barely 22,000 Indians remaining alive. In 1542, only two hundred were recorded. Thereafter, they were considered extinct, as were Indians throughout the Caribbean Basin, a total population which totaled more than fifteen million at the point of first contact with Columbus was now gone.Document 2- Excerpt from Columbus, Hero or Villain by Michael Pucci (1997)Contrary to what some say, Columbus was a courageous man. He challenged popular opinion when nobody else believed him. He did what no other explorer dared to do. He was determined to find the route to Asia when everybody else was afraid to. American Indian activists criticize Columbus for bringing disease to America and act as if that was his entire goal when setting sail from Europe. It is ridiculous to claim that he knowingly brought over these sicknesses and purposely infected people with it. Columbus is also slammed for owning slaves. What leader in 1492 did not own slaves? The fact that Columbus did own them is irrelevant to any issue. Columbus did not cause environmental destruction either. He paved the path for the settlement of America. Columbus was not on a mission of destruction. Rather, he was on a quest for paradise.1- What is the point of view expressed in both documents concerning Christopher Columbuss interactions with the indigenous people?
