Explanation:
All matter is made of atoms. Which drawing shows the correct relationships between the three
basic parts of an atom?
Answer:
This question is incomplete.
Explanation:
This question is incomplete. However, an atom (as shown in the attachment) is made up three main sub-parts/basic parts namely; protons, neutrons and electrons.
A proton is positively charged and it's found in the nucleus of the atom.
A neutron has no charge and is also found in the nucleus of the atom.
Both the proton and neutron contribute to the mass of an atom; hence the mass number of an atom is the addition of the neutrons and protons. The nucleus is located at the center of the atom (usually represented with a dot) and it's positively charged because it contains just the proton and the neutron.
An electron is negatively charged and it's found orbiting the nucleus of the atom.
NOTE: The atom in the attachment is that of a helium atom. There are two labels there; however, one of those labels (nucleus) is the standard representation for two basic parts of atom (protons and neutrons) as explained earlier.
The drawing that displays the adequate association between the 3 foundational parts of the atom would be:
e- (outside)
p+ & n⁰ (nucleus/inside e-)
Parts of an Atom
An atom comprises of various parts i.e. Protons along with Neutrons and Electrons.
As per the question, the above diagram most effectively shows the association between these three basic parts.
The electron lies outside the shell while the nucleus and the proton with +ve charge would be as mentioned above.

A mystery element’s mass spectrum shows it to be 13.92 % Isotope A (219 amu), 72.16
% Isotope B (222 amu), and 13.92 % Isotope C (225 amu).
a. What is the atomic weight of the element?
b. What is the element?
Answer:
The given element is Radon because its atomic weight is 222 amu.
Explanation:
Given data:
Percentage of A-219 = 13.92%
Percentage of B-222 = 72.16%
Percentage of C-225 = 13.92%
Atomic weight of element = ?
Solution:
Average atomic mass = (abundance of A isotope × its atomic mass) +(abundance of B isotope × its atomic mass) + (abundance of C isotope × its atomic mass) / 100
Average atomic mass = (13.92×219)+(72.16×222) + (13.92×225)/100
Average atomic mass = 3048.48 + 16019.52 +3132/ 100
Average atomic mass = 22200 / 100
Average atomic mass = 222 amu.
The given element is Radon because its atomic weight is 222 amu.

Explanation:
There is 35 mg of sodium in a can of Coke. You determine it to be 28 mg. What is your percent error?
%
Answer:
The answer is
20 %Explanation:
The percentage error of a certain measurement can be found by using the formula
[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]
From the question
actual volume = 35 mg
error = 35 - 28 = 7
The percentage error is
[tex]P(\%) = \frac{7}{35} \times 100 \\ = \frac{1}{5} \times 100 \\ = 20[/tex]
We have the final answer as
20 %Hope this helps you
Answer:
20%
Explanation:
The formula is [ |va-ve/ve| * 100% ] where e = error and n = number.
|28-35/35| * 100
|-7/35| * 100%
|-1/5| * 100%

Explanation:
Graphs are tools that help in performing calculations as they reduce the source of errors which is done in long mathematical calculations.
What are errors?
Errors in chemical analysis result when there is a difference between observed value and the true value.If the magnitude of errors is large , it results in decrease in accuracy, reproducibility, and precision.
There are three types of errors:1) random error 2) systematic error 3) human error.The cause of random errors are difficult to quantify while the human errors can be minimized by taking a range of readings to reduce the error.
Errors while measuring boiling point may be human errors while noting down the boiling temperature or instrumental or systematic error if there is a fault in the thermometer.

Carrie is making a presentation on solar winds. Her notes of the steps that must occur for solar winds to form are below. 1. The stream of electrically charged particles collide with gas atoms, causing the latter to give off light. 2. The electrically charged particles flow outward in all directions as far as Saturn. 3. The stream of electrically charged particles flows outward from the corona. 4. The particles of the solar wind flow along lines of the magnetic field. Which shows the correct sequence in the formation of solar winds? 1, 2, 3, 4 2, 3, 4, 1 3, 2, 4, 1 4, 2, 1, 3
Answer: 1, 3,4,2
Explanation: Solar Wind is a stream of charged particles, called Plasma, released from the surface of the sun. It is formed by the expansion of plasma from the Sun's outermost surface, known as Corona.
Inside the Sun, 4 atoms of hydrogen transform into Helium by a nuclear reaction called Fusion. This reaction produces energy, which travels to the surface. There, it decomposes into plasma, where it continues to heat up.
When the Sun's gravity can't hold it down, the gas streams along the Sun's magnetic field line. Because of the rotation of the Sun, the lines form huge spiral, creating a constant flow of "wind". They extend so far, it generates an interplanetary magnetic field (IMF), which surrounds all the planets in our solar system.

This text explains a cause-and-effect pattern in the Hudson River ecosystem that began with the zebra mussel invasion. What effect did the zebra mussels have on the phytoplankton in the Hudson River?
A. The number of phytoplankton in the river rose by a little.
B. The number of phytoplankton in the river fell by a little.
C. The number of phytoplankton in the river rose by a lot.
D. The number of phytoplankton in the river fell by a lot.
Answer:
D The number of phytoplankton in the river fell by a lot.
Explanation:
Phytoplankton are an important part of the aquatic food web because they are the primary producers of food for zooplankton and foraging fish. ... When zebra mussels are introduced into a waterbody such as Seneca Lake they can impact this food web by competing for food with other organisms that depend on the phytoplankton.
Among all the given options, the correct option is option D. The number of phytoplankton in the river fell by a lot.
What is Phytoplankton?We may define phytoplankton as a sort of autotrophic (self-feeding) plankton which can be found in both freshwater and marine environments.
Photosynthesis is the process through which phytoplankton, such as trees as well as other land plants, obtain energy. This suggests that because phytoplankton depends on sunlight to exist, they are found in the upper layers of lakes and seas (euphotic zone).
According to the definition of phytoplankton, it is spread across a larger surface area than terrestrial plants, is susceptible to less seasonal change, and has significantly faster turnover rates that trees (days versus decades).
Therefore, the correct option is option D.
