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:

SRB (sulfate reducing bacteria)
A) descrease the corrosion of metal pipe in clay environments
B) decrease the corrosion in all environments
C) accelerate corrosion of metal pipe in clay environments
The SRB (sulfate-reducing bacteria) is a type of bacteria that can reduce sulfate to sulfide. These bacteria can have an impact on the corrosion of metal pipes in various environments. Among the given options C) Accelerate corrosion of metal pipe in clay environments.
The SRB can accelerate the corrosion of metal pipes in clay environments. In these environments, the bacteria produce sulfide, which reacts with the metal surface, forming metal sulfides. This process leads to a localized breakdown of the protective film on the metal surface, exposing the underlying metal to further corrosion. Clay environments provide a suitable habitat for SRB, as they offer the necessary nutrients and anaerobic conditions that these bacteria require to thrive. Consequently, the presence of SRB in clay environments can increase the rate of corrosion of metal pipes, leading to potential failure and the need for costly repairs or replacement.

compare the size of ions to the size of atoms from which they form
Cations are always smaller than the atoms from which they form. Anions are always larger than the atoms from which they form. Ions are usually bigger than the atoms from which they are formed.
When an atom receives or loses electrons, the atom's electron configuration changes, resulting in a net positive or negative charge.
This net charge expands the electron cloud surrounding the nucleus, making the ion bigger in size than the neutral atoms from which it arose. When a metal atom loses one or more electrons to create a cation, it shrinks in size because the positive charge of the nucleus pulls the remaining electrons more strongly.
When a nonmetal atom obtains one or more electrons to create an anion, it normally expands in size.Because of the increasing amount of electrons, the electron cloud surrounding the nucleus grows. It should be noted that this comparison is not absolute and is dependent on the individual factors involved. Some ions are smaller than their neutral atom counterparts, while others are similar in size.

A 54.8 g sample of quartz, which has a specific heat capacity of 0.730 J-g¹C¹, is put into a calorimeter (see sketch at right)
that contains 200.0 g of water. The temperature of the water starts off at 23.0 °C. When the temperature of the water stops
changing it's 26.4 °C. The pressure remains constant at 1 atm.
Calculate the initial temperature of the quartz sample. Be sure your answer is rounded to 2 significant digits.
Answer:
The initial temperature of the quartz sample was 16.3 °C.
Explanation:
The heat lost by the quartz sample is equal to the heat gained by the water and the calorimeter. Therefore:
q_quartz = q_water + q_calorimeter
The heat lost by the quartz sample can be calculated using the equation:
q_quartz = m_quartz × c_quartz × ΔT_quartz
where m_quartz is the mass of the quartz sample, c_quartz is the specific heat capacity of quartz, and ΔT_quartz is the change in temperature of the quartz sample.
The heat gained by the water and calorimeter can be calculated using the equation:
q_water + q_calorimeter = (m_water + m_calorimeter) × c_water × ΔT_water
where m_water is the mass of the water, m_calorimeter is the mass of the calorimeter, c_water is the specific heat capacity of water, and ΔT_water is the change in temperature of the water and calorimeter.
Since the pressure is constant and no work is being done, we can assume that the total heat gained by the water and calorimeter is equal to the heat lost by the quartz sample. Therefore:
m_quartz × c_quartz × ΔT_quartz = (m_water + m_calorimeter) × c_water × ΔT_water
Substituting the given values, we get:
(0.0548 g) × (0.730 J/g·°C) × (T_i - 26.4 °C) = (200.0 g + 100.0 g) × (4.184 J/g·°C) × (26.4 °C - 23.0 °C)
Simplifying and solving for Ti, we get:
Ti = 16.3 °C (rounded to 2 significant digits)
Therefore, the initial temperature of the quartz sample was 16.3 °C.
g Explain the effect of concentration on reaction rate in terms of collision theory. Your answer should include at least four complete sentences.
The effect of concentration on reaction rate in terms of collision theory is that an increase in concentration leads to an increased reaction rate.
This is because the likelihood of reactant particles colliding and reacting increases as the concentration of reactants increases. There are more reactant particles in a given volume, the frequency of collisions between them also increases. This results in a higher rate of successful collisions, which leads to a faster reaction rate.
This is because, with a higher concentration of reactants, there are more particles available to collide with one another. As a result, the frequency of collisions between reactant particles increases, which ultimately leads to a higher rate of successful collisions and a faster reaction rate. In summary, the concentration of reactants has a direct impact on reaction rate due to its influence on the number of collisions occurring between particles.

with the balanced equation : 4Fe + 3O2 = 2Fe2O3How many grams of Fe2O3 is produced when you start with 0.89 moles of iron?
Answer:
72.66g of Fe2O3 are produced.
Explanation:
1st) From the balanced equation we know that 2 moles of Fe2O3 are produced from 4 moles of iron (Fe). With a mathematical rule of three we can calculate the moles of Fe2O3 that will be produced from 0.89 moles of iron:
\(\begin{gathered} 4molesFe-2molesFe_2O_3 \\ 0.89molesFe-x=\frac{0.89molesFe*2molesFe_2O_3}{4molesFe} \\ x=0.445molesFe_2O_3 \end{gathered}\)Now we know that 0.455 moles of Fe2O3 are produced.
2nd) Now we have to convert 0.455 moles of Fe2O3 into grams, by using the molar mass of Fe2O3 (159.7g/mol):
\(0.455moles*\frac{159.7g}{1mole}=72.66g\)So, 72.66g of Fe2O3 are produced.

Examples of atoms that behave similar to chlorine interms of afinity
Answer: Here are some examples of atoms that behave similarly to chlorine in terms of electron affinity:
Fluorine (F) has the highest electron affinity of any element, so it is more electronegative than chlorine. However, fluorine and chlorine are both halogens, which means that they have similar chemical properties.
Bromine (Br) is also a halogen, and it has a very similar electron affinity to chlorine. In fact, bromine is often used as a substitute for chlorine in organic chemistry.
Iodine (I) is the third halogen, and it has a slightly lower electron affinity than chlorine. However, iodine is still a very electronegative element, and it behaves similarly to chlorine in many chemical reactions.
Nitrogen (N) is not a halogen, but it has a relatively high electron affinity. This is because nitrogen has a small atomic radius, which means that its valence electrons are held more loosely than the valence electrons of larger atoms.
Oxygen (O) is also not a halogen, but it has a relatively high electron affinity. This is because oxygen has a small atomic radius and it also has two unpaired valence electrons.
Explanation: Fluorine has the highest electron affinity, followed by chlorine, bromine, and iodine.
Nitrogen and oxygen also have high electron affinities because they have small atomic radii and unpaired valence electrons.
Atoms with high electron affinity are more likely to attract electrons, which means they are more electronegative.

A 175 gram sample of a metal at 93.50c was added to 105 grams of water at 23.50c in a perfectly insulated container. the final temperature of the water and metal was 33.80c. calculate the specific heat of the metal in j/g0c.
The specific heat of the metal is 0.214 J/g°C.
When a metal and water are mixed in a perfectly insulated container, they reach a final temperature through heat transfer. In this case, the initial temperature of the metal is 93.50°C, while the initial temperature of the water is 23.50°C. The final temperature of the mixture is 33.80°C.
To calculate the specific heat of the metal, we can use the principle of conservation of energy. The heat lost by the metal (Qmetal) is equal to the heat gained by the water (Qwater). The formula for heat transfer is:
Q = m * c * ΔT
Where:
Q is the heat transferred
m is the mass of the substance
c is the specific heat
ΔT is the change in temperature
Let's denote the specific heat of the metal as cm and the specific heat of water as cw. The heat lost by the metal can be calculated as:
Qmetal = cm * mmetal * (Tfinal - Tinitial_metal)
The heat gained by the water can be calculated as:
Qwater = cw * mwater * (Tfinal - Tinitial_water)
Since the container is perfectly insulated, the heat lost by the metal is equal to the heat gained by the water:
Qmetal = Qwater
cm * mmetal * (Tfinal - Tinitial_metal) = cw * mwater * (Tfinal - Tinitial_water)
Rearranging the equation, we can solve for the specific heat of the metal:
cm = (cw * mwater * (Tfinal - Tinitial_water)) / (mmetal * (Tfinal - Tinitial_metal))
Substituting the given values:
cm = (4.18 J/g°C * 105 g * (33.80°C - 23.50°C)) / (175 g * (33.80°C - 93.50°C))
After evaluating the expression, the specific heat of the metal is calculated to be approximately 0.214 J/g°C.
