Answer:
The sample which would contain more oxygen atoms is a glass stirring rod.
Explanation:
According to the periodic table ,
the glass stirring rod is Silicon dioxide and the cotton ball is cellulose
Here , the molar mass of the glass stirring rod \(SiO_{2}\) = 60.08 Grams/mole
Molar mass of the cotton ball \(C_{6} H_{10}O_{5}\) = 162.09 gram/mole .
since ,total number of molecules present in oxygen is 32 ,
therefore ,
In glass stirring rod ,
number of oxygen atoms present in 5g = \(\frac{32}{60.07} \times 5\)
= 2.66 g of oxygen
\(\frac{1}{16} \times 2.66\)
= 0.16625 moles
= 0.16625 x \(6.023\times 10^{23}\)
=\(1.001 \times10^{23}\) atoms
In cotton ball ,
number of oxygen atoms present in 5g = \(\frac{80}{162.09} \times 5\)
= 2.467 g of oxygen
\(\frac{1}{16} \times 2.467\)
= 0.15418 moles
= 0.15418 \(\times 6.023 \times 10^{23}\)
= 0.928 \(\\ \times10^{23}\)
Hence , the glass stirring rod contains more number of oxygen atoms .

The plot of a substance's absorbance as a function of light wavelength is called the absorbance spectrum. The absorbance spectrum in this instance is for the nickel(II) ion.
The peak in absorbance shows that the nickel(II) ion's electrons are most easily moved from a lower energy state to a higher energy one by this particular wavelength of light. As a result, more light is absorbed, increasing the measured absorbance.
Depending on the particular experiment and the tools being used, a specific wavelength of light should be employed. However, judging by the absorbance spectrum displayed, measuring nickel(II) ion absorbance should be possible at a wavelength of roughly 400–500 nm.

Sometimes a simple incident in our lives can actually have a deeper meaning and impact on us than might be apparent at the time. Write a reflective narrative about a memorable experience in your life.
Answers
I remember the day when I was walking to the grocery store and saw an elderly woman sitting on the sidewalk with her cart. She looked tired and was trying to catch her breath. At first, I walked past her, not wanting to get involved. But then something made me stop and turn around. I approached her and asked if she needed any help. She told me that she had been walking for a while and needed to rest for a bit. I helped her sit down on a nearby bench, and we started talking.
As we talked, I learned that her name was Mary, and she had lived in the neighborhood for over 50 years. She shared stories of her life and her struggles, and I listened with empathy. I could see the gratitude in her eyes, and it made me realize the power of human connection.
That experience taught me that we should never underestimate the impact of a simple act of kindness. It made me more aware of the people around me and more willing to help others in need. It also showed me the importance of empathy and how it can make a difference in someone's life.
Looking back, that moment was a turning point for me. It made me more compassionate and more aware of the needs of others. It showedme that a small gesture of kindness can have a ripple effect and make a big difference in someone's life. It also reminded me that we all have our own stories and struggles, and sometimes all we need is someone to listen and show us a little empathy.
Since that day, I have made it a point to be more aware of the people around me and to offer help whenever I can. Whether it's holding the door open for someone or offering a listening ear, I try to be more present and empathetic in my interactions with others.
That experience also taught me the importance of slowing down and taking the time to connect with people. In our fast-paced world, it's easy to get caught up in our own lives and forget about those around us. But by taking the time to connect with others, we can create meaningful relationships and make a positive impact in the world.
Overall, that simple encounter with Mary taught me a valuable lesson about the power of empathy and human connection. It's a lesson that I will always carry with me and strive to live by in my daily life.

A balloon under 1 atm of pressure contains 10.0 g of neon gas. With the temperature kept constant, 15.0 g of xenon gas is added. What happens?
Answers
Answer:
The volume of the ballon expands 1.2 times
Explanation:
The pressure in the ballon will be always the same. And as temperature is also the same the only parameters that change are moles of gas and volume.
The volume is directely proportional to moles of the gas under pressure and temperature constant (Avogadro's law). That means:
V₁ / n₁ = V₂ / n₂
Where V is volume and n moles of 1, initial statet and 2, final state of the gas
Initial moles of Neon gas (20g/mol) are:
10.0* (1mol / 20g) = 0.5 moles are equal to initial moles that occupies X liters of volume.
As you add 15.0g of Xe (Molar mass: 131g/mol):
15.0g * (1mol / 131g) = 0.11 moles + 0.55 moles = 0.66 moles that are final moles.
Replacing in Avogadro's law:
V₁ / n₁ = V₂ / n₂
X L / 0.55moles = V₂ / 0.66 moles
1.2X L = V₂
That means the volume of the ballon expands 1.2 times

Gaseous butane (CH3(CH2)2CH3) will react with gaseous oxygen (02) to produce carbon dioxide (CO2) and gaseous water (H2O). Suppose 34.g of butane s mixed with 200. g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.
Answers
The maximum mass of water that can be produced by the reaction is 43.3 g, rounded to three significant figures.
Determining the maximum mass of water producedThe balanced chemical equation for the reaction between butane and oxygen is:
C4H10 + 13/2 O2 → 4 CO2 + 5 H2O
From the equation, we can see that 1 mole of butane reacts with 13/2 moles of oxygen to produce 5 moles of water.
moles of butane = 34. g / 58.12 g/mol = 0.585 mol
moles of oxygen = 200. g / 32.00 g/mol = 6.25 mol
Determining the limiting reactant.
butane : oxygen = 0.585 mol : 6.25 mol
= 0.0936 : 1.00
stoichiometric ratio = 1 : 13/2
= 0.7692 : 1.00
Since the actual ratio is lower than the stoichiometric ratio for oxygen, it is the limiting reactant.
The maximum amount of water that can be produced is determined by the amount of limiting reactant (oxygen).
moles of water = 5/13 * 6.25 mol
= 2.403 mol
Finally, we can convert the moles of water to grams:
mass of water = 2.403 mol * 18.015 g/mol
= 43.3 g

positive protons are the cores of atoms in relative to electrons very, very heavy.
the outer electrons of atoms can move, under certain conditions, away from the atom, leaving it electrically unbalanced -> positively charged
there can also be a surplus of electrons on many surfaces, leading to a static negative charge. you know this when you are charged and you discharge with an object or another person, electrically balancing the two bodies charge.
electrons are also much smaller. they are the "things" to move, let it be trough the air or trough a wire, while the heavy protons will stay in place (unless the materials is melted of course, extreme heat brakes the bounds between atoms relatively well)

A 13.0 ml sample of an acid requires 37,3 ml of 0.303N NaOH for neutralization. Calculate the normality of the acid.
Answers
The amount of 0.303N NaOH needed to neutralize a 13.0 ml sample of acid is 37,3 ml. Acid is 0.823N normal, according to the standard.
Explain about the neutralization.The idea of neutralization, according to which an acid reacts with a base to create salt and water. By comparing the molarity of the base to the amount of base needed for neutralization, it is possible to calculate the molarity of the acid. Once the molarity and the acid's valence (or charge) have been multiplied, the acid's normalcy can be determined.
By deducting the volume of NaOH (37.3 ml) from the volume of the acid sample in Step 1, you can calculate the amount of acid that was utilized in the neutralization procedure (13.0 ml).
Consequently, 13.0 ml to 37.3 ml
= -24.3 ml
Use the equation moles = normality x volume to determine the number of moles of acid that were used in the process.
Consequently, moles equal 0.303N x -24.3 ml.
= -7.33 moles
Determine the acid's normality by multiplying the volume by the formula normalcy = moles.
As a result: normalcy = -7.33 moles / 13.0 ml
= -0.823N
