based on the results of experiment 1, if 10 ml of n2 were completely reacted with 40ml of h2 at the same pressure and temperature, what volume of h2 would remain unreacted
Answers
Based on the results of experiment 1, if 10 ml of N2 were completely reacted with 40 ml of H2 at the same pressure and temperature, the volume of H2 that would remain unreacted can be determined using the concept of stoichiometry.
10 ml N2 / 1 * (3/1) = 30 ml H2So, if 10 ml of N2 were completely reacted with 30 ml of H2, then 10 ml of N2 would require 30 ml of H2 to react completely.However, in the given scenario, we have 40 ml of H2, which is more than enough to react with 10 ml of N2. Therefore, no H2 would remain unreacted.
In conclusion, based on the results of experiment 1, if 10 ml of N2 were completely reacted with 40 ml of H2 at the same pressure and temperature, no volume of H2 would remain unreacted.

which atom is least likely to violate the octet rule in its compounds?
Answers
The atom that is least likely to violate the octet rule in its compounds is helium.
The octet rule is a chemical principle that states that atoms tend to bond in such a way as to have eight electrons in their outermost energy level. In other words, atoms want to have a full valence shell, which is why they bond with other atoms. However, some atoms are more likely than others to violate the octet rule. In this case, helium is the atom that is least likely to violate the octet rule in its compounds.
This is because helium has only two electrons in its outermost energy level, so it only needs to gain or lose two electrons in order to have a full valence shell. Other atoms with more than two electrons in their outermost energy level are more likely to violate the octet rule because they need to gain or lose more electrons to have a full valence shell.

Explanation:
A 0.325 g sample of copper was weighed out by a student to start this experiment.
1. How many moles of Cu2+ ions should be produced when the nitric acid was added to the copper metal?
2.When the sodium hydroxide was added to the solution, how many moles of Cu(OH)2 should have formed?
3. The directions require you to add 1.00 g of zinc. If you assume a 100 % yield of copper, how many grams of zinc were added in excess?
4. If magnesium metal were used instead of zinc metal, what is the minimum mass, in grams, of magnesium metal that should be used to ensure that all of the copper ions in the solution is converted back to copper metal?
Answers
When sodium hydroxide was added to the 0.325 g sample of copper, approximately 0.00512 moles of \(CuOH_{2}\) should have formed.
To determine how many moles of \(CuOH_{2}\) should have formed when sodium hydroxide was added to the 0.325 g sample of copper, follow these steps:
Step 1: Find the molar mass of copper (Cu)
The atomic mass of copper is approximately 63.5 g/mol.
Step 2: Calculate the moles of copper (Cu) in the sample
To find the moles of copper in the 0.325 g sample, divide the mass of the sample by the molar mass of copper:
Moles of Cu = mass of Cu / molar mass of Cu
Moles of Cu = 0.325 g / 63.5 g/mol
Moles of Cu ≈ 0.00512 mol
Step 3: Determine the chemical equation for the reaction
The balanced chemical equation for the reaction between copper and sodium hydroxide to form copper hydroxide (\(CuOH_{2}\)) is:
2 \(NaOH\) + Cu → \(CuOH_{2}\) + 2 Na
From the balanced equation, you can see that 1 mole of copper reacts with 2 moles of sodium hydroxide to form 1 mole of copper hydroxide \(CuOH_{2}\).
Step 4: Calculate the moles of \(CuOH_{2}\) formed
Since the ratio between moles of Cu and \(CuOH_{2}\) is 1:1, the moles of \(CuOH_{2}\) formed will be the same as the moles of Cu in the sample:
Moles of \(CuOH_{2}\) = moles of Cu
Moles of \(CuOH_{2}\) ≈ 0.00512 mol
In conclusion, when sodium hydroxide was added to the 0.325 g sample of copper, approximately 0.00512 moles of \(CuOH_{2}\) should have formed.

c
The difference in electronegativity of the two elements is greater than 1.7 but less than 3.0.
d
The difference in electronegativity of the two elements is zero.
Answers
Answer:
B.) The difference in electronegativity of the two elements is less than 1.7.
Explanation:
A difference of less than 2 between atoms leads to covalent bond formation. Electronegativity is the ability of an atom to draw bonding electrons when it is bonded.
We know that in covalent bonding, atoms "share" elections. We also know that in ionic bonding, atoms "take" electrons. If the electronegativity was too great then atoms would no longer share electrons, one would just draw the electron to it. The ideal values to covalently bond, in this case, would be below two.

if , group of answer choices the activation energy will change as the reaction progresses. the forward reaction will have a greater activation energy than the reverse reaction. the forward reaction is slower than the reverse reaction. the collision energy of the reactants will be greater than that of the products. the reaction rate will speed up with time.
Answers
The activation energy refers to the amount of energy required for a chemical reaction to occur. As the reaction progresses, the activation energy can change depending on the specific reaction conditions.
In some cases, the forward reaction may have a greater activation energy than the reverse reaction, which means that it will require more energy to proceed. Additionally, the forward reaction may be slower than the reverse reaction due to the higher activation energy barrier. This is because the collision energy of the reactants will be greater than that of the products, which makes it more difficult for the reaction to proceed in the forward direction.
However, over time, the reaction rate will speed up as more and more reactants collide and overcome the activation energy barrier. This increase in speed will eventually lead to a state of equilibrium where the forward and reverse reactions occur at equal rates. If the collision energy is greater than the activation energy, the reaction rate will speed up with time as more reactant molecules are converted into products.

In the Millikan oil droplet experiment, the oil is sprayed from an atomizer into a chamber. The droplets are allowed to pass through the hole into the chamber so that their fall can be observed. The top and bottom of the chamber consist of electrically charged plates. The upper plate is positively charged, and the lower plate is negatively charged. X rays are introduced into the chamber so that when they strike the oil droplets, the droplets will acquire one or more negative charges. The electric field (voltage) is applied to the metal plates.
Watch the animation and identify the effects of an electric field on the motion of a negatively charged oil droplet. Consider the gravitational force as Fg and the electric force as Fe. All the other forces acting on the oil droplet can be ignored as their effect on the motion of the oil droplet is negligible.
A/ In the absence of an electric field, the oil droplet falls freely due to the gravitational force.
B/ If Fe is increased until it is equal to Fg, the negatively charged oil droplet will remain stationary.
C/ If Fe is greater than Fg, the negatively charged oil droplet will move freely toward the negatively charged plate.
D/ In the presence of an electric field, the negatively charged oil droplet moves freely toward the negatively charged plate.
** I chose B, but that was the wrong answer
Answers
C/ If Fe is greater than Fg, the negatively charged oil droplet will move freely toward the negatively charged plate.
In the Millikan oil droplet experiment, the negatively charged oil droplets are subjected to an electric field created by the charged plates. The electric force (Fe) acts on the oil droplet in a direction opposite to the gravitational force (Fg). When Fe is greater than Fg, the electric force overcomes the gravitational force, causing the negatively charged oil droplet to experience an upward force. As a result, the oil droplet moves freely upward toward the negatively charged plate.
Option B is incorrect because if Fe is equal to Fg, the forces balance each other, resulting in a stationary droplet. However, the question states that Fe is increased until it is greater than Fg, implying that the droplet is no longer stationary but moves in response to the electric force.
Therefore, option C is the correct answer, as it describes the effect of an electric field on the motion of a negatively charged oil droplet in the Millikan oil droplet experiment.

Arrange the following atoms in order from smallest to largest atomic radius: Be, Mg, Ca, and Ba. For Mg and Na, write Mg Na or Mg, Na.
Answers
The order from smallest to largest atomic radius is
Be < Mg < Ca < Ba, For Mg and Na, Mg has a smaller atomic radius than Na, so the correct answer is "Mg, Na".
The atomic radius generally increases down a group and decreases across a period in the periodic table. Going from Be to Ba, we are going down Group 2, which means the atomic radius increases. However, within a period, going from left to right, the atomic radius decreases.
The trend in atomic radius across a period is primarily due to increasing nuclear charge as you move from left to right, which attracts the electrons in the outermost energy level closer to the nucleus. This results in a smaller atomic radius.
On the other hand, down a group, the number of energy levels or electron shells increases, which shields the outermost electrons from the attractive force of the nucleus. As a result, the electrons can occupy energy levels farther from the nucleus, leading to an increase in atomic radius.

How many molecules of H2S are required to form 79.0 g of sulfuraccording to the following reaction? Assume excess SO2. 2 H2S(g) + SO2(g) ? 3 S(s) + 2H2O(l)Answer 9.89 × 1023 molecules H2S 5.06 × 1025 molecules H2S 2.44 ×1023 molecules H2S 1.48 × 1024 molecules H2S3.17 × 1025molecules H2S
Answers
About 9.89 × 10²³ molecules of H₂S are required to form 79.0 g of sulfur. The correct answer is 9.89 × 10²³ molecules H₂S.
To determine the number of molecules of H₂S required to form 79.0 g of sulfur, we need to use stoichiometry and the molar mass of sulfur.
The molar mass of sulfur (S) is approximately 32.07 g/mol.
First, calculate the number of moles of sulfur in 79.0 g:
moles of sulfur = mass of sulfur / molar mass of sulfur
moles of sulfur = 79.0 g / 32.07 g/mol
moles of sulfur ≈ 2.46 mol
According to the balanced equation, the stoichiometric ratio between H₂S and S is 2:3. This means that for every 2 moles of H₂S, we obtain 3 moles of S.
Now, we can set up a proportion to find the number of moles of H₂S:
2 moles H₂S / 3 moles S = x moles H₂S / 2.46 moles S
Solving for x gives us the number of moles of H₂S needed:
x = (2 moles H₂S / 3 moles S) * 2.46 moles S
x ≈ 1.64 mol H₂S
Finally, to convert moles to molecules, we use Avogadro's number:
1 mol H₂S ≈ 6.022 × 10²³ molecules H₂S
Number of molecules of H₂S = 1.64 mol H₂S * (6.022 × 10²³ molecules H₂S/mol)
Number of molecules of H₂S ≈ 9.89 × 10²³ molecules H₂S
Therefore, the correct answer is 9.89 × 10²³ molecules H₂S.
