Answer:
see explanation
Explanation:
If we look at the structures of each of the compounds we can be able to deduce the accurate hybridization of each of the atoms listed.
Looking at ClNO - we can see that the nitrogen atom is linked to oxygen by a double bond and linked to chlorine by a single bond retaining a lone pair on nitrogen. Hence the nitrogen is in sp2 hybridized state.
For ClOCl, the compound has a sp3 hybridized oxygen atom linked to two chlorine atoms as expected retaining two lone pairs on oxygen.
For NCOH, the carbon atom is doubly bonded to oxygen hence it is sp2 hybridized.
Answer:
A) Label 2 (Sp2)
B) Label 3 (Sp3)
C) Label 1 (Sp)
Explanation:
A) Have 7 Lone Pairs (LP) to place. 1 on N. 1 becomes a double bond. Double bonds count as 1 Electron Group. Same for single bond and LP. Add these to get 3. 3 coresponds for SP2
B) 8LP. 2LP on O. 2 bonds to O. Add to get 4. 4-> Sp3
C) 5LP. C O bond is double. single bond to N. Add to get 2-> Sp

What is the mass % of acetone in a 1.77 M solution of acetone (MM = 58.08 g/mol) in water? The density of the solution is 0.971 g/mL.
Answer:
[tex]\%m/m=10.6\%[/tex]
Explanation:
Hello!
In this case, since the by-mass percent is defined by:
[tex]\%m/m=\frac{m_{solute}}{m_{solution}} *100\%[/tex]
Thus, since the given 1.77 M solution is given in terms of mol/L, we need to compute the mass of acetone via its molar mass and the volume of solution in L to g via the density:
[tex]\%m/m=1.77\frac{mol}{L}*\frac{58.08g}{1mol}*\frac{1L}{1000mL}*\frac{1mL}{0.971g} *100\%\\\\\%m/m=10.6\%[/tex]

5.00 ml of an H2SO4 solution with unknown molarity was diluted with 25.00 ml. This was tirated with 15.00ml of .1000 M NaOH to reach the equivalence point. What is the molarity of the original unknown H2SO4 solution? Also, what would the balanced chemical equation for this reaction be?
Answer:
0.1500 M
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O
Explanation:
The balanced chemical equation is:
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂OFirst we calculate how many NaOH moles reacted, using the volume and concentration:
15.00 mL * 0.100 M = 1.5 mmol NaOHThen we convert NaOH moles into H₂SO₄ moles:
1.5 mmol NaOH * [tex]\frac{1mmolH_2SO_4}{2mmolNaOH}[/tex] = 0.75 mmol H₂SO₄This amount of H₂SO₄ moles was originally contained within 5.00 mL of solution, thus the molarity is:
0.75 mmol H₂SO₄ / 5.00 mL = 0.1500 M6. If you 5.5 mol of Nitrogen in: N2 + 3H2 → 2NH3

Two waves were analyzed with some high-tech instrumentation. The first wave was found to have a wavelength of 3 x 10 m and the second wave had a wavelength of 3 x 10 m. Which wave would have a higher frequency? Explain
Explanation:
The first wave was found to have a wavelength of 3 x 10⁵ m and the second wave had a wavelength of 3 x 10⁴ m
We need to find which wave have a higher frequency.
The relation between frequency and wavelength is given by :
[tex]c=f\lambda[/tex]
Let f₁ and f₂ be the frequency of wave 1 and wave 2.
[tex]f_1=\dfrac{c}{\lambda_1}\\\\f_1=\dfrac{3\times 10^8}{3\times 10^5}\\\\=1000\ Hz[/tex]
And
[tex]f_2=\dfrac{c}{\lambda_2}\\\\f_2=\dfrac{3\times 10^8}{3\times 10^4}\\\\=10000\ Hz[/tex]
Hence, the wave having less wavelength will have higher frequency. The wave having wavelength 3 x 10⁴ m will have higher frequency.

b. Ag(s) and Cu(s)
c. Fe2+(aq) and Al3+(aq)
d. Fe(s) and Al(s)
e. Cu2+(aq) and Fe2+(aq)
d. Fe(s) and Al(s)
Further explanationIn the redox reaction, it is also known
Reducing agents are substances that experience oxidation
Oxidizing agents are substances that experience reduction
The metal activity series is expressed in voltaic series
Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-Fe-Cd-Co-Ni-Sn-Pb- (H) -Cu-Hg-Ag-Pt-Au
The more to the left, the metal is more reactive (easily release electrons) and the stronger reducing agent
The more to the right, the metal is less reactive (harder to release electrons) and the stronger oxidizing agent
So that the metal located on the left can push the metal on the right in the redox reaction
The electrodes which are easier to reduce than hydrogen (H), have E cells = +
The electrodes which are easier to oxidize than hydrogen have a sign E cell = -
So the above metals or metal ions will reduce Pb²⁺ (aq) will be located to the left of the Pb in the voltaic series or which have a more negative E cell value (greater reduction power)
The metal : d. Fe(s) and Al(s)

how many moles of atoms of each element in one mole (NH4)2CO3
Answer:
Chemists generally use the mole as the unit for the number of atoms or molecules of a material. One mole (abbreviated mol) is equal to 6.022×1023 molecular entities (Avogadro's number), and each element has a different molar mass depending on the weight of 6.022×1023 of its atoms (1 mole).\

Which answer best describes the reducing and oxidizing processes in this reaction?
NO and CO are both reducing agents.
NO and CO are both oxidizing agents.
The oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds.
The oxidation state of nitrogen in NO changes from 0 to +2, and the oxidation state of carbon in CO changes from +4 to +2 as the reaction proceeds.
Answer:
The oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds.
Explanation:
In the catalytic converter, the oxidation number of nitrogen in NO changes from +2 to 0, and of carbon in CO changes from +2 to +4 as the reaction proceeds. Thus, option C is correct.
What is a catalytic converter?The catalytic converter is a device used in vehicle exhaust to reduce the emission of toxic gas. The reaction in the device occurs to convert the nitric oxide into oxygen and nitrogen.
The redox reaction is given as,
2NO(g) + 2CO(g) → N₂(g) + 2CO₂(g)
In the reduction half of the reaction, the electrons are lost (addition of oxygen) like in carbon monoxide the oxygen is added that changes the number from +2 to +4. CO is a reducing agent that oxidized the carbon atom.
In the reduction half of the reaction, the oxygen is removed (electrons are added) and is shown by NO where the oxygen was lost to form N₂ with oxidation +2 to 0.
Therefore, option C. NO is a reducing agent that reduced nitrogen in the reaction.

What is the correct energy transformation in a hydropower dam?
well
(Sorry for the bad Quality it’s the Computer) PLEASE HELP MEEEE
Answer:
Gravitational to Mechanical to electrical
Explanation:
In a hydropower dam, the gravitational potential energy is converted to mechanical energy which in turn produces electrical energy.
The gravitational potential energy is due to the water overhead and the position of water inside the dam. The height and quantity of water determines the magnitude of the gravitational potential energy. Then, this energy is released when it falls on turbines and it drives them. As the turbine moves, mechanical energy is produced. The turbine is connected through a dynamo which produces a electric current by the turning action.
