Larissa is making sautéed purple cabbage. First, she washes and cuts the cabbage into long thin strands. Then, she puts a
pan on the stove and adds butter. She allows the butter to melt and turn to liquid. Next, she adds the cabbage to the butter
sprinkles some salt on it, and stirs it. Larissa watches as the cabbage sizzles, releases steam, and softens. To finish the side
dish, she adds a squeeze of lemon juice to it, which causes it to change from purple to pink. Finally, Larissa empties the
cabbage into a bowl and puts it on the dinner table.

Answer: The volume of [tex]NaOH[/tex] required is 25.0 ml

Explanation:

According to the neutralization law,

[tex]n_1M_1V_1=n_2M_2V_2[/tex]

where,

[tex]n_1[/tex] = basicity [tex]HNO_3[/tex] = 1

[tex]M_1[/tex] = molarity of [tex]HNO_3[/tex] solution = 2.00 M

[tex]V_1[/tex] = volume of  [tex]HNO_3[/tex] solution = 50.0 ml

[tex]n_2[/tex] = acidity of [tex]NaOH[/tex] = 1

[tex]M_1[/tex] = molarity of [tex]NaOH[/tex] solution = 4.00 M

[tex]V_1[/tex] = volume of  [tex]NaOH[/tex] solution =  ?

Putting in the values we get:

[tex]1\times 2.00\times 50.0=1\times 4.00\times V_2[/tex]

[tex]V_2=25.0ml[/tex]

Therefore, volume of [tex]NaOH[/tex] required is 25.0 ml

The volume of 4.00 M NaOH is required to exactly neutralize 50.0 ml of a solution of a 2.00 M solution of [tex]HNO_3[/tex] is 25.0 ml.

[tex]HNO_3[/tex] is nitric acid also known as the spirit of niter. It is colorless in its original form but appears yellow-colored.

By the neutralization law

[tex]n_1M_1V_1 = n_2M_2V_2[/tex]

n1 = 1

M1 = 2.00

M2 = 4.00

V1 = 50.0 ml

n2 = NaOH = 1

Putting the value in the formula

[tex]1 \times 2.00 \times 5.00 ml = 1 \times 4.00 \times V_2\\\\V_2 = 25.0\; ml[/tex]

Thus, the volume of NaOH required is 25.0 ml.

Answer:

Las cargas eléctricas de los objetos son ambas positivas o son ambas negativas.

Explanation:

Si dos objetos presentan fuerzas eléctricas repulsivas entre sí, quiere decir que ambos tienen el mismo tipo de carga.

Las cargas iguales (positivo con positivo, o negativo con negativo) se repelen, mientras que las cargas diferentes (positivo con negativo) se atraen.

Answer:

Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.

The carbon-hydrogen bond (C–H bond) is a bond between carbon and hydrogen atoms that can be found in many organic compounds. This bond is a covalent bond meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells making them stable.

Explanation:

Concentration question....

0.965L x (0.0575 mol MgSO4 / 1L) x (120.4g MgSO4 / 1 mol MgSO4) = 6.68g MgSO4

The concept molarity is used here to determine the grams of magnesium sulfate dissolved in 0.965 L of a 0.0575 M solution. The mass of magnesium sulfate in grams is 6.68 g.

The molarity of a solution is defined as the number of moles of the solute present per litre of the solution. It is generally represented by the unit mol/L. The equation used to calculate the molarity is:

Molarity = Number of moles of the solute / Volume of the solution in litres

The molar mass of MgSO₄ = 120.36 g/mol

We have 0.0575 M solution.

That is 0.0575 mol/L × 120.36 g/mol = 6.9207 g/L

Here we want mass in 0.965 L. So the mass is:

Mass = 0.965 L × 6.9207 g/L = 6.68 g

Thus the mass in grams of magnesium sulfate is 6.68 g.

Speed has a greater impact on mass because its increases in velocity have an exponentially greater impact on translational kinetic energy because kinetic energy is proportional to velocity squared. Doubling an object's mass would only double its kinetic energy, however doubling its momentum would quadruple its velocity.

The moles of gas at the given sample of gas is 1.7 moles.

Ideal gas equation gives idea about the behavior of gas at different condition & represented as:

PV = nRT, where

On putting all these values, we get moles as:

n = (1.2)(31) / (0.082)(256) = 37.2 / 20.9

n = 1.7 moles

Hence required moles of gas is 1.7 mole.
