The concentration of the H2SO4 solution is 0.080 M.

The concentration of 50.0 ml of a solution of H2SO4 can be found by titrating the acid with a standardized solution of Ba(OH)2. This can be achieved by first preparing a 0.20M solution of Ba(OH)2 by dissolving a known mass of the reagent in distilled water and diluting to the mark. The end point is reached when all the H2SO4 has reacted with Ba(OH)2 and no more acid is left to react with the reagent.When 40.0 ml of 0.20M Ba(OH)2 titrant was added, we can calculate the amount of moles of Ba(OH)2 that reacted with the H2SO4 and use this value to find the concentration of H2SO4. To do this, we can use the following balanced equation:H2SO4 + 2Ba(OH)2 → BaSO4 + 2H2OFrom the balanced equation, we can see that one mole of H2SO4 reacts with two moles of Ba(OH)2. Thus, the number of moles of Ba(OH)2 used in the titration is given by:(40.0/1000) L × (0.20 mol/L) = 0.008 molWe can use the number of moles of Ba(OH)2 used to calculate the number of moles of H2SO4 present in the original solution. Since one mole of H2SO4 reacts with two moles of Ba(OH)2, the number of moles of H2SO4 in the solution is given by:0.008 mol Ba(OH)2 × (1 mol H2SO4 / 2 mol Ba(OH)2) = 0.004 mol H2SO4.The concentration of H2SO4 is then given by dividing the number of moles of H2SO4 by the volume of the solution in liters:0.004 mol / (50.0/1000) L = 0.080 M.

Answer:

The answer is "the ball has both kinetic and potential energy at C"

Explanation:

It was correct on the test

Answer: If a hydrogen atom and a helium atom have the same kinetic energy then the wavelength of the hydrogen atom will be roughly equal to the wavelength of the helium atom.

Explanation:

The relation between energy and wavelength is as follows.

\(E = \frac{hc}{\lambda}\\\)

This means that energy is inversely proportional to wavelength.

As it is given that energy of a hydrogen atom and a helium atom is same.

Let us assume that \(E_{hydrogen} = E_{helium} = E'\). Hence, relation between their wavelengths will be calculated as follows.

\(E_{hydrogen} = \frac{hc}{\lambda_{hydrogen}}\)    ... (1)

\(E_{helium} = \frac{hc}{\lambda_{helium}}\)         ... (2)

Equating the equations (1) and (2) as follows.

\(E_{hydrogen} = E_{helium} = E'\\\frac{hc}{\lambda_{hydrogen}} = \frac{hc}{\lambda_{helium}} = E'\\\lambda_{helium} = \lambda_{hydrogen} = E'\)

Thus, we can conclude that if a hydrogen atom and a helium atom have the same kinetic energy then the wavelength of the hydrogen atom will be roughly equal to the wavelength of the helium atom.

The concentration of the HNO₃ solution needed to neutralize the 27.60 mL of 1.00 M NaOH is 2.76 M

The balanced equtaion is given below:

HNO₃ + NaOH —> H₂O + NaNO₃

Now, we shall obtain the concentration of the HNO₃ solution needed for the neutralization reaction. This is shown below:

CaVa / CbVb = nA / nB

(Ca × 10) / (1 × 27.6) = 1

(Ca × 10) / 27.6 = 1

Cross multiply

Ca × 10 = 27.6

Divide both side by 10

Ca = 27.6 / 10

Ca = 2.76 M

Thus, the concentration of the HNO₃ solution needed is 2.76 M

Answer:

A dot drawn at the center of the circle represents the front C.

A circle is used to represent the back carbon.

There will be 3 lines drawn directly to each C atom.

Explanation:

A Newman projection is an alternative way to view a molecule instead of the sawhorse projection.

In a Newman projection, the front atom is shown as a dot at the center of a big circle while the back atom is shown as a circle. Three lines indicating binds to substituents are drawn to each carbon atom directly.

This method of representation of molecules was introduced by Melvin Spencer Newman in 1952 to partly replace Fischer projections. Fischer projections did not adequately show the conformer of a compound.

Answer:

53.5gram.

Explanation

Explanation: number of moles = number of molecule ÷ avogadro's number. => moles = 6.022 × 10²³ ÷ 6.022 × 10²³ = 1 mole. mass of 1 mole of NH4Cl = 1 × molar mass.

The concentration of sodium acetate (NaC₂H₃O₂) in the buffer solution is: 0.029 M.

A buffer solution is a solution that is resistant to changes in pH when small amounts of an acid or a base are added to it. It is able to do this because it contains both a weak acid and its conjugate base (or a weak base and its conjugate acid).

To determine the concentration of sodium acetate (NaC₂HO₂) in the buffer solution, you can use the Henderson-Hasselbalch equation:

pH = pKa + log([C₂H₃O₂-]/[HC₂H₃O₂])

where [C₂H₃O₂-] is the concentration of the acetate ion (the conjugate base of acetic acid) and [HC₂H₃O₂] is the concentration of acetic acid.

So, Plugging in the given values, we get:

4.31 = -log(1.8 x 10^-5) + log([C₂H₃O₂-]/1.0)

Solving for [C₂H₃O₂-] above, we see that it is = 0.029 M.

Since the concentration of sodium acetate is equal to the concentration of acetate ions, the concentration of sodium acetate in the buffer solution is also 0.029 M.

Explanation:

Gravitational pull is stronger when the person is closer to the planet.

The gravitational force is the fundamental force of the universe. Here the astronaut at position B will experience a stronger gravitational pull as compared to the astronaut at position A.

The gravitational force is defined as the force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of the distance among them.

F = G m₁m₂ / r²

The gravitational force decreases with the increase in the distance. So here distance of astronaut at position B which is closer to the planet experience greater gravitational pull.
