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:

[tex]\boxed {\boxed {\sf 3. \ H-H}}[/tex]

Explanation:

To determine the polarity of a bond, we use the electronegativities of the individual atoms. The greater the difference, the more polar the bond.

1. H-Br

3.0-2.2=0.8

2. H-F

4.0-2.2=1.8

3. H-H

2.2-2.2=0.0

4. H-O

3.4-2.2=1.2

As we can see, the lowest difference is in hydrogen hydrogen at 0.0. You may also recognize that because they are 2 atoms of the same element, the electronegativity is the same for both, so it will equal 0. Since the electronegativity is 0, this is a nonpolar bond.

Answer:

The energy of the wave particle is 3.058 x 10⁻²³ J.

Explanation:

Given;

wavelength of the wave particle, λ = 6.5 x 10⁶ nm = (6.5 x 10⁶) x 10⁻⁹ m

The energy of the wave particle is calculated as;

[tex]E = hf\\\\E = \frac{hc}{\lambda}[/tex]

where;

h is Planck's constant = 6.626 x 10⁻³⁴ J/Hz

c is speed of light = 3 x 10⁸ m/s

[tex]E = \frac{(6.626 \times 10^{-34})(3\times 10^8)}{6.5 \times 10^6 \times 10^{-9}} \\\\E = 3.058 \times 10^{-23} \ J[/tex]

Therefore, the energy of the wave particle is 3.058 x 10⁻²³ J.

Answer:

45 mL

Explanation:

Tenemos los siguientes datos:

V = 1 L

C = 4,5% v/v

El porcentaje en volumen (%v/v) expresa el volumen de soluto (alcohol en este caso) que hay cada 100 mL de solución. Si la solución tiene una concentración del 4,5% v/v eso quiere decir que hay 4,5 ml de alcohol cada 100 ml de solución, de acuerdo a lo siguiente:

4,5% v/v alcohol = volumen alcohol/ volumen solución x 100 = 4,5 mL alcohol/100 mL solución= 4,5 mL alcohol/0,1 L alcohol

Por lo tanto, al multiplicar por el volumen total de la solución (1 L), obtenemos la cantidad total de alcohol:

4,5 mL alcohol/0,1 L alcohol x 1 L = 45 mL

answer B

Answer:

X5Y2

Explanation:

% composition of X = 52.2%

% composition of Y = (100 - 52.2) = 47.8%

This means that there are 52.2g of X and 47.8g of Y in the compound

To calculate the empirical formula of the compound, we first convert the gram value to mole value by dividing by their molar masses.

X = 52.2g/42.3g/mol = 1.234mol

Y = 47.8g/96.7g/mol = 0.494mol

Next, we divide each mole value by the smallest value (0.494mol)

X = 1.234mol ÷ 0.494mol = 2.49

Y = 0.494mol ÷ 0.494mol = 1

We multiply each value by 2

X = 2.49 × 2 = 4.98

Y = 1 × 2 = 2

The simple ratio of X:Y is 5:2, hence, their empirical formula is X5Y2.

Answer:

73.97 kPa

Explanation:

It's helpful to know the conversion factors and apply them.

First, convert from torr to atm:

555 torr ÷ 760 atm = 0.730 atm

Next, convert from atm to Pa:

0.730 atm × 101,325 Pa = 73967 Pa

Finally, convert to kPa (1000 Pa in 1 kPa):

73967 Pa ÷ 1000 kPa = 73.97 kPa

Answer:

60g

Explanation:

The molar mass of a substance (Atom or molecule) is defined as the mass in grams that 1 mole of substance (6x10²³ particles of this substance) weighs. Using the periodic table of elements we can know the molar mass of each atom.

For example, the molar mass of Calcium is 40.078g / mol.

That means the mass of 1.5 moles of calcium atoms must be:

1.5 moles * (40.078g / mol) =

Took the T E S T

The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons.

Answer:

its basically represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines the place of the element in the periodic table

For a given substance, the molar heat of fusion basically tells you one thing from two perspectives

how much heat is needed in order to melt one mole of that substance at its melting point

how much heat must be removed in order to freeze one mole of that substance at its freezing point

It is very important to realize that the molar enthalpy of fusion will carry a positive sign when you're dealing with melting and a negative sign when you're dealing with freezing.
