A wave on a lake has a wavelength of 5.0 M and a Frequency of 4 Hz. What is the speed of the wave in m/s?

Answers

Answer 1

Answer:

The appropriate speed will be "20 m/s".

Explanation:

The given values are:

Wavelength,

λ = 5.0 M

Frequency,

f = 4 Hz

Now,

The speed of the wave will be:

⇒ [tex]V=f\times \lambda[/tex]

On putting the values, we get

⇒     [tex]=4\times 5.0[/tex]

⇒     [tex]=20 \ m/s[/tex]

Answer:

Molecular formula = SF₆

Empirical formula is SF₆

Explanation:

Percentage of sulfur = 21.95%

Percentage of fluorine = 78.03%

Molar mass of compound = 146.1 g/mol

Empirical formula = ?

Molecular formula = ?

Solution:

Number of gram atoms of S = 21.95 / 32= 0.69

Number of gram atoms of F = 78.03 / 19 =  4.107

Atomic ratio:

                                  S                  :         F

                                0.69/0.69      :       4.107/0.69

                                     1                :         6

S : F =  1:6

Empirical formula is SF₆

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass :

32 + 19×6 = 146

n = 146.1 / 146

n = 1

Molecular formula = n (empirical formula)

Molecular formula = 1 (SF₆)

Molecular formula = SF₆

What is the metallic ion in the compound CuCl2?

Answers

Answer:

Cu2+

Srry if I didnt help..

The metallic ion in the compound CuCl₂ is copper (Cu).

What is the metallic ion in the compound CuCl2?

CuCl₂ is a combination of copper (Cu) and chlorine (Cl) ions. In this compound, copper has a positive charge of 2, and chlorine has a negative charge of 1. Copper is a type of metal that can make different charged particles (called ions) depending on what it combines with and how it reacts.

In CuCl₂, the copper ion has a positive charge of 2. This means that it has given away two electrons and has an oxidation state of +2. The chlorine ions have a negative charge of -1 because they have taken in one electron. This shows that they have an oxidation state of -1.

what is the mass of 1.506 x 10^24 atoms of Argon

Answers

Answer:

99.90g

Explanation:

1.506 x 10^24atoms × [tex]\frac{1mol}{6.022*10^{23}atoms}[/tex] × [tex]\frac{39.948grams}{1mol}[/tex] = 99.90grams

multiply the atom by constant and by its molar mass

1.506 x 10²⁴ atoms of argons gas is two moles. One mole of argon weighs 35.9 g. Thus mass of two moles of argon is 89.9 g.

What is argon?

Argon is 18th element in periodic table. It is placed in 18 the group and it is a noble gas or inert gas with completely filled orbitals. The group members of argon are neon, krypton, xenon and radon.

One mole of every substance contains 6.022 × 10²³ atoms. This number is called Avogadro number. Therefore, one mole of every element contains Avogadro number of atoms. The atomic mass of an element is the mass of one mole of that element.

Mass of one mole of argon is 35.9 g. Thus, it contains  6.022 × 10²³ atoms. Hence, the number of moles that contains  1.506 x 10²⁴ atoms is calculated as follows:

no.of moles =  1.506 x 10²⁴  / 6.022 × 10²³

                    = 2.5 moles.

The mass of 2.5 moles of argon is 2.5 × 35.9 = 89.9 g. Hence, the mass of  1.506 x 10²⁴ argon atoms is 89.9 g.

Pedro is heating sugar to make caramel for an investigation. As the sugar is heating, he is looking for evidence of a chemical change. Select the observation that Pedro made about the chemical change.

Answers

Answer:

The sugar atoms formed new atoms after caramelization.

Explanation:

When sugar is heated to a certain temperature, it becomes caramel. Te formation of caramel from the sugar is a chemical process.

In the context, Pedro is doing an investigation by heating sugar to make caramel. Burning of the sugar crystal is a chemical change as different chemicals are present in both. The caramel formed cannot be revered back to sugar crystal, this also proves the chemical change of caramelization of sugar cubes. Sugar consists of carbon, oxygen and hydrogen atoms. It reacts with atmospheric oxygen atoms to form new groups of atoms and forms caramel.

Answers

Answer:

521 nm

Explanation:

From the question given above, the following data were obtained:

Frequency (v) = 5.76×10¹⁴ s¯¹.

Wavelength (λ) =.?

RECALL: velocity (c) of light = 3×10⁸ m/s

Thus, we can obtain the wavelength of the green light by using the following formula:

c = vλ

3×10⁸ = 5.76×10¹⁴ × λ

Divide both side by 5.76×10¹⁴

λ = 3×10⁸ / 5.76×10¹⁴

λ = 5.21×10¯⁷ m

Next, we shall convert 5.21×10¯⁷ m to nanometer (nm). This can be obtained as follow:

1 m = 1×10⁹ nm

Therefore,

5.21×10¯⁷ m = 5.21×10¯⁷ m × 1×10⁹ nm / 1 m

5.21×10¯⁷ m = 521 nm

Thus, 5.21×10¯⁷ m is equivalent to 521 nm

Therefore, the wavelength (λ) of the photon of the green light is 521 nm.

Answer:

the wavelength (λ) of the photon of the green light is 521 nm.

How does the atomic radius of an element is related to its metallic character

Answers

Answer:

The large the atomic radius the more the metallic character of elements

Explanation:

The atomic radius is related to the metallic character in a way that the larger the atomic radius, the more metallic a body becomes.

Therefore, as we go down a group, metallic character increases.

Metallic character relies on the ability and willingness of an atom to share its valence electrons. As the size of an atom becomes large, the more metallic it is and the more its metallic character. In some other cases this character is known as electropositivity.
