Explanation:

A wind turbine transforms the mechanical energy of wind into electrical energy. A turbine takes the kinetic energy of a moving fluid, air in this case, and converts it to a rotary motion. As wind moves past the blades of a wind turbine, it moves or rotates the blades. These blades turn a generator.

IS A SUBSTANCE AND MIXTURE

Explanation:

In general, atoms are most stable, least reactive, when their outermost electron shell is full. Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.

Answer:

The atmosphere and Earth's interior are layered by density. The differentiation between these layers is due to processes that took place during the early stages of Earth's formation (ca. 4.5 billion years ago). At this time, melting would have caused denser substances to sink toward the center while less-dense materials would have migrated to the crust.

Gravity pulls more strongly on denser materials so denser materials are at the center of things.

Explanation:

Gravity pulls more strongly on denser materials so denser materials are at the center of things. The lowest layer of the atmosphere is denser than the upper layer. Earth's liquid metal core has convection, which generates the magnetic field.

Denser materials are in the centre of the universe because they are more powerfully pulled toward the centre by gravity.

The force that pulls items toward the centre of a planet or other entity is called gravity. All of the planets are kept in orbit around the sun by gravity.

Gravity applies to anything that has mass. Gravity is stronger for objects with higher mass. Along with distance, gravity weakens as well. Therefore, the gravitational force of two things becomes stronger the closer they are to one another.

The mass of the Earth is what creates gravity. The total gravitational force of all of its mass acts on the weight in your body. What gives you weight is that. Additionally, you would weigh less than you do now if you were on a planet with a lower mass than Earth.

Gravity applies to anything that has mass. Gravity is stronger for objects with higher mass. Along with distance, gravity weakens as well. Therefore, the gravitational force of two things becomes stronger the closer they are to one another.

Therefore, denser materials are closer to the centre of the universe because gravity is more drawn to them.

Answer:   1.15 × 10⁷ Hz

Explanation:

Frequency = Speed of Light ÷ Wavelength  

                   = (2.99 × 10⁸ m/s) ÷ (2.6 × 10 m)    

                   = 1.15 × 10⁷ Hz

The frequency of a wave of wavelength 2600 cm is 1.15 × 10⁷ Hz

Notes:

Hz ≡ /s

1 m = 100 cm

The frequency of a 2,600 cm wave is 1.15 × 10⁷ s⁻¹

From the question,

We are to determine the frequency of a wave with wavelength 2600 cm.

Using the formula

[tex]c = \nu \lambda[/tex]

Where c is the speed of light (c = 3.0 × 10⁸ m/s)

[tex]\nu[/tex] is the frequency

[tex]\lambda[/tex] is the wavelength

Then, we can write that

[tex]\nu = \frac{c}{\lambda}[/tex]

From the question

λ = 2600 cm = 26 m

Putting the parameters into the formula, we get

[tex]\nu = \frac{3.0 \times 10^{8} }{26}[/tex]

[tex]\nu = 0.11538 \times 10^{8}[/tex]

[tex]\nu \approx 1.15 \times 10^{7} \ s^{-1}[/tex]

Hence, the frequency of a 2,600 cm wave is 1.15 × 10⁷ s⁻¹

As per the balanced reaction, two moles or 319.4 g of Fe₂O₃ gives 4 moles or 223.4 g of Fe. Thus 6.10 g gives 4.22 g of Fe.

What is ferric oxide?

Ferric oxide is an ionic compound formed from iron and oxygen in which iron is in  +3 oxidation state. It is also called iron oxide which decomposes to form molecular oxygen and iron.

The balanced equation giving Fe and oxygen from ferric oxide is written below:

[tex]\rm 2Fe_{2}O_{3} \rightarrow 4Fe + 3O_{2}[/tex].

The molar mass of ferric oxide is 159.7 g/mol. Thus two moles weighs 159.7 × 2 = 319.4 g. Atomic mass of Fe is 55.85 hence, 4 moles is 223.4 g.

As per the balanced reaction, 319.4 g of ferric oxide gives 223.4 g of iron. Thus mass of iron , Fe produced from 6.10 g of ferric oxide is calculated as follows:

mass of Fe = (223.4× 6.10 ) /319.4

                  = 4.226 g

Hence, 4.22 g of Fe will be produced from 6.10 g of Fe₂O₃.

1) A. The reactants and products have the same number and type of atoms, but the atoms may be recombined.

2) B. It shows how many molecules there are of a particular substance.

3) D. NaOH + HCl → NaCl + H2O

4) A. Atoms always remain intact during chemical reactions.

5) D. 4, 4

The balanced chemical equation is:

CH₄ + 4Cl₂ —> CCl₄ + 4HCl

The numbers that balanced the equation are: 4, 4

To know the number that balanced the equation, we shall simply balance the equation.

CH₄ + Cl₂ —> CCl₄ + HCl

There are 4 atoms of H on the left side and 1 atom on the right side. It can be balance by writing 4 before HCl as shown below:

CH₄ + Cl₂ —> CCl₄ + 4HCl

There are 2 atoms of Cl on the left side and a total of 8 atoms on the right side. It can be balance by writing 4 before Cl₂ as shown below:

CH₄ + 4Cl₂ —> CCl₄ + 4HCl

Now, the equation is balanced

The numbers that balanced the equation are 4,4
