what would the answer be? if you could help that would be a big help ^^

The equation Fe + CuSO₄ → Cu + FeSO₄ illustrates the single displacement reaction. Hence Option (D) is the correct answer.

A single replacement reaction, sometimes called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound.

The starting materials are always pure elements, such as a pure zinc metal, iron or hydrogen gas, plus an aqueous compound.

Therefore, the equation Fe + CuSO₄ → Cu + FeSO₄ illustrates the single displacement reaction. Hence Option (D) is the correct answer.

Answer:

parietal pleura

Explanation:

The pleurae, which are serous membranes, divide the thoracic cavity's wall from the lungs. The parietal pleura covers the interior of the thorax, mediastinum, and diaphragm, while the visceral pleura covers the surface of the lungs.

The perianal pleura, the outer layer, is attached to the chest wall. The lungs, mediastinum's neurovascular structures, and bronchi are all covered by the inner layer (visceral pleura).

The pleura's role in breathing is to enable the lungs to expand and collapse as efficiently as possible.

The parietal and visceral pleura can move over one another without rubbing against one another thanks to the pleural fluid's lubricating properties. The pleural layers themselves produce this fluid.

Therefore, parietal pleura, which surround the lungs in thoracic cavity.

Answer:

Due to static charges.

Explanation:

In the illustration, we can see that when we bring the magnet close to the body, the static charges present on the body rearrange theirselves and attracted by the magnet. The magnetic substance is responsible for the arrangement of charges on the body and when they are arranged, they attract each other so we can say that static charges are present on the body and rearrangement occurs in the body.

B. Carbon and Hydrogen

Explanation:

An alkyne can be regarded as unsaturated hydrocarbon which have at least one carbon—carbon triple bond. They are acyclic aliphatic hydrocarbons, they can be (branched or unbranched) , They have general chemical formula of [ CₙH₂ₙ−2]. One of the compound belonging to this family is Propyne( C3H4) Hence, they contain Hydrogen and Carbon.

Alkenes can be regarded as class of hydrocarbons which posses only carbon and hydrogen, they are unsaturated compounds having least one carbon-to-carbon double bond.

alkenes can also be regarded as "olefins". one of the members of this family is Ethene (C2H4). general formula of alkenes can be written as [C nH 2n],

Explanation:

The can chiller has a cooling system which expels heat around the immediate vicinity of the can chiller.

Let us remember that convection is a mode of heat transfer that occurs as a result of the actual movement of the particles of a substance. In this case, we are going to consider the movement of air molecules.

As the can chiller expels heat, the air molecules around the can chiller become heated and less dense and begin to move away from the can chiller. They are quickly replaced by cold denser air.

This process of cycling of hot/cold air molecules is known as a convection current. It is set up as a result of the working of the can chiller.

Answer:

Radiation isn't beneficial to society .Radiation damages the cells that make up the human body. Low levels of radiation are not dangerous, but medium levels can lead to sickness, headaches, vomiting and a fever. High levels can kill you by causing damage to your internal organs. It's difficult to treat high radiation exposure.

Explanation:

Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.

Radiation is both harmful and beneficial, but when we analyse it is found that harms overweight benefits. Radiation can be used as a form of energy (in nuclear plants), but an accident or malfunction in it can lead to death and injury of humans. Also, it is really difficult to dispose the used devices.

In animal skin tissue, cell division is responsible for growth and repair. The correct answer is option A.

Cell division is the process by which a single cell divides into two or more daughter cells. This process is essential for growth, repair, and reproduction in living organisms.

Cell division in animal skin tissue is responsible for growth and repair. When the skin is damaged, cells divide to repair the damaged area.

There are two main types of cell division:

Additionally, cell division is responsible for the growth of skin tissue during development and throughout the life of the organism.

Therefore, the correct answer is option A. Growth and repair.

a) The genotype is Hh. We simply combine the two given letters together to get this genotype.

b) The phenotype is Widow's peak. The uppercase letter is the dominant allele, while the lowercase is recessive. Any presence of the dominant allele (even a single letter) will mean the dominant phenotype will present itself. We can see that HH leads to Widow's peak phenotype, so that applies to Hh as well. Only when there isn't a dominant allele at all, the genotype hh, is when the recessive phenotype will show up.

The correct answer is A

Explanation:

A radio telescope is used to detect, collect and focus radio waves from distant objects in the sky or space. While a compound telescope, by design, can both refract and reflect waves. A reflection telescope uses curved mirrors to reflect light to form an image. A refraction telescope forms an image using a lens as its objective.

From the above definitions, it can be deduced that option A is the correct answer.

Answer:

6 Watts

Explanation:

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

Current (I) = 0.05 A

Voltage (V) = 120 V

Power (P) =?

Electrical power is defined by the following equation

The power consumption while the TV is in standby can be obtained as follow:

Power (P) = Current (I) × Voltage (V)

P = IV

With the above formula, we can obtain the power consumption while the TV is in standby. This can be obtained as follow:

Current (I) = 0.05 A

Voltage (V) = 120 V

Power (P) =?

P = IV

P = 0.05 × 120

P = 6 Watts

Therefore, the power consumption while the TV is in standby is 6 Watts.

Answer: A pattern of same atomic orbitals can be seen about elements in the same period with respect to electron structures.

Explanation:

The horizontal rows in a period table are called periods.

Elements present in the same period will have same atomic orbitals.

For example, electronic distribution of Na is 2, 8, 1 and it is a third period element.

Similarly, electronic distribution of Cl is 2, 8, 7 and it is also a third period element.

Hence, both Na and Cl will have K, L, M shells, that is, they have three atomic orbitals.

Thus, we can conclude that a pattern of same atomic orbitals can be seen about elements in the same period with respect to electron structures.

There would be 9.03 x  [tex]10^{23}[/tex] particles in 13.5 grams of Beryllium.

Recall that 1 mole of a substance contains 6.02 x 10^23 atoms.

Number of moles in 13.5 grams of Beryllium = mass/molar mass

                    = 13.5/9

                       = 1.5 moles

Thus, total number of atoms in 1.5 moles Beryllium:

             = 1.5 x 6.02 x 10^23
