C Cl is a covalently bonded compound with the formula CCl₄. MgCl is an ionic compound with the formula MgCl₂.

The formation of a chemical bond between two or more atoms, ions or molecules to form a chemical compound is known as chemical bonding. The chemical bonding makes sure the atoms are together in the resulting compound.

Chemical bonding is made possible by an attractive force resulting from the overall loss of energy in the resultant molecule compared to its constituents.

Chemical compounds depend on chemical bonding for their stability. There are various kinds of chemical bonds formed. Covalent bonds and ionic bonds are 2 of the most commonly known chemical bonds.

Covalent bonds are formed by the sharing of electrons and an ionic bond is formed by the electrostatic force of attraction between the atoms.

Therefore, in the given examples, C Cl is a covalently bonded compound with the formula CCl₄. MgCl is an ionic compound with the formula MgCl₂.

The bond of the following atoms in C-Cl and Mg-Cl is polar covalent bond in C-Cl  and  Mg-Cl ionic bond.

Polar covalent bonds are created between two non-metal atoms or molecules  that do consist of different  electronegativity. and the electronegativity difference that is not equal to zero and the shared pair of electrons forming a bond between will always be towards the high electronegative atom.

An ionic bond the  complete sharing or the  electron transfer. Ionic bonds basically form or created when the difference in the electronegativity of the two atoms is great or more as compare to   covalent bonds form when the electronegativity is same.

Therefore,  bond of the following atoms in C-Cl and Mg-Cl is polar covalent bond in C-Cl  and  Mg-Cl ionic bond.

Answer:

D

Explanation:

Answer:

1. D

2. A

Explanation:

Answer:

This question is incomplete as it lacks the options for each hypothetical statement. The options for each hypothesis are:

wood, clay brick, iron, aluminum, copper, or nickel

The answers to each hypothesis are:

1. Wood

2. Clay brick

3. Copper

4. Iron

Explanation:

Firstly, a hypothesis is a testable explanation given to explain an observed problem or to answer a question. In this case, "which materials will meet the special needs of Parvus' house?" is the question.

The question requires one to complete the given hypotheses using the options given.

- If we use WOOD to build the roof of the house, then the temperature inside the house will remain cooler. The best answer is "wood" because wood conducts/absorbs heat the least among the materials that can be used for roofing, hence, it will make the inside of the house cooler.

- If we use CLAY BRICK to build the walls and floors of the house, then the temperature inside the house will remain cooler. Clay brick is the best material for building walls and floors of a house among the option. Also, it conducts heat fairly making the interior of the house cool.

- If we use COPPER to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate. Copper, among all other metal, is the best conductor of electricity due to its properties including low resistivity. Hence, using copper will make electricity to flow into the home at a faster rate.

- If we use IRON to construct the latches on the windows and doors, then the magnetism will keep the latches secure. Iron is the metal with the best magnetic property. Therefore, using it to construct the latches on the windows and doors will guarantee magnetic security.

Answer:1-Diffusion

2-Cerebral edema

Explanation:

The process of water migrating from areas of low electrolyte concentration to areas of high electrolyte concentration is called diffusion.

Cerebral edema is the medical term for the swelling of the brain.

Diffusion is a process where the substance or ions of from a low concentration to a high concentration. It occurs against the concentration gradient, so it needs energy.

Cerebral edema is a condition where fluid gets filled in the brain and the brain swells and make pressure on the skull called intracranial pressure.

Thus, Diffusion is the mechanism by which water moves from regions with low electrolyte concentrations to regions with high electrolyte concentrations.

The medical term for brain swelling is cerebral edema.

LIQUID

Explanation:

The substance found to change shape in a different container but maintained volume is most likely a liquid.

Matter is any substance that has weight and occupies space. Matter can exist in three different states namely:

Liquid as a state of matter is characterized by weak bonds that holds its particles together, hence, liquids flow.

Liquids assume the shape of the container that holds them. Hence, according to this question, the substance found to change shape in a different container but maintained volume (50ml) is most likely a liquid.

Explanation:

An electron has a negative charge and a proton is a positively charged particle. Electric field lines are used to express the direction of the electric field. For a positive charge, it is outwards while for a negative charge it is inwards. The attached figure shows the electric field lines between a proton and an electron. The field lines emerge from proton and terminate at electron.

The electrical force between charges is given by :

[tex]F=k\dfrac{q_1q_2}{r^2}[/tex]

r is the distance between charges

The force is directly proportional to the product of charges. It means that if the product of electrical charge increased, it means that the electrical force will increase proportionally.

Explanation:

all you have to do is divide them its simple division cause its by the volume by the density

Mass can be calculated by using moles which can be further calculated from multiplication of Molarity to volume. The mass of sugar to make this solution is  8.6 kg.

Molarity can be calculated by dividing  number of moles of solute by volume of solution in litre. Molarity is affected by temperature. Its unit is mole/litre. It measure the concentration of any solute in a solution.

Other concentration terms are molality, normality and mole fraction. Molarity can be used to find out the ionic strength of any solution

Mathematically,

Molarity= number of moles of solute/volume of solution in litre

Where,

moles= given weight /by molecular weight

         = w/ 96.0858

Substituting values in equation 1

0.6=(w/96.0858)/(150 )

w=8.6 kg

Thus the mass of sugar is 8.6 kg.

Explanation:

(1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... (3) Rates of chemical reactions are influenced by temperature and catalysts.

Answer:

cannot be used to produce energy in reactors.  

Explanation:

Currently, there is no reactor that can allow the use of nuclear fusion, although nuclear plants use nuclear fission reactors.

Nuclear fusion happens when thousands of atoms collide with each other when they are in the midst of extreme conditions of literature and pressure. This collision causes the atoms to fuse, creating another element. The process releases amounts of light and heat, promoting a high release of energy. This whole process occurs without the release of CO2 into the atmosphere, without the release of toxic waste and without the risk of explosions, which makes nuclear plants have a strong interest in building a reactor to use this type of energy. For this reason, scientists from different countries have collaborated with each other on a project called Iter, which seeks to build a reactor and achieve the first reaction in 2025.

Answer:

29. Proteins support the body's structural framework, chemical reactions, and contractions (muscle movement).

30. Proteins have a primary structure (polypeptide chain of amino acids), secondary structure (made up of alpha helices and beta pleat sheets), tertiary structure (superimposed on secondary structure), and quaternary structure (2 or more polypeptide chains with its own tertiary structure).

31. Protein molecules can denature if conditions aren't right, such as the wrong temperature or pH level. When denatured, proteins typically lose their shape and their function for a short time because their active sites become deactivated (though if conditions are too extreme, they can permanently lose their function). This happens to globular proteins because they are not nearly as stable as fibrous proteins due to their functional 3D shape.
