Why do atoms share electrons in covalent bonds?

A. to attain a noble-gas electron configuration

B. to become more polar

C. to become ions and attract each other

D. to increase their atomic numbers​

Answers

Answer:

Answer Option A) To attain a noble-gas electron configuration.

Explanation:

Correct answer from test

Taking into account the definition of covalent bond and octet rule, the correct answer is option A.  Atoms share electrons in covalent bonds to achieve a noble gas electron configuration.

The covalent bond is the chemical bond that occurs between atoms of non-metallic elements. These atoms have many electrons at their outermost level and have a tendency to share them to acquire the stability of the noble gas electronic structure. In this way a molecule is formed.

The tendency of the elements to reach a stable configuration is known as the octet rule. For this, the octet rule explains that there must be eight electrons in their last energy levels, thus acquiring the structure of a noble gas.

So, a covalent bond is a force that joins two atoms of non-metallic elements to form a molecule in order to comply with the octet rule.

Finally, the correct answer is option A.  Atoms share electrons in covalent bonds to achieve a noble gas electron configuration.

Which indicates that thermal energy is no longer being transferred from boiling water to a mug?

The mug and the water lose all thermal energy.
The water is hotter than the mug.
The mug is hotter than the water.
The water and the mug are the same temperature.

Answers

Answer:

Which indicates that thermal energy is no longer being transferred from boiling water to a mug?

The mug and the water lose all thermal energy.

The water is hotter than the mug.

The mug is hotter than the water.

•The water and the mug are the same temperature.

Explanation:

answer #D is correct

When the water and the mug are at the same temperature then thermal energy will no longer be transferred from the boiling water to the mug. Therefore, option (D) is correct.

What is thermal energy?

Thermal energy is generated in a substance when an increase in temperature causes atoms and molecules to move at a faster speed and result in the molecules colliding with each other. The energy generated from the temperature of the heated material is called thermal energy.

Thermal Energy or internal kinetic energy is because of the random motion of molecules in the system. The thermal energy of any system is directly proportional to its temperature.

The more the temperature of the system, the more the movement of molecules within a given system, and the more the thermal energy of the system.

The thermal energy will be transferred from the boiling water to the mug when the water is hotter than the mug. When both have the same temperature then the thermal energy is no longer being transferred from boiling water to a mug.

There is a storage container with 5.25 tons of Ammonia (NH3). How many molecules of Ammonia are there?

Answers

Answer:

1.69×10²⁹ molecules.

Explanation:

The following data were obtained from the question:

Mass of Ammonia (NH3) = 5.25 tons

Molecules of Ammonia (NH3) =.?

Next, we shall convert 5.25 tons to grams (g). This can be obtained as follow:

1 ton = 907184.74 g

Therefore,

5.25 ton = 5.25 ton × 907184.74 g / 1 ton

5.25 ton = 4762719.885 g

Therefore, 5.25 tons is equivalent to 4762719.885 g

Finally, we shall determine the number of molecules of ammonia, NH3 in 4762719.885 g. This can be obtained as follow:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ molecules. This implies that 1 mole of ammonia, NH3 also contains 6.02×10²³ molecules.

1 mole of ammonia, NH3 = 14 + (3x1) = 14 + 3 = 17 g

17 g of ammonia, NH3 contains 6.02×10²³ molecules.

Therefore, 4762719.885 g of ammonia, NH3 will contain = (4762719.885 × 6.02×10²³) / 17 = 1.69×10²⁹ molecules.

From the calculations made above,

5.25 tons (4762719.885 g) of ammonia, NH3 contains 1.69×10²⁹ molecules.

A metal object has a density of 2 g/ml. When placed in a graduated cylinder with 500 ml of water, the
water rises to 508 ml. What is the mass of the metal object?

Answers

Answer:

The answer is 16 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

density = 2 g/ml

volume = final volume of water - initial volume of water

volume = 508 - 500 = 8 mL

We have

mass = 2 × 8

We have the final answer as

16 g

what is biogas, biomass and biodigester​

Answers

Answer:

Biogas is a type of biofuel that is naturally produced from the decomposition of organic waste. When organic matter, such as food scraps and animal waste, break down in an anaerobic environment (an environment absent of oxygen) they release a blend of gases, primarily methane and carbon dioxide.

Explanation:

Biomass is renewable organic material that comes from plants and animals. ... Biomass contains stored chemical energy from the sun. Plants produce biomass through photosynthesis. Biomass can be burned directly for heat or converted to renewable liquid and gaseous fuels through various processes.biodigester is like a mechanical stomach. It is fed with organic material, which is broken down (decomposed) by micro-organisms (bacteria) is an oxygen-free (anaerobic) environment to produce a renewable energy called biogas (methane and carbon dioxide) and other material that is mainly used as fertilizer.

Explanation:

Biogas is a type of biofuel that is naturally produced from the decomposition of organic waste.

Biomass is plant or animal material used for energy production, or in various industrial processes as raw substance for a range of products.

A Biodigester simply means a tank which digests organic material biologically. In this sense, the FilterPod is a biodigester. However, many people think of a biodigester as a tank which digests, anaerobically, without air, organic material and produces methane gas for cooking, lighting and heating ect.

In science class, a student is given a copper cylinder to investigate. The student measures the mass of the cylinder as 53.76 grams. The
student measures the volume of the copper as 6 cm. Which additional property of the copper can the student determine from these
measurements?

Answers

Answer:

From these two values, i.e. mass and volume, density of the copper cylinder can be calculated.

Formula of density is :

Density = Mass / volume.

Now we have mass: 53.76g and volume 6cm³

Density = 53.76 / 6

Density= 8.96 g/cm³

C) Aldehydes are similar to ketones, but their carbonyl group is located in the middle of the carbon chain.

D) In ketones, the carbon of their carbonyl group is bonded with one other carbon.

Answers

Answer:

A) In aldehydes, the carbon is always joined to at least one hydrogen atom.

Explanation:

Aldehydes and Ketones are organic compounds.

The main difference between them is that aldehydes have the carbon atom attached to at least one hydrogen atom.

In ketones, the carbon is attached to another carbon.

The IUPAC names of alkanals usually end with -eFor alkanones usually end with -one

To reiterate, the striking difference between the two families is that in alkanals, a hydrogen atom is directly attached to the carbonyl group while in alkanones, no hydrogen atoms is attached to the carbonyl group but two bulky alkyl groups.
