Hydrogen gas and nitrogen gas can react to form ammonia according to the following equation N2 (g) + 3H2 (g) 2NH3(g)

Once an action potential reaches the end bulbs of a neuron, the first event in synaptic transmission is the release of neurotransmitters from the presynaptic neuron.

When an action potential reaches the end bulbs, it causes the opening of voltage-gated calcium channels in the presynaptic membrane. This influx of calcium ions into the presynaptic neuron triggers the release of neurotransmitters stored in vesicles at the synapse.

The neurotransmitters then diffuse across the synaptic cleft, the small space between the presynaptic and postsynaptic neurons, and bind to receptors on the postsynaptic membrane. This binding causes a change in the electrical or chemical properties of the postsynaptic neuron, leading to the initiation or inhibition of an action potential in the postsynaptic neuron.

It's worth noting that, this process is called synaptic transmission, it's the process by which an action potential in one neuron causes an electrical or chemical signal in another neuron, muscle cell or gland cell.

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.

Answer:

A.

Explanation:

Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Xenon(Xe ) is the least abundant element on the earth. The correct option is option A.

Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.

Oxygen, water, and nitrogen are the most abundant molecule on the earth. Xenon is the least abundant amongst all given option. Xenon belongs to noble gas family. So, Xenon is not reactive at all.  Xenon does not form any compound with any other element so its abundance on earth is very less.

Therefore,  Xenon(Xe ) is the least abundant element on the earth. The correct option is option A.

Explanation:

Solvent is the material that is dissolving another material​. Thus, option D is correct.

A solvent is a substance that dissolves another substance to form a solution. The substance that is being dissolved is called the solute, and the substance that is doing the dissolving is called the solvent. The solute is usually present in a smaller amount than the solvent, and it is the solvent that determines the physical properties of the solution, such as its density, viscosity, and boiling point.

For example, when salt is dissolved in water, the salt is the solute and the water is the solvent. The water molecules surround the salt molecules and break them apart, so that the salt ions are free to move around in the solution. The solution is then a homogeneous mixture of salt ions and water molecules.

Thus, option D is correct.

Yes, Phong shading can simulate properties of water or liquid metal. It can simulate properties such as metal, wood, etc.

Phong shading is a technique used in computer graphics to approximate the appearance of different surfaces under varying lighting conditions. It does this by interpolating the surface normals across a polygon and calculating the lighting for each pixel.

This method can be used to simulate the properties of various materials, including metal, wood, and even water or liquid metal.
In the case of water or liquid metal, Phong shading can be used along with additional techniques such as reflection, refraction, and transparency to achieve a more realistic appearance. This is because water and liquid metals have specific optical properties that require special treatment, such as the way they reflect and refract light, as well as their transparency.
By combining Phong shading with these additional techniques, it is possible to create a convincing simulation of water or liquid metal in computer graphics.
Phong shading, when used in conjunction with other techniques, can effectively simulate the appearance of various materials, including water and liquid metal.

Answer:

0.5667 M ≅ 0.57 M.

Explanation:

It is known that the no. of millimoles of a solution before dilution is equal to the no. of millimoles of the solution after the dilution.

It can be expressed as:

(MV) before dilution = (MV) after dilution.

M before dilution = 1.5 M, V before dilution = 340 mL.

M after dilution = ??? M, V after dilution = 340 mL + 560 mL = 900 mL.

∴ M after dilution = (MV) before dilution/(V) after dilution = (1.5 M)(340 mL)/(900 mL) = 0.5667 M ≅ 0.57 M.

Organic molecules are more diverse compared to inorganic molecules due to the unique properties of carbon, its ability to form covalent bonds with other elements, and the presence of functional groups, allowing for a wide range of molecular structures and chemical reactions.

Organic molecules are primarily composed of carbon atoms, which possess a unique ability to form strong covalent bonds with other atoms, including carbon itself. Carbon atoms can bond with up to four other atoms, enabling the formation of complex and varied molecular structures. This property, known as catenation, allows carbon to form long chains, branched structures, and ring systems, resulting in an immense diversity of organic compounds.

Furthermore, carbon atoms can also bond with other elements such as hydrogen, oxygen, nitrogen, sulfur, and phosphorus, forming functional groups. These functional groups significantly influence the chemical behavior and reactivity of organic molecules. They introduce specific characteristics and properties, such as acidity, basicity, polarity, and the ability to undergo various types of reactions. The presence of functional groups further expands the possibilities for molecular diversity in organic compounds.

In contrast, inorganic molecules typically lack the same level of structural complexity and diversity found in organic molecules. While inorganic compounds can exhibit a range of chemical properties and reactions, they are often limited by the nature of their bonding and the types of elements involved. Inorganic molecules predominantly involve ionic bonding, where electrons are transferred between atoms, resulting in simpler and more repetitive structures

The energy can travel through empty space without being carried in or by any matter is light.

What is light?

light is an electromagnetic wave and it can travel through a vacuum such as the empty parts of outer space. electromagnetic wave means it has both the proprties of electric field and magnetic field. In a model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and light.

What is the travelling speed of light?

In empty space, light travels at a speed of about 300,000 km/s. It does not require any substance or material to transport its energy. This means that light can pass across a vacuum—a place devoid of any air.

Answer:

Empirical formula is Na₂CO₃

Molecular formula is Na₂CO₃

Explanation:

Percentage compositions of the elements;

Sodium = 46%

Carbon = 12 %

Oxygen = 42%

To determine empirical formula, we calculate the mole ratio first.

mole ratio =  % mass/atomic mass; where the atomic masses of the elements are :  Na = 23 u, C = 12 u and O = 16 u.

mole ratio: Na = 46/23; C = 12/12; O = 42/16

mole ratio (Na : C : O) = 2 : 1 : 2.6

approximate mole ratio = 2 : 1 :3

Therefore, empirical formula of compound is Na₂CO₃

To determine the molecular formula;

molecular formula or mass = n(empirical formula or mass)

n = molecular mass/empirical mass

molecular mass = 106 u,

empirical mass = 23*2 + 12 + 16*3 = 106 u

then, n = 106/106 = 1

therefore, molecular formula = 1 * (Na₂CO₃) = Na₂CO₃
