Photoautotroph has been derived from the combination of three words, photo -meaning "light", autos- meaning "self", and troph meaning "nutrition".

Land plants and photosynthetic algae are both photoautotrophs. These species contain pigments that can capture light, like chlorophyll. Origin of the word: photo- (light) + auto (self) + troph (nourishment). Autotrophs known as photoautotrophs generate complex chemical substances like proteins, lipids, and carbohydrates by absorbing light. Photosynthesis is the name given to this light-mediated process.

An energy-rich carbohydrate like glucose is produced by plants using carbon dioxide, inorganic salts, and water during a process called photosynthesis. As a byproduct, oxygen is also produced, other than glucose. Land plants and photosynthetic algae are both photoautotrophs. These species contain pigments that can capture light, like chlorophyll.

0.5 moles of carbon weigh 6.0055 grams.

One of the chemical elements is carbon. The letter C stands for carbon, and the letter g stands for grams. As a result, 0.5 moles of carbon per gram is equivalent to 0.5 moles of carbon per gram, 0.5 moles of carbon per gram, and 0.5 moles of C per gram.

Carbon has a 12.011 atomic mass. Thus, one mole of carbon has a mass of 12.011 grams (12.011 g/mol). We multiply 0.5 moles of carbon by 12.011 to get grams, and vice versa.

no. of Grams = Moles of Carbon x 12.011

                     =0.5 × 12.011 = 6.0055

0.5 moles of carbon equal 6.0055 grams.

The inland area has a Continental climate.

Inland climates are typically more severe. Summers might be quite hot, and winters could be very frigid. Rainfall can be scarce.

In inland area the water bodies take long time to heat up and cool down, so they absorb all the heat during the spring and summer when the sun is at its greatest before slowly losing it throughout the fall and winter when the temperature starts to drop.

On the other hand, it warms up and cools down far more quickly on land, that's why the  inland are more cooler.

Inland absorbs and releases heat energy more quickly than water, inland places typically experience higher temperature variations from day to night and from season to season, so that inland is hotter area also.

Ionic compounds can be classified as compounds formed between cation ions and an anion. A cation can be described as an electropositive ion and has the tendency to donate valence electrons. Similarly, anions are electronegative ions and have a tendency to accept electrons.

In an ionic compound, an ionic bond contains the complete transfer of electrons, therefore, there exists an electrostatic force of attraction that forms a strong bond.

In a covalent compound, the covalent bond exhibits the mutual sharing of electrons. Shared pairs of electrons are hard to give away as nuclei of two chemical elements together share the electrons and produce a bond stronger.

The pressure in the container can be calculated using Ideal gas law. The pressure of the gas at the reduced temperature will be 0.17 atm.

Ideal gas law states the relation between volume, pressure, temperature and number of moles of a gas as written below:

PV = nRT.

Where R is the universal gas constant equal to 0.082 L atm/ K mol.

Given , T = 100 K

n = 0.13 moles

V = 6.1 L

Answer:

The molarity of the solution is 0.29 [tex]\frac{moles}{liter}[/tex]

Explanation:

Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.

Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:

[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

In this case:

Replacing:

[tex]Molarity=\frac{2.1 moles}{7.3 liters}[/tex]

Molarity= 0.29 [tex]\frac{moles}{liter}[/tex]

The molarity of the solution is 0.29 [tex]\frac{moles}{liter}[/tex]

Answer:

M = 0.29 M

Explanation:

We are given;

Number of moles of NaCl; n = 2.1 moles

Total volume of solution; V = 7.3 L

Formula for molarity is;

M = n/L

Thus;

M = 2.1/7.3

M = 0.2878 M

Cooling magma becomes more dense and sinks, while hotter magma near the core is less dense and rises, moving magma in a cyclic path.

This answer was obtained from a credible source after doing some research.

The  temperature differences in the layers of Earth move magma as cooling  magma becomes more dense and sinks, while hotter magma near the core is less dense and rises, moving magma in a cyclic path.

Magma is the molten or semi-molten natural material from which all igneous rocks are formed.Magma is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural satellites.Besides molten rock, magma may also contain suspended crystals and gas bubbles.

Magma is produced by melting of the mantle or the crust in various tectonic settings, which on Earth include subduction zones, continental rift zones,mid-ocean ridges and hotspots. Mantle and crustal melts migrate upwards through the crust where they are thought to be stored in magma chambers or trans-crustal crystal-rich mush zones. During magma's storage in the crust, its composition may be modified by fractional crystallization, contamination with crustal melts, magma mixing, and degassing.

Electrons stay in between the nuclei of the two hydrogen atoms because they are attracted to the positive charge of the nuclei.

Electrons are negatively charged species, so they are attracted towards the positive charge of a nucleus.

In hydrogen atom, when both the two hydrogen atoms get close to each other then the electrons of each atom will get attracted to both the nuclei. And if both the hydrogen atoms come close to each other they will repel each other.

The energy of the two hydrogen atoms becomes less when  they are together than when they are far apart.

Thus, the electrons tend to stay in between the nuclei of the two hydrogen atoms.

A molecule's core atom experiences sp orbital hybridization. Around this primary atom, the geometry of the electron domain is linear.

In chemistry, hybridization is the idea of combining two atomic orbitals to create a new class of hybridized orbitals. Usually, this mixing creates hybrid orbitals with completely distinct energies, forms, etc. In hybridization, the same energy-level atomic orbitals are primarily involved. However, assuming they contain equal energy, both fully-filled and half-filled orbitals can participate in this process.

When two atomic orbitals unite to generate a hybrid orbital in a molecule, the energy of the orbitals of the individual atoms is redistributed to give orbitals of equivalent energy. Hybridization is the name given to this process. Atomic orbitals with similar points are brought together during the hybridization process.

Answer:The pOH of the solution is 9.914

Explanation:

pH is given as the negative logarithm (base 10) of the hydronium ion concentration [H₃O⁺] that is

pH= - log [H₃O⁺]

Since we are given  [H₃O⁺]=8.2 x 10⁻⁵,

pH=- log (8.2 x 10⁻⁵)

pH= 4.086

The pOH gives s the measurement of the concentration of OH− ions, Hence,

pH + pOH= 14

from the above calculation, we got  pH=4.086

So

4.086 + pOH=14

pOH= 14 - 4.086

pOH= 9.914

The pOH of the solution is 9.914

It is a matter of fact that the hydrophobic (water-hating) oily compounds of cannabinoids such as CBD, THC and others are not water soluble. The term "water soluble" refers to materials which dissolve in water in a homogenous manner by becoming molecules or ions (such as sugar, alcohol, and salt).

To determine the rate law for the reaction A + B -> products, we need to examine how the rate of the reaction changes as the concentrations of A and B change. From the given data, we can see that when the concentration of A is doubled, the rate of the reaction also doubles. Similarly, when the concentration of B is doubled, the rate of the reaction also doubles. This indicates that the rate of the reaction is directly proportional to the concentrations of both A and B.

Based on this information, the rate law for the reaction can be expressed as Rate = k[A]*[B], where k is the rate constant. The exponents x and y in the rate law represent the order of the reaction with respect to A and B, respectively. Since the rate of the reaction is directly proportional to the concentrations of both A and B, the exponents x and y would both be equal to 1.

Therefore, the values of x and y are C) x = 1 and y = 1.
