Explanation:

The physical adaptation among the option that increases an organisms

chances of finding a suitable habitat is the long legs of wading birds

An adaptation is a characteristic that helps an animal survive in its habitat.

Any animal who successfully survives on land or water must have behavioural

and physical trait or attributes or adaptation that assist it to achieve those

goals.

This physical adaptation might be body growth, body covering during

weather change, body functioning or even body parts.

The physical adaptation among the option that increases an organisms

chances of finding a suitable habitat is the long legs of wading birds.

The long legs of wading birds assist them to find a suitable habitat. The long

legs can move through shallow water without wetting their feathers.

There long leg give them better eye sight to search for food and suitable

habitats.

Answer:

Thermal energy consists of the total internal kinetic energy of an object due to the random motion of its atoms and molecules. It is related to heat and temperature.

Explanation:

The electron pair geometry around the central iodine in I3- is​ trigonal bipyramidal.

The shapes of molecules is determined by the Valence Shell Electron Pair Repulsion theory (VSEPR). According to this theory, The shape of a molecule depends on the number of electron pairs that surround the valence shell of the central atom in the molecule.

In the structure I3-, the iodine is sp3d hybridized and has a bond angle of 180°. There are three iodine atoms. The central iodine atom is surrounded by two bond pairs and three lone pairs. The  electron pair geometry around the central iodine in I3- is​ trigonal bipyramidal.

This is a not a spontaneous reaction.

Explanation:

No, it would not be one because if you add the reactants the products would have to be the same (same types of atoms. number of atoms, and the arrangement of the atoms). In this case the reactants and the products are not equal.

Answer:

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

Answer:

38.9%

Explanation:

below, determine the mass percent of Fe3+ in a 0.6450 g sample of iron ore, if 22.40 mL of a 0.1000 M stannous chloride, SnCl2(aq), solution is required to completely react with the Fe3+ present in the ore sample. The chemical equation for the reaction is

2 Fe3+ (aq) + Sn2+ (aq) →2Fe2+ (aq) + Snº+(aq).

O 19.40%

O 6.196%

O 38.79%

O 9.697%

 2 Fe3+ (aq) + Sn2+ (aq) →2Fe2+ (aq) + Snº+(aq).ole of Sn2+

for every mole of Sn2+, tere are 2 moles of Fe3+

so there are 0.00224 X 2= 0.00448 moles Fe3+

iron atomic mass is 56

56 X 0.00448 = 0.251 gm Fe3+

so the mass % of the Fe3+ in the 0.645 gm iron ore sample is

(0.251/0.645) X 100 = 38.9%

Answer:

24.3

Explanation:

Two containers of gas have the same volume, temperature and pressure. One container has a sample of oxygen gas having a mass of 3.95g. The other container has a gas with a mass of 2.99g. Determine the molar mass of the gas in the second container.

O2 has a molar mass of 16 X 2 =32

the number of moles for O2 is the weight divided by the molar mass or, but since the two container have the same P,V, AND T they have the same number of moles since

PV =nRT

SO

the weight of the gas in the second container divided by its molar mass =

0.123

or

2.99/? = 0.123

so

? = 2.99/o.123 = 24.3

Answer:

C. it involves the sharing of electrons

Explanation:

A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

Answer:

The Bohr Model is a planetary model in which the negatively-charged electrons orbit a small, positively-charged nucleus similar to the planets orbiting the Sun (except that the orbits are not planar). The gravitational force of the solar system is mathematically akin to the Coulomb (electrical) force between the positively-charged nucleus and the negatively-charged electrons.

Main Points of the Bohr Model

Electrons orbit the nucleus in orbits that have a set size and energy.

The energy of the orbit is related to its size. The lowest energy is found in the smallest orbit.

Radiation is absorbed or emitted when an electron moves from one orbit to another.

Have a great day friend! :D

A small positive charges nucleus is encircled by revolving negatively charged electrons in fixed orbits, according to the Bohr Atomic model.

The atom is basically depicted in the Bohr model as a central nucleus containing protons along with neutrons, with electrons in circular orbitals at various distances from the nucleus.

These orbits combine to form electron shells or energy levels, which allow you to see how many electrons are in each shell.

He concluded that electrons have more energy when they are located away from the nucleus, whereas electrons have less energy when they are located near the nucleus.

He was unable to explain the specifics of the Hydrogen and Helium atomic spectrums.

He did not explain how spectral lines split in the presence of a magnetic field. He did not explain the intensity of spectral lines.

Thus, these can be concluded regarding the Bohor's atomic model.

Explanation:

mostly it used in movies in the crime scence

Accelerants are flammable solvents such as kerosine, turpentine, gasoline etc. Therefore, the accelerant obtained from the crime scene here, is gasoline.

Accelerants are substances that can combine, blending, or disturb another substance, causing the speed of a natural or artificial chemical process to increase. Accelerants are important in chemistry because they can speed up most chemical reactions.

Accelerants change a chemical bond, accelerate a chemical process, or restore organisms to homeostasis. Accelerants are not always catalysts because they can be consumed by the process.

Flammable gases or solvents such as gasoline, diesel, butane gas, kerosine, turpentine etc are examples of accelerants. Therefore, among the given substances , gasoline is the accelerant.
