Answer:
Electron shielding
Explanation:
Ionization energy decreases moving down a group in the periodic table because of a phenomen known as Electron shielding, in which valence electrons do not interact with the positively charged nucleus as strongly as inner electrons do, because these inner electrons shield the valence electrons. This means it's easier for these valence electrons to leave the atom the more inner electrons are between them and the nucleus, this translates into a decreased ionization energy value.

For example,
C + O₂ ---------> CO₂
12g + 32g ---------> 44g
In this reaction the total mass of reactant (44g) is exactly equal to the mass of product (44g).
So, keeping the law of conservation of matter it is important to have a balanced chemical equations.

Answer: The temperature of 0.6 moles of fluorine that occupy 15 L at 2,300 mmHg is 920 K
Explanation:
According to ideal gas equation:
P = pressure of gas = 2300 mm Hg = 3.02 atm (760mmHg=1atm)
V = Volume of gas = 15 L
n = number of moles = 0.6
R = gas constant =
T =temperature = ?
Thus the temperature of 0.6 moles of fluorine that occupy 15 L at 2,300 mmHg is 920 K
2.) No because hydrogen can only form these bonds with highly electronegative atoms.
3.) Yes because hydrogen can easily form bonds with atoms that have a neutral charge.

Further Explanation:
Intermolecular forces:
The forces that exist between the molecules are known as intermolecular forces (IMF). IMF includes both attractive as well as repulsive forces. They are electrostatic in nature and determine the bulk properties of the substances like melting and boiling points. Molecules are held in any substance due to these forces.
The various types of intermolecular forces are as follows:
1. Hydrogen bonding:
It is an attractive force that exists between hydrogen and more electronegative elements like N, O, F. It can either be intermolecular or intramolecular. Intermolecular hydrogen bonding is the one that occurs between different molecules. For example, the bond between HF and is an intermolecular hydrogen bond. Intramolecular hydrogen bonding occurs between various parts of the same molecule. Ortho-nitro phenol and salicylaldehyde show this type of bonding.
2. Ion-dipole forces:
It is an attractive force that occurs between an ion and a molecule consisting of a dipole. The force between and water molecule is an example of this force.
3. Ion-induced dipole forces:
It is an attractive force that occurs between an ion and a nonpolar molecule. It induces a dipole in the molecule, resulting in ion-induced dipole force. The bond between and oxygen molecule is an example of such kind of bond.
4. Dispersion forces:
Also known as London dispersion forces, van der Waals forces, instantaneous dipole-induced dipole forces. These forces exist between atoms and molecules. The forces that occur in molecule is a dispersion force.
(1) Hydrogen bond is the one formed between the highly electronegative atom and hydrogen. Although oxygen is a highly electronegative element, it also forms hydrogen bonds with hydrogen. But it there are also more electronegative elements, other than O that can form hydrogen bonds with hydrogen. So this statement (1) is incorrect.
(2) As is clear from the definition of hydrogen bonds, it is formed between highly electronegative elements (like F, O, and N) and hydrogen. So this statement (2) is correct.
(3) Hydrogen bonding is formed as the result of interaction between and an element that can induce a dipole in hydrogen. But neutral atom cannot induce any charge on hydrogen atom. So this statement (3) is incorrect.
(4) Hydrogen can form bonds with high electronegative elements and not with the weak electronegative elements. So the given statement (4) is incorrect.

No, hydrogen can only form these bonds with highly electronegative atoms. Therefore, the correct option is option 2.
When an electronegative atom is attracted to another electronegative atom nearby, a hydrogen atom that is covalently bound to a highly electronegative atom forms a hydrogen bond. This attraction results from variations in electronegativity values, which unbalances the distribution of electrons. While the electronegative atom acquires a partial negative charge, the electron-deficient hydrogen becomes weakly positively charged. The electromagnetic attraction between these partially positive and partially negative ions is known as a hydrogen bond, and it is quite powerful.
Therefore, the correct option is option 2.

The correct answer is False
Explanation:
A limiting factor refers to a condition that stops or limits the growth of a population of any species. Some of these factors include the availability of sources such as food, shelter or water; predation; natural weather conditions; natural disasters; and competence.
The previous idea implies food is not the only factor or condition that would stop or limit the growth of a population but there are many other factors that could prevent a population from growing too large, this includes abiotic factors (nonliving condition) such as weather and biotic factors (living condition) such as competition with other species or individuals or predation.
Food is not the only limiting factor that keeps populations from growing too large. This statement is false.
Populations are regulated by a variety of factors, including but not limited to food availability. These factors can be categorized into two main types: density-dependent and density-independent factors.
Density-dependent factors are influenced by population size and include factors such as competition for resources (including food), predation, disease, and territoriality.
As a population grows, competition for limited resources, including food, increases. This can lead to reduced growth, increased mortality, and ultimately limit the population's size.
Thus, while food availability is an important factor in population dynamics, it is not the sole limiting factor. Other ecological factors and interactions within the ecosystem play significant roles in regulating population size and preventing populations from growing too large.
