If y’all can me discuss and answer these questions in your own way, of course i have my own answers but i wanna add on to it,

1) The answer is: Ionic bond forms when an element (usually metal) give its extra electron(s) to an element (usually nonmetal) who needs it.  

For example compound magnesium chloride (MgCl₂) has ionic bond (the electrostatic attraction between oppositely charged ions).  

Magnesium (metal) transfers two electrons (form positive cation) to chlorine (form negative anion).  

2) The answer is: Ionic bond is the electrostatic attraction between oppositely charged ions (cations and anions).

Cations are positively charged ions, for example Na⁺, Ca²⁺.

Anions are negatively charged ions, for example Cl⁻, O²⁻.

The electrostatic attraction between the anions and cations leads to the formation of a solid with a crystallographic lattice.

3) The answer is: Ionic bond is stronger than other types of bonds.

For example, because ionic compounds have strong ionic bonds, they have higher melting points than compound with other bonds.

The melting point of solid is defined as the temperature at which the solid exists in equilibrium with its liquid under an external pressure of one atmosphere.

4) The answer is: charge and distance are the two factors that affect the strength of the ionic bond.

For example, calcium oxide (CaO) has stronger ionic bond than sodium chloride (NaCl), because two electrons are transferred.

Other example, sodium chloride (NaCl) has stronger ionic bond than potassium chloride (KCl), because shorter distance between cations and anions.

5) The answer is: metals from group 1 and 2 and nonmetals from group 16 and 17 are most likely to form ionic bonds.

For example:

Alkaline metals (group 1), in this example sodium, have lowest ionizations energy and easy remove valence electrons (one electron) and form cation.

Sodium electron configuration: ₁₁Na 1s²2s²2p⁶3s¹; one valence electron in 3s orbital.

Nonmetals chlorine from group 17 is far right in the main group and it has highest electron afinity, so gain one electron and form anion.

Electron configuration of chlorine: ₁₇Cl 1s² 2s² 2p⁶ 3s² 3p⁵; seven valence electrons 3s and 3p orbitals.

6) The answer is: Ionic compounds have high melting point and good conductivity.

Ionic compounds conduct electricity, because it dissociate in ions and ions conduct electicity.

Ionic substances dissociate in water on cations and anions. For example, dissociation of potassium chloride in water: KCl(aq) → K⁺(aq) + Cl⁻(aq).

Ionic compounds (most of the salts, strong acids and bases) dissolve in water because an ion-dipole interactions.

An ion-dipole is electrostatic interaction between a charged ion (cations and anions) and a molecule that has a dipole (in this example water).  

Dipole is a separation of positive and negative charges. In water, hydrogen has positive and oxygen has negative charge.  

7) The answer is: Na⋅↷⋅Cl: → [Na⁺] + [:Cl:⁻].

In this example, sodium (Na) gives valence electron to chlorine (Cl).

Sodium is a metal with 11 electrons, it gives one valence electron to gain stable electron configuration as noble gas neon (Ne).

Chlorine is nonmetal with 17 electrons, it gain one electron to gain stable electron configuration as noble gas argon (Ar).

Sodium form cation Na⁺ and chlorine form anion Cl.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

according to the u.s. department of agriculture, the label of "certified organic" comes with a set of highly regulated standards for environmental stewardship and resource conservation. some of these include maintenance and improvement of soil quality, prevention of ground and surface water contamination, greenhouse gas regulation, encouragement of biodiversity and conservation of water and energy (see references 1). organic practices integrate natural methods such as mulching, plant diversity, native and adapted plants, crop rotation and the introduction of beneficial insects to control pests without synthetic pesticides.

environmental implications of pesticides

synthetic pesticides ensure high crop yields. while effective in achieving this goal, pesticides contaminate soil, air, ground and surface water, as well as the plants and animals that come into contact with these contaminated sources. freshwater and marine organisms are particularly susceptible to pesticides through agricultural runoff. pesticides also reduce soil fertility (necessitating the use of synthetic fertilizers) and can travel far from the original source, contaminating water and air hundreds of miles from the location of application (see references 2).

health implications of organics

although a subject of particular debate, many recent findings show that organic food is healthier than conventionally grown food. according to the usda, an extensive european union-funded study found that organically grown foods contain more beneficial compounds, such as the vitamins and antioxidants needed to combat many diseases (see references 5). organic milk, meat and eggs are regulated to ensure they are free of hormones administered to conventional livestock and poultry.

health implications of pesticides

pesticides affect human health in three ways: through skin contact, inhalation and ingestion. acute and long-term exposure to pesticides can cause serious health problems for farmers who apply them. the majority of other people are affected by drinking contaminated water and eating contaminated marine life (see references 3). pesticides have been linked to neurological disorders, endocrine and reproductive disorders, immune system deficiencies and cancer. according to the world health organization, acute pesticide poisoning (app) is responsible for significant annual mortality, especially in developing nations (see references 4).

other important considerations

not every small farm or business owner can afford the costly certification process required to be considered "certified organic," even if the farm is not using chemicals. "transitional" farms include those that once used chemicals and are now transitioning to organic-only production. in addition, though organic farming methods offer obvious environmental benefit, an organic apple shipped from around the world creates a different set of environmental problems. locally grown food (particularly locally grown, organic food) is key in sustainable food production.
