Compound B is an ionic compound as it is hard,brittle and conducts electricity.
What is an ionic compound?Ionic compound or electrovalent compound is a type of compound which is formed between two elements when there is an exchange of electrons which takes place between the atoms resulting in the formation of ions.
When the atom looses an electron it develops a positive charge and forms an ion called the cation while the other atom gains the electron and develops a negative charge and forms an ion called the anion.
As the two atoms are oppositely charged they attract each other which results in the formation of a bond called the ionic bond.They are hard, malleable, ductile and good conductors of heat and electricity.They have high boiling points.

Answers
Answer:
What are some things that might happen that can change our air so that it is not health for plants?
Explanation:
Air pollutants have a negative impact on plant growth, primarily through interfering with resource accumulation. Once leaves are in close contact with the atmosphere, many air pollutants, such as O3 and NOx, affect the metabolic function of the leaves and interfere with net carbon fixation by the plant canopy. Air pollutants that are first deposited on the soil, such as heavy metals, first affect the functioning of roots and interfere with soil resource capture by the plant.

Why alcohol is weaker acid than water
Answers
Answer:
ACIDS ARE WEAKER THAN WATER
Explanation:In general, alcohols are weaker acids than water because the OH group in alcohols is less polar than the OH group in the water. The electron releasing nature of the R group in alcohols decreases the polarity of the OH bond, which in turn decreases the acid strength of alcohols.

D. Acid rain reacting with limestone bedrock.
Explanation:
- Brief Description:
A chemical reaction occurs when acidic rainfall falls on limestone or chalk. During the process, new, soluble compounds are produced. These disintegrate in the sea and are washed away, weathering the rock. Some forms of rock are resistant to chemical weathering. When rain falls from the sky onto a limestone (CaCO3) statue, a reaction between sulphuric acid and calcium carbonate happens. Calcium sulfate is formed as a result of this process (CaSO4). Because calcium sulfate is soluble in water, the statue will ultimately disintegrate. Limestone is chemically worn through the carbonation process. Rainwater collects carbon dioxide as it travels through the atmosphere, forming a weak carbonic acid. Water and carbon dioxide react to generate a mild carbonic acid. The fractures in the limestone are acted upon by this mild carbonic acid. Many weak acids, such as carbonic acid, are found in water. When carbon dioxide gas from the atmosphere combines with rainfall, a weak but copious acid is created. Other forms of acid rain are produced by sulfur dioxide and nitrogen gases, which function as chemical weathering agents.- Chemical WeatheringChemical weathering is generally the most active and effective weathering process. Water within soil or stone dissolves minerals of soil, softens minerals that absorpb the water, and dissolves carbondioxide.Chemical weathering is the breakdown of rock by chemical processes. Water, air, and chemicals released by organisms cause chemical weathering of rocks when they dissolve the minerals in a rock.- Carbon Dioxide-Bicarbonate-Carbonate Equilibrium
The carbon dioxide/bicarbonate/carbonate buffer is an essential buffer in surface waters. When water is in equilibrium with both CO2 from the atmosphere and carbonate-containing rock, its pH is buffered to 8.3, which is close to the pKa of the weak acid bicarbonate HCO3- (pKa = 8.4).- Acid Rain The production of nitric and sulfuric acids in our atmosphere causes acid rain. These chemicals are strong acids that are very soluble in water and dissolve in cloud water droplets.The majority of nitrogen and sulfur oxides are caused by human activity. Electric utilities (60 percent), industrial combustion (17 percent), and industrial processes are the principal sources of sulfur dioxide emissions (8 percent ). Transportation, with internal combustion engines, accounted for more than half of all NOx emissions, with additional emissions from electric utilities (26 percent) and industrial combustion accounting for the remainder (14 percent ). Agricultural operations, particularly manure management, are the biggest source of ammonia emissions, but industry and transportation also emit some ammonia. Acid rain leads to the acidity of lakes and streams, as well as the degradation of trees at high elevations and vulnerable forest soils.- Effect of LimestoneCalcium carbonate, often known as [Ca][CO3], is a common mineral. One well-known form of calcium carbonate is limestone. Acids in acid rain increase calcium carbonate breakdown by interacting with the carbonate anion.This results in a bicarbonate solution. Because surface waters are in balance with atmospheric carbon dioxide, the concentration of carbonic acid, H2CO3, in the water remains constant.Because the minerals react with the excess acid, the presence of limestone and other calcium carbonate rock in lakes and streams helps to maintain a steady pH. However, acid rain can finally overwhelm the surface water's buffering ability.different between larva of a silk work and larva of a bee

Why is the right side
of the periodic table
negative (gaining
electrons) and the
left side positive
(loosing electrons)?
Answers
Answer:
The elements on the left-side of the periodic table are relatively electron deficient. So due to their comparatively low effective nuclear charges (the net positive charge of the protons minus the shielding core electrons below the valence level), their electrostatic hold on these electrons are weak.
Elements further right on the period table though, have higher effective nuclear charges and stabilize electrons more effectively. Which leads to localized covalent bonding and the formation of molecules.
The right side contains non metals while the left side contains metals.
Metals lose electrons (negative electrons). They now have more protons, therefore making the ion positive.
Non metals gain electrons (positive electrons). So the ion has more electrons than protons which makes the ion negative.
