Outdoor air pollution: nitrogen dioxide, sulfur dioxide, and carbon MONOXIDE health effects.Explanation:Nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide are important ambient air POLLUTANTS. High-intensity, confined space exposure to NO2 has caused catastrophic injury to humans, including death. Ambient NO2 exposure may increase the risk of respiratory tract infections through the pollutant's interaction with the immune system. Sulfur dioxide (SO2) contributes to respiratory symptoms in both healthy patients and those with underlying pulmonary disease. Controlled human exposure studies have demonstrated that experimental SO2 exposure causes changes in airway physiology, including increased airways resistance. Both acute and chronic exposure to carbon monoxide are associated with increased risk for adverse cardiopulmonary EVENTS, including death. However, studies have not demonstrated a clear dose-dependent health risk response to increasing amounts of these pollutants except at high concentrations. In addition, a number of studies examining the effects of ambient level exposure to NO2, SO2, and CO have failed to find associations with adverse health outcomes.

because f be are do BONE LINEAR but h o o make covalent bond WITHIN themExplanation:F Be make sp2butH OO make sp3 paramiddle

it is LINK QUESTION VISIT through it

a covalent BOND is formed by SHARING a PAIR of ELECTRONS

NitrogenExplanation:Based on the periodic table, as you ascend the more ELECTRONEGATIVE it GETS. This is because of the electron shielding EFFECT. As you ascend up, there will be less electron shielding from the core and the electrons.

will LIQUIFY FIRST because it has HIGHER CRITICAL TEMPERATURE.

Solutions are HOMOGENEOUS in nature, meaning you cannot distinguish the solute and the solvent and they cannot be separated by physical means. In solutions that involve metal COMPOUNDS, the solution will be transparent, but will not be clear.Explanation:please MARK it as BRAINLEST answer

Ion(Na+) is more reactive. Moreover, Na(Sodium) isn't even reactive because this smybol shows that Sodium is in OCTET configuration and is stable. Hence, it is reactive and will lose 1 electron to BECOME stable. Since, it's outermost shell is full, it has attained stable configuration.hope this helps you PLEASE mark the ANSWER as brainlest please FOLLOW me

Option (3)EXPLANATION: Atomic radius increases while MOVING down to the group in the periodic table. THEREFORE, size of RB > size of Cs. Atomic radius of element decreases while moving left to right in the periodic table.Hence, answer is verified.

NO: Nitric oxideNO 2 : Nitrogen DIOXIDE gas; It has a REDDISH BROWN colour.Therefore, equation is 2NO+O 2 ⟶2NO 2 .

nt to make an amendment to my original answer as I got it wrong. If the electron hops into d(z2) and pairs with the electron already in there, that leads to additional shielding of the positive metal from the attraction of the negative l (in this theory we assume the metal to be POSITIVELY charged and ligands to be negative). That shielding, relative to the shielding provided by the SINGLE electron in d(x2-y2), leads to the z ligands being pushed further from the metal. That means the z ligands are further from the z electrons and repel them less. That stabilises the z electron, hence Jahn Teller effect. Same arg for d(x2-y2).The IMPORTANT thing is that Cu(II) is d9, Cu(I) is D10. Since there is no Jahn Teller effect in Cu(I), no stabilisation occurs, so Cu(II) is more STABLE.

In ATOM electrical stability means that BALANCED nucleus does not contain excess energy . if force between NUTRON i.e. no CHARGE and PROTON i.e. positive charge are unstable then the atom is unstable.Explanation:

Blue LIGHT is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it TRAVELS as shorter, smaller waves. This is why we SEE a blue sky most of the time. ... Also, the surface of Earth has reflected and scattered the light.Hope its help. please mark it as BRAINLIEST answer.

The “LATENT heat of evaporation” is the heat required to change a liquid into a vapor. ... The heat is now locked in the AIR as HUMIDITY (water vapor) without changing the temperature of the air. When the the heat is released, (like when the humid air touches a cold air mass) the water vapor condenses back into a liquid.Explanation:KINDLY mark it as brainlest answer

tion:The National Defense Authorization Act of 1996 amended Section 312 of the Federal WATER Pollution Control Act (also known as the Clean Water Act (CWA)) to REQUIRE that the Secretary of Defense and the Administrator of the ENVIRONMENTAL Protection Agency (EPA) develop uniform national discharge standards (UNDS) for vessels of the Armed Forces for “...discharges, other than sewage, incidental to normal operation of a VESSEL of the Armed Forces, ...” [Section 312(n)(1)]. UNDS is being developed in three PHASES. The first phase (which this report supports), will determine which discharges will be required to be controlled by marine pollution control devices (MPCDs)—either equipment or management practices. The second phase will develop MPCD performance standards.

here is ur answerExplanation:The human digestive SYSTEM CONSISTS of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, PANCREAS, liver, and gallbladder). Digestion INVOLVES the breakdown of food into smaller and smaller components, until they can be ABSORBED and assimilated into the body. The process of digestion has three stages. The first stage is the cephalic phase of digestion which begins with gastric secretions in response to the sight and smell of food. This stage includes the mechanical breakdown of food by chewing, and the chemical breakdown by digestive enzymes, that takes place in the mouth.Mark as brain list plzz
