The property of acids which would cause acid rain to damage buildings over time is:
Acids react with limestone.
The correct answer choice is option c.
This simply means that acids has this property which corrodes the surface they come in contact with especially stones.
One of those things which can be done to prevent acid rain damage to objects from metal and carbonate, such as limestone is coating the surface of the metal.However, this can be done by coating the surface of metals, or carbonate by coating it with other metals. By so doing, this can prevent acid rain damage to it.
That being said, by default, concentrated acids are highly corrosive.
Coating surfaces of metals can prevent acid rain damage to it
What is an acid?This refers to a substance which when dissolved in water, it produces hydrogen ion as the only positive ion in the solution.
So therefore, the property of acids which would cause acid rain to damage buildings over time is acids react with limestone.

christopher shaw et al., "aluminum vaccine adjuvants: are they safe?," current medicinal chemistry 18,
The most used vaccination adjuvant is aluminum, which has been shown to be a neurotoxic in experimental settings. But it is abundantly obvious from experimental research that aluminum adjuvants have the potential to cause significant immune problems in people.
What is Aluminum vaccine adjuvants?
Aluminum adjuvants have been used extensively for almost 90 years, yet medical research still has a very limited grasp of how they work. Concerning gaps in knowledge exist on the toxicity and pharmacokinetics of certain substances. Despite this, there seems to be widespread acceptance of the idea that aluminum in vaccinations is safe.
Adjuvant-form aluminum carries a risk for autoimmune, long-term brain inflammation, and associated neurological disorders and may therefore have substantial and widespread negative health effects. According to our assessment, the likelihood that vaccine benefits may have been exaggerated and the risk of potential adverse effects underappreciated has not undergone a thorough evaluation in the medical and scientific community.

To determine the standard heat of formation for carbonic acid, h2co3, the proper chemical equation is:_________
The standard heat of formation for carbonic acid, H₂CO₃, the right chemical equation is H₂CO₃ → H₂O + CO₂ (and also H+ and CO₃— but this is irrelevant here).
Carbonic acid reaction :An important example of a reversible reaction in the human body.
This reaction occurs when CO₂ (CO₂) and water (H₂O) combine to form carbonic acid (H₂CO₃).
The newly formed acid is unstable, and it dissociates to yield both proton (H+) and bicarbonate ion (HCO₃-). The equation for the entire carbonic acid reaction is: H₂CO₃ → H₂O + CO₂
Carbonic acid (H₂CO₃) forms in small amounts when CO₂ dissolves in H₂O, yet decomposes rapidly under ambient conditions of temperature and pressure. Despite its fleeting existence, H₂CO₃ plays a crucial role in the global carbon cycle and in biological carbonate-containing systems. The short lifetime in water and presumed low concentration under all terrestrial conditions has stifled study of this fundamental species.

Salts and polymeric substances frequently do not elute. Solvents: For adsorbent sites, the solvent will compete with the sample.The more polar the solute, the more readily it will dissolve in the stationary phase, remain in the column, and finally elute last.

How many electrons are transferred from glyceraldeyde 3 phosphate to nad in glycolysis?
Electrons transferred from Glyceraldehyde 3 phosphate to NAD in glycolysis per glucose are 4.
What are electrons?The electron is a subatomic particle (denoted by symbol e−or β−) whose electric charge is negative one elementary charge. Electrons belong to first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron's mass is approximately 1836 times smaller than that of proton.
Quantum mechanical properties of electron include an intrinsic angular momentum (spin) of a half-integer value, expressed in units of the reduced Planck constant, ħ. Being fermions, no two electrons can occupy same quantum state, in accordance with the Pauli exclusion principle. Like all elementary particles, electrons exhibit properties of both the particles and waves: They can collide with the other particles and can be diffracted like light. The wave properties of electrons are easier to observe with the experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a longer de Broglie wavelength for given energy.
Electrons play an essential role in numerous physical phenomena, such as electricity, magnetism, chemistry and thermal conductivity, and they also participate in the gravitational, electromagnetic and weak interactions. Since an electron has charge, it has a surrounding the electric field, and if that electron is moving relative to an observer, said observer will observe it to generate a magnetic field. Electromagnetic fields produced from other sources will affect the motion of an electron according to Lorentz force law.
Electrons radiate or absorb energy in form of photons when they are accelerated. Laboratory instruments are capable of trapping individual electrons as well as electron plasma by use of electromagnetic fields. Special telescopes can detect the electron plasma in outer space. Electrons are involved in many applications such as the tribology or frictional charging, electrolysis, electrochemistry, battery technologies, electronics, welding, cathode-ray tubes, photoelectricity, photovoltaic solar panels, electron microscopes, radiation therapy, lasers, gaseous ionization detectors and particle accelerators.
