In this article, I will answer that very question as well as some other questions that may arise.So, does brass rust? The straight answer is no. Brass does not rust. Rust usually takes place due to the reaction of the metal inside the alloy and the environment around it. Brass does not have the required metal in it to produce rust. So, it does not rust. However, brass undergoes tarnishing due to oxidation and forms a blackish, greenish layer on its surface....

Playing with balloons is one of the fondest memories of all of our childhood.So tell me, if you fill a balloon with water and another balloon with air and throw them both in water, what would happen?Obviously, the water-filled balloons will sink while the air-filled balloon will float.So, why exactly did this happen? Let’s find out….So, does density affect weight? Yes, density affects weight but, under specific conditions. The density of an object is directly proportional to its mass and inversely proportional to its volume....

I am sure you are not expecting a good odor from this gas! Well yes, you are right, hydrogen sulfide gas smells like rotten eggs!!The molar mass of H2S is 34.08 g/mol and its density is 1.363 g dm-3. The melting point and boiling point of H2S are -82℃ and -60℃ respectively.H2S has a covalent bond because the sulfur atom completes its octet by sharing 2 electrons with 2 hydrogen atoms and thus forms a covalent bond....

Commonly known as “quicklime” or “burnt lime”, calcium oxide, a white crystalline compound, is one of the widely used chemical compounds. It is regarded as one of the oldest compounds known to mankind.The chemistry of calcium oxide is very interesting. At the same time, calcium oxide often confuses people with some of its properties and nature. One such aspect is the type of chemical bonding.Is calcium oxide ionic or covalent?...

So, Is Hexane Polar or Nonpolar? Hexane is nonpolar in nature because of its symmetric geometrical structure. Although Carbon and hydrogen have an electronegativity difference of 0.35, the dipole gets canceled out due to the symmetry making the C6H12 a polar molecule.It exists as a colorless liquid at room temperature with a boiling point of around 50-70 degrees Celcius.Hexane is prepared by the refinement of crude oil. It is widely used as a solvent in chemical laboratoriesIt is an alkane containing six carbon atoms chain....

Bromine is the third lightest of the halogens and can be found in the form of both a smoldering reddish-brown liquid at normal room temperature and a reddish-brown gas.Being in the same group as Fluorine, Chlorine, and Iodine, it exhibits similar chemical properties.The elemental Bromide is extremely reactive and therefore does not materialize freely in nature.In fact, it is available in the form of a soluble colorless halide crystalline mineral salt, like table salt....

Hypochlorite being a conjugate base of hypochlorous acid, readily reacts with different elements as it is an unstable chlorine oxoanion, monovalent inorganic anion, and chlorine oxide. Most of the hypochlorite salts exist as an aqueous solution as they cannot remain stable in other states of matter.Hypochlorite (ClO) is toxic for human beings because it is a strong irritant to the olfactory system and affects the mucous membrane to reduce the perception of a smell....

In ionic form chlorine dioxide is known as chlorite with the molecular formula (ClO2-). It is clear from the chemical formula that chlorine dioxide or chlorite is a strong oxidizing agent.Chlorine dioxide tends to get reduced and provide oxygen to different substrates during an oxidation-reduction or redox reaction.From this, it can be understood that chlorine dioxide in an ionic state will be a strong oxidizer of chlorine oxyanions.Recently, this compound was in limelight due to a fraudulent claim to cure coronavirus....

Pb is a silver-grey colored, soft, malleable, ductile, and heavy metal.It is obtained by roasting (heating in the absence of oxygen) mineral galena (PbS).Metals generally conduct electricity. In this article, we will find out if Lead also conducts electricity or not and the reason for the same.So, does lead conduct electricity? Pure Lead is a good conductor of electricity due to the presence of free electrons. However, Lead can be a bad conductor of electricity due to its reaction with atmospheric oxygen to form a layer of lead oxide which does not allow the electricity to pass through....

Now, the question is whether fusion is an exothermic or endothermic process? A fusion reaction is an exothermic process as energy is released. The mass of the product formed is less than the reactants, and consequently, energy is released; therefore, the reaction is exothermic. The fusion of lighter nuclei is an exothermic process, whereas fusion of heavier nuclei is an endothermic process. What is a Nuclear Fusion Reaction? Nuclear fusion is defined as the reactions in which two or lighter nuclei combine, resulting in heavier nuclei and subatomic particles (neutrons or protons) with the release of a great amount of energy....

Water is a polar liquid. It is commonly used as a solvent because of its properties of availability and affordability. Also, it is essential for human survival.In this article, we will understand the properties of a mixture formed by mixing these two entities- water and sugar and classify it based on uniformity in chemical composition.So, is sugar water homogeneous or heterogeneous? Sugar water is a homogeneous mixture as sugar completely dissolves in water, and we cannot distinguish between solid and liquid phases....

So, what is the ph of alcohol? The pH value of alcohol is 7.33. Alcohol cannot be defined as acidic or alkaline, rather defined as amphiprotic because the nature of the bond between carbon and hydroxyl group is non-ionic but slightly polar in nature. Aliphatic alcohol acts as a weak acid in presence of any strong base. Aromatic alcohols behave as weakly acidic at standard conditions because of the resonance allowing kicking off the hydrogen....

The melting and boiling point of silicon tetrafluoride is -95.0 °C and -90.3 °C and hence, it exists as a gas at room temperature.Silicon tetrafluoride is a colorless, toxic, corrosive, and non-flammable gas with a pungent smell. Silicon tetrafluoride is prepared in the laboratory by decomposition of BaSiF6 at a temperature greater than 300 °C.BaSiF6 —–> SiF4 (volatile) + BaF2 (residue)The volatile nature of silicon tetrafluoride limits their use and hence, it is restrained to only organic synthesis and microelectronic....

Another hint, owing to its high corrosion resistance and good hard tissue compatibility this metal is also used for making medical transplants.I hope you have guessed the answer by now. Yes, we are talking about “Titanium”.Titanium is the ninth most abundant element in the earth’s crust. It forms around 0.63% of the earth’s crust.It was originally called manaccanite as it was discovered in a village named Manaccan located in the South Cornwall of the United Kingdom by William Gregor, in 1791....

Every cell of the body contains its own DNA which is unique to every individual. The different individuals, even when they belong to the same species do not have identical DNA except for the congenital twins that are born with the same DNA.Due to its uniqueness DNA also serves as a source of identification. Most DNA is located inside the nucleus of a cell. However, another type of DNA called mitochondrial DNA which is maternally inherited is located in the mitochondria of the cell....

In this article, we’ll look at whether Hydrogen bromide (HBr) is an acid or a base.So is HBr an acid or base? Hydrogen bromide (HBr) is an acid because it dissociates into two ions as H+ and Br- in an aqueous solution. Any compound that releases protons in an aqueous solution is considered to be an acid. Moreover, as HBr completely dissociates in an aqueous solution it is regarded as the strong acid with a pH of 3....

Synthetically, it is produced as a product of the reaction between HCl and ammonia and also as a byproduct of the Solvay process.
