tion:For burning to occur, the surface in contact with the AIR must be heated to its ignition TEMPERATURE. ... An iron rod will not burn as it has RELATIVELY very less surface area per UNIT mass but iron filings with more surface area per unit mass can burn in air and GET converted to iron oxide.

tion:Hydrogen peroxide is a chemical compound with the formula H2O2. In its PURE form, it is a very pale blue[5] liquid, slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic. Concentrated hydrogen peroxide, or "high-test peroxide", is a REACTIVE OXYGEN SPECIES and has been used as a PROPELLANT in rocketry.[6] Its chemistry is dominated by the O-O bond.

The NUMBER of ATOMS of calcium =0.25 GRAM atoms ×6.023×1023 atoms / G atom ≈1.50×1023 atoms.

Two hydrogen (H) atoms can ALSO bond with two oxygen (O) atoms, making the FORMULA H2O2. That's just one more oxygen than water, but it is a TOTALLY different compound. You can see that each of the Oxygen atoms has eight electrons, and the two HYDROGENS have two electrons each.please make it brainliest answer

chlorinethane is FORMED ALONG with HYDROCHLORIC GAS

The REASON of making USE of nylon in tooth brushes is that it is one of the earliest discovered PLASTIC materials which had the property to be made into fibers . ... EVEN today, nylon is majorly used as fibers due to its excellent mechanical STRENGTH and durability.

Because of its LOW solubility (as COMPARED to N2) in blood, a mixture of OXYGEN and helium is used in DIVING apparatus used by deep sea DIVERS.

Explanation:For indigestion people are advised to TAKE milk of magnesia i.e BASE which will nullify the acidity of our stomach.For ant's bite we will use baking soda which is a base as ant's bite has formic acid which can be nullified by baking soda.For soil we can use calcium HYDROXIDE if the soil has turned ACIDIC and we can use organic matter if the contents of soil is basic in nature. Hope it helps!!!!

any of five chemical SUBSTANCES that are not METALS and that combine with HYDROGEN to form strong ACID compounds from which simple SALTS can be made

Total area under the two curves is independent of moles of gas.This is because, the quantity on the Y axis INCLUDES the reciprocal of N.Thus, the area under the curve gives FRACTION of molecules and total area is constant.HENCE, the option A is correct.(B) The two areas are equal . Hence, the option B is correct.(C) T 1

For example, if the pressure in a system INCREASES, or the volume decreases, the equilibrium will shift to favor the side of the REACTION that involves fewer moles of GAS. Similarly, if the volume of a system increases, or the pressure decreases, the production of ADDITIONAL moles of gas will be favored.Explanation:GOOD afternoon, good day and luck.

Alkali saltsSodium hydroxide (NaOH) – often called "CAUSTIC SODA"Potassium hydroxide (KOH) – commonly called "caustic potash"Lye – generic TERM for either of two previous SALTS or their mixture.Calcium hydroxide (CA(OH)2) – saturated solution known as "limewater"

The muscular system is an organ system CONSISTING of skeletal, SMOOTH and cardiac muscles. ...There are three DISTINCT TYPES of muscles: skeletal muscles, cardiac or heart muscles, and smooth (non-striated) muscles.

As GIVEN,Eq. conductance of CH 3 COOH=369.3−101.7+71.7=339.3soα=14.3/339.3=0.041so hydrogen ion conc.=cα=0.01×0.041=4×10 −4

When an IDEAL gas expands into the vacuum it does zero work. Since the gas does not have to expend any internal ENERGY for the expansion, the term FREE expansion. Since there is no change in internal energy, the temperature of the ideal gas does not change on free expansion.Explanation:please mark me as BRAINLIEST

Solutions are nothing more than mixtures of different compounds or elements. You encounter solutions every day without even realizing it. Even the air you breathe-which contains water-is a solution of a liquid and a gas. If you drank a soda today, you actually drank of solution of a gas DISSOLVED in FLAVORED water. If you're wearing a bracelet made of sterling silver, you're wearing a solution of TWO metals. In this experiment, you'll be working with a liquid solution, which is ONE of three TYPES of solutions. The other types are gaseous solutions and solid solutions.Explanation:

tion:TRANSCRIPTION is the PROCESS by which the INFORMATION in a STRAND of DNA is copied into a new molecule of messenger RNA (mRNA). ... The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.

Crude oil is a naturally occurring, UNREFINED petroleum PRODUCT composed of hydrocarbon deposits and other organic materials. A type of fossil fuel, crude oil can be refined to produce USABLE products such as GASOLINE, DIESEL, and various other forms of petrochemicals.

Bohr's model of the hydrogen atom is based on three postulates: (1) an ELECTRON moves AROUND the nucleus in a CIRCULAR orbit, (2) an electron's angular momentum in the orbit is quantized, and (3) the change in an electron's energy as it makes a QUANTUM jump from one orbit to another is always accompanied by the ...

→ Structural isomers are molecules with the same MOLECULAR formula, but their atoms have different ARRANGEMENTS or bonds.→ For example : BUTANE and isobutane have the same NUMBER of carbon (C) atoms and hydrogen (H) atoms, so their molecular formulas are the same.
