n Notes on Carbon and its Compounds Two or more elements combine to form compound. There are two types of compounds- Organic Compound and Inorganic Compounds. Organic compounds are the one which are made up of carbon and hydrogen. Covalent Bond The bond formed by sharing a pair of ELECTRONS between two atoms are known as Covalent Bond. Carbon forms covalent bond. Carbon exists in two forms- as free state and as combined state. Free form of carbon is found in graphite, diamond and fullerene. In combined state, carbon exists as Carbon-dioxide, Glucose, Sugar ETC. Allotropes of Carbon Different forms of an element that has same chemical properties but different physical properties are known as Allotropes. There are three allotropes of carbon- diamond, graphite and fullerene. Diamond Diamond exits as three-dimensional network with strong carbon-carbon covalent bonds. Diamond is hard in nature with high melting point. It shines in presence of light and it is a bad conductor of electricity. The most common use of diamond is in making jewellery. It is also used in cutting and drilling tools. Graphite Graphite is made from weak van der wall forces. Each carbon atom is bonded with other three carbon atoms in order to form hexagonal rings. It serves as good conductor of heat and electricity. It is used as dry lubricant for machine parts as WELL as it is used in lead pencils. Fullerene It is a hollow cage which exits in the form of sphere. Its structure is similar to fullerene. But along with hexagonal rings, sometimes pentagonal or heptagonal rings are also present. Two Important Properties of Carbon CATENATION and tetravalency are the two important properties of carbon. Catenation is a property of carbon by which carbon atoms can link one another via covalent bond and can form long CHAINS, closed ring or branched chains etc. Carbon atoms can be linked by single, double or triple bonds. Carbon has a valency of 4 due to which it is known to have tetravalency. Due to this one carbon atom can bond with other 4 carbon atoms, with other atoms also such as Oxygen, Nitrogen etc. Hydrocarbons Compounds which are made up of carbon and hydrogen they are known as Hydrocarbons. There are two types of hydrocarbons found - Saturated Hydrocarbons and Unsaturated Hydrocarbons. Saturated Hydrocarbons consist of single bonds between the carbon atoms. For Example, Alkanes. Alkanes are saturated hydrocarbons represented by a formula, CnH2n+2. Unsaturated Hydrocarbons are the one with double or triple bonds between the carbon atoms. For Example, Alkenes and Alkynes. Alkenes are represented as CnH2n whereas alkynes are represented as CnH2n-2. Some saturated hydrocarbons and unsaturated hydrocarbons are represented as -

When EXHALED AIR is blown through Lime Water which is also known as CALCIUM hydroxide, the carbon dioxide present in the exhaled air reacts with the Lime water and turns it into a milky solution, since the the CO2 reacts with Ca(OH)2 and FORMS CaCO or Calcium CARBONATE, which is insoluble and white in colour.hope this helps you stay blessed ❣️

This means that the acid is classified on the basis of their source or ORIGIN. They are mainly of TWO types: Organic acid and Mineral acid. Organic Acid: This is the acid obtained from organic materials such as plants and animals. For e.g. CITRIC acid (Citrus FRUITS), Acetic acid (Vinegar), Oleic acid (Olive oil), etc.

Here's Your Answer Explanation:Glass is actually an INSULATOR. It doesn't ALLOW the flow of electrons easily from atom to atom, as seen in substances like copper, and other metals which are excellent conductors of both heat and electricity. Insulators have electrons that are held tightly which means they aren't shared between other atoms.Wood is a natural insulator DUE to air pockets within its cellular structure, which means that it is 15 times better than masonry, 400 times better than steel, and 1,770 times better than aluminum. In addition, lightweight wood framing methods allow easy installation of additional fibre or foil insulation.

Risk for chromosome problems The CHANCE of having a child with Down syndrome increases over time. The risk is about 1 in 1,250 for a WOMAN who CONCEIVES at age 25. It increases to about 1 in 100 for a woman who conceives at age 40. The risks may be higher.Explanation:

A bomb is an explosive weapon that uses the exothermic reaction of an explosive MATERIAL to provide an extremely sudden and violent release of energy. Detonations inflict damage PRINCIPALLY through ground- and atmosphere-transmitted mechanical stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects.[1] Bombs have been utilized since the 11th century STARTING in EAST Asia. A bomb is an explosive weapon that uses the exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy.

CExplanation:Any CHEMICAL reaction includes formation of transition STATE between reactant and product. Formation of transition state requires high energy content of reactant molecules for alignment of reacting groups, formation of transient UNSTABLE charges, rearrangements of chemical bonds etc. The energy required for formation of transition state is termed as activation energy. Enzymes enhance the rate of reaction by lowering down the activation energy of transition state.  In given graph, energy of substrate is higher than that of product REFLECTING the endothermic nature of reaction. And B is the activation energy in absence of enzyme which is lowered down to A in presence of enzyme. Therefore, the correct answer is OPTION C.

Iᑕ彡Plastic is a non-biodegradable synthetic material which is toxic. WIDELY dumped plastic is consumed as food materials by animals, such as cows. This consumption of the disposed of plastic leads to various health problems. Plastic CONTAINS toxins; when it is burning, the fumes that are released are harmful, if inhaled.WASTE plastic bags are polluting the land and water immensely. Plastic bags have become a threat to the life of animals living on earth as well as in water. Chemicals released by waste plastic bags enter the SOIL and make it infertile. Plastic bags are having a negative IMPACT on human health.

ot always possible to determine what genes an organism is CARRYING by simply looking at its appearance. After all, gene expression is a complex process that is dependant on many environmental and hereditary factors. For example, Gregor Mendel's experiments with pea PLANTS showed how dominant traits can mask recessive ones, thus causing him to muse how "rash it must be... to draw from the external resemblances of hybrids conclusions as to their internal nature" (Mendel, 1866).TODAY, scientists use the word "phenotype" to refer to what Mendel termed "external resemblance" and the word "genotype" to refer to an organism's "internal nature." Thus, to restate Mendel's musing in modern terms, we cannot infer an organism's genotype by simply observing its phenotype. INDEED, Mendel showed that phenotypic traits can be hidden in one generation, yet reemerge in subsequent generations. This occurs because some alleles are dominant over others, which means that their phenotype will mask the phenotype ASSOCIATED with the recessive alleles.

Hi pls make me as brainalist okayExplanation:Ice floats in water with about nine tenths of its volume submerged. What is the fractional volume submerged for an iceberg floating on a fresh water lake of a planet whose gravity is ten time that of the Earth’s?Make your LIL’ ONE defeat 3 deadly diseases with DTP* booster.In order to float an object must displace enough volume of water to match its mass. ASSUMING a uniform density for both ice and water, that would meanM(ice) g= 9/10 V(ice)*ρ(water)*gM(ice)=V(ice)*ρ(ice) so we getVi*ρi*g= 9/10*Vi*ρw*g => ρi=9/10ρwNow on the other planet we’ll call the fractional submergence “x”Mi*10g=Vi*ρi*10g=9/10*ρw*Vi*10g= x*Vi*ρw*10g => x=9/10. It’s the same.Should we have expected this? Of course we should. Even though ice weighs 10 times more under the new gravity, so does the water it displaces. Buoyant force is PROPORTIONAL to the weight of the displaced liquid. Weight means mass times acceleration of gravity. So in short the ice weighs 10 times more but it’s pushed up by a force 10 times strongergood night sweet dreamspurple u always
