HEY, pressy HERE IS YOUR ANSWER...Introduction MOLECULES—like the ones that make up your body—are just collections of atoms held together by CHEMICAL bonds. In many ways, they're a lot like Tinkertoy® building projects. In fact, if you take organic chemistry, you’ll most likely buy a model set that looks suspiciously similar to Tinkertoys®: Ball-and-stick model of the atom proline made using a modeling kit. Ball-and-stick model of the atom proline made using a modeling kit. _Image credit: "Proline model," by Peter Murray-Rust (CC BY-SA 2.5._ Just as you can put Tinkertoy® wheels together in different ways using different stick connectors, you can also put atoms together in a different ways by forming different sets of chemical bonds. The process of reorganizing atoms by breaking one set of chemical bonds and forming a new set is known as a chemical reaction. Chemical reactions Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products. An arrow is drawn between the reactants and products to indicate the direction of the chemical reaction, though a chemical reaction is not always a "one-way street," as we'll explore further in the next section. For example, the reaction for breakdown of hydrogen peroxide (\text{H}_{2}H  2 ​  H, start subscript, 2, end subscript\text{O}_{2}O  2 ​  O, start subscript, 2, end subscript) into water and oxygen can be written as: 2 \text{H}_{2}2H  2 ​  2, H, start subscript, 2, end subscript\text{O}_{2} \text{(hydrogen peroxide)}O  2 ​  (hydrogen peroxide)O, start subscript, 2, end subscript, left parenthesis, h, y, d, r, o, g, e, n, space, p, e, r, o, x, i, d, e, right parenthesis \rightarrow→right arrow 2\text{H}_{2}\text O \text{(water)}2H  2 ​  O(water)2, H, start subscript, 2, end subscript, O, left parenthesis, w, a, t, e, r, right parenthesis + \text{O}_{2}\text{(oxygen)}O  2 ​  (oxygen)O, start subscript, 2, end subscript, left parenthesis, o, x, y, g, e, n, right parenthesis In this example hydrogen peroxide is our reactant, and it gets broken down into water and oxygen, our products. The atoms that started out in hydrogen peroxide molecules are rearranged to form water molecules (\text{H}_{2}\text OH  2 ​  OH, start subscript, 2, end subscript, O) and oxygen molecules (\text O_2O  2 ​  O, start subscript, 2, end subscript). You may have noticed extra numbers in the chemical equation above: the 222s in front of hydrogen peroxide and water. These numbers are called coefficients, and they tell us how many of each molecule participate in the reaction. They must be INCLUDED in order to make our equation balanced, meaning that the number of atoms of each element is the same on the two sides of the equation. Equations must be balanced to reflect the law of conservation of matter, which states that no atoms are created or destroyed over the course of a normal chemical reaction. You can learn more about balancing reactions in the balancing chemical equations tutorial. Reversibility and equilibrium Some chemical reactions simply run in one direction until the reactants are used up. These reactions are said to be irreversible. Other reactions, however, are classified as reversible. Reversible reactions can go in both the forward and backward directions. In a reversible reaction, reactants turn into products, but products also turn back into reactants. In fact, both the forward reaction and its opposite will take place at the same time. This back and forth continues until a certain relative balance between reactants and products is reached—a state called equilibrium. At equilibrium, the forward and backward reactions are still happening, but the relative concentrations of products and reactants no longer change. Each reaction has its own characteristic equilibrium point, which we can describe with a number called the equilibrium constant. To learn where the equilibrium constant comes from and how to calculate it for a specific reaction, check out the equilibrium topic. When a reaction is classified as reversible, it is usually written with paired forward and backward arrows to show it can go both ways. For example, in human blood, excess hydrogen IONS (\text H^+H  Since this is a reversible reaction, if carbonic acid were added to the system, some of it would be turned into bicarbonate and hydrogen ions to restore equilibrium. In fact, this buffer system plays a key role in keeping your blood pH stable and healthy.HOPE IT WILL HELP, PRESSY...IF YOU LIKE THEN DON'T FORGET TO MARK IT AS THE BRAINLIEST...

☆♧HOPE THIS HELPS YOU MATE♧♡MARKS ME BRAINLIEST♡Raoult's law is a law of thermodynamics established by French chemist François-Marie Raoult in 1887. It states that the PARTIAL pressure of each component of an ideal mixture of liquids is equal to the VAPOUR pressure of the pure component multiplied by its mole fraction in the mixture. In consequence, the relative lowering of vapour pressure of a DILUTE solution of NONVOLATILE SOLUTE is equal to the mole fraction of solute in the solution.

what is X............

It neither electrophillic addition nor nucleophillic addition. Its actually Homolytic fission because when REACTION is done in the PRESENCE of metal as catalyst then the BOND is broken into free RADICALS not in cation or ANION.

system DESIGNED to capture waste heat from industrial smokestacks and turn it into electricity could significantly boost the efficiency of power stations, drastically cutting carbon emissions, its inventors claim. It could also reduce the amount of toxic pollution released into the atmosphere.The key to the efficiency of the heat-scavenging system is that it uses propane vapour RATHER than steam to turn a turbine and drive an electricity generator. This allows it to be driven by LOW-temperature waste heat.When steam is used to turn a generator, it must be pressurised and RAISED to around 650 °C. Below 450 °C, the process no longer operates EFFICIENTLY because the steam pressure drops too low. This means that the heat in flue gases below 450 °C cannot be used to generate electricity, and so is lost to the atmosphere.Scavenging electricity from smokestacks

Explanation:1. For a reaction : aA + bB → cCGram equivalence of A = Gram equivalence of B = Gram equivalence of C2. So, Gram equivalence of Acid = Gram equivalence of Base Given massEquivalent massof Acid = Given massEquivalent massof base3x=240x= 3×402=60________________________No. of gram EQUIVALENTS of BASE = No. of gram equivalents of ACID. Therefore, 2/40 = 3/X x = 3.20 x = 60. Hence the equivalent weight of the substance is 60.
