Liquids are almost incompressible. In liquids MOLECULES are PRETTY close to each other. ...Liquids have fixed volume but no fixed shape. ...Liquids flow from higher to lower level.Liquids have their boiling POINTS above room temperature, under NORMAL conditions.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━Evaporation is a reversible physical reaction. The reverse process is water CONDENSING from the ATMOSPHERE ONTO a surface. Evaporation INVOLVES the change in state from liquid to gas. It's not the same as vaporization, or boiling, because it occurs at temperatures below the boiling point of the substance.━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

2NaOH+Cl ------ NACL+ NAOCL +H²O

hello.. Explanation:In classical mechanics, kinetic energy (KE) is equal to HALF of an object's mass (1/2*m) MULTIPLIED by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (V = 5 m/s), the kinetic energy is equal to 125 JOULES, or (1/2 * 10 kg) * 5 m/s2.hope you get your ANSWER plz follow me follow back will be done plz mark as brain list answer

for balancing the EQUATION u have to FIRST balance metal then nonmetal then metalloid and then oxygen.. .. and the question is that how should we know what are metals and nonmetal ?easy WAY to IDENTIFY metal and nonmetals is the substance with valancey 1,2,3 are metals and 4,5... 8 are nonmetals and there is only 8 valance electron metalloid are which carry both PROPERTIES of metals and nonmetals.... this is simple way for balancing equation

chemical reactionbalanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total CHARGE is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.balance equationA balanced chemical equation OCCURS when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side. In this chemical reaction, NITROGEN (N2) REACTS with hydrogen (H) to produce ammonia (NH3). The reactants are nitrogen and hydrogen, and the product is ammonia.Explanation:PLEASE mark as branlist

tion:1) The kinetic theory of matter (particle theory) says that all matter consists of MANY, very small particles which are constantly moving or in a continual state of motion. The degree to which the particles move is DETERMINED by the amount of ENERGY they have and their relationship to other particles2)Brownian motion, or pedesis, is the random motion of particles suspended in a medium. This pattern of motion typically consists of random fluctuations in a particle's position inside a fluid sub-domain, followed by a relocation to another sub-domain.3) Diffusion is the movement of a substance from an area of HIGH concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells. hope its helpfulmark my ans in brainlist

chemical REACTION is a process that leads to the chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation. Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur.The substance (or substances) initially involved in a chemical reaction are called reactants or reagents. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants. Reactions often consist of a sequence of individual sub-steps, the so-called elementary reactions, and the information on the precise course of action is part of the reaction mechanism. Chemical reactions are described with chemical equations, which symbolically present the starting materials, end products, and sometimes intermediate products and reaction conditions.Chemical reactions happen at a characteristic reaction RATE at a given temperature and chemical concentration. Typically, reaction rates increase with increasing temperature because there is more thermal energy available to reach the activation energy necessary for breaking bonds between atoms.Reactions MAY proceed in the forward or reverse direction until they go to completion or reach equilibrium. Reactions that proceed in the forward direction to approach equilibrium are often described as spontaneous, requiring no input of FREE energy to go forward. Non-spontaneous reactions require input of free energy to go forward (examples include charging a battery by applying an external electrical power source, or photosynthesis driven by absorption of electromagnetic radiation in the form of sunlight).Different chemical reactions are used in combinations during chemical synthesis in order to obtain a desired product. In biochemistry, a consecutive series of chemical reactions (where the product of one reaction is the reactant of the next reaction) form metabolic pathways. These reactions are often catalyzed by protein ENZYMES. Enzymes increase the rates of biochemical reactions, so that metabolic syntheses and decompositions impossible under ordinary conditions can occur at the temperatures and concentrations present within a cell.The general concept of a chemical reaction has been extended to reactions between entities smaller than atoms, including nuclear reactions, radioactive decays, and reactions between elementary particles, as described by quantum field theory.

The answer to this question is " IONIZATION". Ionization, is the PROCESS by which an atom or a molecule acquires a negative or POSITIVE CHARGE by gaining or losing electrons to form ions, often in conjunction with other CHEMICAL changes.

because FRACTIONAL distillation REQUIRES that the vapour presence of various components in the mixture be different but this is not so azeotropic .. For this reason ETHANOL cannot be completely purified by fractional distillation of Ethanol WATER mixture.

: RATE Law of an equation is an expression that shows the dependence of the rate of reaction on the concentration of the active masses.Assume a reaction Rate Law WOULD be : On the basis of steps in a reaction,there are CLASSIFIED into : ELEMENTARY Reaction : One step reactions Complex Reactions : Multiple step reactions If the given reaction is elementary,Here,The variables are equal to the stoichiometric coefficients If the given reaction is complex, Here,The variables may or may not be equal to the stoichiometric coefficientsSince there are multiple steps in complex reactions,the concentration of the reacting species is variable. As a result,the rate of the reaction is determined by slowest step termed as Rate Determining Step

Non-metals react with oxygen to FORM non-metal oxides. Non-metal oxides are ACIDIC in nature. If an element forms an acidic oxide,then the element will be a non-metal. Metal oxide are basic in nature and form BASES on dissolving in water.Explanation:Hopefully understandable ^-^.

I don't KNOW the ANSWER.............

t electron enters in the 5d sub-shell. But the outermost shell is 6th shell & the 6th shell has only 6s sub-shell. This 6s sub-shell has 2 ELECTRONS in it. Therefore MERCURY has 2 valence electrons. Since Mercury can DONATE this two 6s electrons, its valency is ALSO 2.Thus, Valency/valence electrons of Mercury is/are 2.
