precipitates result from the exchange of positive and negative ions between reacting solutions of two ionic compounds. Thus‚ in this example the precipitate must be either silver chloride‚ AgCl or sodium nitrate‚ NaNO3. Sodium nitrate dissolves readily in water and is therefore soluble. Thus we can conclude that silver chloride is the insoluble precipitate. We can represent the formation of this precipitate by a net ionic equation: Ag+ +NO3 ̄ +Na++Cl ̄→AgCl+NO3 ̄+Na+ Net: Ag+ (aq)+Cl ̄ (aq)→AgCl(s) Ions

Constituent Assembly-2: I am ready to Vote As a first time voter‚ I am pretty much excited and confused about the upcoming CA election. Excited because I am voting for the first time and my single vote would elect someone who would one day draw the future of Nepal. I would want to thank the Election Commission for accepting the proposal from the political parties to extend the registration deadline by a week because it helped me to enroll my name in the list‚ which grants power to overthrow or

Oh Mary: A moving narrative about my deceased grandmother‚ Mary. Losing a best friend is the worst kind of feeling in a lifetime‚ is it not? On September 28th‚ 2008 I had lost my grandma due to cervical cancer. Her name was Mary Theresa Hammond and she was seventy-three years old when she had passed away. She was the only person in my life who loved me‚ cared about me‚ and understood me and much as she did. Nobody has ever been closer to my heart than she once was. The relationship between us was

Short Essays on Thermodynamics 1. The two ways of transferring heat are Conduction and Radiation: Heat conduction‚ also called diffusion‚ is the direct microscopic exchange of kinetic energy of particles through the boundary between two systems. When an object is at a different temperature from another body or its surroundings‚ heat flows so that the body and the surroundings reach the same temperature at thermal equilibrium. Conduction happens in both fluids and solids. Thermal radiation‚

The two studies by Dehaene-Lambertz‚ Dehaene‚ and Hertz-Pannier (2002)‚ as well as‚ Homae‚ Watanabe‚ and Taga (2014) will be compared. The studies measure the perception of speech sounds in the infant brain using functional magnetic resonance imaging (fMRI). Each set of researchers collected data from young infants around 3 months. Different qualities of sound were presented to the infants in order to measure the activation of certain structures in the brain. The hemodynamic responses to different

The first law of thermodynamics states that a certain energy balance will hold when a system undergoes a change of state or a thermodynamic process. But it does not indicate whether that change of state or the process is at all feasible or not. It is the second law of thermodynamics which provides the criterion as to the probability of various processes through the statements of Clausius that ‘’Heat does not pass from a body at low temperature to one at high temperature without an accompanying change

FACTORS AFFECTING SOLUBILITY There are three main factors that control solubility of a solute. (1) Temperature (2) Nature of solute or solvent (3) Pressure EFFECT OF TEMPERATURE Generally in many cases solubility increases with the rise in temperature and decreases with the fall of temperature but it is not necessary in all cases. However we must follow two behaviours: In endothermic process‚ solubility increases with the increase in temperature and vice versa. For

A Successful Celebration of CAS Week February 11-15‚ 2013‚ CAS week was held. Every society had their own booth. There was also a mini “perya” which was prepared by the Supreme Student Council (SSC). Every student was so excited about it‚ most especially the CAS students. The event was open not only for the students of the said department but for every student‚ faculty and staffs of the university who wants to witness the long week celebration of the CAS department. Everyone enjoyed and visited
