On the basis of hydrogen bond explain the anomalous behaviour of water when it freezes?
Anomalous expansion of water takes place because when water is heated to 277K hydrogen bonds are formed. Though ice is supposed to expand when it is converted into water, this gradual formation of hydrogen bonds causes it to contract, i.e. the contraction caused due to the formation of hydrogen bonds is greater than the actual expansion of ice. At 277K water has the maximum density because all the hydrogen bonds are formed by 277K beyond which water obeys the kinetic theory of molecules, an increase in volume when heated and the reverse when cooled. The same thing happens in the reverse when water is cooled beyond 277K. I think this should be the answer of this question
The hydrogen side of a water molecule is?
The hydrogen side of a water molecule has a slight positive charge.
A dynamic equilibrium is reached when hydrogen cyanide acid is dissolved in water Which species is present in the highest concentration in this solution?
C2H3O2-(aq) H+(aq) H3O+(aq) OH-(aq) HCN(aq)Those are the choices that could be given, but the answer is HCN. It can't be H+ or OH- because the water is de-ionized and H3O+ is not possible.
What gases are released following the electrolysis of water?
Hydrogen and Oxygen. A simple experiment shows this reaction. two graphite rods placed in a glass of water attached to a battery will split water into their individual elements. Be careful as these are combustible!! Also you are playing with electrity and water. However upon reaction they turn back into water. This has been deemed the cleanest fuel which can be created for this very reason.
Is there any solid that water cannot dissolve?
I would a non reactive transition metal such as gold Gold will dissolve in water if certain salts are already in solution (there is more gold dissolved in the waters of the oceans than has been mined on land), cyanide heap pile leaching gold ore concentrating works this way. Large piles of crushed gold ore are placed on a giant plastic sheet (to catch the concentrated gold and keep the cyanide out of the environment), drip lines on the top of the pile supply a continuous flow of potassium cyanide in water solution while a sump system at the bottom catches the spent solution for reuse, the cyanide solution readily dissolves gold from the top of the pile and releases it near the bottom where the solution pools and the concentration of gold gets too high to remain in solution, after a few decades the cyanide circulation system is turned off and the heap excavated, top layers are hazardous waste, bottom layer is sent to gold smelter.
What compound is formed when hydrogen is burnt?
When hydrogen burns, water is formed.
How do yu make cyanide?
Cyanide is usually made using ammonia, methane, and oxygen with a platinum catalyst. 2CH4 + 2 NH3 + 3O2 --> 2HCN + 6 H2O The cyanide is in the form of hydrogen cyanide, which is liquid at room temperature, but will readily become a gas. The common solid, water-soluble forms of potassium cyanide (KCN) and sodium cyanide (NaCN) are made by reacting hydrogen cyanide with the corresponding hydroxide in water. For example: KOH + HCN --> KCN + H2O.
What is a type of molecule that interact with water by dissolving in water and or forming hydrogen bonds with water molecules?
hydrophilic
Which type of bond is formed by ionic solids dissolving in water?
Ionic
How is limewater formed?
Lime water is a solution of sodium hydroxide. Lime water is formed by dissolving calcium oxide, CaO or quicklime in water.
How were the Florida cavern formed?
The Florida Caverns are limestone caves and were formed by rain water dissolving the limestone.
What is broken down and formed in the decomposition of water?
Hydrogen and Oxygen are the two elements that are formed when water decomposes.
Does a solution formed from the dissolving of sugar in water conduct electrcity?
No, because it is not ionic.
List six components of earths early atmosphere?
water, hydrogen cyanide,hydrogen sulfide, nitrogen, carbon dioxide, and carbon monoxide
If a mixture was formed by dissolving salt in water how could you get the salt back from the mixture?
evaporate it
What is Hydro Cyanide?
Hydrocyanic acid, or hydrogen cyanide is a chemical compound with the formula HCN. It is a gas and a weak acid. HCN and it's salts including sodium cyanide (NaCN) and potassium cyanide (KCN) are extremely toxic.
What is formed when burning hydrogen in air?
water
