What else can I help you with?
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.
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 is positively charged. This is because the oxygen atom in water is more electronegative than hydrogen, causing the electrons to be closer to oxygen, leaving the hydrogen atoms with a slight positive charge.
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.
What does hydrogen transform into when it is burned?
When hydrogen is burned, it transforms into water vapor.
Which acid is formed by dissolving hydrogen?
Hydrogen ions in water combine with water molecules to form hydronium ions (H3O+). This is the acid that is formed by dissolving hydrogen in water.
What is the pH of cyanide?
The pH of cyanide is about 6.4 in water. Cyanide is a weak acid and dissociates partially in water to form hydrogen cyanide (HCN) and cyanide ion (CN-).
Why is HCN soluble in water?
HCN is soluble in water because hydrogen cyanide can form hydrogen bonds with water molecules due to its polar nature. These interactions help break the hydrogen cyanide molecules apart and allow them to become distributed and dispersed throughout the water, increasing its solubility.
What are the acids in the following equilibrium reaction cn- plus h2o hcn plus oh?
The acid in the reaction is hydrogen cyanide (HCN), which is formed when cyanide ion (CN-) reacts with water (H2O) to release hydroxide ion (OH-).
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 compound is formed when hydrogen is burnt?
When hydrogen burns, water is formed.
What is a type of molecule that interact with water by dissolving in water and or forming hydrogen bonds with water molecules?
hydrophilic
What does it produce if you add Potassium cyanide and water?
When potassium cyanide is added to water, it dissolves and forms a highly toxic solution of potassium cyanide. This solution releases hydrogen cyanide gas, which is extremely poisonous. Mixing potassium cyanide with water can be hazardous and should be done with caution.
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.
Is carbonic acid a hydrocarbon?
No, carbonic acid is not a hydrocarbon. It is a weak acid formed from carbon dioxide dissolving in water. Hydrocarbons are compounds made up of hydrogen and carbon atoms only.
How were the Florida cavern formed?
The Florida Caverns are limestone caves and were formed by rain water dissolving the limestone.
