What else can I help you with?
Does ammonia contain hydroxide ions?
No. Ammonia has the chemical formula NH3. However, when dissolved in water ammonia will form small amounts of ammonium hydroxide. NH3 + H2O --> NH4OH
What temperature does water disassociate?
Water dissociates into hydrogen ions and hydroxide ions in small amounts at room temperature, but significant dissociation occurs at higher temperatures. The exact temperature at which water dissociates into equal concentrations of hydrogen and hydroxide ions (neutral pH) is 25 degrees Celsius.
Does water react with sodium?
Yes, water reacts with sodium vigorously, producing hydrogen gas and sodium hydroxide. The reaction is highly exothermic and can lead to a release of large amounts of heat and potentially cause the hydrogen gas to ignite.
What causes potassium to catch fire?
Let's look at the equation for the reaction of potassium and water: Potassium + water --> potassium hydroxide + hydrogen The reaction is fast and generates sufficient heat (it is exothermic) for the hydrogen gas produced to react with oxygen in the air. The presence of potassium gives the flame a lilac colour as the hydrogen burns. In comparison, lithium and sodium are less reactive so the reactions are slower and produce less heat so the hydrogen gas produced does not ignite. So, the potassium does not burn, the hydrogen does!
What is the name given to the reaction of acid and alkali combined if mixed in the right amount?
The reaction of an acid and an alkali in the right amounts is called neutralization. In this reaction, the acid's hydrogen ions combine with the alkali's hydroxide ions to form water and a salt.
When water ionizes it produces equal amounts of hydrogen and hydroxide ions which can re associate with each other?
When water ionizes, it produces hydronium (H3O+) and hydroxide (OH-) ions, not equal amounts of hydrogen and hydroxide ions. These ions can indeed reassociate to form water molecules through a reversible chemical reaction.
What produces Large amounts of energy within the Sun?
Fusion of hydrogen.
What is occurring when a piece of potassium metal ignites in a beaker of water?
The potassium reacts with water to produce potassium hydroxide, hydrogen gas, and large amounts of heat. The heat ignites the hydrogen which in turn ignites the potassium.
Is amonium hydroxide a liquid metal?
Ammonium hydroxide is neither a metal nor a liquid. It is an compound consisting of the nonmetals nitrogen, hydrogen, and oxygen that only exists in small amounts in solutions of ammonia dissolved in water. The only liquid metal is mercury.
Does ammonia contain hydroxide ions?
No. Ammonia has the chemical formula NH3. However, when dissolved in water ammonia will form small amounts of ammonium hydroxide. NH3 + H2O --> NH4OH
What temperature does water disassociate?
Water dissociates into hydrogen ions and hydroxide ions in small amounts at room temperature, but significant dissociation occurs at higher temperatures. The exact temperature at which water dissociates into equal concentrations of hydrogen and hydroxide ions (neutral pH) is 25 degrees Celsius.
Why do you see flame in reaction between sodium and water?
The sodium an water react to produce sodium hydroxide, hydrogen gas, and large amounts of heat. This heat ignites the hydrogen which in turn sets the sodium on fire. Sodium burns with a yellowish flame.
When sodium is put in water it produces a golden flame why?
Metallic sodium reacts with water producing sodium hydroxide, hydrogen gas, and lots of heat. The hydrogen gas mixes with air and the heat ignites this mixture. Small amounts of sodium atoms are carried up into the flame, where the heat ionizes them. As these excited ions relax back to their ground state they emit yellow/golden color photons, giving the flame its hue.
Why can you only get certain amounts of isotopes such as hydrogen having none or 1 or 2 neutrons and not 3 or above?
heavier isotopes can be produces but their halflives are in the microsecond or shorter range.
What is the major source of energy the sun produces?
The major source of energy the sun produces is through nuclear fusion reactions in its core. Hydrogen atoms are fused together to form helium, releasing vast amounts of energy in the process.
Does water react with sodium?
Yes, water reacts with sodium vigorously, producing hydrogen gas and sodium hydroxide. The reaction is highly exothermic and can lead to a release of large amounts of heat and potentially cause the hydrogen gas to ignite.
What metallic elements are found in malachite?
Malachite is a copper carbonate hydroxide mineral, with the formula Cu2 CO3 (OH)2, so your answer would be 'copper'
