What else can I help you with?
Which element reacts more rapidly in water lithium or potassium?
Potassium (K) reacts most rapidly with water.
Which metals act violentely with water?
The Alkali metals (group 1) and the Alkali Earth metals (group 2) react violently with water. Lithium and magnesium show slow reactions in boiling water. Sodium and potassium reacts violently with flames with cool water. The elements in higher periods (strontium, barium etc.) react explosively.Elements in the 1st group react rapidly with cold water. The rate of reaction increases down the period. The elements in the 2nd group also reacts with hot water or steam.
What chemical reaction where a substance reacts rapidly with oxygen?
One example of a chemical reaction where a substance reacts rapidly with oxygen is combustion. In combustion, a substance, such as a fuel like gasoline or wood, reacts with oxygen in the air to produce heat, light, and various combustion products like carbon dioxide and water vapor.
What is given out when sodium reacts with water?
Sodium melts to form a silvery ball which moves about quickly on the water surface, producing hydrogen gas rapidly
What group on the periodic table reacts violenty with water?
Group one elements react vigorously with water.They even react when exposed to air.For example lithium reacts violently with water.
How can a chemical reaction be used to separate important elements?
For example, water reacts with zinc, releasing hydrogen, an element.
A piece of sodium that's dropped into a beaker of water?
When a piece of sodium is dropped into water, it reacts violently, producing hydrogen gas and heat. The reaction may lead to flames or an explosion due to the rapid release of hydrogen gas. This is because sodium is highly reactive with water, forming sodium hydroxide and releasing energy in the process.
What happens when a dilute acid is dropped onto carbonates?
When a dilute acid is dropped onto carbonates, a chemical reaction occurs where the acid reacts with the carbonate to produce carbon dioxide gas, water, and a salt. For example, when hydrochloric acid is dropped onto calcium carbonate, the reaction produces carbon dioxide gas, water, and calcium chloride.
What are the observations when potassium reacts with water?
Potassium reacts vigorously with water, as it is one of the most reactive alkali metals. When it does, it floats on top of the water, and burns a lilac flame. It also may explode. Fizzing and bubbling will also be seen as hydrogen gas is produced. The potassium reacts with the water to become a hydroxide (potassium hydroxide)
What metal elements will form an alkali when dropped into cold water?
After this reaction alkaline hydroxides are formed and hydrogen is also released.
What happens when water reacts with krypton?
Water does not react with krypton, as krypton is a noble gas that is inert and does not readily form chemical compounds with other elements.
How do you determine if a salt is basic?
Salts can create acidic or basic solutions by containing a conjugate base and a weak acid, which when dropped in a solution of water reacts with the water to form a solution with a pH greater than seven.
