Why carbonate of lithium is not stable?
Lithium carbonate is generally stable, but it can react with acidic solutions to form lithium ions, which are water-soluble. This can lead to the gradual decomposition of lithium carbonate over time in the presence of moisture or acids. Additionally, lithium carbonate can absorb carbon dioxide from the air, forming lithium bicarbonate, which can further contribute to its instability.
What happens to a fresh cut piece of lithium after few minutes?
Pure lithium, (as exposed by a freshly cut surface), oxidizes rapidly in air to form a thin oxide coating, dull silvery-gray in appearance, that thickens over time to a black lithium oxide tarnish. Conditions of high ambient air temperature and humidity hasten this process.
What kind of chemical reaction is waterfall?
A waterfall is a physical process, not a chemical reaction. It involves the flow of water over terrain due to gravity, and does not involve a chemical change in the water molecules themselves.
Why does the reaction decrease as the reaction progresses?
There are fewer reactants left to collide.
What is the difference between reagent and catalyst?
A reagent is a substance consumed during a chemical reaction to produce a specific product, while a catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. In other words, reagents participate in the reaction, while catalysts facilitate the reaction without being altered themselves.

What are 3 compounds made by lithium?
Lithium not occur free in nature, combined is is found in small amouts in nearly all igneous rocks and in the waters of many mineral springs. Lepidolite, spodumeme, petalite, and amblygonite are minerals that contain it. Lithium also being recovered from brines of Searles Lake, in California, and in Nevada.Deposits of quadramene are also found in North Carolina. Lithium is produced electrolytically from the fused chloride. a common compounds of lithium is Li2CO3. lithium carbonate, it is used in glass or ceramics to make it stronger. Lithium carbonate is used in products such as glass cookware and black and white television tubes. As on 1996, 40% of lithium used in the United States was used as part of lithium carbonate. Lithium carbonate can also be used in pill form to treat bipolar disorder. Its origins for use for mental health are rooted in 1949, when John Cade (1912-80) discovered that lithium carbonate benefits patients with bipolar disorder. Although lithium compounds can be good for your health, they are known to cause kidney damage. Lithium deuteride is a constituent of some - perhaps nearly all - thermonuclear weapons.
When does a hurricane increase its speed?
A hurricane increases its speed when it is over warm water.
Why did ian thorp start swimming?
to get over his alergic reaction to the water
The reason for using powered calcium carbonate CaCO3 and heating the reaction mixtures up are?
Powdered: increases surface area the reaction happens over, thereby increasing the rate of reaction Heat: Provides energy for the reaction. Particles move faster, therefore collide more frequently. also, more particles have sufficient energy to react when they collide. This also increases rate.

What effect does a catalyst have?
A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does so by providing an alternative reaction pathway that requires less energy to initiate the reaction. The catalyst itself remains unchanged at the end of the reaction and can be used over and over again.

Do water in the hydrosphere increases or decreases over time?
The amount of water in the hydrosphere remains relatively constant over time due to the water cycle, which involves processes like evaporation, condensation, precipitation, and runoff. However, the distribution of water can change regionally due to factors like climate change or human activities.
What happens to water in light dependent reaction?
the water dries up and emoes all over the world sit and cry
What process in the water cycle increases the salinity of ocean water?
The process in the water cycle that increases the salinity of ocean water is evaporation. As water evaporates from the oceans, it leaves behind its salt content, causing the remaining water to become more saline. When this water vapor condenses and falls back into the ocean as precipitation, it is essentially fresh water, so this cycle of evaporation and precipitation increases the overall salinity of the oceans over time.
What causes an alkali metal to move over the surface of water while reacting with it?
The densities of lithium, sodium and potassium are less than that of water and so they float on water. They react with water to produce hydrogen gas and this propels the metal across the surface of the water.
