How do you know if a chemical will float in water?
A chemical will float in water if its density is less than the density of water (approximately 1 g/cm3). This can be determined by comparing the densities of the chemical and water. If the chemical's density is less than water, it will float; if it is greater, it will sink.
What type of chemical reaction when sodium thiosulphate is dissolving in water?
When sodium thiosulfate dissolves in water, it undergoes a physical change rather than a chemical reaction. The sodium thiosulfate molecules are surrounded by water molecules, causing them to separate and disperse throughout the solution. This process is known as dissolution, where the ionic compound breaks apart into its constituent ions without any chemical bonds being broken or formed.
What environment has the greater concentration of dissolved oxygen warm water or cool water?
Cool water typically has a greater concentration of dissolved oxygen than warm water. This is because oxygen dissolves better in colder water than in warmer water. Oxygen levels in water are important for supporting aquatic life and ecosystems.
Is the equilibrium constant greater than 1 in the given chemical reaction?
To determine if the equilibrium constant is greater than 1 in a chemical reaction, compare the concentrations of products to reactants at equilibrium. If the concentration of products is greater than reactants, the equilibrium constant is greater than 1.
Can Antimony float in water?
No, the density of antimony is more than six times greater than the density of water so it will sink in water.
Why is the density of ocean water greater than tap water?
because salt is higher density than water and dissolves in the water, increasing density
How do you know if a chemical will float in water?
A chemical will float in water if its density is less than the density of water (approximately 1 g/cm3). This can be determined by comparing the densities of the chemical and water. If the chemical's density is less than water, it will float; if it is greater, it will sink.
What will happen if an object has a density greater than water?
If inserted into the water as a solid "blob" then it will sink - unless it dissolves first. But, if because of the shape, the mass of water displaced by whole object is greater than the mass of the object, it will float - just as ships made of metal do.
Why can carbon dioxide diffuse in the body 20 times faster than 0xygen?
This is because Carbon dioxide is about 25 times more soluble in water than oxygen at body temperature. Carbon dioxide is more soluble because a chemical reaction takes place with water when it dissolves forming Carbonic acid when combined with water. There is no chemical reaction taking place when oxygen dissolves in water.
Is adding silver nitrate to water a physical or chemical change?
When silver nitrate is added to water, it undergoes a physical change as it dissolves in the water. No new substances are formed during this process, so it is considered a physical change rather than a chemical change.
What type of chemical reaction when sodium thiosulphate is dissolving in water?
When sodium thiosulfate dissolves in water, it undergoes a physical change rather than a chemical reaction. The sodium thiosulfate molecules are surrounded by water molecules, causing them to separate and disperse throughout the solution. This process is known as dissolution, where the ionic compound breaks apart into its constituent ions without any chemical bonds being broken or formed.
Is iron carbonate a soluble salt?
Its Lattice energy is greater than the solvation energy of water.
How do you get dried model glue out?
The only chemical that dissolves it does more damage than the glue.
Why does sugar dissolves faster in hot water than in cold water?
yes
Why doesn't a sugar cube float in water?
A sugar cube sinks in water because it is denser than water. The density of an object determines whether it sinks or floats in a fluid. Since the sugar cube is denser than water, it displaces less water than its own weight, causing it to sink.
Is mixing salt and water a chemical property?
It is neither chemical not is it a property. It is a physical change.
Which dissolves fastest in water do sugar or salt?
Sugar dissolves faster than salt. When a substance dissolves into another substance, it turns into a solution. The substance that is dissolved is the solute.
