Why white phosphorus does not react with water?
These two most common forms of the element Phosphorus react differently because they are bonded differently. White phosphorus is structured as individual molecules of 4 atoms bonded together to form a tetrahedron. The P4 rings are held to each other by physical bonding (like other molecular substances) but no chemical bonding. These P4 rings are an unstable arrangement which makes the white phosphorus extremely reactive. Red phosphorus also has groups of 4 atoms, but they are not rings. One side is open, which allows each P4 group to chemically bond to a neighboring group, so that a huge amorphous network is formed instead of individual molecules. This is a relatively stable arrangement which makes the red phosphorus less reactive.
When a substance doesnt dissolve in water what is it said to be?
This substance is insoluble in water.
In which liquid does sulfur dissolve?
Sulphur dissolves in a liquid called carbon disulphide.
Is dissolution of sulfur in carbon disulphide is chemical or physical change?
The dissolution of sulfur in carbon disulfide is a physical change because no new substances are formed. The sulfur particles are still sulfur particles, they are just dispersed within the carbon disulfide, similar to dissolving sugar in water.
What is the only biogeochemical cycle which does not pass through the atmosphere?
The phosphorus cycle is the only biogeochemical cycle that does not pass through the atmosphere. Phosphorus remains mainly in rock and sediment deposits, where it can be released through weathering processes and taken up by plants. It is then transferred through the food chain and eventually returns to the soil and water bodies.
Is phosphoric acid soluble in ethers?
Sulphur is insoluble in water but soluble in carbon disulphide.
Is water lighter than carbon disulphide?
no,it is heavier than water and so it'll sink
Is carbon disulphide an electrolyte?
it is a covalent compound so it is a non-electrolyte.
How do you separate iron filings salt sugar and carbon disulphide?
1. Salt will dissolve in carbon disulphide 2. Now we have a mixture of iron filings sugar and carbon disulphide(salt dissolved in it) 3. Separate iron filings by magnet. 4. Remove the sugar by Decantation process. 5. Separate carbon disulphide and salt by distilation.
Why sulfur is soluble in carbon disulphide but not in water?
SOLUBILITY OF SULPHUR IN CARBON DISULPHIDE:Because carbon disulphide and sulphur both are non polar molecules therefore, sulphur is soluble in carbon disulphide while water is a polar molecule and not allow sulphur to dissolve
Which element occur in compounds that are insoluble in water?
Many organic compounds are insoluble in water. They have carbon and hydrogen as elements.
Is carbon disulphide denser than water?
Density carbon disulphide (as liquid) varies from 1.2927 g/cm3 (0 °C) to 1.266 g/cm3 (25 °C) so it is more than 25% denser than water. Remember it is very volatile.
Sulfur is soluble in which solvent?
Sulfur has low solubility in water, but it is soluble in organic solvents such as carbon disulfide, benzene, and toluene.
What is iodine soluble in?
Iodine is highly soluble in water. It is also soluble in iodine solutions, chloroform, carbon tetrachloride and carbon disulphide among others.
Why is pencil insoluble?
Pencils are insoluble in water because the main components of a pencil, graphite and clay, do not dissolve in water. Graphite is a form of carbon that is extremely stable and does not react with water, while clay is also insoluble in water. This is why pencils can be used to write on paper without smudging when they come into contact with water.
Is water a solution then what is its characteristics?
Water isn't a solution it's a liquid, a soltion refers to soulte dissolved in a solvent E.G. NaCl(aq) this is a soltion of sodium chloride in water, water is the solvent NaCl is the solute. This is an ionic example. E.G. 2 Phosphorus in carbon disulphide - P4 is the solute, CS2 is the solvent - this is a covalent example
What is different about the phosphorus cycle as compared to the water-carbon nitrogen cycle?
The atmosphere is not involved in the phosphorus cycle.
