cold flame forms
If you are worried about the fact that this is a [2+2] cycloaddition, which you would expect to be forbidden, I would suggest (though this is out of my area) that the re-hybridisation of the phosphorus atom may be relevant, since the use of a d-orbital introduces an additional nodal plane.
hello, here is some information regarding phosphorus trioxide It is obtained by the combustion of phosphorus in a limited supply of air at low temperature. P4(s) + 3 O2(g) → P4O6(s) Phosphorus trioxide reacts with cold water to form phosphorous acid. P4O6(s) + 6 H2O(l) → 4 H3PO3(aq) It reacts vigorously with hot water, via a complex set of reactions, to form red phosphorus, phosphines, H3PO3 and H3PO4. dr.virag
The hypothesis for a dew point experiment could be that as air temperature decreases, the dew point temperature will be reached, causing water vapor in the air to condense into liquid water droplets, forming dew.
By seedPieris....can be grown from seed in a cold frame in spring or autumn, greenwood cuttings in early summer or semi ripe cuttings in mid to late summer with bottom heatIt is possible to root cuttings but it is usually done by grafting.
The temperature in a swamp can vary depending on location, time of year, and time of day. On average, swamp temperatures can range from 10°C to 30°C (50°F to 86°F) but can fluctuate based on environmental factors.
The safety flame, the cold one, is wavy.
A flame cannot be any cold but always hot even at the first instant it is lit.
Cold flame sparklers have a unique feature where they produce a cold flame that is safe to touch. This is different from traditional sparklers, which produce a hot flame that can cause burns if touched. Additionally, cold flame sparklers do not emit smoke or ash, making them a cleaner option for indoor use.
No, the experiment does not show that cold water boils faster than hot water.
maybe its the cold?
A blue flame is neither too hot or too cold as somebody else has said. But the gentle blue flame is good for heating something up with a temperature that is between the yellow safety flame and the roaring blue flame.
The hot can in cold water experiment results in the can collapsing due to the rapid cooling of the air inside, creating a vacuum that crushes the can.
Flames cannot appear on Mars, because there isn't any oxygen on Mars. Fire, or flames, are fueled by oxygen, and since there isn't any oxygen on Mars, it is impossible to perform flame tests on Mars.
The steel having this defect cracks when being worked in cold state. This defect is due to presence of excess of phosphorus
A Bunsen burner flame can reach temperatures up to around 1,500 degrees Celsius (2,732 degrees Fahrenheit).
The flame that you use the most is the safety flame. The safety flame is the yellow one it is not too hot and not too cold. The air hole should be half open for the safety flame and it makes a hissing sound. Your Welcome xx :D
If a beaker with cold water is held in a yellow burner flame, the water will begin to heat up as it absorbs the thermal energy from the flame. Eventually, the water will reach its boiling point and start to evaporate. It's important to note that the yellow flame indicates incomplete combustion, which can produce soot and carbon monoxide.
