What else can I help you with?
What safety hazard might occur if a partially filled aerosol can is exposed to excessive heat?
The pressure inside the aerosol can can increase, leading to the risk of explosion if the can is exposed to excessive heat. This can result in injuries to individuals nearby and also create a fire hazard. It is important to store aerosol cans away from heat sources to prevent this.
What happen when urine is exposed to air?
When urine is exposed to air, it can undergo a process called oxidation which can cause it to develop a stronger odor and potentially change color. Bacteria in the air can also start to break down the urea in urine, resulting in ammonia being released, further contributing to the smell.
Which gas is released when caOCl2 is left exposed to air?
When Ca(OCl)2 is left exposed to air, it may release chlorine gas (Cl2). This can occur through a decomposition reaction, where the compound breaks down to release oxygen and chlorine gases. Chlorine gas is harmful if inhaled and can be toxic in high concentrations.
How does paramagnetic color change occur in materials?
Paramagnetic color change in materials occurs when the material is exposed to a magnetic field. This causes the alignment of the material's magnetic moments, resulting in a change in its optical properties and color.
How does chemical reaction occur in a coal?
Coal is primarily composed of carbon, which can undergo chemical reactions such as combustion when exposed to heat and oxygen. When coal is heated, the carbon in it reacts with oxygen in the air to produce carbon dioxide and heat energy. This is the basis of how chemical reactions occur in coal.
What does iron have to be exposed to for oxidation to occur?
Iron has to be exposed to oxygen for oxidation to occur.
How do radiation burns occur?
If you are exposed to it too long.
What must a chloroplast be exposed to for photosynthesis to occur?
the sun.
How long would it take for oxidation to occur on exposed car body metal?
If exposed to the elements, minutes.
What chemical reactions occur in rust?
rust oxidizes when exposed to water
if rotation did not occur, one side of the earth would be continutally exposed to the?
Sun
Is a sliver crystal a mineral?
Yes. Silver crystals occur in nature (known as 'native silver') and can be gown in the laboratory. All pure metals can be regarded as minerals.
All but which condition must be present for light-independent reactions to occur?
the plant is exposed to light
Physical or chemical changes that occur in exposed crustal material through the activity of the forces of nature is?
erosion
What chemical change takes place when steel is exposed to water?
Corrosion occur if oxygen exist also.
When materials contain iron are exposed to water and oxygen?
The iron will become oxidized and we will say that it has become rusty.
Do duststorms occur only in the desert?
No, dust storms can occur anywhere there is dry, exposed soil when the wind is strong such as an open, ploughed field, playground, construction site, etc.
