What is the reaction between aluminium sulphate and sodium bicarbonate?
aluminium sulphate solution rects with sodium bicarbonate to give aluminium hydroxide, sodium sulphate and carbon dioxide. Al2(SO4)3 +6 NaHCO3 = 3 Na2SO4 + 2Al(OH)3 + 6 CO2 This reaction can be seen in a foam based fire extinguisher
Why does an aluminium vessel loose its shine soon after use?
Oxidation of aluminum, formation of a thin layer of aluminum oxide.
You can see your reflection in a miror because metals tend to be what?
When a photon of light hits a mirror it cause the electrons in the mirror's atoms to vibrate and give off identical photons of light. Metals work better as mirrors because they have a large number of
What has the most common element used in wires?
Copper is used in electric wires because it is the best conductor of electricity that is known, apart from silver which is slightly better. For overhead wires a common material to use is aluminum because it is much lighter, although not such a good conductor. Overhead high-voltage wires usually use aluminium stranded wire with one or more steel strands in the centre to give strength.
What chemicals give glue its smell?
Glue typically contains chemicals such as formaldehyde, acetone, and toluene which can give it its strong and distinct smell. These chemicals can evaporate into the air and create the odor that is often associated with glue.
What are mirrors that give blurry image?
Mirrors that give a blurry image may have imperfections in the glass such as scratches, warping, or a deteriorating reflective coating. These imperfections can distort the reflection and cause the image to appear blurry.
Define reflection and give an example?
Reflection is the ability to think deeply or carefully about something. For example, after completing a project, you could reflect on what went well, what could have been done better, and what you learned from the experience.
What happens when aluminium reacts with nitric acid?
Aluminium reacts with dilute nitric acid to give aluminium nitrate and hydrogen gas. aluminium + nitric acid -> aluminium nitrate + hydrogen 2Al(s) + 6HNO3 (aq) -> 2Al(NO3)3 (aq) + 3H2(g)
What is the balanced equation for aluminium reacting with iodine to give solid aluminium iodine?
2Al + 3I2 -> 2AlI3
Can you give a project on color reflection?
yes
Can you give a sentence with the word reflection?
The reflection of the sunset in the pond was really quite stunning.
How do you get steelix Pokemon LeafGreen?
give it metal coating and trade it.
What are the necessary conditions for a surface to give an accurate reflection in the experiment of the laws of reflection?
The surface should be smooth and flat to give an accurate reflection in the laws of reflection experiment. A rough or curved surface may distort the reflection, making it difficult to observe and verify the angle of incidence equals the angle of reflection. Additionally, the surface should be clean and free from any dirt or smudges that could interfere with the reflection.
How much aluminium would be required to make 34.5g of aluminium oxide by reacting it with oxygen?
9.13g Al will give 34.5g Al2O3 when fully oxidized
What type of reflection does a mirror give?
A mirror gives specular reflection, which is the reflection of light in such a way that an incident ray of light is reflected at an equal angle to the normal. This type of reflection creates a clear and sharp image.
Does aluminium give off toxic fumes?
Aluminium itself does not give off toxic fumes at room temperature. However, when heated to high temperatures above 660 degrees Celsius, it can produce fumes that may be harmful to inhale. It is important to take proper precautions when working with heated aluminium to avoid exposure to these fumes.
Give example of mirror?
You look in it and hay presto, you have a reflection.
