What is the chemical equation for aluminum being dissolved in water?
Aluminum does not dissolve in water.
Why does electrolysis turn water murky?
The question needs to be more specific. What method of electrolysis are you performing. Are you using aluminum foil and salty water? If you are, the NaCL (salt) will be electrolysed to form NaOH (lye) and also giving off chlorine gas. (which can be dangerous in sufficient quantity) The sodium hydroxide (lye) will in turn attack your aluminum foil creating aluminum oxide. This aluminum oxide it what is causing your water to be murky. Carbon electrodes are a better option.
What is the specific gravity of aluminium in kg?
the atomic mass is 26.981539 if that's what you're looking for. NO. Not at all. The question wasn't atomic weight, but SPECIFIC WEIGHT. SPECIFIC WEIGHT is the ratio of DENSITY of the material to the Density of Water at an established set of conditions. Thus, the Specific weight of Aluminum is approximately 2.7 times the weight of water. So that if you have a cubic foot of aluminum, it will weight more or less two point seven times the weight of a cubic foot of water, that is around 168.5 pounds, but bear in mind that different commercial aluminum alloys can vary from 2.5 to 2.9 in their specific weight, but 2.7 is a good value for practical purposes.
What materials you need to find the density of aluminum?
You need some aluminum, a scale to determine the mass, and a measuring cup halfway filled with water to determine the volume of the piece of aluminum by substracting the volume after and before you drop the piece of aluminum in the water. Then you can calculate the density of the aluminum = mass / volume.
Can aluminium float in water?
A solid bar of aluminum would not float, since its density (almost 3 grams per cc) is greater than that of water (1 gram per cubic centimeter). For an object to float in water, its density would have to be less than 1.0.
Which of the following statements about water is false. Liquid water has a low specific heat which makes it a poor coolant 2 Solid water ice is less dense than liquid water or what?
Your first statement is false, water actually has a high specific heat and therefore is a good coolant.
If the specific heat of aluminum is 0.902 and the specific heat of copper is 0.268 what makes copper a better choice to use for hot water lines in your house?
This means that copper will not absorb the heat from the water as much as the aluminum. Aluminum will "steal" more heat from the water- which you do not want. You need the heat to stay with the water until it serves its purpose.
Which of the following statements about fluid pressure is correct SEE Discuss for choices?
"If you are 15 ft. under water, the pressure will be the same no matter how large the body of water is" is a true statements about fluid pressure.
Which of these substances has the highest specific heat A aluminum B glass C sand D water?
B Glass
What properties does aluminum cookie sheet have?
An aluminum cookie sheet would not be a great idea. Aluminum has a specific heat of .900 J/g° Celsius. Specific heat is the heat an object has to get to before it starts actually heating up, so the higher the specific heat the harder it is to heat up. To have a comparison Gold, the best conducter metal, has a specific heat of .129 J/g° Celsius, and Water has a specific heat of 1.000 J/g° Celsius. Aluminum's specific heat is so high you might as well be baking cookies in water... if that were possible. Aside from that, if aluminum had a lower specific heat it would be great for a cookie sheet. It doesn't rust, its cheap (.05$ per oz), it doesn't explode while in contact with air or water (like potassium), and it generally lasts over a lifetime. But because the specific heat is so high, there's really no point in using it as a cookie sheet. I suggest copper.
Which of the following are good conductors under normal conditions water plastic a penny copper wire a dime or aluminum foil?
aluminum foil, dime, coper wire, penny, water
Is aluminum sulfide soluble in water?
Aluminum sulfide decomposes in water.
What is the SPECIFIC name given to the following reaction glucose galactose lactose water?
Condensation
Does aluminum dissolve in water?
Under normal circumstances, aluminum does not react with water.
What is the chemical equation for aluminum being dissolved in water?
Aluminum does not dissolve in water.
Is water or aluminum a better conductor?
Aluminum is a much better conductor than pure water. Salty water conducts as well as aluminum, however.
What is the mass of a piece of aluminum with a volume of 12.2 cm cubed?
Aluminum has a specific gravity of 2.7, therefore its mass is 2.7 times the mass of an identical volume of water. 12.2 cm3 of water has a mass of 12.2 grams, so 12.2 cm3 of aluminum has a mass of 32.94 grams (2.7 x 12.2 grams).
