Q:With aluminum foil wrapped 0.1mol metal sodium in water by needle konza a plurality of small holes, after complete reaction, the volume of gas released (standard) (for)A. cannot determine that B.1.12L C. is greater than 1.12L and D. is less than 1.12L

0.1molNa fully reacts to generate V (H 2), =2n (Na),.V, m, =2 * 0.1mol * 22.4L/mol=4.48L > 1.12L,So choose C.

Q:Aluminum foil waterproof material, how much does it cost for a square?

It depends on whether you are using SBS waterproof membrane or self-adhesive waterproof coiled material

Q:Considerations for hand held aluminium foil sealing machine?

3, the machine is equipped with automatic overheat protection function, when the internal temperature of overheating, green "overheating" bright lights, you should immediately can continue to work out in the standby light or cooling.4, white glue boards often view the inductive head in front of the color, if there are serious undo charred discoloration, inductive head rib cover to check, whether the induction coil insulation paint carbonization or fall off, if this phenomenon should replace the coil head or the induction time, continue to use so as not to damage the host.5, when the induction foil area is too large, press the induction switch, time display immediately to zero without induction or red "overcurrent indicator" flashing with "drop" sound the alarm when the time should be increased by letter and the distance between the sensor head of the post, can work normally. Can use rubber boards and other things to do the stalls, do not use metal materials instead.

Q:What is aluminum foil, please?

With metal foil Mylar foil backing, and adhesive polyester tape (PET PP) attached to the thin, 7 m and 9 m aluminum foil, in recent years with the change trend of electronic industry products small thin, the thickness of 4UM foil has gradually increased, due to the application of industry and different end use.

Q:Can I use the foil instead of the baking paper?

If you bake cookies and the like, you can replace it, but consider the cost. Oh, the foil is a lot more expensive.

Q:For the first time, the microwave oven roast chicken wings, no use of aluminum foil, baked chicken wings can also get in, but the microwave oven is oil, the roast, bought a foil, but do not know how to use, is wrapped in chicken wings or on the grill, how much time temperature? Does the foil burn when the temperature is high? The first 4 minutes with no bake aluminum foil side, a total of 8 minutes OK!! I don't know how to use aluminum foil this time Headache...

Hold it evenly and refrigerate for two hours.After the removal of each wing is uniform with cornstarch.Put the microwave oven on the grill for twelve minutes and turn over halfway.

Q:Which packing material is better, such as shielding bags, aluminum bags and aluminum foil bags?

Q:The foil can be used in the microwave heating?

Microwave produced by microwave oven belongs to radio frequency band, usually around 2500MHz. This band of microwaves has the following features: 1) it can be absorbed by food and water, causing molecules to move violently and produce heat. 2) not absorbed by plastics, ceramics, or glass. 3) the metal conducts electricity under the influence of the electric field of the microwave

Q:How to calculate the aluminum foil material?How can we calculate the number of meters with weight, length and thickness?

Method two, the known aluminum foil density is 2.71 (with 1mm thick aluminum foil as standard), thickness 0.1mm, aluminum foil net weight 3KG, width 1000mm, calculation method:0.1mm aluminum foil base weight: 0.00271*100=0.271Converted to square meters per kilogram: 1 (1 kg) /0.271=3.69003690036 m2 / kg3 kilograms: 3*3.69003690036=11.070110701 square meters, that is, 3 kilograms =11.070110101 meters

Q:With a small crucible clamping of aluminum foil, heating to melt, the alcohol lamp gently shaking, observed foil melting, lose luster, but the molten aluminum does not fall, like a layer of film bag, please answer the reasons for this phenomenon ______.

Lost luster; because of the high melting point of alumina, the inner layer of molten aluminum wrapped up by the oxide film does not drip when heated,
