SULPHONATED NAPHTHALENE FORMALDEHYDE

1.Product General

FDN-A ,FDN-B,AND FDN-C Superplasticizer is a dry powdered admixture. It is produced through such a process: 1) sulphonating refined naphthalene with sulfuric acid, 2) condensing with formaldehyde, 3) neutralization, and 4) filtering. It conforms to GB8076-1997 and is mainly used for various high-strength concrete, steel concrete, prestressed concrete, large formwork concrete, slipforming concrete etc.

Q: Apart from flavor enhancers, what other food additives are addictive?: sugar, salt, caramel coloring

Q: What are the disadvantages of food additives?: Autism, cancer, obesity......

Q: so i guess we learned this when i was sick at schoolits due tomorrow and if i dont finish this ill drop from a b to a D. so i reallly need help.so it says; Find the additive inverse of each polynomial.and the examples are: Sample 1: 6y-3z Solution: -6y+3zSample 2: -a?-2ab+3b?Solution: a?-2ab+3b?i DONT UNDERSTAND THIShow do they get the answer?could you do this problem for me and explain how you did it? : 2a+9b 4xy?+6x?y-y?PLEASEthis depends on my grade for this semester.: The first example makes sense. You add the two and you get 0. Do you have the signs right in the second solution? 2a+9b -2a-9b Add them and you get 0 4xy^2+6x^2y-y^3 -4xy^2-6x^2y+y^3 It's a matter of changing the signs and adding. The additive inverse is what's added that will give 0, the identity for addition.

Q: I need to find the inverse of -2x + 3y – 4z and put it in simplified possible form?: additive inverse is that number with which you add the original number and get zero so the additive inverse of this number is -(-2x+3y-4z) 2x-3y+4z when you add this additive inverse with the original number provided in the question you get zero

Q: 7 what is the additive inverse and what is the absolute value?: I forget the name of the motorcycle, but it is made with a left handed operations. If you are buying a new motorcycle, the manufacturer or dealer can make the adjustments and they should be little or no cost to you.

Q: Whether the margarine is a food additive: Is a product, not an additive.

Q: Hi I wonder if anybody knows or had great experience with this brand CHAMPION for car additive?: They are all pretty much the same. Doesn't matter what brand you get. Just like gas, 15 different brands, but they all pretty much sell the same thing. If you want to save money, I buy my additive by the gallon, at truck stops. It is a fuel system cleaner that treats diesel and gas engines. It cost about $28. Cleans injector, carbureators, fuel induction, pistons, valves, etc. 1 gallon treats something like 400 gallons. It is kind of thick. So I just give it a quick sploosh into the gas filler neck each time I change the oil. The only exception to this, is I have had good luck with chevron/techron fuel system cleaner. Kind of pricy $8 only treats 10 gallons. But has worked wonders on both of my Cadillacs. I was reluctant, but word of mouth was the deciding factor.

Q: why are food additives found in processed foods?: The additives are much cheaper than the food so companies put in as many chemicals as they can get by with.

Q: Is it illegal to add hydrogen peroxide to food?: As China's current health food management and norms there are loopholes, the scope of food additives to supplement is not timely, which led to the introduction of 1996, "food additives use health standards" (GB2760-1996) added content has not been the content , Of course, including the use of hydrogen peroxide and so on. Due to the specific use of hydrogen peroxide range, many people even the relevant departments that hydrogen peroxide can not be used in health food varieties, but can not remain in the product; for the product of hydrogen peroxide residues did not define a Standards and safety.

Q: Find the additive and multiplication inverse of -2/3?: Inverses together make the identity for that operation. The identity for add is 0 so -2/3 and 2/3 are additive inverses because they add to be 0. The identity for multiply is 1 so -2/3 and -3/2 are multiplicative inverses because they multiply to be 1.
