5.FAQ

1, how about your packing?

My main packing is 25kg or 1000kg PP PE or kraft bag , with or withour pallets,with or without anticaking. We also can make packing and shipping mark are your ask, such as 50kg/50bl bag.

2, ‍how long time you can make the shipping?

We can make the shipping within 5-10day after confirm the order.

‍3, why you buy from me?

We have stable quolity and price, not best quolity and price. It is not true for best quolity and best price. Our factory is manufacture according the BP USP and FCCIV terms. We have in this line for more than 8 years. We are one of the biggest exporter from Qingdao port.

Q:and what are the kinds of organic compounds?..pls. help me abt. this..thanks!..(^_^): I think organic compunds are anything with Carbon(C), although I really don't know.

Q:Chemical formula The longest inorganic salt: The primary stage on the salt, acid salt and so on

Q:Why can quaternary ammonium salts catalyze the heterogeneous reaction between water-soluble inorganic salts and organic compounds: Quaternary ammonium salts have the characteristics of surfactants, with the water phase of the nucleophile in the composition of the ion pair, into the organic phase, thereby promoting the heterogeneous reaction faster 6224

Q:Several inorganic salts are lacking in symptoms and food sources: Ingredients of iodine-containing inorganic salts (trace): seaweed, jellyfish, corn, mussels, etc.

Q:What are organic and inorganic salts?: Salt is a mineral from the Earth. Salts similar to iodized are extra munufactured and aren't fully typical. However salts like sea salt have the leat amount of processing. Some say that sea salt is healthier since it's he most traditional state of salt that you could get in mass production. I wolud must agree with them.

Q:An inorganic salt is dissolved in water and yields a solution that has a color. Make a statement about the type of element the substance contains that casuses the color.Thanks!: Many inorganic salts form colored solutions . pper ( II) sulfate ( Blue ) nickel (II) acetate = green, mangaanse ( II) chloride = pink, iron(III) chloride = yellow, potassium dichromate, orange and so many more Can you be more specific ?

Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?: The main physiological functions of minerals: 1. constitute the body of the material. (Such as calcium, phosphorus, magnesium is a bone, an important component of the teeth.) 2. Regulate the physiological function. (Minerals are often enzymes activators.) 3. Participate in the regulation of body fluid balance and maintain the body's acid-base balance.

Q:Are there any differences between minerals and inorganic salts?: There are differences, some minerals exist in organic matter, and some minerals are inorganic salts. Inorganic salts are inorganic.

Q:My body fat rate 14.6 normal body fat percentage 31.2 is more than the normal value I do not know the difference between the two please God answer ah Thank you very grateful and then those elements of my lack of God is the situation ah I love meat is not a vegetarian! And I super love to eat eggs! And my super love to drink water!: The gym can also be measured

Q:A. oxygen demanding wastesB. organic plant nutrientsC. inorganic plant nutrientsD. water soluble inorganic chemicalsE. sediment: Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment
