11. Packing
50kg or 100kg iron drum
Cautions during transportion:
The packing must be kept in good condition and the goods should be stored in a dry,cool and ventilated place.It should be separate from the cargo can burn and acid.It should avoid meeting water and moisture.It should give off the acetylene in iron drum before storing in warehouse. Rolling drums,heavy putting down and colliding are not allowed to avoid the spark leads to explosion.
- Q: What is the time when the maximum number of inorganic salts is needed
- Nitrogen is the basis of many important organic compounds in the body, such as protein, nucleic acid, chlorophyll, enzymes, vitamins, alkaloids and some hormones, etc. Nitrogen is also the basis of genetic material. In all organisms, the protein is most important, it is Often at the center of metabolic activity, which is the primary factor limiting plant growth and yield, and has a significant effect on improving product quality.
- Q: What inorganic salts and trace elements are there in rice?
- Pantothenic acid (0.60 mg) Carbohydrate (76.80 grams) Folic acid (3.80 micrograms) Dietary fiber (0.60 grams) Biotin (220.00 micrograms) Thiamine (0.33 mg)
- Q: Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit
- Boron has a great influence on the reproductive process of plants, which can accelerate pollen differentiation and pollen tube elongation. In the absence of boron, pollen tube germination is affected, poor fertilization, which leads to the formation of seeds affected, the reduction of growth hormone produced by the reduction of growth hormone will affect the formation of fruit.
- Q: I am an AP biology student testing how magnesium effects the rate of photosynthesis in a plant. However since my class period is only one hour long I highly doubt if i add epsom salt to the soil ( after mixing it with water) i will see an immediate increase in the rate of photosynthesis. So i need to know how long should i wait to test photosynthesis rates after adding an epsom salt solution to the soil of a plant. Or how long does it take for magnesium to be incorporated into a plants rate of photosynthesis. Thanks in Advance!
- Magnesium sulfate (or magnesium sulphate) is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4·7H2O), commonly called Epsom salt, Magnesium is part of the chlorophyll in all green plants and essential for photosynthesis. It also helps activate many plant enzymes needed for growth. Rate of photosynthesis does not depend upon any single factor . so it is futile to expect it should increase after addition of epsom salt to soil in solution form . Because first it should be incorporated in chlorophyll molecule . That depends upon formation of new leaves . Old leaves already have it ( formula of chlrophyll a = C55 H72 O5 N4 mg ) That is the requirement is just one atom per molecule . what to do with excess ? Unless the soil is deficient in Mg . It it useless to add it . soil pH is another factor to be considered = Soil pH (a measure of the acidity or alkalinity of the soil) Soil pH is one of the most important soil properties that affects the availability of nutrients. Macronutrients tend to be less available in soils with low pH. Micronutrients tend to be less available in soils with high pH. www.ncagr /cyber/kidswrld/plan...
- 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: In order to prove that magnesium is an essential salt for soybean life, two soybean seedlings with the same growth status are taken, one of them is cultured in magnesium-containing culture medium and the other is cultured in (). A. Pure water B. Sand without sand. Water containing only magnesium. Media containing no magnesium
- Biological control experiments were the only variable experiments. The question that is being explored is the variable, and the other quantities are the same. In a different amount (conditions) the same circumstances to modify a data variable in order to get the data variables on the experimental changes in the law. In order to prove that magnesium is essential for the life of soybeans, the variable is the presence or absence of magnesium. Can be designed as a magnesium-containing culture medium and magnesium-free culture medium. The other amount of the same as the amount of culture medium, soybean seedling growth status, the same number, while placed in the same place, etc., to ensure that only one variable that is the presence of magnesium.
- Q: I tried sodium and potassium carbonate and had little luck. Anyone know where to find the solubility data of inorganic salt in DMF?Thanks.
- Sodium and potassium carbonate WILL dissolve in DMF. The best way to dissolve them is to... a) dry the solid inorganic salt in an oven (> 100 degrees C) overnight. b) pulverize the powder and grind several minutes with mortal and pestle. c) sonicate the mixture for several minutes...
- Q: What is the relationship of electronegativity and the solubility of a inorganic salts?Does the solubility increase when electronegativity decreases or vice-versa? or neither...
- The higher the electronegativity, the stronger the acid would be... Therefore it would be more soluble. take NaCl (common table salt) as an example. The difference between Na's electronegativity and Cl's electronegativity is very high so NaCl is a very soluble salt. The only exception is HF - it is a weak acid - it dissociates very weakly because O-H bonds cannot break H-F bonds which are very strong.
- Q: What is the risk of low inorganic salt?
- Phosphorus into the body of phosphorus containing 750-800mg about 1% of body weight, mineral weight of 1/4. Of which 87.6% in the form of hydroxyapatite bone salt stored in the bones and teeth, 10% with protein, fat, sugar and other organic matter combined constitute soft tissue, the rest distributed in the muscle, skin, nerve tissue and other tissues and membranes Of the ingredients. Function Phosphorus is present in every cell of the human body, which is indispensable for bone growth, tooth development, renal function and nerve conduction. Phosphorus is a component of nucleic acids, phospholipids and certain enzymes, which promotes growth and tissue repair. It helps carbohydrate fat and protein utilization, regulates glycogen breakdown, and participates in energy metabolism. Phospholipids are the major components of the cell membrane, which are related to the permeability of the membrane. Phosphate can regulate the metabolism of vitamin D, to maintain the stability of calcium within the environment. Lack of disease phosphorus deficiency when the mental confusion, cranial nerve palsy, transport disorders, muscle weakness, hypothyroidism, anorexia, joint stiffness, abnormal blood, urinary calcium increased. Typical cases hyperphosphatemia, renal dysfunction, or hypoparathyroidism and hypothyroidism and other endocrine diseases can also occur. Too many symptoms nerve excitement, tetany and convulsions. The physiological requirement of phosphorus is 12.3mg / kg / d. Calcium / phosphorus ratio in the 2: 1-1: 2 appropriate range. Food sources food in the meat, fish, milk, beans and hard shells and other phosphorus more.
- Q: RO reverse osmosis water machine can remove impurities in the water, that the body will not be due to lack of minerals and malnutrition?
- Early society has not yet entered the era of industrial development, then the life of drinking tap water pollution, but also relatively clean, in the case of completely pollution-free, of course, stored in the water only a trace of beneficial minerals on the human body, through our daily life But now the industrial development, destruction of our water, we can not for the slightest beneficial to the human body of minerals, and to absorb a lot of harmful substances in the body it! Moreover, the minerals in the water and the water in the water, Is not the main source of human needs, we can get from the daily diet of the human body needs 99.9% of the minerals, water contains organic matter, inorganic matter is not necessarily absorbed by the human body, or even harmful is not necessarily.
