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: The effect of inorganic salt medium and the difference with enrichment medium
- The enrichment of nutrients is based on the basis of nutrition based on some kind of nutrient-rich substances for the target cells, the purpose is to increase the number of target cells, so that the formation of growth advantages, so as to achieve the purpose of separation, such as we have to be separated Pseudomonas aeruginosa, this bacteria particularly like blood, so you can add blood in the medium, so that the formation of growth advantages of this bacteria.
- Q: What is an inorganic salt?
- Encyclopedia is defined as: inorganic salts that inorganic compounds in the salt
- Q: Where are the parts of the bryophyte absorb water and inorganic salts?
- Moss moss moss, moss Gang, moss root through the fake root absorption, that is, the use of cell penetration technology, moss Gang has evolved out of the root, so you can directly through the relatively low roots to absorb Oh
- Q: What is the most important inorganic salt in plant growth?
- The inorganic salts required by plants are nitrogen, phosphorus and potassium containing inorganic salts, and if any lack of plants will affect the normal growth of plants, nitrogen is a component of many important organic compounds in the body, such as protein, nucleic acid, chlorophyll , Enzymes, vitamins, alkaloids and some hormones contain nitrogen. Nitrogen is also the basis of genetic material in all organisms, the most important protein, it is often in the center of metabolic activity.Now is to limit the growth of plants and the formation of the primary Factor. It also has a significant effect on improving the quality of the product.K2 is dissolved in the plant juice, and its main function is related to the metabolism of the plant.The content of phosphorus in the plant is second only to nitrogen and potassium, Phosphorus plays an important role in plant nutrition. Almost all important organic compounds in plants contain phosphorus. Phosphorus is involved in photosynthesis, respiration, energy storage and delivery, cell division, cell enlargement and other processes in plants.
- Q: how come a penny can hold more drops of the salt water solution than just plain tap water from your faucet?
- Surface film tension is the property of a liquid by which it acts as if its surface is a stretched elastic membrane. This tension allows insects to stand on the water’s surface. Surface film tension is caused by the attraction of water molecules to each other; in addition, the surface molecules are attracted to the underlying molecules. The amount of surface film tension is affected by both temperature and dissolved substances. An increase in temperature lowers the net force of attraction among molecules and so decreases the surface tension. An increase in dissolved organic substances also lowers the surface tension However, an increase in dissolved inorganic salts causes a rise in surface tension - increases the attraction of the surface molecules for the underlying molecules.
- 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: List the major electrolytes released by inorganic salts when placed in water and explain how these electrolytes are needed for metabolic reactions.
- Which "inorganic salts" are you talking about? There are hundreds!
- Q: What is the use of inorganic salts and organic salts?
- The organics are compounds containing carbon, and the inorganic salts are salts containing no carbon. For example, we usually eat sugar is organic matter, salt is inorganic salt.
- Q: Think about the physical and chemical properties of salt and sugar. What properties do these substances have in common? Describe which properties you could use to distinguish between them. What properties and units would you use to describe their physical and chemical characteristics? List as many as you can.
- I believe it's Physical, most of the times such changes are physical, melting point, sublimation, evaporation, etc.
