Q: Why does not the base noodles rub?: May add too much water. Noodle black is caused by alkali, you can use the source of gluten instead of edible alkali.

Q: Diamond, graphite is a simple element?: Is the elemental, chemical formula is C, is the carbon allotrope

Q: What foods contain zinc-containing inorganic salts: No. 4: Chibi (11.58 / 34g / 100g)

Q: What are minerals and trace elements?: 81 species were detected on the basis of the human body. 81 kinds of elements in the body of the arrangement is very tight combination, and more less will not work. Human anatomy found that there are 74 kinds of serum, 54 kinds of brain, 49 kinds of heart, 50 kinds of liver, thymus 18 species. They constitute the most basic unit of the human body, human life, old, sick, dead and all elements related to the body. According to the elements in the human body content is different, can be divided into macro elements and trace elements two categories. Accounting for more than 0.01% of the total body weight of the elements, such as carbon, hydrogen, oxygen, nitrogen, calcium, phosphorus, magnesium, sodium, etc., called macro elements; , Zinc, copper, manganese, chromium, selenium, molybdenum, cobalt, fluorine, etc., known as trace elements. Trace elements in the human body content is really minimal, such as zinc only the total weight of the human body of thirty-three parts per million. Iron is only sixty thousandths.

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: The inorganic salt is composed of?: Inorganic salts are the general term for various inorganic salts. They are composed of inorganic acid radicals and metal cations or ammonium salts, mainly salts of organic acid salts, such as sodium chloride, potassium chloride and so on.

Q: Which minerals is richest source of Inorganic Salts ?: Minerals are inorganic salts - eg.potassium nitrate - absorbed by plants from soil - a good source of inorganic nitrogen and potassium.

Q: A. food gathering and digestion B. photosynthesis and diatom structures C. reproduction and osmosis D. wave and current motions: its not a so try b or c those 2 are the most likely to be the right answers

Q: The addition of inorganic salt viscosity of micelles increased first and then increased again and then reduced, there is no possibility ah? Yes, then what is the reason for the increase ah?: possible. The inorganic salt is dissolved in water to form positive and negative ions, and the ions of the micelles are extruded to make the solubility smaller and form an increase in the viscosity. With the increase in the amount of inorganic salt, it does not have the ability to dissolve in water, there is no micelles and the molecular state exists in the water, the liquid becomes thin ...
