- Q: CuMnFeNior ZnAlso metal calcium reacts with molecular hydrogen to form a compound. Which statement concerning this compound is not true?It's formula is CaH2it is ionicsolid at room tempwhen added to water, reacts to produce h2 gaswhen added to water, forms acidic solutionMy guess was going to be that it is not ionic, but i'm not 100% positive.Can anyone help me with these chemistry questions? Or atleast point me to some webpage that might help. Please and thank you.
- Only Zn compounds form colorless or white salts. The second question would be the last answer, which is false. It forms an alkaline solution when added to water.
- Q: Does the inorganic salt fight the mass spectrum?
- Can it be specific? What mass spectrometer, which inorganic salts. Do EI need samples can be vaporized, inorganic salts obviously not appropriate
- Q: Why is the residue after burning known as coarse ash? And inorganic salt content What is the difference
- There is no essential difference, the measurement method is different, so the result is different, the former is the burning method, which is the chemical method or instrument method
- Q: How much of the body's inorganic salts account for the weight of the body?
- The inorganic salts in the human body account for about 5%
- Q: What fruit contains more minerals?
- Strawberry nutrient-rich, rich in a variety of active ingredients, per hundred grams of fresh fruit with vitamin C60 mg, than the apple, grape content is also high. Flesh contains a lot of sugar, protein, organic acids, pectin and other nutrients. , Strawberry is also rich in vitamins B1, B2, C, PP and calcium, phosphorus, iron, potassium, zinc, chromium and other essential minerals and some trace elements. Strawberry is the body of the necessary cellulose, iron, potassium, C and flavonoids and other important sources of ingredients.
- Q: Definition of inorganic salts
- In addition to hydrogen, oxygen, nitrogen, carbon, sulfur, organic compounds other than organic compounds are collectively referred to as inorganic salts. The inorganic salts required by the human body, according to the content in the body, divided into essential elements (hydrogen, oxygen, nitrogen, , Magnesium, phosphorus, chlorine, potassium, sodium 11) in the human body content, the need for larger also known as macro elements of the source 2, the rest of the various elements, regardless of content, can be collectively referred to as inorganic salts. More elements such as iron, magnesium, potassium, sodium, phosphorus, sulfur, chlorine and other elements, other elements such as iron, copper, iodine, zinc, manganese, drilling, etc., due to the existence of a small number, and some even trace Known as trace elements, 3, what is the "inorganic salt", the body contains elements in addition to carbon, hydrogen, oxygen three elements mainly in the form of organic matter, the rest of the various elements are in the form of inorganic matter, collectively referred to as inorganic Salts such as calcium, magnesium, potassium, sodium, phosphorus, scratch, sulfur and the like
- Q: What are the important physiological functions of inorganic salts in cells
- Inorganic salts are important for the structure of tissues and cells. Hard tissues such as bones and teeth are mostly composed of calcium, phosphorus and magnesium, and soft tissue contains more potassium. The inorganic salts in the body fluids regulate the permeability of the cell membrane, control the moisture, maintain normal osmotic pressure and acid-base balance, and help transport the common elements to the whole body, participate in nerve activity and muscle contraction. Some are inorganic or organic compounds that are involved in many important physiological functions of constituents, hormones, vitamins, proteins and nucleic acids that make up enzymes, or as activators of various enzyme systems. For example: to maintain the heart and brain activity, to help the formation of antibodies, play a useful role in the human body.
- 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: Effects of Minerals on Plants
- Minerals have a significant effect on plants, plants require about 25 elements, CHONPS Na Mg AL B MO Ca Fe Zn, etc. Most of these minerals have these elements, which are absorbed in the soil by roots and transported to plants Different parts, the role of a lot of plants lack of mineral leaves will be yellow, such as if there is no Mg, it can not be normal photosynthesis, because Mg is the necessary elements of synthetic chlorophyll, etc., if you want to know more profound, you can put each Kind of elements are checked.
- 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 ...
