Q:What is the common substance oxide in junior middle school chemistry

Elemental: chlorine, hydrogen, oxygen, nitrogen, sulfur, carbon, phosphorus, aluminum, potassium, sodium, magnesium, iron, silver, copper, zinc and so on.

Q:are there any other foods than water and salt that have an abiotic origin (lifeless, inorganic)?

Various minerals we need, like iron, zinc, magnesium, etc. That's it. These also are not technically foods, as the first poster said.

Q:as a example potesium,sodium,magnees,calcium

The sodium-potassium pump is most important in controlling the working of neurotransmitters. Calcium ion is also generated in voltage gated Ca++ channel, and Magnesium is necessary for metabolic functions. But Sodium is one of the most important inorganic component in our body. Of course Potassium is also as important. But, if you have ever seen the back of all food products there is a special part showing amount of Sodium in it...even Snacks.. :)

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 is the time when the maximum number of inorganic salts is needed

Seedling stage requires the largest amount of inorganic salts, because the seedling period is to lay the foundation for the growth period, in the strong growth period is mainly composed of synthetic organic matter.

Q:What is white alkali?

White alkali is dough (soda, soda ash), scientific name sodium carbonate, chemical formula Na2CO3.

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: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: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.

Q:For example, sulfates can emit SO2 or SO3 gas. If this were to occur in this experiment, would the % H2O calculated from the data be too high or too low? Explain.

You would measure the mass lost, and you would assume that this is equal to the amount of water that was in the sample. So decomposition would add to the mass lost during heating and this would lead you to overestimate the amount of water that was in the sample, and overestimate the %h20.
