- Q: TRUE OR FALSE: the addition of salts to water will always increase the surface tension of water. explain.?
- False. Although inorganic salts will increase surface tension of the water by increasing the attractive forces between water molecules on the surface, organic salts will typically (always?) decrease the surface tension.
- Q: I'm said that with the increase of temperature the inorganic salts will decrease. Will that be correct?
- Usually solubility will increase with increasing temperature but there are a significant number of exceptions which show the opposite.
- 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: Recently felt the whole body are sore, is not the relationship between the movement?
- Need to exercise: a reasonable exercise can speed up the blood circulation, improve the rate of metabolism.
- Q: Last called me to buy salt, but can buy a bag of alkaline powder to go home. Want to know what can use alkali powder?
- In addition to medicinal function, alkaline powder also has a strong decontamination function. I brought a cup full of dirt, rinse with water, and then rubbed and rubbed by hand, but the dirt or tightly stick the cup. I add detergent, but also hard to rub, or stubborn dirt still still motionless. I sprinkled with alkaline powder, rubbing the side of the water gently rubbing the cup, those dirt seems to be afraid of alkaline powder like all fled, and soon the cup becomes smooth as new!
- Q: What is a compound?
- The compound is a pure substance consisting of two or more different elements. The different atoms that make up the compound must be present in a certain proportion, in other words, the compound has a certain composition regardless of the source. In daily life, sodium chloride, and distilled water (water), are common compounds. From these compounds, it is found that their properties are different from each other, the salt is composed of sodium atoms and chlorine atoms; sugar is composed of carbon, hydrogen and oxygen atoms; hydrogen in the combustion of oxygen reaction generated water. These facts indicate that two or more substances can react to produce a new substance, which is the compound. The nature of the new material is completely different from the nature of the substance. Usually chemically in this way to determine whether the nature of the compound is a compound. And if a pure can be broken down into two or more than the quality of the original quality of the compound. Such as molten salt, through the current, can be completely broken down into sodium and chlorine atoms, so the salt as a compound.
- 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: Does the lack of inorganic salts cause convulsions?
- The lack of important substances in the salt body is indeed the use of salt to protect the health of important substances than the calcium and phosphorus main body bone calcium blood coagulation muscle contraction and nerve cell regulation very important phosphorus calcium with the same function of food are preserved phosphorus body lack of calcium muscle spasms Can be rash dyspnea gastrointestinal paralysis and other body no phosphorus calcium calcium phosphate can be used to make bone calcium and phosphorus with a reasonable reason to play its role in the use of salt my body's non-essential body about 50 grams of salt according to 0 --- 2 5 grams To follow the excreta outside the body need to be added or otherwise the body of the production capacity of the body is extremely lack of salt can be fainting disease to speed up or even cause muscle weakness in the iron content and its role is not important in vivo iron deficiency anemia and other iron deficiency
- Q: Recently, when I breathe feeling a bit of acid teeth, this feeling particularly uncomfortable, ask you what is the reason ah? What should I do? Thank you
- Or to the hospital to find a dentist point desensitizer desensitization cream to the fast.
- Q: Inorganic salt is not salty
- HCl (hydrochloric acid) dilute: more acid, feeling slippery mouth, the typical vomit feeling, slightly spicy. Concentration: extreme acid, spit after the bitter taste, and then the whole mouth cold, 10 minutes later improved.
