10 strong acid and weak acid |
| Answer» \tStrong acids completely dissociate into their ions in water, while weak acids only partially dissociate.\tThere are only a few (7) strong acids, so many people choose to memorize them. All the other acids are weak.\tThe strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid.\tThe only weak acid formed by the reaction between hydrogen and a halogen is hydrofluoric acid (HF). While technically a weak acid, hydrofluoric acid is extremely powerful and highly corrosive. | |

What is Corps Callosum and Hypothalamus? |
| Answer» The\xa0hypothalamus\xa0is composed of several different areas and is located at the base of the brain. One important function of the\xa0hypothalamus\xa0is the\xa0control\xa0of body temperature. The\xa0hypothalamus\xa0acts as like a "thermostat" by sensing changes in body temperature and then sending out signals to adjust the temperature.\xa0The absence of the\xa0corpus callosum\xa0seems to\xa0affect\xa0the development of\xa0behavioral\xa0characteristics and cause specific\xa0behavioral\xa0anomalies. Taken together, evidence from previous studies with AgCC patients suggest that social cognitive impairments may relate to the missing\xa0corpus callosum. | |

Why are used alloy in heating device rather than pure metal |
|
Answer» It do not oxidised readily to high temp. Coils of electric toasters and electric irons are made of an alloy due to the followingreasons:i. Resistivity of an alloy is generally higher than that of pure metal.ii. At high temperature, an alloy does not oxidize readily. Hence, coil of an alloy has longer life. ?? |

Why curd not Store in copper vessels |
|
Answer» It can react with copper and make the curd poisones Because copper Will react with curd because curd is acidic in nature and due to this reaction some toxic materials are formed which are not suitable for eating Curd contains lactic acid. Generally, acids react with metals to form a different compound. Thus, the curd is not stored in metal containers of brass, copper, and bronze as curd can react with them and produce compounds which are toxic to human beings and unfit for human cons Curd contains lactic acid. Generally, acids react with metals to form a different compound. Thus, the curd is not stored in metal containers of brass, copper, and bronze as curd can react with them and produce compounds which are toxic to human beings and unfit for human consumption.

What corrosion |
|
Answer» Corrosion is a natural process, which converts a refined metal to a more chemically stable form, such as its oxide, hydroxide, or sulphide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment. Corrosion degrades the useful properties of materials and structures including strength, appearance, and permeability to liquids and gases. Corrosion is one of the most common phenomena that we observe in our daily lives. You must have noticed that some objects made of iron are covered with some orange or reddish-brown coloured layer at some point in time. The formation of this layer is the result of a chemical process known as rusting, which is a form of corrosion. The process of slow conversion of metals into their undesirable compounds by the action of components of air i.e. oxygen, moisture and other gases like SO2, NO2, etc. is known as corrosion. |
