How many types of hydrocarbon |
| Answer» \tSaturated hydrocarbons: They are the compounds in which carbon-carbon atoms and carbon-hydrogen atoms are held together by single bonds. These single bonded compounds are the simplest hydrocarbons. The general formula for these single bonded organic compounds is CnH2n+2.\tUnsaturated hydrocarbons: These compounds consist of a single, double or a triple bond between carbon-carbon atoms. The double-bonded compounds are called alkenes and the triple bonded compounds are called alkynes. The general formula for alkenes is CnH2n and for alkynes the general formula is CnH2n-2.\tCycloalkanes: These hydrocarbons possess one or multiple carbon rings. The hydrogen atom is attached to the carbon ring.\tAromatic Hydrocarbons: These are also called as arenes. Arenes are compounds which consist of at least one aromatic ring. | |

Answer» All surfaces of plants that are in the air have some stomata but leaf surfaces have the most because this is where photosynthesis is occurring. The underside of leaves have more stomata than the upper surface because less evaporation will take place in the cooler, shady underside of the leaf. For less transpiration For less respiration. |

Why is an aqueous solution of ammonium chloride acidic in nature |
| Answer» NH4Cl is a salt of strong acid and weak base. Cl- being a weak base will not hydrolyze in water.So when NH4Cl will dissolve in water following equilibrium takes place:NH4+ + H2O ↔ NH4OH + H+The solution will be acidic because of presence of H+ ions in solution.On the other hand CH3COONa is a salt of weak acid and strong base.The equilibrium will be as follows:CH3COO- + H2O ↔ CH3COOH + OH-The solution will be basic because of presence of OH-. | |

What is the potential difference between two points? |
|
Answer» The unit of potential difference generated between two points is called the Volt and is generally defined as being the potential difference dropped across a fixed resistance of one ohm with a current of one ampere flowing through it. In other words, 1 Volt equals 1 Ampere times 1 Ohm, or commonly V = I*R. W/q |

What is osmo regulation? |
| Answer» 1) Osmoregulation is the process of maintaining salt and water balance across membranes within the body.2) The kidneys are the main osmoregulatory organs in human body.3) They function to filter blood and maintain the dissolved ion concentrations of body fluids.4) The nephron is the functional unit of the kidney, which actively filters blood and generates urine.5) Hormones like antidiuretic hormone vasopressin and aldosterone used in the body to help to increase the permeability of the collecting ducts found in the kidney.6) This further allows diffusing to occur easily, it also allows the kidneys to be able to absorb water and prevent it from being excreted.7) Humans are also able to regulate by controlling the total amount of water that is passed out of the body through the urine or sweat.8) Absence of vasopressin hormone produces dilute urine. Hormone action maintains osmotic concentration of body fluids.9) Deficiency of vasopressin causes excessive, repeated, dilute urination. | |
