State law of conservation of masshenejeneehheeu |
|
Answer» The law of conservation of mass or principle of mass conservation states that for any SYSTEM closed to all transfers of matter and ENERGY, the mass of the system must remain CONSTANT over time, as the system's mass cannot change, so quantity can neither be ADDED nor be removed. THEREFORE, the quantity of mass is conserved over time. |

Water, after turning into hydronium ion,still has one lone pair electron left.So, can it pair with one more H+ ion?If no, why? |
|
Answer» tion:Hydronium ions form in an effort to delocalize charge. if there is excess H+ in an aqeuos solution, then you will have proximity between H2O and H+. H+ is a very localized positive charge. H2O in proximity has two electron groups extending out into the space around it. The two extra electron groups of two electrons each combined with the two bound hydrogens in H2O make a tetra shape (kind of LIKE a triangular pyramid with the points being the direction of the electron groups) So due to the electromagnetic forces involved it is a lower energy state (and therefore preferred/more stable) for the H+ to associate with ONE of these electron groups instead of being free FLOATING, which makes for less localization of the positive charge. Or to put it another way, because molecular thermodynamics SAYS so. |

8. Explainwhy does conductivity of germanium crystals increase on doping with galium. |
|
Answer» okExplanation:On doping GERMANIUM with gallium, some of the crystal sites are occupied by gallium atoms. Three ELECTRONS of gallium are USED for making bonds with germanium while the 4th electron of germanium remains unbounded and THUS is FREE for movement and increases the conductivity of crystal. |

What is the difference between the nitrogen and helium? |
|
Answer» Nitrogen is considered a SLOW CARRIER gas with an optimum of 11–13 cm/sec. Helium is about 2 TIMES faster and HYDROGEN is the fastest gas. Because of concerns of SAFETY and reactivity, hydrogen is often avoided and helium is the preferred carrier gas.Explanation:This may help you ☺️Thank you |

What is the effect of pressure and temperature in the solubility of gas in liquids? |
|
Answer» Liquids and solids exhibit PRACTICALLY no change of solubility with changes in PRESSURE. Gases as MIGHT be expected, INCREASE in solubility with an increase in pressure. Henry's Law states that: The solubility of a GAS in a liquid is directly proportional to the pressure of that gas above the surface of the solution |

Electronic contrifugation of chlorine |
|
Answer» The p orbital can hold up to SIX electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll PLACE the remaining FIVE electrons. Therefore the Chlorine electron CONFIGURATION will be 1s22s22p63s23p5. |

Describe the affect of removal of H2 |
|
Answer» according to Le - Chatelier's principle, it states that a change in any of the factors that determine the equilibrium conditions of a SYSTEM will cause the system to change in such a manner so as to reduce or to counteract the effect of the change .after applying the rules , we get (a) addition of H2 ( increasing concentration of reactants ) MEANS equilibrium shifts forward direction ( hence, more PRODUCTS is formed )(b) addition of CH3OH : increases in concentration of products ) means equilibrium shifts the backward direction.(C) REMOVAL of CO : if we remove the CO then equilibrium shifts the backward direction.(d) Removal of CH3OH : equilibrium shifts in forward direction. |

СН3-СН2-СН-СН3 ОНIUPAC NAMEof this compound |
|
Answer» IUPAC name of the given compound is Butan-2-OL.Explanation: Let's solve thisSo we have four CARBON atoms that's why we will name the prefix as butan- but this compound has a FUNCTIONAL group of alcohol so we will use the suffix as -ol. In this case the functional group is attached to the second carbon atom so we will tell the position of the functional group at second carbon by indicating it as -2-ol.So the name comes to be Butan-2-ol. I hope that you are clear if not just text me a MESSAGE REGARDING your doubt and don't forgot to mark my answer as the brainliest. |
