    @arjunbir154412 years ago Great video, I am pretty sure though, that to make calculations as you did, you must use a balanced reaction only, as the number of atoms of each element are equal on the products and reactants sides of a reaction only when it is balanced. Otherwise, great stuff. Thank you and keep it up. ...

    @radinelaj39323 years ago Hello professor , can I ask you a simple question : imagine if you put a quantity( amount) of water in a glass ( simple glass) , can you put this water in another glass ( I mean : to the extent of 100% of quantity of water ) , can you carry this amount of water( 100% of amount) in another glass ( to put all quantity of water in another glass( without losing any drop or molecule of water during the transportation) , can you do that ?
    I think If you would try it you wouldn't, if you do that then your law( or equation) would be correct. Same thing happens when water condenses, is impossible to transport( to be transported)all amount of water ( all molecules) during the cycle of condensation,( during the rain formation ),it mean : the matter is losing during the cycles
    verify the physics pls,

    @radinelaj39323 years ago A debate for the law of conservation of mass/ energy ,I watched a video about these laws in you tube and I asked to him :
    Hello professor , can I ask you a simple question : imagine if you put a quantity( amount) of water in a glass ( simple glass) , can you put this water in another glass ( I mean : to the extent of 100% of quantity of water ) , can you carry this amount of water( 100% of amount) in another glass ( to put all quantity of water in another glass( without losing any drop or molecule of water during the transportation) , can you do that ?
    I think If you would try it you wouldn't, if you do that then your law( or equation) would be correct. Same thing happens when water condenses, is impossible to transport( to be transported)all amount of water ( all molecules) during the cycle of condensation,( during the rain formation ),it mean : the matter is losing during the cycles
    verify the physics pls,
    Someone reply to me :
    You need to distinguish between water being left behind and disappearing completely. As you transfer water from one glass to another you leave some behind so the original glass is wet , none of the water actually "dissapears"- matter is conserved . Same with the water cycle,, some water evaporates from the sea, but most remain as sea, some condenses as clouds, but some will remain as vapor ( gas) , some of the cloud will fall as rain but some remains as cloud- and so on. It's all there all the time
    Another ( someone) replied to me :
    That's incredible difficult, but you should know that the water you put in the glass will not go away. All of the contents in the first glass of water cannot be destroyed and the water cannot create any more water. It may change state( physically to ice or water vapour) but none of it will vanish, so technically it is possible to do this transfer a, and the law of conservation of mass is still correct.
    My rocket 🚀 reply was :
    My intention was to say : after a cycle the matter isn't turning back( at the extent of 100% )( all quantity, all molecules ,)
    By the way that is happening to the energy too, not only the matter is not turning back,but even the energy isn't turning back too ( as the matter isn't turning back too, so even the law of conservation of energy is not correct,
    These laws are atheists's laws, they are trying to say : we are eternal ,but that is not true.
    We're losing, friend ,matter is losing ,energy is losing,( everything is disappearing vanishing ,is losing)
    Were separating from energy,that is my law,
    Question : why energy is separating from the matter ? For example : sun is losing energy( heat or light ) where is going this energy ?! Are you saying : the energy will turn back ,it will conserve back into the matter ?; I doubt on it
    When I say : energy is losing I mean : is disappearing( vanishing) from our dimension ( our world)
    I can say another thing : if you transfer an amount of energy to another object ( from a battery to another) ,this energy will lose ( vanish ,disappear) anyway ,even you can transfer all energy ( all enectrons ,all atoms) ,it will lose (vanish) again ,or disappear( by casuality, spontaneously)
    The meaning is : you( all of you ) can conserve ,nothing can be conserved ,that is my law,
    For example : if you transfer energy from a battery to another battery ( from a power bank to a phone), the phone will lose its energy after four(teen)
    days ( even if you wouldn't use it ), with other words : energy will separate from matter( from battery), like the sun 's energy,it is separating from it( the sun). Everything is separating ,that's my law.
    I have made a post in f book about this case ,against atheists ,with simply words the point is : the matter and energy are joined together,question is : who joined them ( it) ?! For example : ,sun is made by energy and matter , the sun is losing energy ( heat , light ) , it mean : it was made by two things : energy and matter ,it was joined together ,question is : who joined together them ? There were a high intelligence energy who joined( welded ) them ,( God)
