Se tiene piedra caliza, cuyo contenido principal es el carbonato de calcio en un 72%. Se hace reaccionar este material con acido clorhídrico Cuanto cloruro de calcio se obtendrá si se parte de 200 g de CaCO3 CaCO3+ HCI. --> CaCl2 +CO2 +H2O

221.76 g
Or
1.998201 moles
Divide the 200 grams by molar mass of CaCO3 and multiply by the mole ratio of CaCO3 and CaCl2 to get the moles.
To get the mass, multiply the moles by the molar mass on the periodic table.

In meteorology, a  cloud  is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body. nephology is the science of  clouds, which is undertaken in the  cloud  physics branch of meteorology.cirrus clouds  usually describe clouds high in the atmosphere that can include wispy clouds, typically with ice crystals. variations include cirrus, cirrocumulus and cirrostratus as defined by the cloud's position in the atmosphere.layered stratus clouds  have both flat tops and bases, and can appear as if they take up the whole sky, stretching from horizon to horizon. other combinations and variations include stratus, stratocumulus, nimbostratus and altostratus.cumulus clouds  often pile up in multiple layers of the atmosphere, representing clouds that develop vertically. cumulus clouds often look like pillars with anvil-type tops or columns of clouds stacked vertically. variations include cumulus, cumulus-congestus, cumulonimbus and altocumulus.
