When magnesium chloride reacts with water, 5.85)l hclg is produced. how many moles of hcl is produced

650 moles

Explanation: so converted in grams just to make it easy for me, its 5850 g of water right, which is 325 moles of water

so here's the balanced equation

MgCl2 + H20 ==> 2HCl + MgO

thus 1 mole of h20 gives us 2 moles of hcl, so 325 x 2 = 650 moles of hcl

a polar bond is formed when electrons are shared unevenly between atoms
