Finally, add together the total mass of each element to get the molar mass of Mg3 (Si2O5)2 (OH2): 72.915 g/mol + 112.342 g/mol + 175.9934 g/mol + 2.01588 g/mol = 363.26628 g/mol. 5. Find Mole Fraction. To find the mole fraction and percentage of each element in Mg3 (Si2O5)2 (OH2), divide each total from step 3 by the total molar mass found in
سؤالStep 4: Substitute Coefficients and Verify Result. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Since there is an equal number of each element in the reactants and products of 2MgO + Si = 2Mg + SiO2, the equation is balanced.

سؤالThis assignment fits well with the chemistry of the binders produced within the Mg(OH) 2 –SiO 2 –H 2 O system studied; assuming complete reaction of Mg(OH) 2 and SiO 2 in these samples, the molar Mg/Si ratio of this binder should be ∼0.95.
سؤالStep 4: Substitute Coefficients and Verify Result. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Since there is an equal number of each element in the reactants and products of Mg2Si + 4H2O = SiH4 + 2Mg (OH)2, the equation is balanced.
سؤالSilicon–oxygen bond. A silicon–oxygen bond ( Si−O bond) is a chemical bond between silicon and oxygen atoms that can be found in many inorganic and organic compounds. [1] In a silicon–oxygen bond, electrons are shared unequally between the two atoms, with oxygen taking the larger share due to its greater electronegativity.
