Balance the following Equation Show your work. Take a picture of it, and attach it to this document. 1.Ca2Si + Cl2 → CaCl2 + ___SiCl4

2. ___Ba(ClO3)2 → ___BaCl2 + O2

3. ___Al + ___Cu(SO4) → Al2(SO4)3 + ___Cu

4. ___Al + ___F2 → ___AlF3

5. ___MgO + ___O2 → ___MgO

6. __AgNO3 + __AlCl3 → __AgCl + __Al(NO3)3

7. ___Al + ___Fe2O3 → ___Fe + ___Al2O3

8. ___NH3 + __O2 → __NO + __H2O

9. ___C3H8 + ___O2 → ___CO2 + ___H2O

10. ___ZnS + ___O2 → ZnO + ___SO2

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

the answer is 0.8m.
