In an experiment ,100g of aluminium is burnt in oxygen ,giving aluminum oxide ,150 g of aluminium oxide is obtained .What is the % yield for the experiment ? (If you need any formulas ask me and i will answer, i just really need help ;/ )

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.

it is a solid

explanation:

b) nuclear ive learned that in a pedtrodic table
