A 55.0 grams sample of strontium arsenite is mixed with 65.0 grams of chromic acid in a double replacement reaction form strontium chromate and arsenous
acid. After the reaction was performed, 45.7 g of the actual strontium chromate
were collected.
a. Determine the limiting reactant.
b. Determine the excess reactant.
c. Determine the theoretical yield of Strontium Chromate in grams.
d. Determine the amount of excess reactant left over in grams
e. Determine the percent yield of strontium chromate.

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.

i do not get it   at all

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
