If 0.600 gram of zinc is used, what is the amount of zinc chloride that is produced in the above reaction?

 The solution would be like this for this specific problem:

Zn + 2HCl --> ZnCl2 + H2 

Molar Mass Zinc - 65.38 g/mol 
Molar Mass Zinc Chloride - 136.38 g/mol 
Number of moles of zinc reacting = 0.600 g / 65.38g/mol = 0.00918 moles 0.00918 moles * 136.38 g/mole = 1.25 g ZnCl2 

Answer = 1.25 grams of zinc chloride

I hope this helps and if you have any further questions, please don’t hesitate to ask again.

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.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
