Calcium hydroxide and hydrochloric acid react to form calcium chloride and water as shown in the chemical reaction. if the chemicals are present in exactly the correct ratios to fully use all of the ingredients, how many moles of water would be formed from 5 moles of hcl? (oh)2 + ? +

5.0 moles of water will be produced from 5.0 moles of HCl.

Explanation:

The balanced equation is: 2 Ca(OH)₂ + 4 HCl → 2 CaCl₂ + 4 H₂O.From the stichiometry of the balanced equation, it is clear that 4.0 moles of HCl will result in 4.0 moles of H₂O that the ratio between them is (1 : 1).So, 5.0 moles of water will be formed from 5.0 moles of HCl.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
