Please help me, my professor hasn’t taught us this. When chemicals are introduced into reaction in solution, we need to manage the stoichiometry by means of concentration.
We generally combine liquid solutions together by volume, but within those volumes the concentration could be anything
So when we balance the stoichiometry of liquid solutions we have to determine the number of MOLES.
I possess 0.900 liters of 1.000 MH, SO.
How many moles of Sulfate ions, 50, (aq) do I have to work with?
(Liters)(mol/Liter) = mol
How many moles of Hydrogen ions do I have to work with?
H2SO4(aq) → 2H*(aq) so, (a)
(There are twice as many H' as there are so lons.)

Afamily is one another name for a group on the table of elements.

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.
