Predict the products of the following acid-base reactions then balance the equations.?

Question

HF+KOH
HNO2+NaOH
Ca(OH)2+H2CO3

That's how it's written on here. HNO2
I suck at chemistry as well...but it's a main focus in my science class blahh.

Answer 1

HF+KOH > KF + H2O
HNO2+NaOH > NaNO2 + H2O
Ca(OH)2+H2CO3 > CaCO3 + 2H2O

HNO2 is not incorrect. I believe it is called nitrous acid. The NaNO2 is called sodium nitrite and is found in some meats such as bacon.

Answer 2

Remember that one of the products is always water (OH from the base) +(H from the acid).

Answer 3

initially the equation for the acid-base neutralization reaction is: HCl + NaOH > NaCl + H20. this could be a quite elementary subject so i think of you're over thinking it! :) Now you understand which you initiate with .5M of HCl, and .5M of NaOH. .For this equation there is .5 moles of water produced. to help illustrate this i visit establish a ratio: .5 moles of NaOH * I mole of Oxygen/a million mole of NaOH = .5 moles of oxygen. meaning that there is .5 moles of oxygen produced throughout this reaction. understanding this you could evaluate it to a single mole of H20. a million mole of H20 * a million mole of Oxygen/a million mole of H20 = a million mole of oxygen. i understand that there is one mole of oxygen in one mole of H20 via fact of its subscripts and coefficients. contained in terms of hydrogen there are 2 moles of hydrogen in line with mole of water. Does that make experience? The coefficients and subscripts inform you the way many atoms of each element are present day in a compound, and from that expertise you could set up ratios. So in one mole of water you have one mole of oxygen. So in case you have .5 moles of oxygen, like I calculated interior the 1st equation, you've gotten .5 moles of H20. i desire it rather is clever, and robust luck.

Answer 4

you wrote clorhidric acid's formula wrong, it is HNO3.

and I wasn't very good in my chemistry class , but good luck.
