Asolution contains 0.1 (10-7) moles of hydroxyl ions (oh-) per liter. which of the following best describes this solution? a solution contains 0.1 (10-7) moles of hydroxyl ions (oh-) per liter. which of the following best describes this solution? basic: h+ donor basic: h+ acceptor acidic: h+ acceptor neutral acidic: h+ donor

neutral

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.

Putting in the values:

Thus as pH is equal to 7, the solution is neutral and nether accepts nor donates .

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

your answer would be “dry”
