Which best describes an acid?

An acid is a material that can deliver proton or hydrogen (H+) Its particle or ion capable of giving a hydron

Explanation:

It's not my exact answer I used google

A chemical substance that neutralizes alkalis, dissolves some metals, and turns litmus red; typically, a corrosive or sour-tasting liquid of this kind.

Explanation:

An acid is a material that can deliver a proton or hydrogen ion (H +). Hydrogen chloride in water suspension ionizes and converts to hydrogen ions and chloride ions. An acid is a particle or ion capable of giving a hydron (proton or hydrogen ion H+), or, alternatively, able of creating a covalent bond with an electron pair (a Lewis acid). The first level of acids is the proton donors or Brønsted acids.

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

the answer is b ) square root of 5
