How many grams of silver oxide are needed to react with 7.9 g of hydrochloric acid produce silver chloide and water?
Anastaziya [24]

Answer:

25.11 g.

Explanation:

  • It is clear from the balanced equation:

<em>Ag₂O + 2HCl → 2AgCl + H₂O.</em>

<em></em>

that 1.0  mole of Ag₂O reacts with 2.0 moles of HCl to produce 2.0 mole of AgCl and 1.0 moles of H₂O.

  • 7.8 g of HCl reacts with excess Ag₂O. To calculate the no. of grams of Ag₂O that reacted, we should calculate the no. of moles of HCl:

<em>no. of moles of HCl = mass/atomic mass</em> = (7.9 g)/(36.46 g/mol) = <em>0.2167 mol.</em>

  • From the balanced equation; every 1.0 mol of Ag₂O reacts with 2 moles of HCl.

∴ 0.2167 mol of HCl will react with (0.2617 mol / 2 = 0.1083 mol) of Ag₂O.

<em>∴ The mass of reacted Ag₂O = no. of moles x molar mas</em>s = (0.1083 mol)(231.735 g/mol) = <em>25.11 g.</em>

1- Oil Spill Pollution Problem Statement (it is written in the form of a question)
anastassius [24]
Oil spill pollution is happening today as we speak. Fracking is one main cause of this oil spill. Sometimes airplanes load oil and dump it in the oceanic ocean and it’s really sad to hear of so.

If this continues to happen, ocean life will decline and key stone species will die meaning the whole biosphere will colapse
