Answer:
Potassium Dichromate is an orange to red colored, crystalline, inorganic compound that emits toxic chromium fumes upon heating. Potassium dichromate is highly corrosive and is a strong oxidizing agent. This substance is used in wood preservatives, in the manufacture of pigments and in photomechanical processes, but is mainly replaced by sodium dichromate. Potassium dichromate primarily affects the respiratory tract causing ulcerations, shortness of breath, bronchitis, pneumonia and asthma but can also affect the gastrointestinal tract, liver, kidneys and immune system. This substance is a known human carcinogen and is associated with an increased risk of developing lung cancer and cancer of the sinonasal cavity. (NCI05)

<h2>The number of moles of formaldehyde can be produced by reacting 4.0 moles of methanol with 4.0 moles of oxygen gas is
<u>
8 moles</u></h2>
<u> explanation</u>
write a balanced chemical reaction
that is 2 CH3OH (l) + O2 (g) → 2HCOH (l)+ 2H2O (l)
from the reaction above 2 moles of CH3OH reacted with 1 moles of O2 to form 2 moles of HCOH and two moles of H2O
This imply that O2 is the limiting reagent ,therefore by use of mole ratio between O2 : HCOH which is 1 :2 the moles of HCOH= 2 x4 = 8 moles
