Fe2 O3 + 3 H2 ------------->2 Fe + 3 H2 O Calculate how many moles of iron can be made from16.5 grams of Fe2 O |
|
Answer» ong>Explanation: SINCE there is already a balanced chemical equation. Convert grams of FE2O3 GIVEN into moles by dividing 16.5 grams by the atomic mass of Fe2O3 16.5÷159.59=0.103 moles Set the molar ratios of the reactant in question which is Fe2O3 to the product which is Fe. 1 :0.103 2 : X (the X is the unknown moles of Fe cross multiplying will GIVE X=0.206. therefore the number of moles of Fe is 0.206 however we want mass of Fe so MULTIPLY the number of moles by the atomic mass of Fe which is 55.845g/moles so 0.206x55.845= 11.5 grams of Fe produced |

At which stage plasticizers are added to polymers? |
|
Answer» are Plasticizers? TAGS: PVC, Plasticizers and Sustainability Selecting Plasticizers for PolymersPlasticizers are relatively non-volatile organic substances (MAINLY liquids). When incorporated into a plastic or elastomer, they help improve the polymer's: Flexibility Extensibility and, Processability Plasticizers increase the flow and thermoplasticity of a polymer by DECREASING the viscosity of the polymer melt, the glass transition temperature (Tg), the melting temperature (Tm) and the elastic MODULUS of the finished product without altering the fundamental chemical character of the plasticized material. Use of Plasticizers Plasticizers are among the most widely used additives in the plastic industry. They are also usually cheaper than other additives used in polymer processing. Plasticizers are most often used in PVC, the third largest polymer by volume after PP and PE. In turn, PVC is used in a wide range of products. Examples include: Unplasticized PVC (or rigid PVC) is used in applications such as pipes, siding, and window profiles. Plasticized PVC (or flexible PVC) finds applications in automotive interior TRIM, cables, PVC films, flooring, roofing and wall coverings, etc. |
