Redox

100

What does OIL RIG stand for?

Oxidation is loss of electrons, Reduction is gain

200

Redox reactions involve the transfer of what?

Electrons

300

Which redox reaction is happening? Fe³⁺ + e --> Fe²⁺

Reduction - Fe gaining electrons

400

Which redox reaction is happening? Cl^2----> Cl + 2e

Oxidation, Cl is losing an electron

500

Cr⁺ + Sn⁴⁺ --> Cr³⁺ + Sn²⁺  What reactions are occurring. 

Chromium is oxidized since it is gaining electrons. Sn is being reduced since it is gaining electrons.

4.5 moles * 40 g = 180 grams

200

How many atoms are in 8.21 moles of Carbon?

8.21 moles * 6.022*10^23 = 4.944062*10^24

300

How many grams of carbon are in 3 moles of C₉H₁₉O?

3 moles of the molecule * 9 moles of carbon * 12 grams = 324 grams

This is the chemical reaction of photosynthesis - 

6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂. If I produce 32.6 grams of glucose (C6H12O6), how many grams of CO₂ did I start with? 

(32g glucose / 180.1g glucose) * 6 CO₂ * 44g = 47 grams of CO₂
