Answer:
A
Explanation:
asteroids most often leave trails due to the large amount of friction that occurs.
percent by mass of carbon = 27,27 %
percent by mass of oxygen = 72.72 %
Explanation:
To calculate the percent composition of carbon dioxide (CO₂) we use the following algorithm.
Molecular mass of CO₂ = atomic weight of carbon × number of carbon atoms + atomic weight of oxygen + number of oxigen atoms
Molecular mass of CO₂ = 12 × 1 + 16 × 2 = 44 g / mole
Considering 1 mole of CO₂ we devise the following reasoning:
If in 44 g of CO₂ we have 12 g of carbon and 32 g of oxygen
Then in 100 g of CO₂ we have X g of carbon and Y g of oxygen
X = (100 × 12) / 44 = 27,27 % carbon
Y = (100 × 32) / 44 = 72.72 % oxygen

Explanation:
What are the two oxidation states of sulphur in sodium thiosulphate ? In thiosulphate, two sulphurs have oxidation state of -2 and +6. (as per suggestions). Sulphur bonded to three oxygen is considered to have +6 (Sulphur A) and other sulphur has -2 (Sulphur B).
C. Metal oxide reacting with coke in a high temperature because I don’t think it reacts with coke during metal smelting (not 100% sure though)
Answer:
$474.30
Explanation:
23.25 × 102 = 2371.5 (total amount of money produced from pallets)
2371.5/5 = 474.3 (payout per worker)
