Percent yield is 23.11 % when 162.8 g of CO2 are formed from the reaction of excess amount of C8H18 and with 218.0 grams of O2.
Explanation:
Balanced equation for the chemical reaction:
2C8H18 + 25O2 → 16CO2 + 18H2O
data given:
CO2 formed (actual yield) = 162.8 grams
mass of oxygen = 218 grams
16 moles of CO2 formed when 5 moles of oxygen reacted
3.6 moles of CO2 formed when 6.8 moles of oxygen reacted.
In the reaction 16 moles of CO2 will have 44.01 x 16
theoretical yield of CO2 = 704.16 grams
percent yield = 
x100
putting the values in the above equation
percent yield = 
x 100
= 0.23 x 100
= 23.11 %
Percent yield is 23.11 %.
Answer:
Climate change leads to a loss of species
With these changes, species have to adapt to new climate patterns (variations in rainfall; longer, warmer summers etc). ... The consequences include habitat loss; shifts in climatic conditions and in habitats that surpass migrational capabilities; altered competitive relationships.

Thank you
Answer:
re-do test if needed
Explanation:
if you're done early for the practical, check your answers back to the solutions. If feel the need to re-check if the answers are somewhat correct, re-do the steps :) all the best!
Heterogeneous mixtures are not similar throughout. Milk, the cake mix and smoothie are homogeneous mixtures because they have a uniform consistency throughout.
The only answer in this is D) mixed nuts.
Hope this helps! :)
