Answer:
True
Explanation:
Ex. People against vaccines tend to believe crazy theories over facts because they think they'll end up brainwashing them.
Plant cells are affected as they begin to wilt and reduce photosynthesis
Answer: -
O 2 limiting reagent
53.83 g CO2 theoretical Yield
97.9% percentage yield
Explanation: -
Mas of CH4 = 23.2 g
Molar mass of CH4 = 12 x 1 + 1 x 4 = 16g
Mass of O2 = 78.3 g
Molar mass of O 2 – 16 x 2 = 32 g
The balanced chemical equation for the reaction is
CH4 + 2 O2 = CO2 + 2 H2O
From the balanced equation we see that
2 O 2 reacts with 1 CH4
2 x 32 g of O 2 react with 16 g of CH4
78.3 g of O 2 react with

= 19.575 g pf CH4
Thus CH4 is in excess.
The limiting reagent is thus O 2.
Molar mass of CO2 = 12 x 1 + 16 x 2= 12 +32 = 44g
From the balanced equation we see
2O 2 gives 1 CO2
2 x 32 g of O 2 gives 44g of CO2
78.3 g of O 2 gives =

=53.83 g of CO2
Theoritical Yield = 53.83 g of CO2
Actual yield = 52.7 g
Percentage yield =

=97.9 %
