They both are caused by quakes in the bottom of the ocean or moves in tectonic plates, so they are caused by giant forces moving other giant land masses.

Earthquakes are when the tectonic plates hit each other and volcanic eruptions are when the plates push up against each other and release the magma below the estates crust

Answer:

Glucose and oxygen are required for cellular respiration. As the law of conversation states, in a biochemical reaction, mass is conserved. The mass of hydrogen in the glucose is therefore conserved in the water molecules products.

Consider the following Reaction.
Evgen [1.6K]

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 \frac{16 g CH4 x 78.3 g O2}{2 x32 g O2}

= 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 = \frac{44 gCO2 x 78.3 g O2}{2 x 32 g O2}

=53.83 g of CO2

Theoritical Yield = 53.83 g of CO2

Actual yield = 52.7 g

Percentage yield = \frac{52.7 g}{53.83 g} x 100

=97.9 %
