Explain how it is possible for 10 grams of methane fuel to burn and emit 27 grams of carbon dioxide. Discuss whether or not this
Rufina [12.5K]

This reaction obeys the law of conservation of mass.

Explanation:

In the burning reaction, methane (CH₄) react with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O):

CH₄ + 2 O₂ → CO₂ + 2 H₂O

Now we calculate the number of moles of methane and carbon dioxide:

number of moles = mass / molar weight

number of moles of methane = 10 / 16.04 = 0.62 moles

number of moles of carbon dioxide = 27 / 44.01 = 0.61 moles

From the chemical reaction we see that 1 mole of methane produces 1 moles of carbon dioxide so 0.6 moles of methane produces 0.6 mole of carbon dioxide. This reaction obeys the law of conservation of mass because the mass of reactants is equal to the mass of products.

How will the properties of a biological membrane change if the fatty acid tails of the phospholipids are converted from saturate
kumpel [21]
Some of the properties that will change as the biological membrane composed primarily of phospholipids change from the saturated to unsaturated fatty acid tails of the phospholipid would include, permeability of the membrane, this will cause the membrane to be more fluid and not remain as controlling of the materials. The membrane will ultimately become poor in regulating ions and other materials from coming into the cell, as the phospholipids are not tightly packed due to them being unsaturated and having carbon double bonds within them. This can also affect the overall shape of the plasma membrane as well, causing it to be not as structured, and more fluid,
