The molecule that could diffuse across the plasma membrane is methane (CH4).

<h3>What is diffusion?</h3>

Diffusion is the movement of fluids or substances from regions of high concentration toward regions of lower concentration.

The plasma membrane is the semipermeable membrane that surrounds the cytoplasm of a cell. The semipermeability means that it allows some molecules through but blocks other substances.

The semipermeable plasma membrane readily allows the passage of small hydrophobic and polar molecules.

Therefore, the molecule that could diffuse across the plasma membrane is methane (CH4).

In the reaction aA + bB &gt;&gt; dD, the lowercase letters represent?
jolli1 [7]

Answer:

Coefficient

Explanation:

Chemical equation:

aA + bB    →   dD

This equation shows that reaction is balanced by coefficient q,b and d.

Reactant    coefficients              Product      Coefficient

A                    a                               D                     d

 B                    b                  

Every balanced equation follow the law of conservation of mass.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Explanation:

This law was given by french chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass. The numbers 6 with CO₂, 6 with H₂O and 6 with O₂  are coefficient which balance the equation.

When zinc and HCl are reacted, the product is hydrogen gas. You can measure the reaction rate by measuring what?
Zarrin [17]

Answer:

measuring the consumption of the products and the rate of conversion of products to reagents

Explanation:

It must be taken into account that the reaction rate also depends on the presence of a catalyst, since these advance the rate of the reaction.
