The reaction between the lemonade powder and water occurs on the surface of the powder particles. By moving through the water, the lemonade powder particles comes into contact with water molecules.<span> Stirring induces the lemonade powder to move faster through the water. It actually increases the kinetic energy of the lemonade powder and causes them to move rapidly. The bigger the kinetic energy is, more particles can come into contact with more water molecules and, thus, the lemonade powder dissolves faster.</span>

Answer: Membrane Protiens
Explanation:
In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.
Answer:
1.2 x 10²³atoms
Explanation:
Given parameters:
Mass of CO(NH₂) = 12g
Unknown:
Number of Nitrogen atoms = ?
Solution:
Given compound;
CO(NH₂);
In;
1 mole of CO(NH₂), we have 1 mole of N
let us find the number of moles of CO(NH₂);
Number of moles =
Number of moles = = 0.2moles
Since
1 mole of CO(NH₂), we have 1 mole of N
0.2 mole of CO(NH₂) will have 0.2mole of N
1 mole of a substance contains 6.02 x 10²³ atoms
0.2 mole of N will contain 0.2 x 6.02 x 10²³ atoms = 1.2 x 10²³atoms
