Answer:
The smell from the cake leaves the room at high velocities because of diffusion.
Kinetic theory:
The kinetic theory applies to gases and describes their random movement and collisions in the whole volume that they are allowed to fill. This movement depends on factors like temperature and pressure.
Coffee and bacon particles will exist in the air in gaseous form. They will be colliding with each other, with all the other air particles and with the room walls to eventually disperse evenly in the whole room. They will be detected when coming into contact with olfactory receptors in the nose. They will reach the nose at the same temperature and there are equal amounts of particles of each.
Because nothing appeared he concluded that <span>that living things could NOT just appear or come from nonliving things like water and air</span>
It becomes:
6CO2 + 6H2O -> C6H12O6 + 6O2
4 m/s^2
I hope this helps!
Answer:
85.8 g
Explanation:
The molar mass of BaCl₂ is 208.233 g/mol, so 210.1 g is about ...
210.1/208.233 ≈ 1.009 mol
The molar mass of K is about 39.089 g/mol, so 45 g is about ...
45/39.089 ≈ 1.1509 mol
The balanced equation seems to be ...
BaCl₂ + 2K ↔ 2KCl + Ba
This reaction requires 2 moles of potassium for each mole of barium chloride, so the available potassium limits the reaction. The result is as many moles of potassium chloride as there are moles of potassium.
The 1.1509 moles of KCl, at 74.551 g/mol will have a mass of about 85.8 g.
The reaction produces 85.8 g of KCl.
