The kinetic energy of a substance's particles in the liquid phase compare to their kinetic energy in the gas phase in a way that the particles have less kinetic energy in the liquid phase than they do in the gas phase.
Answer:
4 biological membranes.
Explanation:
So in total, your water molecule has to go through your cell membrane, reach the outer membrane of your chloroplast and then through the inner membrane, and then lastly, it has to go through your thylakoid membrane to reach its final destination of the illumine. So in total 4 biological membranes.
False, Molecules are made of atoms and atoms are made of quarks.
Answer: 50. 4g
Explanation:
First calculate number of moles of aluminium in 38.8g
Moles = 38.8g/ 26.982mol/g
= 1.44mol
By looking at the balance equation you can see that 4 moles of aluminium produce 2 moles of aluminium oxide.
4 = 2
1.4 = x
Find the value of x
x= (1.4×2)/4= 0.72 mol
0.72 moles of aluminium oxide are produced from 38.8g of aluminium
Now find the mass of aluminium produced.
Mass = moles × molar mass
= 0.72mol × 69.93 mol/g
= 50.4g
0.137 L of the stock solution
M1V1 = M2V2
M1 = 3.25 M
V1 = This is what we’re solving for.
M2 = 1.25 M
V2 = 0.355 L
Solve for V1 —> V1 = M2V2/M1
V1 = (1.25 M)(0.355 L) / (3.25 M) = 0.137 L
