Answer:
200x
Explanation:
<em>The total magnification of a microscope depends on the power of the eyepiece and that of the objective lens. It is obtained by multiplying the two factors together. </em>
The total magnification of a microscope can be mathematically expressed as:
Total Magnification = <em>ocular/eyepiece magnification x objective magnification</em>
In the illustration, eyepiece magnification = 10 and objective magnification = 20. Hence,
Total Magnification = 10 x 20 = 200x
Answer:
(limonene) particles go from liquid to vapour
diffusion
random movement of particles / particles move anywhere / particles move in all directions
spreading out of particles / intermingling of particles / mixing of particles / particles collide / particles bounce off each
other / particles go all over
(bulk) movement of particles from higher to lower concentration / movement of particles down concentration gradient
Osmium atomic number is 76
This problem is providing the mass, specific heat and melting point of aluminum and the amount of heat it receives in a heating process so it asks for the change in its temperature, which results in 64.36 °C.
<h3>Calorimetry</h3>
In chemistry, one can perform calorimetry calculations with the widely-known heat equation relating mass, specific heat, temperature and heat:
Thus, when having 1250.0 g of aluminum at -35.0 °C and supplying 72.41 kJ (72,410 J) of heat, we will be able to solve for the change in temperature by solving for it in the previous formula:
Which is not as high as for it to provoke a melting change, with the correct significant figures as 0.90 do not contribute to this for being a theoretical number.

Hey there!
Molar mass of O3 = 47.9982 g/mol
therefore:
1 mole O₃ --------------------- 47.9982 g
moles O₃ ---------------------- 24 g
moles O₃ = 24 x 1 / 47.9982
moles O₃ = 24 / 47.9982
moles O₃ = 0.500 moles
Hope this helps!
