Answer:
<em>Liquids and gases are called fluids because they can be made to flow, or move.</em>
<em> In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container.</em><em> </em><em>So</em><em> </em><em>that</em><em> </em><em>they're</em><em> </em><em>called</em><em> </em><em>fluids</em><em>.</em>
Mercury is a homogenous mixture of two or more pure substances
Answer:
M
Explanation:
Equation for the reaction is as follows:
+ 
⇄ 
By Applying the ICE Table; we have
+ ⇄
Initial x 0.0025 M 0.0010 M
Change 0 0 0
Equilibrium x 0.0025 M 0.0010 M
![K_c =\frac{[CO_2]^2}{[CO]^2[O_2]}](https://tex.z-dn.net/?f=K_c%20%3D%5Cfrac%7B%5BCO_2%5D%5E2%7D%7B%5BCO%5D%5E2%5BO_2%5D%7D)
Given that 
; Then:
M
∴ The equilibrium concentration of CO = M
Answer:
all these are physical properties except release of heat so it's probably heat energy given off
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles. Calculations are as follows:
</span>2.50 mol FeWO4 ( 1 mol Fe / 1 mol FeWO4 ) ( <span>6.022 x 10^23 atoms Fe / 1 mol Fe )</span>= 1.51 x 10^24 atoms Fe
