Removing seed casings from grains is SEPARATING. a soda bubble bubbling when it is opened is MIXING. a bright copper statue turning green is MIXING. remove salt from seawater is SEPARATING. water decomposing is SEPARATING.
Diffusion : a process in which molecules intermingle as a result of their kinetic energy of random motion
The primary cause of diffusion is : 3. Random internal motion of atoms and molecules

I would expect silane because all the rest have an overall dipole movement
Answer:
<h2>10.03</h2>
Explanation:
The pH of a solution can be found by using the formula
![pH = - log [ {H}^{+} ]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B%20%7BH%7D%5E%7B%2B%7D%20%5D)
From the question we have

We have the final answer as
<h3>10.03</h3>
Hope this helps you
<u>Answer:</u> The concentration of
ions are 2.797 ppm and 0.212 ppm respectively.
<u>Explanation:</u>
To calculate the mass of solution, we use the equation:

Volume of gold = 100 L = 100000 mL (Conversion factor: 1 L = 1000 mL)
Density of gold = 1.001 g/mL
Putting values in above equation, we get:

To calculate the concentration in ppm (by mass), we use the equation:

- <u>Calculating the concentration of calcium ions:</u>
Mass of
ions = 0.280 g
Putting values in above equation, we get:

- <u>Calculating the concentration of magnesium ions:</u>
Mass of
ions = 0.0220 g
Putting values in above equation, we get:

Hence, the concentration of
ions are 2.797 ppm and 0.212 ppm respectively.
