its the same thing as 3 x3 or 3+3 it always come´s back as 9 or 6 Because of life
Explanation:
Longitudinal waves. In a longitudinal wave the particles in the medium move parallel to the direction waves go. A good example can be the p-waves in an earthquake.
Answer:
It's D. On the surface of the solid.
Explanation:
If the reactant is a solid, the surface area of the solid will impact how fast the reaction goes. This is because the two types of molecule can only bump into each other at the liquid solid interface, i.e. on the surface of the solid. So the larger the surface area of the solid, the faster the reaction will be.
Answer:
12g KCl will be crystallized
Explanation:
To solve this problem you need to know solubility of KCl in water at 20°C is 34g per 100g of water.
That means the maximum concentration of KCl you can dissolve at 20°C in 200g of water is 34g×2 = 68g of KCl
As solution containing 80g of KCl, the extra KCl will be crystallized after cooling, that is:
80g of KCl - 68g of KCl = <em>12g KCl will be crystallized</em>
I hope it helps!
