Answer:
Barium will form ions most readily because it is most metallic and ions electrons readily and form a positive ion. All these element have 2 valence electrons
Answer:
6(3) - 4 + (3)^2
Explanation:
We are given that:
f(x) = 4-x^2
g(x) = 6x
First, we will compute (g-f)(x) as follows:
(g-f)(x) = 6x - (4-x^2) = 6x - 4 + x^2
Now, we will substitute with x=3 as follows:
(g-f)(3) = 6(3) - 4 + (3)^2
Hope this helps :)
Answer:
1. Na + O2 → Na2O (Balanced)
2. 4Al + 3O2 → 2(Al2O3) (Balanced)
3. H2 + i2 → 2HI (Balanced)
4. Mg + 2H2O → Mg(OH)2+ H2 (Balanced)
5. 2Ca +O2 → 2CaO (Balanced)
True!
Explanation:
Dialysis is the separation of smaller molecules from larger molecules or of dissolved substances from colloidal particles in a solution by selective diffusion through a semipermeable membrane. The most common usage is that of blood, or kidney dialysis, but the process can be used for sea or drinking water as well.
