Answer:
(in chemistry) a type of acid containing a very light gas (hydrogen) and a greenish-yellow gas with a strong smell (chlorine)
Explanation:
It's used industrially to process steel, the material of choice for suspension bridges and cars and trucks. Hydrochloric acid is also used in the production of batteries, photoflash bulbs and fireworks. It's even used to process sugar and make gelatin.
The answer would be B, 7 valence electrons. <span>F is located
in the 1s-orbital and the second energy level, which in fluorine's case
is the outermost energy level, meaning it has <span>7 electrons</span></span>
Answer:
Components present of sodium bicarbonate
Sodium bicarbonate is formed by mixing carbon, sodium, hydrogen and oxygen molecules. This mixture, also known as baking soda, is actually a type of salt.
Explanation:
Answer:
1.2 M
Explanation:
Let's consider the following reversible reaction.
CuS(s) + O₂(g) ⇌ Cu(s) + SO₂(g)
To find the equilibrium concentration of O₂ we will use an ICE Chart. We will only consider gases and aqueous species since the activity of solids and liquids is 1.
CuS(s) + O₂(g) ⇌ Cu(s) + SO₂(g)
I 2.9 0
C -x +x
E 2.9-x x
The equilibrium constant (Kc) is:
![Kc=1.5=\frac{[SO_{2}]}{[O_{2}]} =\frac{x}{2.9-x} \\x=1.7](https://tex.z-dn.net/?f=Kc%3D1.5%3D%5Cfrac%7B%5BSO_%7B2%7D%5D%7D%7B%5BO_%7B2%7D%5D%7D%20%3D%5Cfrac%7Bx%7D%7B2.9-x%7D%20%5C%5Cx%3D1.7)
The concentration of O₂ at equilibrium is:
[O₂] = 2.9 -x = 2.9 - 1.7 = 1.2 M
