Answer:
Chemical bonds are the electrical forces of attraction that hold atoms or ions together to form molecules. Different types of chemical bonds and their varying intensity are directly responsible for some of the physical properties of minerals such as hardness, melting and boiling points, solubility, and conductivity.
Explanation:
Answer:
C
Explanation:
Well, we can see from the equation that hydrogen gas and ethane are in a 2:1 ratio based on their mole coefficients.
You need 2 mol H2 to make 1 mol C2H6. So that means you need 2*13.78 mol H2 to make 13.78 mol C2H6!
2*13.78 = 27.56 mol
C is correct.
Answer: Lithium (Li) 16.373%
Chlorine (Cl) 83.627%
Explanation:
The fridge part can, just not the freezer, I think.
C2H2O4 C2HO4- + H+
0.175 - x x x + y
C2HO4- c2o42– + H+
x - y y x + y
K2 = (y) (x +y) / (x-y)
As, y << x
So, K2 = (y) (x) / (x)
K2 = y =6.1 × 10^–5
Hence, concentration of (c2o42–) 6.1 × 10^–5 M
