Answer:
well idk but i will take the points
Explanation:
The equation that shows the formation of chromium (ii) ion from neutral chromium atom is as follow
Cr ---> cr^2+ + 2e-
Cr^2+ is the chromium ion with oxidation state of two which is one of the common ion of chromium. Other common ion of chromium include chromium of oxidation state 6 and 3

Which statement best explains if the graph correctly represents the proportional relationship y = 0.5x? (4 points)
<span>Yes, the points shown on the line would be part of y = 0.5xYes, all proportions can be shown on a graph of this lineNo, the points shown would not be part of y = 0.5xNo, proportions cannot be represented on a graph</span>
Answer: 0.0738 M
Explanation:
1) Chemical equation:
<span>HNO₃ + LiOH → LiNO₃ + H₂O
</span>
2) Mole ratios:
1 mol HNO₃ neutralizes 1 mol LiOH
3) Number of moles of H⁺ from HNO₃:
M = n / V ⇒ n = M × V = 0.050 liter × M
4) Number of moles of OH⁻ from LiOH
M = n / V ⇒ n = M × V = 0.03690 liter × 0,100 M
5) Equivalence point:
number of moles of H⁺ = number of moles of OH⁻
⇒ 0.0500 × M = 0.03690 × 0.100
⇒ M = 0.03690 × 0.100 / 0.0500 = 0.0738 M

Answer:
A. ![K=\frac{[N_2O]^2}{[N_2]^2[O_2]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BN_2O%5D%5E2%7D%7B%5BN_2%5D%5E2%5BO_2%5D%7D)
Explanation:
Hello there!
In this case, for us to figure out the appropriate equilibrium expression, it will be firstly necessary for us to recall the law of conservation of mass which states that the equilibrium constant of an equilibrium chemical reaction is written by dividing the products and reactants and including the stoichiometric coefficients as exponents. In such a way, for the given reaction, we will have:
![K=\frac{[N_2O]^2}{[N_2]^2[O_2]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BN_2O%5D%5E2%7D%7B%5BN_2%5D%5E2%5BO_2%5D%7D)
As N2O is the product whereas N2 and O2 are reactants; thus, the equilibrium expression will be A.
Regards!
