Look at the periodic table to find the charge on atoms.
Magnesium is +2 and Nitrogen is -3. Since there are two nitrogen charge 2*-3 = -6 there needs to be 3 Mg then (3*2+ = 6+) to pair with the two nitrogen.
3 Mg(+2) + 2 N(-3) = Mg3N2
Answer:
Oxygen and Carbon dioxide
Explanation:
Oxygen is required for respiration whereby energy is released from natural occurring nutrients accompanied by the release of water and carbon dioxide. carbon dioxideis also required by plants to photosynthesise.
Oxygen and carbon dioxide in the troposphere supports life as by enabling respiration in organisms and photosynthesise in plants can. Without oxygen in an environment, only life forms that live by anaerobic respiration will thrive. This affects a regions carrying capacity
Answer:
The <u>equilibrium constant</u> is:
![k_c=0.0030M^{-2}](https://tex.z-dn.net/?f=k_c%3D0.0030M%5E%7B-2%7D)
Explanation:
The correct equation is:
Thus, with the equilibrium concentrations you can calculate the equilibrium constant, Kc.
The equation for the equilibrium constant is:
![k_c=\dfrac{[NH_3]^2}{[N_2]\cdot [H_2]^3}](https://tex.z-dn.net/?f=k_c%3D%5Cdfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5Ccdot%20%5BH_2%5D%5E3%7D)
Substituting:
![k_c=\dfrac{(0.105M)^2}{(1.1M)\cdot (1.50M)^3}](https://tex.z-dn.net/?f=k_c%3D%5Cdfrac%7B%280.105M%29%5E2%7D%7B%281.1M%29%5Ccdot%20%281.50M%29%5E3%7D)
![k_c=0.0030M^{-2}](https://tex.z-dn.net/?f=k_c%3D0.0030M%5E%7B-2%7D)
This thermochemical equation needs to be balanced. Hence, option B is correct.
<h3>What is a balanced chemical equation?</h3>
A balanced equation contains the same number of each type of atom on both the left and right sides of the reaction arrow.
The balanced thermochemical equation is:
→ ![2HCl (l) + 2Na (s) + 2O_3 (g)](https://tex.z-dn.net/?f=2HCl%20%28l%29%20%2B%202Na%20%28s%29%20%2B%202O_3%20%28g%29)
Hence, option B is correct.
