Melted rock can ooze out from below the earth's surface through a crack called a fault.
Additional reactants would break equilibrium
Answer:
2/6
Explanation:
In a balanced chemical equation as:
aA + bB → cC + dD
Where coefficients of reaction relates the number of moles of substances that are involved in the reaction. In the reaction:
Mg₃N₂(s) + 6H₂O(l) → 3Mg(OH)₂(s) + 2NH₃(g)
Per mole of Mg₃N₂(s) and per 6 moles of H₂O you will produce 3 moles of Mg(OH)₂(s) and 2 moles of NH₃(g).
To convert moles of H₂O to moles of NH₃ you can use:
X moles of H₂O ₓ (2 moles NH₃ / 6 moles of H₂O)
That means conversion factor to convert the number of moles of water to number of moles of ammonia is <em>2/6</em>.
<em>-It is important to say that obtention of conversion factor requires, in the first, the balanced chemical equation-</em>

Answer:
pH = 6.80. The aqueous solution is slightly acid
If pH is 7.00 at 37°C, solution is neutral
Explanation:
2H₂O ⇄ H₃O⁺ + OH⁻ Kw = 2.4×10⁻¹⁴
To determine the pH of a solution, we must consider the [H₃O⁺]
[H₃O⁺] . [OH⁻] = 2.4×10⁻¹⁴
[H₃O⁺] = [OH⁻] → √2.4×10⁻¹⁴ = [H₃O⁺]
1.55×10⁻⁷ = [H₃O⁺]
pH = - log 1.55×10⁻⁷ = 6.80
pH = 7 → neutral
pH < 7 → acid
pH > 7→ basic
Answer:
A. 25Mn45^+
B. 45Rh69^+2
C. 53I142^-
D. 97Bk^243
Explanation:
Generally Atomic mass (A)= no of protons (p) + no of neutrons (n)
No of Neutrons (n)=A-p
No of protons = Atomic number
Symbol for nulclide: zX^A
Z is Atomic number, A is Atomic mass
And X is symbol of element
