When they ask you for the solution they are usually asking for x. So solve for X.
X=-12 so you only have one solution. so the answer is B
The empirical formula CH₂O has a mass [(12 × 1) + (1 × 2) + (16 × 1)] = 30 g/mol
If the empirical formula is 30 g/mol,
and the molecular formula is 60 g/mol
Then the multiple is = 60 g/mol ÷ 30 g/mol
= 2
Therefor the molecular formula is 2(CH₂O) = C₂H₄O₂ (OPTION 2)
Answer : The equilibrium constant for this reaction is, 
Explanation :
The given main chemical reaction is:
; 
The intermediate reactions are:
(1) 
; 
(2) 
; 
We are reversing reaction 1 and multiplying reaction 2 by 2 and then adding both reaction, we get:
(1) 
; 
(2) 
; 
Thus, the equilibrium constant for this reaction will be:
Thus, the equilibrium constant for this reaction is,

Answer:
Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O
Explanation:
Reactants;
Calcium hydroxide = Ca(OH)₂
Hydrogen chloride = HCl
Products;
Calcium chloride = CaCl₂
Water = H₂O
The reaction equation:
Ca(OH)₂ + 2HCl → CaCl₂ + 2H₂O
The reaction is a neutralization reaction where acids reacts with bases to produce salt and water only.
