Acid + alkali > salt + water
the acid and alkali neutralise each other
I think should be d. Please give me brainlest let me know if its correct or not okay thanks bye
Answer:
A) C₇H₆O₂
B) C₁₄H₁₂O₄
Explanation:
To determine the empirical and molecular formula of the compound, we need to follow a series of steps.
Step 1: Divide each percentage by the atomic mass of the element
C: 43.74/12.01 = 3.64
H: 3.14/1.01 = 3.11
O: 16.61/16.00 = 1.04
Step 2: Divide all the numbers by the smallest one, i.e. 1.04
C: 3.64/1.04 = 3.5
H: 3.11/1.04 = 3
O: 1.04/1.04 = 1
Step 3: Multiply all the numbers by 2, so that all of them are integers
C: 3.5 × 2 = 7
H: 3 × 2 = 6
O: 1 × 2 = 2
The empirical formula of the compound is C₇H₆O₂.
Step 4: Determine the molar mass of the empirical formula
M(C₇H₆O₂) = 7 × M(C) + 6 × M(H) + 2 × M(O)
M(C₇H₆O₂) = 7 × 12.01 g/mol + 6 × 1.01 g/mol + 2 × 16.00 g/mol = 122.13
Step 5: Calculate "n"
We will use the following expression
n = M(compound) / M(empirical formula)
n = (244.26 g/mol) / (122.13 g/mol) = 2
Step 6: Determine the molecular formula of the compound
We determine the molecular formula by multiplying the empirical formula by "n".
C₇H₆O₂ × 2 = C₁₄H₁₂O₄
Nonferrous alloys do not contain iron as the name suggests. Ferrous is the latin word for iron. These alloys use precious metals such as gold, silver, platinum and other metals like copper, aluminum, lead, zinc and even alloys like brass. Answer is D.
