Answer:
the correct answer B. carboxylic acid
Explanation:
carboxylic acid, any of a class of organic compounds in which a carbon (C) atom is bonded to an oxygen (O) atom by a double bond and to a hydroxyl group (―OH) by a single bond. A fourth bond links the carbon atom to a hydrogen (H) atom or to some other univalent combining group.
Answer:
Explanation:
In alpha decay alpha ray comes out . Apha ray is nothing but nucleus of helium atom whose atomic no is 2 and atomic weight is 4 . Hence in alpha decay , atomic weight reduces by 4 and atomic no reduces by 2. For gamma emission , there is no change in atomic number and atomic mass.
⁹²₂₇AL ⇒ ⁸⁸₂₅X + ⁴₂He + γ
X is Manganese .
Molarity = moles / Volume in liters
M = 0.45 / 3.0
M = 0.15 mol/L
