Answer: the answer is option 3. C
Explanation:
Alkaline earth metals
group 2 (IIA)
Answer:
False
Explanation:
Electrophilic addition reactions may be under kinetic or thermodynamic control. Whether the reaction is under kinetic or thermodynamic control is easily deducible from the reaction time.
Shorter reaction time often reflect kinetic control while longer reaction reaction times favour thermodynamic control.
Hence, electrophilic addition reaction of conjugated dienes that occur at high temperature and/or long reaction times (reversible conditions) are said to be under thermodynamic and not kinetic control.
Answer:
0.43
Explanation:
divide the given mass by molar mass from the periodic table
Answer:
True
Explanation:
When an atom has lost an electron, the overall charge is going to be positive
( + ) because there is more protons than electrons rather than a normal atom where the protons equal the number of electrons which means the overall charge is 0 since the protons cancel out the electrons but in this atom the protons is greater than the electrons so the charge is positive
