Answer: 2.4 M
Explanation:
According to the neutralization law,
where,
= molarity of 
solution = 3.5 M
= volume of 
solution = 34.3 ml
= molarity of 
solution = ?
= volume of solution = 50 ml
= valency of = 1
= valency of = 1
Therefore, the concentration of NaOH solution is 2.4 M.
Answer:
Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire). Most of the metals are solids at room temperature, with a characteristic silvery shine (except for mercury, which is a liquid). Nonmetals are (usually) poor conductors of heat and electricity, and are not malleable or ductile; many of the elemental nonmetals are gases at room temperature, while others are liquids and others are solids.
