Explanation:
Answer:
No reaction.
Explanation:
An Arrhenius base (like NaOH) increases the concentration of hydroxide ions present in the solution.
If you add Rb to an aqueous solution of NaOH, you will get an explosion.
However, the Rb does not react with the OH^-. Instead, it reacts rapidly with the water.
2Rb + 2H2O → 2RbOH + H2
So much heat is generated that the hydrogen explodes:
2H2 + O2 → 2H2O
Answer:
For metals it takes a lot less energy to loose 2 electrons then to gain 6. For nonmetals it is easier to gain 2 electrons then to loose 6.

0.0013% = 0.0013 g/100 ml water, or 1.3 mg/100 ml water
so for 145 mg, you need 145×100/1.3 = 11154 ml water or 11.154 L of water. Lead is a toxic metal that affects the central nervous system.
Extensively talking, the frightened gadget is organized into essential parts, the central nervous system(CNS) and the peripheral nervous system (PNS). The CNS is the processing center of the frame and includes the mind and the spinal cord. Both of these are protected through 3 layers of membranes referred to as meninges.
The principal anxious gadget is the frame's processing center. The brain controls most of the capabilities of the frame, inclusive of cognizance, movement, thinking, speech, and the five senses of seeing, listening to, feeling, tasting and smelling. The spinal twine is an extension of the mind.
The brain is what controls all the frame's features. The spinal twine runs from the brain down via the again. It carries threadlike nerves that department out to each organ and frame part. This network of nerves relays messages from side to side from the mind to distinctive parts of the body.
