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.

Explanation: -Nitrogen is the element that may form diatomic molecules held together by triple covalent bonds. -Nitrogen is an element that occurs as a diatomic molecule in its gaseous state. This element only exists in the diatomic form with triple bonds between the two atoms.
Explanation:
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
Answer:
Explanation: Zaitsev’s or Saytzev’s (anglicized spelling) rule is an empirical rule used to predict regioselectivity of 1,2-elimination reactions occurring via E1 mechanism or via E2 mechanism. It states that in a regioselective E1 or E2 reaction the major product is the more stable alkene, i.e., the alkene with the more highly substituted double bond.
E1 reaction always follow Zaitsev’s rule; with E2 reactions, there are exceptions (see antiperiplanar).
