Environmental Chemistry studies the health hazards associated with lead, which  is dangerous to humans.

Environmental Chemistry studies chemicals present in air, water and soil and their  impact on humans and their environment.

Now, it was discovered that even low doses of lead particles in the paint when inhaled or ingested caused damaging effect to the body  such as Impaired balance, seizures, ataxia and even death.

With the role of Environmental chemists in thier research and findings, the world has been informed on the negative effect on the expose of lead and other heavy metals like it  to man and his environment.

lead is a toxic metal that affects the central nervous system. a pbpb-contaminated water sample contains 0.0013 %pb%pb by mass.
Rus_ich [418]

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.

A 15.0 L rigid container was charged with 0.5 atm of Krypton gas and 1.5 atm of chlorine gas at 350 C. The krypton and chlorine
Angelina_Jolie [31]

The mass of krypton tetrachloride that can be produced assuming 100% yield is mathematically given as

molar mass=33.29g

<h3>What mass of krypton tetrachloride can be produced assuming 100% yield?</h3>

Generally, the equation for ideal gas is mathematically given as

PV=nRT

Therefore

n=(0.50)(15.)/0.082*623

n=0.147mol

Hence for clorine

n=0.441mol

Given the reaction

Kr+2cl2---->KrCL4

Hence

molar mass=225.60*0.147

molar mass=33.29g
