Psychochemical may persist for hours or days after exposure.

<h3>Psychochemical </h3>

Chemical substances that have brief, reversible effects on the body or mind are known as psychochemical agents, often known as incapacitating substances. Psychochemical agents have a longer-lasting effect than riot-control chemicals, which only have a few-minute duration. Central nervous system (CNS) stimulants and depressants both fall within the category of psychochemical substances.

Drugs that depress the central nervous system (CNS) prevent the CNS from functioning and prevent information from traveling across neuron synapses. 3-Quinuchdedinyl Benzilate is an illustration of this group of chemicals, and it has an impact on memory, problem-solving, focus, and instruction-listening abilities. Instead of affecting one's ability to think, cannabinoids and phenothiazines cause sleepiness and a lack of motivation. Although 10,000 times more strong than morphine, fenyls are opiates that have a similar effect.

o-na [289]

Answer:

C the number and placement of the electrons

245 g water sample initially at at 32 oC absorbs 17 kcal of heat. What is the final temperature of water?
steposvetlana [31]

Answer:62.66°C or 235.66K

Explanation:Q=McpT, the energy was given in calories so you first convert to Joules by multiplying the value in calories by 4.184J.

17*4.184=71.128kJ.

71.128kJ=mcpT

71.128kJ=245*4.187*(T-Tm)

Tm is the final temperature of the mixture. The T is the temperature given which should be converted to Kelvin by adding 273...T=32+273=305K.

71128J=245*4.187*(305-Tm)

71128=312873.575-1025.815Tm

1025.815Tm=312873.575-71128

1025.815Tm=241745.58

Tm=241745.58/1025.815

Tm=235.66K
