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.

Answer:

  • <u><em>máquina simple: palanca</em></u>

Explanation:

En vista de que  la pregunta está realizada en español, la respuesta la doy en el mismo lenguage.

La<em> palanca</em> es una máquina simple que consiste en una barra rígida que puede girar alrededor the un punto the pivote.

La forma en que functiona una palanca es que se aplica la ferza en el extremo de la barra que está más alejado del pivote. Este extremo puede desplazarse una larga distancia o arco, con una fuerza pequeña, haciendo que los puntos que están al otro lado del pivote, a una menor distancia de este, se desplacen una distancia o arco menor pero con más fuerza que la aplicada.

Mr. Ragusa asks Hassan to make silver crystals from the following reaction.
SVEN [57.7K]

Answer:

Percentage yield = 61.7%

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated:

2AgNO₃ + Cu —> Cu(NO₃)₂ + 2Ag

Next, we shall determine the mass of AgNO₃ that reacted and the mass of Ag produced from the balanced equation. This is illustrated below:

Molar mass of AgNO₃ = 108 + 14 + (16×3)

= 108 + 14 + 48

= 170 g/mol

Mass of AgNO₃ from the balanced equation = 2 × 170 = 340 g

Molar mass of Ag = 108 g/mol

Mass of Ag from the balanced equation = 2 × 108 = 216 g

SUMMARY:

From the balanced equation above,

340 g of AgNO₃ reacted to produce 216 g of Ag.

Next, we shall determine the theoretical yield of Ag. This can be obtained as follow:

From the balanced equation above,

340 g of AgNO₃ reacted to produce 216 g of Ag.

Therefore, 51 g of AgNO₃ will react to produce = (51 × 216)/340 = 32.4 g of Ag.

Thus, the theoretical yield of Ag is 32.4 g.

Finally, we shall determine the percentage yield of Ag. This can be obtained as follow:

Actual yield = 20 g

Theoretical yield = 32.4 g

Percentage yield =?

Percentage yield = Actual yield /Theoretical yield × 100

Percentage yield = 20 / 32.4 × 100

Percentage yield = 61.7%
