A presença da metanfetamina — uma droga alucinógena ilícita - em fluidos biológicos pode ser determinada por espectrometria de massa. O espectro de massa da metanfetamina
apresenta um pico de 58 u bastante característico. A partir da fórmula estrutural da
metanfetamina mostrada acima e considerando que M(H) = 1 g/mol, M(C) = 12 g/mol e M(N) =
14 g/mol, julgue o item a seguir como certo ou errado, justificando a sua resposta. Existem dois
enantiômeros da metanfetamina capazes de desviar o plano da luz polarizada.

The movement of tectonic plates and in two locations is described below: location a: tectonic played push together location b: tectonic plates push apart

2ki + pb(no3)2 → 2kno3 + pbi2 determine how many moles of kno3 are created if 0.03 moles of ki are completely consumed.

(04.05 hc) analyze the given diagram of the carbon cycle below. an image of carbon cycle is shown. the sun, a cloud, two trees, one on the left and the other on the right, an animal, lake, and a factory are shown in the image. an arrow is shown from the sun towards the left tree marked a. the sun is marked b. there is an arrow from the air above the clouds, marked c, towards the left tree. an arrow from a location close to the ground marked d points towards dead organisms, which is a label under the animal. an arrow marked e points from the right tree straight up to the clouds. an arrow marked f points from the animal straight up to the clouds. an arrow marked g points from the factory towards the air above the clouds, c. there is an arrow pointing from the air to the lake labeled carbonates in water, an arrow pointing down from dead organisms to fossils and fossil fuels, and an arrow from fossils to the factory. part 1: which compound does c represent? part 2: name a process that could release this compound into the air. part 3: explain how the elements that form it are conserved during the carbon cycle. use complete sentences to explain your answer.
