Questions:

The questions or computes to do are:

<span>a- a massa, em kg, de cada placa de alumínio;

b- a quantidade mínima de viagens necessárias para que apenas um veículo de transporte entregue o material solicitado ao cliente.

Dado: densidade do alumínio = 2,7 g/cm3

Answer:

a) mass in kg of every aluminum plate

Dimensions of every aluminum plate: </span>
<span>2 M X 50 Cm X 2cm

Volume: 200 cm * 50 cm * 2 cm = 20,000 cm^3

Mass:

density = mass / volume => mass = density * volume = 2.7 g/cm^3 * 20,000 cm^3 = 54,000 g = 54 kg.

Answer: the mass of everyplate of aluminum is 54 kg.

b) number of travels required for one truck deliver all the material:

number of travels = amount requested / amount that a truck can deliver in one travel.

amount requested: 100 plates

mass of 100 plates = 100 plates * 54 kg / plate = 5,400 kg

limit of transport per travel: 3 tons = 3,000 kg

number of travels = 5,400 kg / 3,000 kg/travel = 1.8 travels => 2 travels.

Answer: at least 2 travels.

Estructura correcta de los siguientes compuestos e indique si el nombre está escrito de forma correcta; 1,4-ciclohexadieno
Makovka662 [10]

Answer:

En la imagen adjunta.

Explanation:

¡Hola!

En este caso, dados los lineamientos IUPAC que tenemos en cuenta para dibujar la estructura de hidrocarburos cíclicos, para el 1,4-ciclohexadieno, es posible determinar que esta estructura viene dada por hexágono que representa el ciclohexano y dos dobles enlaces en los carbonos 1 y 4 al ser un dieno. Por lo anterior, en la imagen adjunta, puede encontrar la estructura requerida.

¡Saludos!

BRAINLIEST IF RIGHT WITH EXPLANATION
lutik1710 [3]

Answer:

15.37 atm

Explanation:

According to Dalton's law of partial pressure, the total pressure of a mixture of gases in the tank is a sum of the individual pressures of all the gases. Hence;

PT = P1 + P2 + P3 -----------

So;

Ptotal = Phelium + Poxygen

Poxygen = 4.63 atm

Ptotal = 20.0 atm

Phelium = 20.0 atm - 4.63 atm

Phelium = 15.37 atm
