Answer:

A) Na

Explanation:

We analyze the change of electrons in the equation.

So:

S (0) --> S (-2)

The oxidizing agent is the one that gains electrons. Sulfur goes from 0 to -2 then it is gaining electrons.

Na (0) --> Na (+1)

The reducing agent is the one that loses electrons. Sodium goes from 0 to +1 which means that it loses electrons.

Therefore the reducing agent is Na.

When a saturated solution of NH4Br dissolved in 100 grams of water is cooled from 60°C to 30°C, how much NH4Br will precipitate?

stepladder [879]

Answer:

$m_{precipitated}=24.8g$

Explanation:

Hello,

In this case, since at 60 °C, 108 grams of ammonium bromide are completely dissolved in 100 grams of water for a saturated solution, once it is cooled to 30 °C, wherein only 83.2 grams are completely dissolved in 100 grams of water, the following mass will precipitate:

$m_{precipitated}=108g-83.2g\\\\m_{precipitated}=24.8g$

Best regards.

Answer:

cools as it rises, then sinks back down

Explanation:

The movement of air is a convection current. Convection currents occur when warm air rises, cools down, and sinks due to gained density, replacing the warm air closer to the ground, creating a cycle.
