If the glass was flexible, it would expand until it popped. If it was less stretchy, it would likely shatter and explode outward when the pressure inside is too high.

In what way do the oceans and the forests perform a similar function in the carbon cycle, under normal conditions?.
ikadub [295]

Both take carbon dioxide out of the atmosphere.

The ocean absorbs much of the carbon dioxide released when fossil fuels are burned. This extra carbon dioxide lowers the ocean's pH through a process called ocean acidification. Both are important elements for all life on earth. Relationship between the water cycle and the carbon cycle. The sun's energy drives both the carbon cycle and the water cycle.

Recall that sunlight water and carbon dioxide combine in green plants via photosynthesis to produce carbohydrates. The ocean also regulates the Earth's climate. They determine the weather by telling temperatures and determining rainfall, droughts, and floods. It is also the world's largest carbon sink, with an estimated 83% of the global carbon cycle circulating in seawater.

is trying to plate gold onto his silver ring. He constructs an electrolytic cell using his ring as one of the electrodes. He run
notka56 [123]

Answer:

0.013 mole.

Explanation:

From the question given above, the following data were obtained:

Time (t) = 94.6 mins

Current (I) = 224.8 mA.

Mole of electrons (e) =?

Next, we shall convert 94.6 mins to seconds. This is illustrated below:

1 min = 60 s

Therefore,

94.6 mins = 94.6 min × 60 s / 1 min

94.6 mins = 5676 s

Thus, 94.6 mins is equivalent to 5676 s.

Next, we shall convert 224.8 mA to ampere (A). This can be obtained as follow:

1 mA = 1×10¯³ A

Therefore,

224.8 mA = 224.8 mA × 1×10¯³ A / 1 mA

224.8 mA = 0.2248 A

Thus, 224.8 mA is equivalent to 0.2248 A.

Next, we shall determine the quantity of electricity flowing in circuit. This can be obtained as follow:

Time (t) = 5676 s

Current (I) = 0.2248 A

Quantity of electricity (Q) =?

Q = it

Q = 0.2248 × 5676

Q = 1275.96 C

Finally, we shall determine the mole of electron by converting the quantity of electricity (i.e 1275.96 C) to number of electrons. This can be obtained as follow:

96500 C = 1 e

Therefore,

1275.96 C = 1275.96 C × 1 e / 96500 C

96500 C = 0.013 e

Thus, the mole of electron trasfered in the process is 0.013 mole.
