Answer:

They are portable resources that convert chemical energy to electrical energy.

Explanation:

Batteries are sets of batteries connected in series, that is, they are electrochemical devices in which oxidation reduction reactions (chemical energy) occur, producing an electric current (electrical energy). They can also be called secondary batteries, secondary batteries or accumulators.

Fuel cells, in turn, also transform chemical energy into electrical energy, and their operation produces low environmental impact: no vibrations, no noise, no combustion, no emission of particulates and, depending on the technology, no emission of greenhouse gases. In addition, in the current stage of development, without emission of acid gases and with low pollution.

With that, we can say that batteries and fuel cells are practical because they are portable resources that convert chemical energy into electrical energy.

polet [3.4K]

Answer:

both

Explanation:

Carbon in the air around the living thing is moving in and out of its lungs. The movement is occurring at the same time. This is one of the most important gaseous exchange important to life.

The goats takes in oxygen gas from the surrounding and releases carbon dioxide in the process.
But, air is actually drawn in by the goat which is a mixture of several gases.
Air contains carbon dioxide which is a rich source of carbon
With the carbon dioxide from respiratory processes, the goat ejects and breathes out this waste carbon matter.
Therefore, the gaseous exchange in a goat involves the movement of carbon in and out of the air.

Answer: $Zn(s)+CuSO_4(aq)\rightarrow ZnSO_4+Cu$

Explanation:-

Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

As zinc is more reactive than copper, it could easily displace copper from its aqueous solution and thus leads to formation of zinc (II) sulfate and pure copper.

The chemical reaction can be represented as :

$Zn(s)+CuSO_4(aq)\rightarrow ZnSO_4+Cu$

The phases are represented as (s) for solid sate, (l) for liquid state, (g) for gaseous state and (aq) for aqueous state.
