Creating Wetlands. When beavers make a dam, they slow the flow of water in the stream and, subsequently, a pond or area of wetland is formed. Roughly 85 percent off all native North American fauna rely on wetlands, so they're extremely important to the ecosystem.

Using the Hoffman apparatus for electrolysis, a chemist decomposes 2.3 moles of water into its gaseous elements. How many grams

solong [7]

Answer:

2.318032g

Explanation:

-The electrolysis equation of water is written as below:

$2H_2O_{(l)}->2H_2_{(g)}+O_2_{(g)}$

-The mole ratio of Water to the hydrogen formed is 1:1, therefore 2.3 moles of hydrogen gas is produced.

-Hydrogen's molar mass is 1.00784 grams:

$Mass=moles\times molar \ mass\\\\\=2.3\times 1.00784\\\\=2.318032\ g$

Hence, 2.318032 grams of hydrogen is produced.

Answer:

Every object that travel at the speed of light gains infinite mass. Is a law in physics that as it gains speed, it is gaining mass. Then, not is necesary that a meteorite hit the Earth at the speed of light, because just an atom traveling a this velocities could destroy our planet.

Explanation:

The speed of light is really fast so that will mostly happen
