Answer:
They contain of atoms
Explanation:
That's because atomic weights or masses of each atom of each element are proportional to each other, the same number of atoms of each element will give masses that are also proportional to each other. If you start with 20 oxygen atoms, you will need 40 hydrogen atoms to make the water and you will get 20 molecules of water.
Answer : The concentration after 17.0 minutes will be,
Explanation :
The expression for first order reaction is:
where,
= concentration at time 't' (final) = ?
= concentration at time '0' (initial) = 0.100 M
k = rate constant =
t = time = 17.0 min = 1020 s (1 min = 60 s)
Now put all the given values in the above expression, we get:
Thus, the concentration after 17.0 minutes will be,
True
Explanation:
It is correct to say that the biosphere includes all of the fish that are in the ocean. Even though the ocean is part of the hydrosphere.
The biosphere includes all life form on earth wherever they may dwell from deep abyss to the high atmosphere.
The different spheres on earth are interacting with one another and they depend on each other.
Just like the earth systems, the spheres of the earth relates with each other. Even the ocean is contained in the geosphere.
