Answer:
278 balloons can be aired.
Explanation:
We apply the Ideal Gases Law to determine the total available volume for each baloon of 0.75L. So we need to divide the volume we obtain by the volume of each baloon.
We determine the moles of CO₂
375 g. 1 mol / 44g = 8.52 moles
V = (n . R . T) / P → (8.52 mol . 0.082 . 298K) / 1 atm = 208.3 L
That's the total volume from the tank, so we can inflate (208.3 / 0.75) = at least 278 balloons
Pollution because it’s one of the reasons for global warming, and global warming causes habitat destruction causing many organisms to become extinct
Answer:
Sulfur (Option-C) <span>exhibits chemical behavior similar to that of oxygen.
Explanation:
Sulfur has same chemical properties as that of Oxygen because both of them belongs to same group in the periodic table. Also, the similarity of chemical behaviour among the group members is due to same number of electrons in their valence shells.
For examole, the electronic configuration of Oxygen is,
1s</span>², 2s², 2p⁴
There are six valence electrons in the valence shell (i.e. 2) of Oxygen.
Now for Sulfur,
1s², 2s², 2p⁶, 3s², 3p⁴
There are six valence electrons in the valence shell (i.e. 3) of Sulfur.
Therefore, both elements tends to gain 2 electrons in a reaction and form O⁻² and S⁻² respectively.
