Answer:
True
Explanation:
The volume of water displaced by an object completely submerged is its actual volume. It implies that in the container the object create a space of size for itself which is the volume of the object. This approach is used in calculating the density of many irregular solids from their measured masses.
Explanation:
Ozone, or 03,has two major resonance structures that contribute equally to the overall hybird structure of the molecule. The two structures are equivalent from the stability standpoint, each having a positive and a negative formal charge placed on two of the oxygen atoms.
Answer:
Lithium will lose about 2 electrons
Making it a cation
Answer:
They decrease, because of the stronger effective nuclear charge.
Explanation:
- Atomic radii decreases from left to right across a period.
- This is due to the increase in the no. of protons and electrons through the period.
- One proton has a greater effect than one electron.
- So, electrons are attracted towards the nucleus and resulting in a smaller atomic radii.
<em>Thus, the right choice is: They decrease, because of the stronger effective nuclear charge.</em>
