Answer:
K
Explanation:
The picture that demonstrates a state of matter without a fixed shape or fixed volume is picture K.
Gases are one of the three states of matter without a fixed shape and volume. They simply take up the shape of their containers and are free to move all about.
- Liquids and solids are known to have fixed shape and volume.
- Liquids are know for their ability to flow. Figure L
- Solids are rigid bodies. It is the figure J
1. an alpha particle
gamma rays are formally massless, positrons and electrons (beta particles) have negligible mass, but alpha particles have about 4 amu of mass
Each mole of N₂ generates 2 moles of Li₃N. Thus,
0.08 moles of Li₃N will require:
0.08 / 2
= 0.04 moles of N₂
The second option is correct.
