Answer:
Explanation:
There are three fundamentally known states of matter save for plasma and the Bose-Einstein condensate. These states of matter are solid, liquid and gas.
We can classify nearly all matter into these discrete categories based on certain lucid characteristics they exhibit.
- Solids have definite shape and volume and they exhibit by the far the most remarkable internal ordering. Their molecules are attached by strong internal forces.
- Liquids do not have a definite shape but takes the shape of the contains that hold them. They are not random and have internal cohesion among them.
- Gases are random particles and highly varied. They move haphazardly and have no definite shape and volume.
Answer:
Mass = 234 g
Explanation:
Given data:
Mass of NaCl produced = ?
Moles of chlorine = 2.0 mol
Solution:
Chemical equation:
2Na + Cl₂ → 2NaCl
now we will compare the moles of NaCl with chlorine gas.
Cl₂ : NaCl
1 : 2
2.0 : 2/1×2.0 = 4.0 mol
Mass of NaCl;
Mass = number of moles × molar mass
Mass = 4.0 mol × 58.5 g/mol
Mass = 234 g
1) D) The amount of space a substance takes up
2) A) The amount of matter in a substance
