Answer:
accelerating
Explanation:
technically, there is no such thing as deceleration, just negative acceleration.
Answer:
A law is a proven fact that can not be changed.
Explanation:
Scienctists are most inquisitive in their research and as such they developed what is called scientific method which they use to create and learn new things. The scientific method includes:
1. Observation.
2. Hypothesis.
3. Experiment
4. Conclusion.
5. Law.
Among this scientific method, the law is the last in the pattern. A law is only given after the experiment has been tested over and over again and found to be true.
<u>Given:</u>
Mass of Na = 115 g
Excess Cl2
<u>To determine:</u>
Mass of NaCl produced
<u>Explanation:</u>
Given reaction is-
2Na(s) + Cl2(g) → 2NaCl(s)
Since Cl2 is in excess, Na will be the limiting reagent
As per the reaction stoichiometry Na:NaCl = 1:1
i.e. moles of Na reacted = moles of NaCl formed
Now, # moles of Na = mass of Na/atomic mass
= 115 g/23 g.mol-1 = 5 moles
Therefore, moles of NaCl = 5
Molar mass of NaCl = 58 g/mol
Mass of NaCl = 5 moles * 58 g.mol-1 = 290 g
Ans: Amount of Nacl produced = 290 g
