Answer:
Synthesis Reaction
General Formulas and Concepts:
<u>Chemistry - Reactions</u>
- Synthesis Reactions: A + B → AB
- Decomposition Reactions: AB → A + B
- Single-Replacement Reactions: A + BC → AB + C
- Double-Replacement Reactions: AB + CD → AD + BC
Explanation:
<u>Step 1: Define</u>
RxN: 2Na + I₂ → 2NaI
<u>Step 2: Identify</u>
2Na + I₂ → 2NaI
A + B → AB
Synthesis Reaction
Answer:
a chemical reaction or other process in which the products themselves promote or spread the reaction, which under certain conditions may accelerate dramatically.
Explanation:
the self-sustaining fission reaction spread by neutrons which occurs in nuclear reactors and bombs.
a series of events, each caused by the previous one.
Molarity
a. Na2CO3
Molar mass = 106 g/mol
n= 109 g / (106 g/mol) = 1.028 mol
b. 6.00L
c. M=n/V
M = 1.028 mol / 6.00 L
M= 0.1713 mol / L
Answer: The molarity of the sodium carbonate solution is 0.1713 mol/L
<h2>Gas Molecules Move in Random Motion </h2>
Explanation:
- According to the property of an ideal gas the volume occupied by the gas molecules themselves is negligible as compared to the volume occupied by the gas
- The molecules of ideal gas obey Newton's laws of motion thus they move in random motion
- According to the above statements we can conclude that Helium gas can fill many more balloons as compared to fit the baloons inside the cylinder because the particles of gas is free to move in random motion and can occupy more volume
Atoms. Well, they can be broken down, but that won't happen that fast.
