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

  • A = Na
  • B = I₂
  • C = NaI

Suppose you wanted to dissolve 109 g of sodium carbonate in enough water to make 6.00 L of solution. What is the molarity of thi
kumpel [21]
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

A small gas cylinder of Helium can be used to fill many more balloons than would fit inside it. Explain how this works, in your
Fudgin [204]
<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
