When dynamic equilibrium is achieved, the rate of the forward and backward reactions go to zero. (T&F)
ratelena [41]

Answer:

1) False

2) there are equal amounts of rectants and products

Explanation:

1)  When dynamic equilibrium is achieved. the rate of forward and backward reaction they are the same, that is to say, two opposite reactions occur at the same rate, keeping the concentrations constant over time.  Different to say the rate of the ractions go to zero.

2)  A chemical equilibium exists when what is produce in quantities is equal to what reacts.

So the correct answer is the literal (d).

How much of glucose (C6H1206) is needed to make 1 L of a 1-M solution? Use details to support your answer.
Yakvenalex [24]

Answer:

200 g C₆H₁₂O₆

General Formulas and Concepts:

<u>Chemistry - Solutions</u>

  • Reading a Periodic Table
  • Using Dimensional Analysis
  • Molarity = moles of solute / liters of solution

Explanation:

<u>Step 1: Define</u>

1 M C₆H₁₂O₆

1 L of solution

<u>Step 2: Identify Conversions</u>

Molar Mass of C - 12.01 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar mass of C₆H₁₂O₆ - 6(12.01) + 12(1.01) + 6(16.00) = 180.18 g/mol

<u>Step 3: Find moles of solute</u>

1 M C₆H₁₂O₆ = x mol C₆H₁₂O₆ / 1 L

x = 1 mol C₆H₁₂O₆

<u>Step 4: Convert</u>

<u />1 \ mol \ C_6H_{12}O_6(\frac{180.18 \ g \ C_6H_{12}O_6}{1 \ mol \ C_6H_{12}O_6} ) = 180.18 g C₆H₁₂O₆

<u>Step 5: Check</u>

<em>We are given 1 sig figs. Follow sig fig rules and round.</em>

180.18 g C₆H₁₂O₆ ≈ 200 g C₆H₁₂O₆
