Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

<u>Stoichiometry</u>

Using Dimensional Analysis

<h3>Explanation:</h3>

<u>Step 1: Define</u>

[Given] 7.85 × 10²² molecules NH₃

[Solve] moles NH₃

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

Avogadro's Number

<u>Step 3: Convert</u>

[DA] Set up: $\displaystyle 7.85 \cdot 10^{22} \ molecules \ NH_3(\frac{1 \ mol \ NH_3}{6.022 \cdot 10^{23} \ molecules \ NH_3})$
[DA] Multiply/Divide [Cancel out units]: $\displaystyle 0.130355 \ moles \ NH_3$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

0.130355 moles NH₃ ≈ 0.130 moles NH₃

Why is geothermal energy not used as<br> frequently as other renewable energy source?

sasho [114]

Answer:

Because its source is the almost unlimited amount of heat generated by the Earth's core. Even in geothermal areas dependent on a reservoir of hot water, the volume taken out can be reinjected, making it a sustainable energy source.

Complete the balanced molecular chemical equation for the reaction below. If no reaction occurs, write NR after the reaction arr

Alex Ar [27]

Explanation:

The reaction is given as;

Pb ( N O ₃ ) ₂ (aq) + K I (aq) → Pb I ₂ + K N O ₃

To ensure the reaction is balanced, there has to be equal number of toms of each element present in both the reactant and product side of the reaction.

This leads us to;

Pb ( N O ₃ ) ₂ (aq) + 2 K I (aq) → Pb I ₂(s) + 2 K N O ₃(aq)

Ths way all atoms of elements are the same.
