<h3>
Explanation:</h3>
<u>Step 1: Define</u>
2.68E24 atoms Mo or 2.68 × 10²⁴ atoms Mo
<u>Step 2: Identify Conversions</u>
Avogadro's Number
Molar Mass of Mo - 95.94 g/mol
<u>Step 3: Convert</u>
<u />
= 426.966 g Mo
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
426.966 g Mo ≈ 427 g Mo
The Equation of reaction
C + O2 === CO2
First Blank spot would be
---- 3.5moles of O2
2nd spot
Up.... 1mole of CO2
Down ---- 2moles of Oxygen atoms
3rd spot
Up... --- 22.4L of CO2(1mole of any gas at STP contains 22.4L)
Down---- 1mole of CO2
Final answer --- 3.5 x 1/2 x 22.4
=39.2L of CO2
No, xenon will not react on Nitrogen because xenon only reacts with oxygen and fluorine. Xenon only reacts with the 2 elements because these 2 elements contain a strong electronegative element which is high in energy barrier that can move the electrons inside xenon elements. Xenon is an element with a symbol of Xe, it is odorless and colorless gas. Common uses of xenon are flash lamps and arc lamps. Xenon is a luminous element, it glows when placed near to high voltage electric field.
