Answer:
3 × 10²⁰ molecules C₉H₃O₄
Explanation:
Step 1: Define
Avagadro's Number: 6.02 × 10²³ atoms, molecules, formula units, etc.
Molar Mass C - 12.01 g/mol
Molar Mass H - 1.01 g/mol
Molar Mass O - 16.00 g/mol
Molar Mass C₉H₃O₄ - 175.12 g/mol
Step 2: Use Dimensional Analysis
= 3.43764 × 10²⁰ molecules C₉H₃O₄
Step 3: Simplify
We are give 1 sig fig.
3.43764 × 10²⁰ molecules C₉H₃O₄ ≈ 3 × 10²⁰ molecules C₉H₃O₄
Electrons basically ARE the chemical bond. The atoms are joined together by the bonds.
Answer:
The correct option is: a. Photosphere
Explanation:
Sun is the brightest star in the sky of our planet Earth and the principle component of the Solar System. It is a <u>gaseous object</u> that is made up of hot plasma and contributes 99.86% to the total mass of our Solar System.
<u>The Sun does not have a clearly defined surface.</u> The <u>visible surface of the Sun is known as the Photosphere</u>, which is the deepest visible portion of the Sun.
Answer:
The answer would be beryllium
You were probably confused but the correct answer would actually be a beryllium ion.
Explanation:
Moles of N2 = 84/28 = 3.0mol
Moles of H2 = 29/2 = 14.5mol
Hence amount of ammonia produced = 6.0 * 17 = 102g.
