Its unstable and flammable... the Hindenberg used it... we saw how that went
Answer:
5.158 × 10²³ atoms K
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
- Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
Explanation:
<u>Step 1: Define</u>
33.49 g K
<u>Step 2: Identify Conversions</u>
Avogadro's Number
Molar Mass of K - 39.10 g/mol
<u>Step 3: Convert</u>
<u />
= 5.15797 × 10²³ atoms K
<u>Step 4: Check</u>
<em>We are given 4 sig figs. Follow sig figs and round.</em>
5.15797 × 10²³ atoms K ≈ 5.158 × 10²³ atoms K
Answer: C) The mass stays constant as it changed from a liquid to a gas
Explanation: Mass stays constant, it's never destroyed or created. It follows the law of conservation of mass.
Water is a liquid which was made from a gas but if you freeze it you would get a solid but if you leave it in a warm place you would get a liquid so that is the intensive property of a sample of water.<span />
