How are methane and propane alike

2 answers:

Both are carbon chains made of just Carbon and Hydrogen. Both contain saturated bonds (sigma bonds). Both contain carbons that have spy hybridized orbitals. Both exhibit the combustible property of making carbon dioxide and water vapor when reacted (burned) with oxygen gas. Propane is a 3 carbon chain, while methane is just one carbon. Essentially, propane is just a longer version of methane, in that propane just includes more carbons.

The density of ice is 917 kg/m3. The density of salt water is 1029 kg/m3. A mass of ice is 2.55 x 1013 kg. Calculate the volume

Ksju [112]

Answer:

Volume of salt water, $V_{sw} = 247.74 km^3$

Explanation:

Density of Ice, $\rho_{ice} = 917 kg/m^3$

Density of salt water, $\rho_{sw} = 1029 kg/m^3$

Volume of ice, $V_{ice} = 278 km^3$

Volume of salt water, $V_{sw} = ?$

Mass = Density * Volume

Mass of Ice, $m_{ice} = \rho_{ice}V_{ice}$

Mass of Salt water, $m_{sw} = \rho_{sw}V_{sw}$

Since , $m_{ice} = m_{sw}$

$\rho_{ice}V_{ice} = \rho_{sw}V_{sw}\\\\(917*278) = (1029*V_{sw})\\\\V_{sw} = \frac{254926}{1029} \\\\V_{sw} = 247.74 km^3$

Give the ground-state electron configuration for each of the following elements. After each atom is its atomic number in parenth

Anni [7]

Answer:

(a) ₁₉K: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹

(b) ₁₀Ne: 1s² 2s² 2p⁶

---

(a) 3

(b) 6

(c) 7

Explanation:

We can state the ground-state electron configuration for each element following Aufbau's principle.

(a) ₁₉K: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹

(b) ₁₀Ne: 1s² 2s² 2p⁶

Second part

(a) Al belongs to Group 13 in the Periodic Table. It has 13-10=3 electrons in the valence shell.

(b) O belongs to Group 16 in the Periodic Table. It has 16-10=6 electrons in the valence shell.

(c) F belongs to Group 17 in the Periodic Table. It has 17-10=7 electrons in the valence shell.
