Why does hybridization of orbitals occur?
Answers
Hybridization of orbitals is the concept of incorporation atomic orbitals into new hybrid orbitals appropriate for the pairing of electrons to form chemical bonds in valence bond theory.

Answer is: C. nitrogen.
Together, nitrogen (N₂) and oxygen (O₂) by volume account for 99.03% volume of the gases composing the dry air in the lower atmosphere.
Volume of nitrogen in air is 78.08%.
Volume of oxygen in air is 20.95%.
Together: 78.08% + 20.95% = 99.03%.
This gases can be separated by fractional distillation of liquefied air.

So,
0.5 Wh = 0.5 (J/s) (h)
Converting h to s,
0.5 (J/s) (h) (60min/1h) (60s/1min) = 1800J
Thefore,
0.5Wh is 1800J or 1.8kJ of heat energy

No, unless you're doing some sort of course where they demand that you do. It's useful to remember the general features of the periodic table (what each block is, where they are in relation to each other, roughly where the most common elements are), but memorizing the entire thing would simply be a mnemonic exercise

Answer:
aqueous solutions of silver nitrate and sodium chloride turn cloudy after mixing aqueous solutions of hydrochloric acid and sodium hydrogen carbonate produces bubbles on mixing Sodium hydroxide is mixed with water and the container feels warmer
Explanation:
A chemical change involves the formation of new substances. Also heat is absorbed or released in a chemical change. Another name for a chemical change is a chemical reaction.
In the first case, a reaction of the sort;
AgNO3(aq) + NaCl(aq) ---> AgCl(s) + NaNO3(aq)
The cloudy solution is due to the formation of AgCl precipitate.
In the second case, a reaction of the sort;
HCl(aq) + NaHCO3(aq) ---> NaCl(aq) + CO2(g) + H2O(l)
The gas evolved is due to the formation of CO2 in the process. Heat is also evolved showing that it is a chemical change.

Answer:
- 146. g
Explanation:
1) Data:
a) mass of solute = ?
b) volume of solution = 1.25 liter
c) M = 2.92 mol/liter
d) solute NaOH
2) Formulae:
a) Molarity, M = number of moles of solute / volume of solution in liters
b) mass in grams = molar mass × number of moles
3) Solution:
a) Calculate number of moles of solute:
- M = number of moles of solute / volume of solution in liters
⇒ number of moles of solute = M × volume of solution in liters
⇒ number of moles of solute = 2.92 mol/liter × 1.25 liter = 3.65 mol
b) Molar mass of NaOH = 39.997 g/mol (you can take this number from internet or calculate it using the atomic masses of Na, O, and H).
c) Calculate the mass of solute:
- mass in grams = molar mass × number of moles = 39.997 g/mol × 3.65 mol = 145.98905 g = 146. g
The answer must be reported with 3 significant figures, so it is 146. g.
