It is the s-orbital because the order of electrons is s-block, p-block, d-block, and f-block. The p, d, and I think f as well (not 100% about f though) can each hold 8 more valence electrons in their shells.
Answer: С
. The temperature increases by about 12°C and then decreases by about 12°C.
Explanation:
Temperatures around the world have been on the rise since the Industrial revolution as humans clog the planet with Carbon Dioxide and other pollutants. This had led to a rise in temperatures that has seen ice levels fall and sea levels rise around the world.
Temperature fluctuations on the other hand are not a new thing. Studies show that in Antarctica temperatures from about 440,000 years ago to about 340,000 years ago increased by 12°C and then decreased by about 12°C.
Hi!
To convert grams to moles, you need to divide the amount (grams) of your substance by its molar mass, both of which are given to you.
28 g CaO / 58.08 g/mol CaO = 0.4820936639 moles of CaO
(And 28 contains two significant digits, so you will round this to 0.48 moles.)
Good luck!
The answer is rings, I know this because i took a test about it and I got it right
Answer:
60%
Explanation:
Solute = the fruit juice = 75mL
Solution= solute + solvent = 75+50 = 125mL
% of solute = solute/ solution × 100 %
= 75/125 × 100 %
= 3/5 × 100 %
= 3 × 20 %
= 60%
