C) S
Because of the trends of electronegativity. Increases across a period and decreases down a group.
if you are talking about the climate change of today as in the heat your answer would be ,because the green house gases are trapping in the heat and reflecting it back down it disrupts the temperature everywhere. so the hot weather will become even HOTTER the cold weather will become warmer of come to late ,and the places such as Greenland and Antarctica which are covered in snow will start to melt making the whole globe more hot year by year
The event that is known to have 'created' the universe was the Big Bang THEORY (because it can't be proven and most people just don't want to admit that there is a God)
Answer:
4.8 grams
Explanation:
Use PV=nRT
P: 775 mmHg (divide by 760 mmHg to get atm) -> 1.02 atm
V: 3700 mL (divide by 1000 to get L) -> 3.7L
n: ?
R: (a constant) 0.0821L * atm/k *mol
T: 33 C (add 273 to get K) -> 306K
Move equation so n is on the side: PV/RT = n. Plug the numbers into the equation.
Then, convert moles to grams using the molar mass of O2 which is 32g/mol.
= 4.8g
<span>Electrons (negatively charged) are found in almost all the matter we see. They "buzz" around positively charged atomic nuclei; you may be familiar with one not-very-correct representation of an atom.
