This for metal......the farther to the left the more reactive they are. Group 1 metals, which include sodium and potassium, are so highly reactive that they do not exist in nature by themselves

Thats non metals..........the farther to the right the more reactive they are *with the exception of group 18* which are the noble gases and do not react at all. The most reactive are group 17, which include fluorine and chlorine. These non-metals, like group 1, rarely exist by themselves because of their high reactivity.

Answer:

212.8 dm^3 or L

Explanation:

1 mole of any sub=6.02×10^23 molecules

X mole of O2=5.7×10^24 molecules

X mole=5.7×10^24/6.02×10^23

=9.5 mole

1 mole of any gas at stp=22.4 dm^3

Therefore, 9.5 mole of O2 will be 22.4×9.5

=212.8 dm^3

When a metal and a nonmetal exchange electrons to make a cation and an anion, respectively, they can form an ionic compound. The

mario62 [17]

Answer:

Generally, we know that ionic compounds are formed by reaction of metals and non metals and non metals form a covalent or non ionic bonds.

<u>IONIC COMPOUDS</u>

Iron and chlorine (FeCl2) , ( FeCl3)
Chlorine and Lithium (LiCl)
oxygen and calcium ( CaO)
Potassium and Sulphur ( K2S)

<u>NON IONIC COMPOUNDS</u>

Potassium and Calcium (covalent bond)
Sulphur and Bromine (covalent bond)

Answer:

Explanation:

Since they're changing from a gas to a liquid, the particles are getting squished together more if that makes sense. They're not vibrating that fast anymore when they're in liquid form.

The vibration of which bond gives an IR absorption that distinguishes between the following two compounds? CH3 CH2 CH2 OH CH3 CH

liq [111]

Answer: 3500cm-1

Explanation: The -OH bond absorbs IR and vibrates at a characteristic and many times distinctive wave number of 3500cm-1. The -C=O would vibrate at 1700cm-1 though not clearly because -C-O bond typically vibrates around this point
