How many H atoms in 12H2O?
Ilya [14]

Answer:

24 atoms of H  or 1.4 x 10²⁵ hydrogen atoms

Explanation:

simple method

1 H₂O has  atoms of hydrogen and 1 atom of oxygen

while 12H₂O will have 24 atoms of hydrogen and 12 atom of oxygen

by Avagadros number

molar mass of water H₂0=18.01528 g/mol

1 mole of H₂0 have 2 moles of Hydrogen  

one mole of water= 6.02⋅10²³water molecules =1.2 x 10²⁴hydrogen atoms

12 mole of H₂O   =    1.2 x 10²⁴ x 12=  1.4 x 10²⁵ hydrogen atoms  

<u />

1.4 x 10²⁵ hydrogen atoms   in 12 moles of H₂O

<u />

Which pair of elements can form ionic bonds?
Sindrei [870]

Answer:

E.  potassium (K) and bromine (Br)

Explanation:

An ionic bond is formed between compounds with a large electronegativity difference between them. It is usually between a metal and non-metal.

  • Potassium is a true metal found in group 1 on the periodic table.
  • Bromine is a highly electronegative non-metal which is a halogen.
  • Potassium will lose one of its electrons which will be gained by the Bromine.
  • The electrostatic attraction between the two species will cause the ionic bond to form.
  • The ability of one specie willing to lose electron and the other gaining, is the main bed rock of ionic bonding.

What is the number of protons and electrons in a neutral atom of<br> Lithium?
nadya68 [22]
If you look at the periodic table you will see the atomic number (the smaller number) which is 3. that identifies how many protons there are. since the lithium is neutral that means there’s a same amount of electrons.

therefore there’s 3 electrons and 3 protons
