Find ionic compounds ​

Chemistry
1 answer:
ella [17]3 years ago
3 0

Answer:

1:1

Explanation:

The ratio of metal cationic atom to non-metal anionic atom in the compound is 1:1.

This is an ionic compound.

  • This is because metal cationic atom has two valence electrons.
  • Non-metal anionic oxygen has six valence electrons
  • Calcium loses two of its valence electrons to be isoelectronic with Ar and this confers a stable configuration to it.
  • Non-metal oxygen atom accepts the electrons and adds 2 to its 6 electrons to become isoelectronic with neon.
  • So, 1 metal cationic atom combines with 1 non-metal anionic atom to form the compound.

What happens when HCl gas is passed through a saturated PbCl2 solution?
VikaD [51]
When HCl is added to a saturated solution of PbCl2, the solubility of PbCl2 would decrease so precipitation would occur. The decrease in the solubility is due to the common ion effect or the presence of Cl- ions in both compounds.

How many moles of S are in 35.4 g of (C3H5)2S?
alexandr402 [8]
<span>0.310 moles First, look up the atomic weights of the elements involved. Atomic weight carbon = 12.0107 Atomic weight hydrogen = 1.00794 Atomic weight sulfur = 32.065 Molar mass (C3H5)2S = 6 * 12.0107 + 10 * 1.00794 + 32.065 = 114.2086 g/mol Moles (C3H5)2S = 35.4 g / 114.2086 g/mol = 0.309959145 mol Since there's just one sulfur atom per (C3H5)2S molecule, the number of moles of sulfur will match the number of moles of (C3H5)2S which is 0.310 when rounded to 3 significant digits.</span>

Identify the limiting reactant when 32. 0 g hydrogen is allowed to react with 16. 0 g oxygen
Mkey [24]

Answer:

Oxygen is limiting reactant

Explanation:

2 H2  +   O2  ======> 2 H2 O

from this equation (and periodic table) you can see that

  4 gm of H combine with 32 gm O2  

     H / O  =  4/32 = 1/8

       32 /16    =  2/1    shows O is limiter

         for 32 gm H you will need 256 gm O   and you only have 16 gm
