What is the net ionic equation of Na2SO4(aq) + CaCl2(aq) = CaSO4(s) + NaCl(aq)

By converting the compound to the ionic form, ionic equation can be given.

Explanation:

Ionic equation for a reaction represents the change in ionic state of the elements involved in reaction.

The balanced ionic equation can be written when the number of ions for substrate and product for each element are equal.

The compounds are first breakdown into an ionic form for the ionic reaction:

iONIC EQUATION:

2Na2+ +SO42-+2Cl-+ Ca2+ Ca2+ + SO42-+ 2Na+ +2Cl-  

Explanation:

The balanced equation for the given reaction is:

Na2SO4+CaCl2 CaSO4+2 NaCl

Na2SO4 will dissociate as 2Na2+ +SO4^2-

CaCl2  will dissociate as Ca2+ + 2Cl-

The two salts formed will precipitate.

we must consider that these substances are water soluble.

The ionic equation is:

2Na2+ +SO42-+2Cl-+ Ca2+ CaSO4+2NaCl

2Na2+ +SO42-+2Cl-+ Ca2+ Ca2+ + SO42-+ 2Na+ +2Cl-

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
