Question

BaCl2 (aq) and K2CrO4 (aq) combine in a double replacement reaction. Select the reaction below that correctly represents the products of the reaction.

Answer 1

where is the "select below' part??

Answer 2

BaCl2 (aq) + K2CrO4 (aq) BaCrO4 (s) + 2KCl (aq)
BaCl2 (aq) + K2CrO4 (aq) BaCrO4 (s) + KCl (aq)
BaCl 2 (aq) + K2CrO4 (aq) BaCrO3 (s) + 2KCl (aq) + O (g)
BaCl2 (aq) + K2CrO4 (aq) Ba (s) + 2KCl (aq) + 2Cr (s) + 2O2 (g)

Answer 3

thats better thank you now I might beable too help you :)

Answer 4

i hope so :)

Answer 5

Let me give you an overall answer. Consider AX + BY --> AY + BX whenever faced with a reaction of two compounds, try switching the anions between the two cations. This will be a reaction if the resultant products are 1) a solid (precipitation) 2) a gas or 3) a slightly ionized compound like water. You will have to know your solubility rules.

Answer 6

ok that kind of helps , i just need to know which one it is out of the choices

Answer 7

Use the equation AX + BY --> AY + BX

Answer 8

Oh my goodness, are you on Study Island, too?!?!
