Question

dentify the spectator ions in the following complete ionic equation.

Ba2+(aq)+2I−(aq)+2Na +(aq)+SO2−4(aq)→BaSO4(s)+2I−(aq)+2Na+(aq)

Answer 1

spectator ions are the ones that do not participate in the chemical reaction and therefore remain unchanged.

notice that Ba2+ and SO2-4 somehow combined to make BaSO4 while the I- and Na+ ions remain unaffected before and after the arrow. therefore they are said to be spectating

Answer 2

ok

Answer 3

so answer is ba2+, SO2-4

Answer 4

sorry I- and Na+

Answer 5

yes I- and Na+

Answer 6

can you help me with one more

Answer 7

A beaker of nitric acid is neutralized with calcium hydroxide.

Write a balanced molecular equation for this reaction.

Answer 8

is this it 2HNO3(aq) + Ca(OH)2(aq) --> Ca(NO3)2(aq) + 2H2O(l)

Answer 9

yes

Answer 10

its balanced and everything ^_^

Answer 11

Write a net ionic equation for this reaction.

Answer 12

H^+(aq)+ OH^-(aq) --> H2O(l)

Answer 13

it's right

Answer 14

ok
