Which is the correct net ionic equation for the following reaction: 2hi (aq) + ca (oh)2 (aq) imported asset cai2 (aq) + h2o (l)?
a. h+ (aq) + ca+2 (aq) + 2 i− (aq) imported asset cai2 (aq)
b. ca+2 (aq) + 2 oh− (aq) imported asset ca(oh)2 (aq)
c. h+ (aq) + oh− (aq) imported asset h2o (l)
d. 2hi (aq) + ca (oh)2 (aq) imported asset cai2 (aq) + h2o (l)

The correct answer is option c

Explanation:

Hello!

Let's solve this!

The reaction is a neutralization reaction:

2HI (aq) + Ca (OH) 2 (aq) ---> CaI2 + H2O

Where CaI salt is formed with iodine and calcium and on the other hand water is formed.

In the formation of water we have to:

H + (aq) + OH-2 (aq) > H2O (l)

So we conclude that the correct answer is option c

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
