Write the ions present in a solution of K2CO3. Express your answers as chemical formulas separated by a comma. Offset subscripts
meriva

Answer:

K ^+ , CO3 ^2-

Explanation:

The compound is potassium trioxocarbonate(IV).

It contains cation (potassium ion) and acid radical ( trioxocarbonate (IV) ion).

Since K is in group 1 of the periodic table, it loses one electron to form ion i.e K^1. trioxocarbonate IV ion has a charge of 2-.and so the ions of the compound are as shown in the answer above.

Given the following reaction:
Elan Coil [88]

(Answer) 0.166 moles of copper (I) nitride are needed.

Mass of copper (I) oxide = 35.7 g

Moles of copper (I) oxide formed by the reaction = (Mass / molar mass)

= ( 35.7 g / 143.09 g/mol ) = 0.25 moles

According to the balanced chemical equation,

mole ratio of copper (I) nitride and copper (I) oxide = 2: 3

Therefore, moles of copper (I) nitride needed to form 0.25 moles of copper (I) oxide = (2/3 x 0.25) moles = 0.166 moles.

Thus, 0.166 moles of copper (I) nitride are needed to form 0.25 moles of copper (I) oxide.
