Answer:
Write the balanced reaction equation. From this, note the mole ratio of Na to H₂; this enables you to know the number of moles of H₂ produced.
This technique is in your lecture notes and/or your chemistry textbook, so you should not have to ask Quorans to do your homework. (Take the hint.)
Explanation:
Answer:
Anion is negatively charged particle.
Calcium +2. Its cation
Oxygen -2
Explanation:
An anion is a charged particle with a negative charge. Anions has charge of -1
Oxygen require two electrons to complete its octet and hence its charge is -2
Calcium is a cation and has a positive charge of +2
Answer:
lower ionization should be the answer
