photo is blurred plese send photo clearly
The molarity is 31.0 * x / 2, such that x is the molar mass of Ca₃(PO₄)₂
The picture of correct answer is attached it is the second one from the left since it has 5 electrons in outermost shell so it can share 3 electrons to complete the octet rule, while first one contains only one electron in outermost shell so it easier to be lost, third one has 8 electrons so it has complete valence shell and last one with only two electrons in outermost shell so it is easier to lose these two electrons.
from 5 to 7 electrons on outermost shell can form covalent bond
Answer:
It's balanced but not in the lowest form
Explanation:
The actual equation is given by


Moles of copper nitrate:-

- 1mol of Copper nitrate reacts with 2mol NaOH
- 0.001mol will react with 0.002mol NaOH
Madd of NaOH
