1.Magnesium (Mg) has two electrons in its outer shell. Mg will <span>try to give two electrons to another atom (because the Mg is metal).
</span>2. When an atom loses electrons, it becomes <span>positively charged because its protons outnumber its electrons. ( In an atom, number of protons = number of electrons, when electrons are lost, the number of protons >the number of electrons.)</span>
Answer:
Hello my friend! The amount of 31g of KNO3 will precipitate!
Explanation:
At 40 ∘C the solution has 45 g of KNO3 per 100 g of water and it can contain up to 63 g of KNO3 per 100 g of water. At 0 ∘C the solubility is ~ 14 gKNO3per 100 g of water, so 31 gKNO3 per 100 g of water will precipitate
