Haha i’m trying to do the same one i’ll make sure if i find out how too to get back to you!
It smells so bad that no one or animal will get near it
Answer:
25.8
Explanation:
Let's write the reaction between magnesium-phosphide and potassium:
Mg3P2 + K = Mg + K3P
And now let's balance this equation:
Mg3P2+6K=3Mg+2K3P
We see that the ratio of magnesium-phosphide and potassium is 1:6, which means that for every mole of magnesium-phosphide there need to be 6 moles of potassium.
Since we have 4.3 moles of Mg3P2, there need to be 6 • 4.3 = 25.8 moles of potassium.
C) It contains the same number of electrons and protons.
The 3 indicates the third electron shell. (Which has only 1 electron in it in this configuration)
Hope this helps! :)
