question 3 (1 point)
what is the formula of a made - up compound called wixum phosphate? wixums symbol is wx and is found in group 1a.
o a wx3(po)4
o b wxpo4
o c wx3(po4)2
o d wxpo4

question 4 (1 point)
your teacher discovered a new transition metal and named it buzhium, (bu). what would be the formula for buzhium (ii) oxide?
o a buo2
o b buo
o c bu2o

Explanation:

Step1: Determine charge of Wixum

Wixum is in group 1A, so it has a +1 charge, $Wx^+$. Phosphate ion is $PO_4^{3 - }$. To form a neutral compound, we need 3 Wixum ions for every 1 phosphate ion.

Step2: Write formula for Wixum phosphate

The formula is $Wx_3PO_4$.

Step3: Determine charge of Buahium(II)

Buahium (II) has a +2 charge, $Bu^{2+}$. Oxygen has a -2 charge, $O^{2 - }$. In a neutral compound, the ratio of Buahium(II) to oxygen is 1:1.

Step4: Write formula for Buahium(II) oxide

The formula is $BuO$.

Answer:

Question 3: c. $Wx_3PO_4$
Question 4: b. $BuO$
