Answer: Ionic formula will be
.
Explanation:
and
ions will form a ionic compound. Ionic compounds have both metals and non-metals.
Here
is a metal and
is a non-metal.
The net charge on any compound must be 0.
So we need 2 phosphate ions to balance the charge on
ions. Similarly we need 3 Magnesium ions to balance the charge on
ions.
Criss-crossing the charges, we will get the formula as 
Criss-crossing is shown in the image below.
CuCl2 + 2NaNO3 ----> Cu(NO3)2 + 2NaCl
using molar masses:-
Theoretical yields:-
63.54 + 2(35.45) g of CuCl2 produces 2(22.98 + 35.45) g of NaCl
134.44 g .................................................... 116.86 g
31.0 g ....................................................31.0 * 116.86 /134.44=26.95g
So percentage yield is 21.2* 100 / 26.95 = 78.7% to nearest tenth
Answer:

Explanation:
Hello,
In this case, since the density is defined as the ratio of the mass and volume:

We can compute the mass of blood as follows:

Best regards.
Answer:
water, lead, and wood
Explanation:
All are correct on Edg 2020
Answer:
A = Metallic Bond
B = Strong bonding, strong conductor, high melting and boiling points
Explanation:
Since the bond is between two metals (located in groups 11 and 12), they would experience metallic bonding. Metallically bonded molecules have high melting and boiling points due to the strength of the metallic bond. They also experience strong electrical current due to the there delocalized electrons.
