Answer:
This question lacks options, the options are:
A. 2.89 x 1022
B. 8.66 x 1022
C. 3.66 x 1023
D. 1.10 x 1024
E. 3.29 x 1024
The answer is C. 3.66 × 10^23
Explanation:
In the chemical compound given as follows: Co2(HPO4)3, hydrogenphosphate ion is (HPO4)3.
Number of moles of hydrogenphosphate ion can be calculated using the formula
mole (n) = mass (m) /molar mass (MM)
Molar mass of (HPO4)3;
{1 + 31 + 16(4)}3
= {32 + 64)3
= (96)3
= 288g/mol
mole = 175/288
mole = 0.6076
mole = 0.607mol
The formula of units of hydrogenphosphate ion can be calculated by multiplying number of moles by Avogadro's number (6.022 × 10²³)
6.022 × 10²³ × 0.607
= 3.655 × 10²³
= 3.66 × 10²³
Answer: 
is missing
Explanation:
In a nuclear reaction, the total mass and total atomic number remains the same.
For the given reaction:
To calculate A:
Total mass on reactant side = total mass on product side
4 + 9 = 12 + A
A = 1
To calculate Z:
Total atomic number on reactant side = total atomic number on product side
2 + 4 = 6 + Z
Z = 0
Hence, missing is .
The particles are given more energy and start to vibrate faster. In certain temps the particles vibrate so much that their ordered structure breaks down to the point the solid melts into liquid

Once a chemical bond is formed, the atoms are rearranged to form a stronger bond, affecting the hardness, malleability, etc. The stronger the bond, the easier a substance will break, or, if its a liquid, it will resist seperation.
