The answer is B.
Tetraphosphorus is written as P4, and decaiodide as I10, so when you put them together, it's P4I10
Answer:
a. 0.0855 M
b. 0.153 M
c. 0.0351 M
d. 0.0901 M
Explanation:
a.
Molar mass NaCL= 23.0 +35.5 = 58.5 g/mol
10.0 g* 1 mol/58.5 g = 10.0/58.5 mol
(10.0/58.5) mol/2L = 0.0855 mol/L = 0.0855 M
b.
Molar mass (C12H22O11) =342.3 g/mol
52.5 g*1mol/342.3 g = 52.5/342.3 mol=0.153 mol
0.153 mol/1L = 0.153 M
c.
Molar mass (Al2(SO4)3) =342.2 g/mol
120g* 1 mol/342.2 g =0.351 mol
0.351 mol/10.0L = 0.0351 mol/L = 0.0351 M
d.
Molar mass (C8H10N4O2) = 194.2 g/mol
1.75 g*1mol/194.2 g = 0.00901 mol
0.00901 mol/0.100 L =0.0901 M
NI(s)->NI^2+(aq)+2e^-(oxidation)
Answer:
Here's what I get
Explanation:
Both diamond and SiO₂ are network solids. Their atoms are all joined together so a crystal of either diamond or SO₂is one giant molecule.
Structure
In diamond, each C atom is covalently attached to four other C atoms.
The structure of SiO₂ is like that of diamond. The difference is that there is an O atom between each atom of Si.
Properties
Both substances are
- High-melting
- Hard
- Insoluble in both polar and nonpolar solvents
- Poor conductors of electricity
