Answer:
gases
Explanation:
Their atoms are the least far apart
This is going to take a while..
1. 2AgI + Na2S --> Ag2S + 2NaI
2. Na3PO4 + 3HCl --> 3NaCl + N3PO4
3. Ba3N2 + 6H2O --> 3Ba(OH)2 + 2NH3
4. TiCl4 + 2H2O --> TiO2 + 4HCl
5. 3CaCl2 + 2Na3PO4 --> Ca3(PO4)2 + 6NaCl
6. 2NaBr + Cl2 --> 2NaCl + Br2
7. Mg(OH)2 + 2HCl --> MgCl2 + 2H2O
Hopefully that helps.
Answer:
(a) Ionic
(b) Nonpolar covalent
(c) Polar covalent
(d) Polar covalent
(e) Nonpolar covalent
(f) Polar covalent
<em>For those substances with polar covalent bonds, which has the least polar bond?</em> NO₂
<em>For those substances with polar covalent bonds, which has the most polar bond?</em> BF₃
Explanation:
<em>Are the bonds in each of the following substances ionic, nonpolar covalent, or polar covalent?</em>
The nature of a bond depends on the modulus of the difference of electronegativity (|ΔEN|) between the atoms that form it.
- If |ΔEN| = 0, the bond is nonpolar covalent.
- If 0 < |ΔEN| ≤ 2, the bond is polar covalent.
- If |ΔEN| > 2, the bond is ionic.
<em>(a) KCl</em> |ΔEN| = |EN(K) - EN(Cl)| = |0.8 - 3.0| = 2.2. The bond is ionic.
<em>(b) P₄</em> |ΔEN| = |EN(P) - EN(P)| = |2.1 - 2.1| = 0.0. The bond is nonpolar covalent.
<em>(c) BF₃</em> |ΔEN| = |EN(B) - EN(F)| = |2.0 - 4.0| = 2.0. The bond is polar covalent.
<em>(d) SO₂</em> |ΔEN| = |EN(S) - EN(O)| = |2.5 - 3.5| = 1.0. The bond is polar covalent.
<em>(e) Br₂</em> |ΔEN| = |EN(Br) - EN(Br)| = |2.8 - 2.8| = 0.0. The bond is nonpolar covalent.
<em>(f) NO₂</em> |ΔEN| = |EN(N) - EN(O)| = |3.0 - 3.5| = 0.5. The bond is polar covalent.
To convert weight to moles, we must use the molar weight found on the periodic table. Sulfur's (S) molar weight is 32.06 g/mol. Then we set up an equation and cancel out units:
So now we know that 0.994g of sulfur is equal to 0.031 moles.
Answer:
The molarity of the HCl solution is 4M.
Explanation:
Hence, the molarity of the HCl solution = 4 M
