<span>3. MgCl2 For each salt, determine what acid and base were used to create it by separating the salt into it's cation and anion. From there, determine the acid and base used to create the salt by adding the appropriate number of hydroxyl group(s) to the cation and hydrogen to the anion. So: LiClO4 -> Li, ClO4 -> LiOH + HClO4. LiOH is a strong base, and HClO4 is a strong acid. CsBr2 -> Cs, Br2 -> CsOH + HBr2 CsOH is a strong base, and HBr2 is a strong acid. MgCl2 -> Mg, Cl2 -> Mg(OH)2 + HCl Mg(OH)2 is not a strong soluble base HCl is a strong acid. Therefore MgCl2 is the correct salt. Ba(NO3)2 -> Ba, NO3 -> Ba(OH)2 + HNO3 Ba(OH)2 is a strong base, and HNO3 is a strong acid. NaI -> Na, I -> NaOH + HI NaOH is a strong base, and HI is a strong acid.</span>

I believe the answer is MgCl, this is because the bases of group one elements (alkali metals) such as sodium, lithium , and cesium, are all strong bases unlike those of group 2 and group 3. The bases of group one elements ( NaOH, LiOH, CsOH) all readily dissolve in water forming strong soluble base. Then between a base of Ba (Ba(OH)2)and that of Mg, (Mg(OH)2), the one for Ba is more stronger because Ba is more reactive than that of Mg because it is not readily dissolve in water ( less soluble in water to give OH- ions)

The mass fractions of a mixture of gases are 15 percent nitrogen, 5 percent helium, 60 percent methane, and 20 percent ethane wi
Setler79 [48]

Answer:

Explanation:

mass fraction N₂ : He : CH₄ : C₂H₆ : : 15 : 5 : 60 : 20

mole fraction  N₂ : He : CH₄ : C₂H₆ : : 15/28 : 5/4 : 60/16 : 20/30

mole fraction  N₂ : He : CH₄ : C₂H₆ : : .5357  : 1.25 : 3.75 : .67

Total mole fractions = .5357 + 1.25 + 3.75 + 0.67 = 6.2057

mole fraction of N₂ =  .5357 / 6.2057 = .0877

mole fraction of He = 1.25 / 6.2057 = .20

mole fraction of CH₄ = 3.75 / 6.2057 = .6043

mole fraction of C₂H₆ = .67 / 6.2057 = .108

Partial pressure = total pressure x mole fraction

Partial pressure of N₂ = 1200 kPa  x .0877 = 105.24 kPa

Partial pressure of He = 1200 kPa  x .20  = 240 kPa

Partial pressure of CH₄ = 1200 kPa  x  .6043  = 725.16 kPa

Partial pressure of C₂H₆ = 1200 kPa  x .108    = 129.6 kPa

When naming a compound made from a metal and a non-metal, what is done to the name of the second element?
RoseWind [281]
Metals combine with nonmetals to give ionic compounds. When naming binary ionic compounds, name the cation first (specifying the charge, if necessary), then the nonmetal anion (element stem + -ide). Hope this helps!
