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)
Answer:
Anthracite coal
Explanation:
Anthracite coal has highest amount of carbon and has clean burning properties. So, it is used as a household coal.
Explanation:
Ka is the acid dissociation constant. pKa is simply the -log of this constant.
Mathematically;
pKa = - log Ka
Ka = 10^-pKa
a. acid a has a pka of 6.0 what is its ka?
Ka = 10^-6 = 10⁻⁶
b. acid b has a pka of 8.60 whats its ka?
Ka = 10^-8.6 = 2.51e⁻⁹
c. acid c has a pka of -2.0 whats its ka?
Ka = 10^-(-2) = 10^2 = 100
