[HELP PLEASE]What is the electronegativity from largest to smallest for Chlorine [Cl], Carbon [C], and Arsenic [As]? (hint: use
valentina_108 [34]

Answer:

Electronegativity varies in a predictable way across the periodic table. Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.Explanation:

There are some data that suggest that zinc lozenges can significantly shorten the duration of a cold. If the solubility of zinc
zhuklara [117]

Answer:

K_{sp} of Zn(CH_{3}COO)_{2} is 0.0513

Explanation:

Solubility equilibrium of Zn(CH_{3}COO)_{2}:

Zn(CH_{3}COO)_{2}\rightleftharpoons Zn^{2+}+2CH_{3}COO^{-}

Solubility product of Zn(CH_{3}COO)_{2} (K_{sp}) is written as-            K_{sp}=[Zn^{2+}][CH_{3}COO^{-}]^{2}

Where [Zn^{2+}] and [CH_{3}COO^{-}] represents equilibrium concentration (in molarity) of Zn^{2+} and CH_{3}COO^{-} respectively.

Molar mass of Zn(CH_{3}COO)_{2} = 183.48 g/mol

So, solubility of Zn(CH_{3}COO)_{2} = \frac{43.0}{183.48}M = 0.234M

1 mol of Zn(CH_{3}COO)_{2} gives 1 mol of Zn^{2+} and 2 moles of CH_{3}COO^{-} upon dissociation.

so,   [Zn^{2+}] = 0.234 M and [CH_{3}COO^{-}] = (2\times 0.234)M=0.468M

so, K_{sp}=(0.234)\times (0.468)^{2}=0.0513

What is the mass of 3.25 mol of h2so4
Setler [38]

Answer/ explanation :

The find the mass,

We use this formula

Number of mole = mass/ molar mass

Since number of mole = 3.25mol

Number of mass be x

Molar mass of H2SO4

H - 1.00784 * 2= 2.01568

S - 32.065

O - 15.999 * 4 = 63.996

Note there are 2 moles of H and 4 moles of O and 1 mole of S

Molar mass of H2SO4 = 2.01568 + 32.065 + 63.996

= 98.07668g/mol

Number of mole= 3.25mol

3.25 = x / 98.07668

x = 3.25 * 98.07668

= 318.749g

Therefore, the number of mass is 318.749g
