The following compounds and the number and type of ions are as follows:
Gold and chloride:
Gold (III) = Au 3+
Chloride = Cl 1-
Calcium and Sulfate:
Calcium Sulfate:
Calcium = Ca 2+
Sulfate = SO4 2-
Magnesium and Hydroxide
Magnesium Hydroxide: Mg(OH)2
Magnesium: Mg 2+
Hydroxide: (OH) 1-
Answer:
1. Animal cells are eukaryotic
2. All live things are made up of cells (I think)
3. Cells are the basic unit of all living things
Explanation:
Number 2 is probably wrong because I can't see the diagram but, all living things ARE actually made up of cells
<span>Answer:
Enthalpy Change = (6 x -393.5) + (7 x -285.8) - (-204.6) + (19/2) 0.....???
like.. (6 x Enth CO2) + ( 7 x Enth H2O) - (Enth C6H14) + (19/2) Enth O2</span>
Hey there!
mass of sample = 2.51 g of Aspirin
Number of moles of base ( NaOH ) :
M*V = 27.36*0.5106 = 13.9700 mmol of base
M*V = 13.68*0.516 = 7.05888 mmol of acid
pKa calculation:
pH = pKa + log(A-/HA)
3.48 = pKa + log(7.05888 / (13.9700 -7.05888))
Pka =3.49 - log(7.05888 / (13.9700 -7.05888))
pKa = 3.48
Molar mass calculation:
molar mass = mass/mol
(2.51)/(13.9700 *10⁻³) =
molar mass 180 g/mol approx
Hope that helps!
