Give two reasons why the actual yield would be smaller than the theoretical yield.

suppose a 100mL solution was prepared using 2.2g of copper ore, but in order to fit on your Beer's Law plot, you had to take a 10mL portion and dilute it to 500mL. The resulting solution had an absorbance value of 0.42. Determine the initial molarity of the 100mL solution and the percent copper in the sample

A 1.75-L sample of H2S measured at 25.0°C and 625 mmHg is mixed with 5.75 L of O2, measured at 10.0 °C and 715 mmHg, and the mixture is allowed to react. 2 H2S(g) + 3 O2 (g) → 2 SO2 (g) + 2 H2O (g) How much H2O in grams, is produced?

The figure below shows the structure of La0.20Sr0.80MnO3 perovskite. At room temperature, it has a cubic unit cell with a lattice parameter a = 3.82 Å. O sites are white, mixed La/Sr sites are light grey, and Mn sites are dark grey. The arrows represent the so-called C-type antiferromagnetic(AFM) structure that appears below the Néel temperature TN = 230 K, in which the magnetic moments of unpaired electrons on Mn are aligned into chains with parallel spins along the z direction, and each chain has spins antiparallel to those of its neighbours in the x and y directions.
Suggest a combination of magnetic exchange interactions that could give rise to the C-type
AFM state in this compound, and explain how those exchange interactions work. Your
answer should consider the configuration of Mn electronic orbitals, including crystal-field
splitting, and their interactions with O electronic orbitals. Assume that Mn is high-spin.

berryllium compounds are mainly covalent where other grouo 2 compounds are predomiantly ionic. discuss the evidence for this statement ang suggest factors that contribute to it

The reaction of iron(III) oxide with carbon monoxide occurs in a blast furnace when iron ore is reduced to iron metal:Fe2O3(s) + 3 CO(g) ⇌2 Fe(l) + 3 CO2(g)Use Le Ch telier’sprinciple to predict the direction of reaction when an equilibrium mixture is disturbed by

When 0.25 L of liquid nitrogen (d = 0.807 g/mL) is vaporized, what volume does the resulting gas occupy at 25 °C and 5.00 atm

Why lithium has boiling point higher than its melting point ?
