3 0

Explanation:

you can use Born-Lande equation,

U=-(A×e^2×Z+ ×Z- ×N)\r ×(1-1/n)

here,U=lattice energy

A=madelung constant

n=Born exponent(depends on repulsion between ion)

e=charge of electron

Z+,Z-=charge of cation and anion

r=distance between cation and its neighbour anion in

space lattice

If 185 mg of acetaminophen were obtained from a tablet containing 350 mg of acetamino- phen, what would be the weight percentage
Alex73 [517]

Percentage recovery gives us an idea of the amount of pure substance recovered after the chemical reaction. Percentage recovery can be more than 100 % or less than 100 %. Usually, in any experiment performed the weight percentage recovery will be less than 100. Percent recovery values greater than 100 show that the recovered compound is contaminated.

Amount of acetaminophen initially taken = 350 mg

Amount of acetaminophen obtained after recovery =185 mg

Weight percentage recovery =\frac{mass recovered}{mass originally taken}*100

                                                = \frac{185 mg}{350 mg}*100

                                               = 52.9%

What cells do you think is in metaphase? why?
Tcecarenko [31]
Etaphase is a stage during the process of cell division (mitosis or meiosis). Usually, individual chromosomes cannot be observed in the cell nucleus. However, during metaphase of mitosis or meiosis the chromosomes condense and become distinguishable as they align in the center of the dividing cell.

A barometer measures the pressure of the atmosphere at different altitudes. Identify the location where the column of mercury is
Ghella [55]
The location where the mercury level of the barometer would be the lowest is at the very high altitudes of the Earth's atmosphere (about 100 km), since air pressure decreases as altitude increases.
