<h3>The enthalpy of combustion per mole of anthracene : 7064 kj/mol(- sign=exothermic)</h3><h3>Further explanation </h3>
The law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released
Q in = Q out
Heat can be calculated using the formula:
Q = mc∆T
Heat released by anthracene= Heat absorbed by water
Heat absorbed by water =
mol of anthracene (MW=178,23 g/mol)
The enthalpy of combustion per mole of anthracene :
<span>The energy associated with the 590nm atomic emission line is 3.369 x 10^49 Joules. This can be determined by multiplying Plank’s constant (6.626 x 10^34 Js) by the speed of light (3x 10^8 m/s), and then dividing the result by the wavelength (590 x 10^-9 m).</span>
The gravimetric factor for Ag2O in AgS is 0.1078
<u>Explanation:</u>
<u>Solving the problem:</u>
<u>we need the atomic mass of the given data</u>
- <u>Atomic mass of </u>Ag2O = 231.735 g/mol
- Atomic mass of AgS= 28 g/mol
<u>Then add the atomic mass,</u>
Addition=231.735+28
Addition=259.735
Then divide AgS by Ag2O (addition value)
<u>Then division= 28/259.735</u>
Division=0.1078
<u>The gravimetric factor for Ag2O in AgS is 0.1078</u>

A practical pursuit of alchemy was the development of metallurgy practices. As alchemists always tried to turn various metals into other things, metalworking techniques were developed even though their experiments were often unsuccessful.

Answer:
It is traveling at 170 miles per hour.
Explanation:
divide 340 by 2 because right now it's at 340 miles per two hours.
You get 170 miles per hour.
