Answer:
The final temperature of water = 22.1224 °C
Explanation:
<u>Step 1</u> : defien the formula for heat transfer
q = m*c*ΔT
with q = heat transfer
with m = mass of the substance
with c = specific heat ( of water in this case)
with ΔT = difference between final temperature and initial temperature
In this case :
q=366kJ = 366 *10^3 J
mass of water = 48kg = 48000g
c= specific heat of wwater = 4.184 J / g °C
initial temperature = 20.3 °C
final temperature = TO BE DETERMINED
<u>Step 2</u>: Calculate temperature
366000 J = 48000g * 4.184J/g °C * (T2 - 20.3)
366000 / (480000 * 4.184) = 1.8224 = (T2 - 20.3)
T2 = 20.3 + 1.82 =22.1224 ° C
The final temperature of water = 22.1224 °C
Answer:
air is not a mixture because of scientists freezing it and finding different liquids, it is a mixture because the compounds that make up air e.g. oxygen (o2), Carbon dioxide (co2) and the most important Nitrogen which is an element and makes up 78.09% of air are not chemically bound in the way that compounds are
Explanation:
The m/z and relative abundance of the ions contributed to the peak at 21.876 min. The relative abundance will be 21.876%.
<h3>
What is relative abundance?</h3>
- The proportion of atoms with a particular atomic mass present in an element sample taken from a naturally occurring sample is known as the relative abundance of an isotope.
- When the relative abundances of an element's isotopes are multiplied by their atomic masses and the results are added up, the result is the element's average atomic mass, which is a weighted average.
- Chemists often divide the number of atoms in a particular isotope by the sum of the atoms in all the isotopes of that element, then multiply the result by 100 to determine the percent abundance of each isotope in a sample of that element.
