<u>Answer:</u>
<em>49822 joules of heat can be transferred to ankle from heat bag.
</em>
<u>Explanation:</u>
We know that average body temperature should be <em>37 degree centigrade
</em>
Hot water bag has 715 grams of water present in it. Specific heat of 1 gram of water is 4.18 joules per gram per degree centigrade. 715 grams will have ![715 \times 4.18= 2988.7 j](https://tex.z-dn.net/?f=715%20%5Ctimes%204.18%3D%202988.7%20j)
The degree of water that is given is 60° hence specific heat becomes![179322 \ j](https://tex.z-dn.net/?f=179322%20%5C%20j)
<em>Specific heat of body at 37° centigrade will be =
</em>
<em>The amount of heat that can be transferred from hot bag will be
</em>
Answer:
The independent variable would be the type of sunscreen. Hope this helps! :)
This is a one-step unit analysis problem. Since we are staying in moles, grams of our compound, and thus molar mass, is not needed.
1 mole is equal to 6.022x10²³ particles as given, so:
![1.5x10^{24} particles FeO_{2} (\frac{1mol}{6.022x10^{23}particles } )=2.49 molFeO_{2}](https://tex.z-dn.net/?f=1.5x10%5E%7B24%7D%20particles%20FeO_%7B2%7D%20%28%5Cfrac%7B1mol%7D%7B6.022x10%5E%7B23%7Dparticles%20%7D%20%29%3D2.49%20molFeO_%7B2%7D)
<h3>
Answer:</h3>
2.49 mol
Let me know if you have any questions.
Molar mass is 56.02 grams
Explanation:
George Washington Carver was born enslaved and went on to become one of the most prominent scientists and inventors of his time, as well as a teacher at the Tuskegee Institute. Carver devised over 100 products using one major crop — the peanut — including dyes, plastics and gasoline.
