Answer:
the ocean
Explanation:
because well the ocean despite how many trees we have make the mejorety of the air we breath even right now that is why the coast is so windy in the summer
First you need to solve for the number of moles in each.
1 mole of anything = atomic mas of that element (g)
Carbon has an atomic mass of 12.0107
1 mole of Carbon = 12.0107 g
Iron has an atomic mass of 55.845
1 mole of Iron = 55.845 g
now convert each from grams to moles
(grams of Carbon cancel and you are left with moles of carbon)
<u>100.0 g Carbon x 1 mol Carbon </u> = 8.326 mol Carbon
12.0107 g Carbon
(grams of Iron will cancel and you are left with moles of iron)
<u>100.0 g Iron x 1 mol Iron</u> = 1.791 mol Iron
55.845 g Iron
now we can use avogadro's number to solve for the amount of atoms in each
1 mol = 6.02x10^23 atoms
<u>8.326 mol Carbonx 6.02 x 10^23 atoms </u> = 5.012 x 10^24 atoms Carbon<u>
</u> 1 mol Carbon
<u>
</u><u>1.791 mol Iron x 6.02 x 10^23 atoms </u> = 1.078 x 10^24 atoms Iron<u>
</u> 1 mol Iron
<u>
</u>5.012 x 10^24 atoms Carbon > 1.078 x 10^24 atoms Iron
<u>
</u>
Answer:
If, for example, we want to know how many moles of oxygen will react with 17.6 mol ... Write the balanced chemical reaction for the combustion of C 5H 12
Explanation:
Aluminum does not undergo any phase change from 20.0°C to 100<span>.0°C, therefore we only consider sensible heat change, which is calculate as
</span>q = mc(dT)q = (12.5 g)(0.125 cal/g-°C)(100 - 20)<span>°C = 125 cal
</span>
Therefore, 125 calories of heat are absorbed by the aluminum.
conductor are defined as the materials or substances that allow electricity to flow through them. Also, conductors allow heat to be transmitted through them. Examples of conductors are metals, the human body, Earth and animals. The human body is a strong conductor.
Any material that keeps energy such as electricity, heat, or cold from easily transferring through is an insulator. Wood, plastic, rubber, and glass are good <em><u>insulator</u></em><em><u>.</u></em>
