If it is 60 Celsius that would conver to fare height by means of this equation; (1.8*60)+32°F
Which would come out to.... 140° Fahrenheit... Hardly seems like chilly conditions.
Answer:
Diatomic molecules are molecules composed of only two atoms, of the same or different chemical elements. The prefix di- is of Greek origin, meaning "two
Explanation:
Answer:
C₆H₆O
Explanation:
The given values are the percentage in mass of each element. Empirical formula is the simplest ratio of atoms presents in a molecule. Thus, the first we need to do is convert this percentage to mass using molar mass of each element:
<em>Moles C:</em>
76.57C * (1mol / 12g) = 6.38 moles C
<em>Moles H:</em>
6.43 * (1mol / 1g) = 6.43 moles H
<em>Moles O:</em>
17.0% * (1mol / 16g) = 1.06 moles O
Dividing each number of moles in the moles of O (The minimum number of moles. Used to obtain "The simplest ratio..."):
C = 6.38 moles C / 1.06 moles O = 6
H = 6.43 moles H / 1.06 moles O = 6
O = 1.06 moles O / 1.06 moles O = 1
That means empirical formula of phenol is:
<h3>C₆H₆O</h3>
Explanation:
Mass (m)=0.3 kg
height(h)=2.6 m
acceleration due to gravity (g)=10m/s^2
Potential energy= MGH
=0.3×10×2.6
7.8 J
