Convert particles to moles then moles to grams
Answer:0.0922 Fahrenheit per minute
Explanation: Temperature change in degree Fahrenheit from Celsius is given by multiplying the change in temperature in celsius by 1.8 and adding 32 to it. Now the temperature you added is in Fahrenheit. But the temperature change is for a day. To convert change in temperature per day to per minute divide the obtained answer in Fahrenheit by 24*60.
Thus,
change in temperature in Fahrenheit: (56*1.8)+32= 132.8 degree Fahrenheit
change in temperature per minute: (132.8)/(24*60)= 0.0922 degree Fahrenheit per minute
To answer this item, it is assumed that O2 is an ideal gas such that it follows the ideal gas law.
PV = nRT
Solving for n,
n = PV / RT
where n is number of moles, P is pressure, V is volume, R is the universal gas constant, T is the temperature.
Substituting the known values,
n = (724 mmHg/760 mmHg/1 atm)(1 L) / (0.0821 L. atm/mol.K)(298 K)
Simplifying,
n = 0.0389
Hence, the value of n is 0.0389.
Below are the three possible isomers of chemical formula C₂H₂Cl₂. Among these three isomers the <em>trans</em>-1,2-dichloroethene is non-polar while, remaining two are polar.
Reason:
Reason for this is dipole moment. In case of <em>cis</em>-1,2-dichloroethene and 1,1-dichloroethene, the vectors are reinforcing each other perpendicularly to double bond, hence, giving a net dipole moment and making these two isomers polar in nature.
While, in case of <em>trans</em> isomer the two vectors are cancelling each other as the two chlorine atoms are in opposite directions. Hence, the net dipole moment is zero in this case. So, it is non-polar in nature.
