To answer this, we look at the polarities of these molecules given. A molecule is said to be polar when there is an unequal shraing of electrons the opposite is called nonpolar.
CH4 = nonpolar
CH3OH = polar
CH3 CH3 = nonpolar
CH3 CH2 CH2 OH = polar
<span>CH3 CH2 CH2 CH2 CH2 CH3 = nonpolar</span>
Answer:
This is required answer.
Explanation:
Given that,
Thermal energy chemical change lab report
We know that,
Thermal energy :
When we rise a temperature of any substance then the molecules of substance moves fastly then the heat produced. It is called thermal energy.
Chemical change in the thermal energy :
When we heat a substance then the thermal energy increases and the molecules of substance moves fastly. That means the chemical bonds are break in reactants due to energy.
In products, The new chemical bonds are create due to energy.
For example ; The coal is burned then produced heats water and change it into steam.
Hence, This is required answer.
Answer:
HCl conc.= 6.0mol/L
Explanation:
From the dissociation of HCl= 1 mole H+ and 1mol Cl-, which is equivalent stoichiometrically in concentration to that of 1 mol HCl,
