Answer:
I do experiment with salicylic acid
Explanation:
I I think you have to run and write the equation that you made in salicylic acid because salicylic acid is very harmful to us human have skin that is made up of Cleveland Clinic
Answer:
2.32 liters
Explanation:
you would just divide 24 by 3 which is 8 and multiply 290 by it which is 2320 and divide by 1000 which is 2.32
J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. ... Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus.
Answer:4
Explanation:
If we carefully observe the electronegativity of the elements in question
P-2.19
N-3.04
C-2.55
Si-1.9
H-2.2
SiH4 is definitely more polar than CH4 hence greater dipole forces of a higher boiling point. NH3 is more polar than PH3 hence NH3 has greater dipole forces and a higher boiling point. Electronegative differences influences the polarity of a bond. The greater the electro negativity difference between bonding atoms, the greater the dipole forces and the greater the boiling point.
