Hey mate
SORTING METHOD can easily be used to separate a mixture of steel ball bearing and marbles. This separation method is suitable because the two substances that are mixed together have big sizes, so it is easy to separate the two by hand picking the particles. Sorting method is usually used as a separation technique when the size of the mixture is big and the mixed substances are in the same state.
Hope it help ya
A) probably some thin metal would work
B) Medium strength
C) either an electron or positron
D) 9.11x10^-31 kg
Answer : The pH of a solution is, 7.28
Solution : Given,
Concentration of hydronium ion, =
pH : It is defined as the negative logarithm of hydronium ion concentration or hydrogen ion concentration.
Now put the value of hydronium ion concentration in this expression, we get the pH of the solution.
Therefore, the pH of a solution is, 7.28
Answer:
1.Molecules are made of atoms. So different molecules can have different (or same) number of atoms they are made of.Different atoms are made of different number of protons of neutrons in the nucleus (also electrons around the nucleus but they are very small even compared to atom and don’t add up for volume or mass) therefore their radius and mass are different.
2.Chromatography works because of differences in the properties of molecules in materials.some molecules differ in shape and size. These differences in molecular properties allow scientists to separate compounds into individual molecules using chromatography.
