Answer:
Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup."
It's B the atom has 4 neutrons and 4 protons because atom can be completed through the existence of neutron and proton which stay inside of the neuclues of atom
The pH scale was given by Sorensen to quanitatively define strength of an acid and base
the pH scale extends from 0 to 14
For acids
The pH should be less than 7 [always]
For base
The pH should be more than 7 [always]
The pH seven is of neutral solution
pH = -log[H+]
Thus lower the pH higher the concentration of hydronium ion or protons produced by an acid
thus for the given pH scale interval [0-3] it represents strong acid [Which will give high concentration of protons on dissociation]
Maple syrup, which comes from the sap of maple trees, contains water and natural sugars. It's a clear, brown liquid and the sugars can’t be separated byfiltration. The category is insoluble.
