5. convection zone
6. 27 Million F
7. photosphere
8. 17 Million degrees
Answer is potassium: 19 protons, 19 electrons, 20 neutrons, mass of 39
The chemical activity series is the arrangement of the elements descendingly according to their chemical activity for reactions like simple substitution reactions and redox reactions. Elements above hydrogen can replace hydrogen from water and acids as they are more active than hydrogen. Since cesium is more active than hydrogen, it replaces it in hydrochloric acid.
2 cesium atoms loses 2 electrons first;
2Cs --> 2Cs+ + 2e-
2 hydrogen atoms recieve the two electrons;
2H+ + 2e- --> H2
The net ionic equation is;
2Cs + 2HCl --> CsCl + H2
Answer:
superposition hope this is what u are looking for?
Explanation:
Answer:
Covalent compounds use prefixes for naming because it specifies the number of atoms as more than one atom of each element is present.
Explanation:
Covalent compounds use prefixes for naming because it specifies the number of atoms as more than one atom of each element is present.
For example: "mono" indicates 1 atom, "di" indicates two atoms, "Hexa" indicates 6 atoms, "octa" indicates eight atoms.
When naming binary ionic compounds, the cation is named first, then the nonmetal anion is named.
