2. They all have 1 valence electron, they form ions with a +1 charge.
3. cation
4. Lithium, Li
5. Francium, Fr
6. Cesium has a melting point of 28.5 C so I’m assuming that’s the correct answer, Francium is radioactive
7. Sodium, Rubidium, Lithium, and Cesium are all soft metals that can be cut with a knife.
8. Oxygen
9. Hydrogen gas
10. Bases
Answer:
C. CrF6, chromium(VI) hexafluoride.
Explanation:
Hello,
In this case, since we are given a hexavalent chromium we must notice it has +6 as its oxidation state. Moreover, fluorine, when forming ionic compounds works with -1, for which the chemical formula is:
And the stock name is indeed C. CrF6, chromium(VI) hexafluoride (looks like D. is the same) since we have six fluoride ions in the formula and we point out chrmium's oxidation state.
Regards.
Answer:
Use less heat in your house.
Explanation:
You have blankets in your house, huddle up for a good movie together.
Ten protons would be Neon, but the most stable? I'd have to say 12 neutrons in contrast to the 10 protons. Not too negative in balance.
The cathode electrode is copper. This means that the concentration of copper must be increased to increase the cell potential. This can be done by diluting the Al3+ solution. Increasing the surface area will not change the current but will increase the voltage. The answer is (D) I and III only.
