They all contain acid and bases
Yes, all alkalis contain oxygen and hydrogen.
Yes all alkalis have an OH- group, however this is not true for bases.
Oven cleaner does contain alkalis
No, many alkalis (bases) do not. These include potassium carbonate (Na2CO3), sodium hypochlorite (NaClO), and calcium oxide (CaO).
1. An alkali must contain a metal ion 2. Alkali sometimes can neutralize acid, if it is applied with enough force 3. All alkalis are inedible 4. For an alkali to be found in nature, it must not contain radioactivity 5. Uses of alkalis include tanning leather, cleaning, and scrubbing

No- hydrochloric acid is an acid and is the opposite of an alkali so no alkalis contain it

Most toothpastes contain alkalis , however some can contain acids.
No, many alkalis (bases) do not. These include potassium carbonate (Na2CO3), sodium hypochlorite (NaClO), and calcium oxide (CaO).
All acids contain H+ but stronger acids contain more than weaker acids. Alkalis contain OH-. In stronger alkalis there is more OH- and in weaker, there is less. This is why pH7 is neutral - the H+ and the OH- form H2O which is a neutral substance.

None. Calcium is an element. Acids contain H+ ions, eg, sodium chloride. (NaCl2) Alkalis contain OH- ions, eg, sodium hydroxide. (NaOH)
All alkalis are soluble in water.
All living sources contain the element Carbon
Potassium is an element. Alkalis are compounds, so no it is not an alkali.
