Answer:
The ionization energy of each successive element generally decreases
Explanation:
The ionization energy increases in the periods of the periodic table and decreases in the groups. If the atom is very small, we will need a lot of energy to release the electron, while if the atom is larger the energy will be greater.
Answer:
See explanation
Explanation:
Calcium carbide reacts with water to yield acetylene gas and calcium hydroxide as follows;
CaC2(s)+2H2O(g)⇋Ca(OH)2(s)+C2H2(g)
This now shows us that the equation as written in the question is wrong. Since the equation for the reaction of calcium carbide and water as shown in the question is wrong, the equation can not be balanced.
Answer:
covalent bond
Explanation:
ionic bond is when electrons are transferred by atoms not shared
3Ca(OH)₂ (aq) + 2H₃PO₄ (aq) -> Ca₃(PO₄)₂ (s) + 6H₂O (l)
