Answer:
D im pretty sure cuz i prob had this test already
Explanation:
NaOH (s) is in solid state and NaOH (aq) is an aqueous solution.
Answer:
CaCO3+2HCl=CaCl2+H2O+CO2 this is the balanced reaction occur between calcium carbonate and HCl to minimize the hyperacidity.
Explanation:
CaCO3 reacts with hydrochloric acid produced by oxytonic cells of the stomach to generate calcium chloride (CaCl2) and water(H2O) along with the release of carbon dioxide(CO2) gas.
This reaction helps to minimize hyperacidity.
The answer is NO
N has 5 valence electrons
O has 6
Therefore combined there is 11 electrons so they will never complete the octet
