Hydrogen gas is given off when a reactive metal undergoes a single-displacement reaction with water is because the <span>very active metals react with water. For example, calcium reacts with water to form calcium hydroxide and hydrogen gas etc. </span>
Answer:
(A.) CO2, H2O
Explanation:
The chemical equation for respiration process is:
+
→
+
+ ATP↑
Energy is released during the biochemical process in the organism's cells in form of ATP. Byproducts of the reaction are carbon dioxide and water molecules.
Let me know if you require any further assistance.
Answer is the mass of the atom. Protons + neutrons= mass
Let's say you have oxygen with a mass of 16.
Oxygen has 8 protons
To find neutrons subtract 16-8= 8
So it would also be 8 neutrons.
Example of how to find mass if you know protons + neutrons:
Sodium has 11 protons and 12 neutrons. Add the protons and neutrons
11 + 12= 23
Mass is 23
