Through hypothesis and experiments
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.
A. Of a given element have different numbers of neutrons
The segment that represents melting is time (minutes) and temperature.
