Answer:
Explanation:
The limiting reactant (or limiting reagent) is the reactant that gets consumed first in a chemical reaction and therefore limits how much product can be formed.
Answer:
False
Explanation:
It is not correct to assert that a chemical change has occurred if the number of atoms is greater after the reaction than it was before the reaction.
For every chemical reaction, the law of conservation of mass must be strictly adhered.
The law states that "during a chemical reaction, matter is neither created nor destroyed, atoms are simply rearranged".
By the virtue of this law, the number of atoms at the beginning and the end of the reaction must remain the same for this law to be applicable.
Answer:
the spiral type of galaxy
Question:
The options are;
a. Temperature
b. Thermal Energy
c. Hotness
d. Fire Energy
Answer:
The correct option is;
b. Thermal energy
Explanation:
A burner on a stove produces thermal energy which is used to raise the temperature of the metal container (kettle, pot or pans) in which items are placed for heating.
Thermal energy is the internal energy of the system given off as heat which when transferred from one body to another causes the temperature of the receiving body to rise. Thermal energy in a burner is given off when the gaseous fuel reacts or burns in the presence of or with oxygen to produce carbon dioxide and water vapor in an exothermic reaction.
4C + 5H₂ + 13/2O₂ (-125 kJ) → C₄H₁₀ + O₂ → CO₂ + H₂O (-2877 kJ).
