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).
Hydrogen gas is produced when dilute hydrochloric acid is added to a reactive metal.
Balanced molecular equation of sodim metal with hydrochloric acid:
2Na(s) + 2HCl(aq) → 2NaCl(aq) + H₂(g).
Ionic equation: 2Na(s) + 2H⁺(aq) + 2Cl⁻(aq) → 2Na⁺ + 2Cl⁻(aq) + H₂(g).
Net ionic equation: 2Na(s) + 2H⁺(aq) → 2Na⁺(aq) + H₂(g).
Sodium is oxidized from oxidation number 0 (Na) to oxidation number +1, hydrogen is reduced from oxidation number +1 to oxidation number 0 (hydrogen gas H₂).
Another example:
Balanced chemical equation: Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g)
Word equation: zinc + hydrochloric acid → zinc chloride + hydrogen gas

I assume about 5 atoms are in one molecule of this product
Answer:
Explanation if an object is in motion and more force is applied to it, the object will begin moving faster. If two objects have the same mass and a greater force is applied to one of the objects, the object which receives the greater force will change speeds more quickly.:
Answer:
Formic acid, citric acid, Oxalic acid, washing soda, baking soda, etc. can be some examples of natural acids and natural bases. They both have domestic, industrial, and various other purposes.
Explanation:
<h3><u>
NATURAL ACIDS</u>
:</h3>
There are lots of natural acids present in our nature. Some of them are the following:
> <u>Formic acid</u>
USE: It is used in the stimulation of oil and gas wells as it is less reactive towards the metal.
> <u>Citric acid</u>
USE: It is considered as the best rust remover as it doesn't harm the metal just remove the rust.
> <u>Oxalic acid</u>
USE: It easily remove iron and ink stains and that's why it is used as an acid rinsing material in Laundries.
<h3><u>
NATURAL BASES</u>
:</h3>
There is a variety of natural base found in our nature which founds a lot of uses in day to day life. some of them are the following:
> <u>Washing soda</u>
USE: It is used in commercial detergent mixture to treat hard water.
> <u>Baking soda</u>
USE: It is the best rising agent used mostly in cooking and for domestic purposes like removing stains, etc..
