Answer:
b) Baking soda
Explanation:
Baking soda is sodium hydrogen carbonate, NaHCO₃.
It reacts with water according to the equation
NaHCO₃ + H₂O ⇌ H₂CO₃ + NaOH
Thus, baking soda is a base because it increases the concentration of hydroxide ions in water.
<em>Water</em> is <em>neutral</em>.
<em>Lemon juice</em> is an <em>acid</em> because it contains citric acid.
An <em>insulator </em>is a substance that does not conduct electricity. Insulators are <em>neither acidic nor basic</em>.
Bronsted Lowry base is the species that accepts or acquires protons from other species of the reaction. is the Bronsted-Lowry base.
<h3>What is a Bronsted-Lowry base?</h3>
In an acid-base reaction, the element or the compound capable of obtaining a proton or a hydrogen atom is called a Bronsted-Lowry base.
According to the theory, the base will accept proton and acid will donate an electron. The reaction of the acid and base is shown as,
From the reaction, it can be said that bicarbonate is the Bronsted-Lowry base as the number of hydrogen or protons are increasing in the product.
Therefore, option b. is the Bronsted-Lowry base.

Answer:
d
Explanation:
Isomers are molecules that have the same molecular formula(the same number of each atom), but different structural formulas
in this case both have the formula C2H5O
Answer:
The period number tells which is the highest energy level occupied by the electrons.
Explanation:
- The period number (denoted by n) is the outer energy level that is occupied by electrons in an atom.
- The period number that an element is in, is the number of energy levels that the element has.
- When we move across a period from left to right in a periodic table the number of electrons in atoms increases within the same orbit.
