Copper(II) carbonate or cupric carbonate is a chemical compound with formula CuC\(O_3\)

Common name : Isobutyl bromide IUPAC name : 1-Bromo-2-methylpropane Boiling point : 102^\circC Formula : C\(_4\)H\(_9\)Br

Zymase is an enzyme complex that catalyzes the fermentation of sugar into ethanol and carbon dioxide. It occurs naturally in yeasts.

Propyne (methylacetylene) is an alkyne with the chemical formula HC\(\equiv\)CC\(H_3\)

It is primary alcohol because it has only one alkyl group and dihydric because it has two hydroxyl groups

A hydrocarbon is any of a class of organic chemicals made up of only the elements carbon (C) and hydrogen (H). Classes are Aliphatic and Aromatic Hydrocarbons. Natural sources are coal, natural gas and petroleum.

Since the surface tension forces become smaller as the distance between water molecules increases, the intervening soap molecules decrease the surface tension.

- Monosaccharides are reducing sugars. - Pure monosaccharides are water-soluble, white, crystaline solids. - They taste sweet - Form a black residue of carbon when dehydrated

Only 'mass' is a fundamental quantity

AT resonance; \(X_L\) = \(X_c\) \(\therefore\) = \(V_L\) = \(V_c\) = 40V

Given amount remaining = \(\frac{1}{64}\) = \(\frac{1}{64} = \frac{1}{(2)^{6}}\) \(\therefore\) = \(\frac{120 \text {years}}{6}\) = 20 years \(\Rightarrow\) T\(\frac{1}{2}\) = 20 years

Vernier calipers are also used to measure the internal and external diameters of a tube

- Acceleration, a = \(\frac{\text{v}}{\text{t}}\) = \(\frac{25}{20}\) = 1.25ms\(^{-2}\) - Force, F = ma = 800 x 1.25 = 1,000N - Average power = Force \times average velocity = 1000 \(\times \frac{0 + 25}{2}\) = 12,500W = 1.25 x 10\(^4\) W

Mass is a measure of how much matter is in an object.

Laminated iron core means insulating layers glued compact. Now the cores are laminated to reduce Eddy current.
