Answer: The correct answer is Option 2.
Explanation:
Organic compounds are defined as those compounds in which a covalent bond is present between hydrogen and carbon atom. They are basically known as hydrocarbons. If any atom other than hydrogen and carbon is present, it is not considered as an organic compound.
From the given options:
Option 1:
A, calcium atom is present, so it is not considered as an organic compound.
Option 2:
As., only carbon and hydrogen atom is only present, so it is considered as an organic compound.
Option 3:
As, oxygen atom is present, so it is not considered as an organic compound.
Option 4:
As, phosphorous and oxygen atoms are present, so it is not considered as an organic compound.
From the above information, the correct answer is Option 2.
The formula (2) represents an organic compound.
What is an Organic compound
Organic compounds are compounds that primarily consist of carbon (C) and hydrogen (H), along with other elements such as oxygen, nitrogen, sulfur, and others. The formula represents an organic compound that contains four carbon atoms (C₄) and eight hydrogen atoms (H₈).
These examples represent a small fraction of the vast array of organic compounds found in nature and synthesized in laboratories.
Hence we can say that option 2 is right. represents an organic compound.

Laundry detergent is not liquid starch as they have different chemical composition due to presence of different compounds with different properties.
Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are joined by ionic bond.
3)Inter-metallic compounds where atoms are held by metallic bonds
4) co-ordination complexes where atoms are held by co-ordinate bonds.
As laundry detergent and liquid starch have different chemical compositions and detergent does not hardens the clothes while starch does.Thus, laundry detergent is not liquid starch .

Keep in mind that not all detergents contain liquid starch, but many do.

Answer:
Radius of the steel ball is 4.6mm
Explanation:
Hello,
To find the radius of the steel, we'll have to calculate it from it's volume which can be gotten from the density of the material.
Data;
Mass = 3.25g
Density = 7.86g/cm³
Density = mass / volume
Volume = mass / density
Volume = 3.25 / 7.86
Volume = 0.413cm³
Volume of a steel = 4/3πr³
0.413 = 4/3 × π × r³
0.413 = 1.33 × 3.14 × r³
0.413 = 4.1762r³
r³ = 0.413 / 4.1762
r³ = 0.099
Take the cube root of both sides
r = 3√(0.099)
r = 0.46cm
From metrics table
1cm = 10mm
0.46cm = x mm
x = (0.46 × 10)
x = 4.6mm
The radius of the steel ball is 4.6mm
