The sub-atomic particles are not made up of atoms, they have their own identity.
What are sub-atomic particles?Sub -atomic particles are defined as particles which compose an atom. A sub -atomic particle can be a composite particle composed of other particles or an elementary particle which is not composed of other particles.
The elementary particles are six flavors of quarks , six types of leptons and twelve gauge Bosons .All sub atomic particles have an electric charge which is an integer multiple of elementary charge.They are in smaller in size as compared to atoms.
The three fundamental sub-atomic particles are electrons , protons and neutrons . The smallest known sub-atomic particles to exist are called quarks. Neutrons and protons are the sub-atomic particles which reside in the nucleus and are together called as nucleons.

how an ionic compound made up of charged particles can be electrically neutral
Answer:
Explanation:
Ionic compounds are electrically neutral because the charges of the cations and anions that make up the compound cancel each other out. In the case of salt for example, sodium has a charge of positive one, and chloride has a charge of negative one. Together, they neutralize the compound.

What is the mass of CO2 lost at 20 min from the limestone sample?
How much CO2, in moles, was lost at 20 min from the limestone sample?
How much CO3 2- was lost at 20 min from the limestone sample?
Answer:
The mass, CO2 and CO3 from the limestone sample is discussed below in details.
Explanation:
(A) mass loss of sample of limestone after 20 min
= 0.8437g-0.5979g = 0.2458 g
From the given reaction of limestone, 2 mol of the sample gives 2 moles of CO 2.
Therefore
184.4 g ( molar mass of limestone) gives2× 44 g of carbon dioxide.
1 g of sample gives 88/184.4 g of carbon dioxide
Hence 0.2458 g sample gives
= 88/184.4 × 0.2458 g = 0.117 g carbon dioxide
(B) mole of CO 2 lost = weight/ molar mass
= 0.117 g / 44 g/mol =0.0027 mole
(C). 1 mol of limestone contain 2 mol of carbonate ion
From the reaction we know that carbonate ion of limestone is converted into carbondioxide
Hence lost carbonate ion = 0.2458 g
(D) we know that
1 mol limestone contain 1mol CaCO 3
Hence in sample present CaCO 3
= 1mole / 184.4 g × 0.8437 g= 0.00458 mol CaCO3

What is represented in each block of the periodic tables?
the answer is c
it wants me to write a 20 letter explanation but ion got time for that
One ion is represented in each block of the periodic tables. Hence option C is correct.
What is periodic table?Periodic table is defined as a table with the chemical elements ordered by increasing atomic number, displaying the elements to show trends in their characteristics. The elements are arranged in the Periodic Table in accordance with their related chemical and physical characteristics. There are rows and columns in the table. The periodic table's vertical columns stand in for Groups. Periods are shown in the table as horizontal rows.
Ions are defined as any atom or collection of atoms that carries one or more electrical charges, either positive or negative. The positive ions are known as cation while the negative ions are known as anion. When an atom's number of protons and electrons is out of balance, ions are created.
Thus, one ion is represented in each block of the periodic tables. Hence option C is correct.

Green plants use light from the Sun to drive photosynthesis. Photosynthesis is a chemical reaction in which water H2O and carbon dioxide CO2 chemically react to form the simple sugar glucose C6H12O6 and oxygen gas O2.
What mass of water is consumed by the reaction of 6.49g of carbon dioxide?
ANSWER:
2.65 g H2O
Explanation:
6.49g (co2) / 44.009g (co2) x 1 mol (co2) / 1 mol (h2o) x 1 mol (h2o)
=0.147 mol H2O
0.147 mol (H2O) / 1 mol (h2o) x 18.015 g (h2o)
=2.65 g H2O

Which diagram best shows the field lines around two particles with opposite

The diagram best shows the field lines around two particles with opposite charges is the third diagram. Therefore, option C is correct.
What is field line ?A graphic tool for viewing vector fields is a field line. It is made up of a fictitious directed line that is perpendicular to the field vector over its whole length.
Among many other sorts, they are employed to display magnetic, electric, and gravitational fields. In the study of fluid mechanics, streamlines are field lines that display the velocity field of a fluid flow.
The field lines are parallel to the charge's surface. Both the size of the charge and the quantity of field lines are proportional. The positive charge is where the field lines begin, and the negative charge is where they come to a conclusion.
Thus, option C is correct.

What are the signs of ΔH, ΔS, and ΔG for the spontaneous conversion of a crystalline solid into a gas?
Answer:
ΔH>0, ΔS>0, and ΔG<0
Explanation:
Crystalline solid → Gas
ΔG < 0 T as the reaction is Spontaneous The solid is converted into gas so the Entropy will increase as randomness is more in gas than solid, ΔS > 0using Gibbs equation
ΔG = ΔH - TΔS
as ΔG < 0 and ΔS > 0
ΔH - TΔS <0
ΔH < TΔS ⇒ΔH >0
This gives that ΔH will be Positive but it will be less than TΔS. So we need to provide some energy to convert crystalline solid into gas.
