The ratio of Boyle's temperature and critical temperature is 278. both a and b are present in Boyle's temperature.
What is boyles temperature ?Boyle temperature can be defined as the point in the temperature range in which a real gas starts to behave like an ideal gas at a pressure range.
The temperature at which the second coefficient in the expression becomes zero is also known as a Boyle temperature.
In Boyle's Temperature , TB=aRb.
Critical Temperature , TC=8a27Rb.
a and b are van der Waal's constants. R is molar gas constant. The Ratio of both temperatures
= TB/TC = aRb/8a27Rb
Both the critical temperature and boyles temperature have the Vander Waal's constant 'a' and 'b'.

In a double replacement reaction, why will two metals not combine with each other when products are formed
In a double replacement reaction, two metals will not combine with each other when products are formed because the metals form positive ions that do not attract.
The correct option is C.
What is a double replacement reaction?A double replacement reaction is a reaction in which there is an exchange of radicals between two compounds when a solution of the compounds is mixed together.
In a double replacement reaction, a precipitate is always formed when the two solutions of the compounds are mixed together.
During a double replacement reaction, the metallic ions exchange their negative radicals to form new compounds.
In accordance with the law of charges, similar charges do not attract each other, hence, the opposite ions of the metals and the negative radicals are attracted to each other.

A carbon atom has a relative atomic mass of
13.3. 60% of the carbon atom has a mass
number of 12.7, 30% of the carbon atom has a
mass number of 13.6, whilst the remaining 10%
has a mass number which is not known.
Calculate the mass number of the carbon isotope
which is 10% of the Carbon 13.3 atom.
Give your answer to 1 decimal place.
According to the claim, the carbon isotope that is 10% of something like the carbon 13.3 molecule has a mass number of 15.1.
Where can you find carbon?The majority of carbon is kept in reservoirs, or sources, such rocks and sediments; the remaining portion is kept in the atmosphere, the seas, and living things. Through the respiration of both and animals, carbon is returned to the atmosphere. Burning things like wood, oil, and gas also releases it.
Briefing:Since all carbon isotopes have an equal atomic mass of 13.3,
(0.60 * 13.3) + (0.3 * 12.7) + (0.1 * x) = 13.3
11.79 + 0.1x = 13.3
x = 15.1

Calculate the percent composition of H3PO4
The percent composition of hydrogen, phosphorous and oxygen in phosphoric acid is 3.06 %,31.60%,65.31 % respectively.
What is percent composition?Percent composition is defined as a convenient way to record concentration of solution.It is a expression which relates solute to solvent as,mass of solute/mass of solution ×100.There are two types of percentage composition percent weight by volume and percent volume by volume .
Percent composition of hydrogen=3/97.99×100=3.06%.
Percent composition of phosphorous=30.97/97.99×100=31.60%
Percent composition of oxygen=64/97.99×100=65.31%
