Which group 15 element exists as diatomic molecules at STP?
Nitrogen (N2) is the Group 15 element that exists as diatomic molecules at standard temperature and pressure (STP).
How many molecules of nitrogen filled chamber at STANDARD TEMPERATURE AND PRESSURE if the chamber is WIDTH x 300 litres?
At standard temperature and pressure (STP), one mole of any gas occupies approximately 22.4 liters. So, to calculate the number of molecules of nitrogen in the chamber, you would first need to convert the volume of the chamber from liters to moles, then use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules of nitrogen in the chamber.
How many nitrogen molecules are in 12 dm3 of nitrogen gas at room temperature?
There are approximately 1.35 x 10^24 nitrogen molecules in 12 dm^3 of nitrogen gas at room temperature, which is around 25°C. This calculation is based on Avogadro's Law, which states that at standard temperature and pressure (STP) one mole of any gas contains 6.022 x 10^23 molecules.
How nitrogen in liquid held together?
In liquid nitrogen, nitrogen molecules are held together by weak intermolecular forces known as van der Waals forces. These forces form due to the attraction between the partially positive and negative ends of the nitrogen molecules, resulting in a cohesive liquid state.
What happens to nitrogen liquid when heated?
When nitrogen liquid is heated, it will turn into gaseous nitrogen. As the temperature rises, the nitrogen molecules gain enough energy to break free from the liquid state and escape into the gaseous phase.
Which group 15 element exists as diatomic molecules at STP?
Nitrogen (N2) is the Group 15 element that exists as diatomic molecules at standard temperature and pressure (STP).
Equal volumes of nitrogen and oxygen at the same temperature and pressure would?
have the same number of molecules but different masses. This is because nitrogen and oxygen molecules have different molecular weights.
How many nitrogen molecules are in a balloon?
The number of nitrogen molecules in a balloon depends on the volume of the balloon and the pressure of the gas inside. However, at standard conditions (1 atm pressure, 0°C temperature), a balloon with a volume of 22.4 liters would contain 6.02 x 10^23 nitrogen molecules, which is known as Avogadro's number.
Nitrogen gas an example of a compound?
Nitrogen in any pure form is an element, not a compound. However, at standard temperature and pressure, nitrogen exists predominantly as divalent molecules.
How many atoms are found in 9 molecules of nitrogen gas?
At standard temperature and pressure, nitrogen contains two atoms per molecule. Therefore 9 molecules contain 18 atoms.
How many atoms of each element are there in one molecule of the nitrogen?
At standard temperature and pressure, nitrogen exists in molecules with two atoms each.
Why isn't Nitrogen very reactive cos?
Nitrogen is usually quite unreactive at both standard pressure and standard temperature. Nitrogen is relatively unreactive because nitrogen molecules are joined together by triple bonds, and these bonds are some of the strongest bonds that can exist between molecules.

Why pressure decrease with increase in humidity?
An increase in humidity causes the air to become less dense, which results in a decrease in pressure. This is because water vapor molecules displace nitrogen and oxygen molecules in the air, reducing the overall mass of air and lowering the pressure.
What mass of oxygen contain the same number of molecules as 42g of nitrogen?
Both nitrogen and oxygen exist at standard temperature and pressure as diatomic molecules. Therefore, the relative masses of equal numbers of molecules of the substance will the same as the ratios of their atomic masses, which are 15.9994 for oxygen and 14.0067 for nitrogen. The mass of oxygen that contains the same number of molecules as 42 g of nitrogen is 42(15.9994/14.0067) or 48 g, to the justified number of significant digits.
How nitrogen in liquid held together?
