Which 2 elements are gases at STP?
hydrogen, nitrogen, oxygen, fluorine, and chlorine are all gases at STP
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).
Is nitrogen a solid at stp?
No. Nitrogen is a gas in atmosphere, the air we breathe.
Does oxygen and nitrogen weigh the same in volume?
No, one mole of each, having the same VOLUME (about 22.4 L at STP), differ though in their masses: 32 g/mol for O2 and 28 g/mol for N2 So their densities (mass per volume) also differ in the same way: 1.43 g/L and 1.25 g/L respectively, at STP.
What volume of nitrogen at stp would be required to react with 0.100g of hydrogen?
To determine the volume of nitrogen needed to react with hydrogen, we need to know the balanced chemical equation. Once we have the balanced equation, we can use the stoichiometry of the reaction to calculate the volume of nitrogen. At STP (standard temperature and pressure), 1 mole of any gas occupies 22.4 L.
Why is hydrogen less dense than water?
At standard temperature and pressure (STP) hydrogen is a gas and water is a liquid.
Is nitrogen lighter than air?
If you are asking whether nitrogen is less dense than air and will float on top of it, then yes, nitrogen is "lighter," albeit only slightly. More accurately, nitrogen, which is a constituent gas of air, is less dense than air, not lighter. The density of air at standard temperature and pressure is 1.292 kg/m3. The density of nitrogen is 1.251 kg/m3.
Why is water less dense than frost?
Water is more dense than frost. Frost is ice, which is less dense than water. Siress: While this is true, frost can also be an agglomeration of ice particles in which large voids of trapped air can cause the density of the mass to be less than that of water. That's not a likely system to occur, or to exist for very long at STP with normal humidity, but hey...nits need to be picked.
Which 2 elements are gases at STP?
hydrogen, nitrogen, oxygen, fluorine, and chlorine are all gases at STP
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).
What is the speed of STP cable?
10 to 1000 Mbps for less than +/- 100m
Is nitrogen a solid at stp?
No. Nitrogen is a gas in atmosphere, the air we breathe.
What is more dense radon or water?
Radon is a gas, water is a liquid. Under the same conditions radon should be many hundreds of times less dense than water. Water's density at STP is about 1 000 kg/m3. Radon's density at STP is about 9.73g/m3. Thus, water is about 103 times denser than radon.
When an object or liquid's density is greater than one it wiLL BE WHAT?
The answer will depend on the units used. A density of 1 gram per litre is pretty light (less than the density of air at STP) whereas a density of 1 kilogram per ml is seriously dense.
What weighs less than air?
something that is lighter than the molecular mass of water.Mr of water= 2(1)+16=18therefore, anything with a Mr of lesser than 18 will be lighter than water vapour.example: hydrogen gas.Mr of hydrogen gas= 2(1)= 2therefore, it is lighter than water vapour.
Why does HE have a molar volume of 22.4dm3 at stp and ch3cl have a molar volume of 21.9dm3 at stp?
Because at STP, Chloroform is liquid and Helium is in gaseous state. When something is in a gaseous state, it occupies a larger space than the liquid. I thought however, that chloroform would occupy less than that
Which 5 L cylinder at STP will contain the greatest mass of gas particles nitrogen or neon?
Since gases occupy the same volume at STP regardless of their identity, a 5 L cylinder will contain the same number of gas particles for both nitrogen and neon. However, nitrogen is heavier than neon, so it will contain a greater mass of gas particles.
