What is nitrogen's standard state?
The state of nitrogen is gas at 298 K. Nitrogen's symbol is N and it;s atomic number is 7.
What is the volume of 72.0 grams of sulfur dioxide?
To find the volume of a gas such as sulfur dioxide with a given mass, you need to know the temperature, pressure, and molar mass. Assuming standard temperature and pressure conditions (STP), the volume of 72.0 grams of sulfur dioxide can be calculated using the ideal gas law equation (PV = nRT), where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
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.
Why relative lowering of vapour pressure is independent of temperature?
Relative lowering of vapour pressure is function of pressure of pure liquid and pressure of solutions when you increase temperature both the values increase and compensate the increase value, According to the Raoult's law, Psolvent = Xsolvent Po where Psolvent is the vapour pressure of the liquid solution, Xsolvent is its mole fraction in the solution and Po is the pure vapour pressure.
Describe the relationship between temperature and pressure?
The relationship between temperature and pressure is not named after a specific person, like Boyle's or Charles' Laws, but states that the relationship between the temperature and pressure of a gas (usually as observed in a rigid container) is direct. Therefore, as temperature increases, pressure does too.This is Gay-Lussac's law.The temperature and pressure of gasses are related. As the pressure increases the temperature also increases, and vice verse. As the pressure decreases the temperature gets colder.The ideal-gas law may be expressed as PV=nRT.Absolute temperature TNumber of moles (a measure of the number of molecules) nVolume VPressure PRydberg's constant R (some value that makes the numbers and the units work)Obviously, from the equation, you could half the temperature and keep the pressure the same, if, for example, you cut the volume in half. Or you could half the temperature and double the number of moles, and the pressure wouldn't change.
What is the total number of elements in group 17 that are gases at room temperature and standard pressure?

What is the total number of elements in the ''properties of six elements at standard pressure'' table that are solids at stp?
Standard temperature is 0 degrees Celsius so you are looking for the elements that have a melting point above 0 degrees Celsius. The answer is 4 elements. Elements E, G, L, and Q.
What is the total number of elements in Group 17 that are gases at room temperature at standard pressure?
There are five elements in Group 17 (also known as the halogens) that are gases at room temperature at standard pressure: fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2), and astatine (At2).
What are chlorine?
Chlorine is a member of the Halogen group of elements. Under standard conditions of temperature and pressure Chlorine is a highly reactive yellowish green gas. It is a di-atomic element, number 17 in the periodic system: Cl2
How are elements indentified on the periodic table?
Elements in the table are identified by different things. What they are made of, atomic mass, and atomic number. Elements can also be identified by what state of matter they are at zero degrees Celsius and standard pressure which 1atm. The most current, standard table has 117 different elements.
How do you calculate the volume of natural gas in standard cubic meter at standard pressure?
To calculate the volume of natural gas in standard cubic meter at standard pressure, you can use the ideal gas law equation: V = nRT/P, where V is the volume in standard cubic meters, n is the number of moles of gas, R is the ideal gas constant, T is the temperature in Kelvin, and P is the standard pressure. Given that standard pressure is typically defined as 1 atmosphere or 101.325 kPa, you can plug in these values along with the temperature and number of moles of gas to calculate the volume of natural gas in standard cubic meter at standard pressure.
How much space will 2.3 grams of sulfur dioxide take up at standard temperature and pressure?
we first find the number of moles( number of moles= mass/molar mass). the we can find the volume by using the formule( volume=number of moles multiplyd by the molar volume)
How many mole of argon gas will fill a volume of 116.7 L?
To determine the number of moles of argon gas required to fill a volume of 116.7 L, we first need to convert the volume to liters. Using the ideal gas law equation, PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature, we can calculate the number of moles. Given that argon gas is at STP (standard temperature and pressure), we can use the standard values of 1 atm for pressure and 273 K for temperature.
What is neons physical state at stp?
