Explanation:
Answer:
Mass = 2.222 g
Explanation:
Given data:
Volume of neon gas = 2.56 L
Temperature = 273 K
Pressure = 1 atm
Mass of neon gas = ?
Solution:
PV = nRT
n = PV / RT
n = 1 atm × 2.56 L/ 0.0821 atm. L / mol. K× 273 K
n = 2.56 L.atm / 22.4 atm. L/ mol
n = 0.11 mol
Mass = number of moles × molar mass
Mass = 0.11 mol × 20.2 g/mol
Mass = 2.222 g
Answer Electromagnetic waves are used to transmit long/short/FM wavelength radio waves, and TV/telephone/wireless signals or energies. They are also responsible for transmitting energy in the form of microwaves, infrared radiation (IR), visible light (VIS), ultraviolet light (UV), X-rays, and gamma rays.
Explanation:
The type of relationship exists between reactant concentration and reaction rate is direct relationship. The type of relationship exists between reaction temperature and reaction time is inverse relationship.
According to the collision theory, the more particles colliding, having the activation energy, the higher the rate of reaction. This implies that if we increase the concentration of colliding particles, the rate of reaction increases accordingly. This is a direct relationship.
We know that for every 10°C rise in temperature, the rate of reaction doubles. This means that there is an inverse relationship exists between temperature and reaction time because higher temperature means shorter reaction time and vice versa.
The more the kinetic energy of the reaction the higher the reaction rate because the particles collide more frequently. This is a direct relationship.
