Answer:
A charged atom is called an ion.Atom are neutral because they have the same numbers of positive and negative charges.By adding or taking away negative charges,Atom can become positive or negative.Protons and neutrons exist in the.nucleus of an atom.Protons have positive charge,whereas a neutron has no charge.
Explanation:
Data Given:
Pressure = P = 2.5 kPa = 0.02467 atm
Temperature = T = 157 °C + 273.15 = 430.15 K
Volume = V = ?
Mass = m = 10 g
First find out moles for given amount of Argon gas,
As,
Moles = Mass / M.mass
Putting values,
Moles = 10 g / 39.94 g/mol = 0.250 moles
Now using Ideal Gas Equation,
P V = n R T
Solving for V,
V = n R T / P
Putting Values,
V = (0.25 mol × 0.0821 L.atm.mol⁻¹.K⁻¹ × 430.15 K) ÷ 0.02467 atm
Volume = 357.87 L
An example of a dominant allele is brown eyes.
The correct answer should be: the molar amount of the gas.
