Which variables are given?
Answers
0.24 moles of oxygen must be placed in a 3.00 L container to exert a pressure of 2.00 atm at 25.0°C.
The variables given are Pressure, volume and temperature.
Explanation:
Given:
P = 2 atm
V = 3 litres
T = 25 degrees or 298.15 K by using the formula 25 + 273.17 = K
R = 0.082057 L atm/ mole K
n (number of moles) = ?
The equation used is of Ideal Gas law:
PV = nRT
n =
Putting the values given for oxygen gas in the Ideal gas equation, we get
n =
= 0.24
Thus, from the calculation using Ideal Gas law it is found that 0.24 moles of oxygen must be placed in a container.
Ideal gas law equation is used as it tells the relation between temperature, pressure and volume of the gas.

According to one acid-base theory, the H2O molecule
(1) accepts H+ ions (3) donate H+ ions
(2) accepts OH- ions (4) donates OH- ions
Answers
The statement, that describes acid-base theory in which the H2O molecule is "accepts ions."
What is an acid-base theory?
An acid is a compound that accepts a pair of electrons. A base is a generator of electron pairs. This is the broadest theory of acids and bases. Water can serve as both an acid and a base in solution, and it can also be both an acid and a base to itself. Water takes hydrogen ions and behaves as a base when coupled with an acid. When water is combined with a base, it gives hydrogen ions and so behaves as an acid. Using the balanced equation, the water molecule acts a acid which accepts the hydrogen ion. to form hydronium ion.
Hence the correct option is 1.

Answer:
Explanation:
The atomic number tell us the number of protons and neutrons in the nucleus of an atom. in other words ,each element has a unique number that identifies how many protons are in one atom of that element example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1.
