The practice tests provide a realistic simulation of the actual exam, allowing you to become familiar with the format, style, and types of questions you will encounter on the actual test. Certification exams don't just measure what you know -- they are also a test of how well you perform under pressure. The right type of test preparation helps you familiarize yourself not only with the material you're being tested on, but also the format of the test, so you feel less anxiety on test day.

Praxis General Science - General Exam Info Sample Questions

What will be the effect on pressure when Helium gas at 300 K is shifted from a vessel of 250 cm3 to a vessel of 1L capacity?





Correct Answer:
decrease to 1/4th of the original value


the question provided is about the change in pressure when helium gas is transferred from a smaller vessel (250 cm³) to a larger vessel (1 liter, i.e., 1000 cm³) while maintaining a constant temperature (300 k). to solve this, we can apply boyle’s law, which is a fundamental principle in chemistry and physics that describes the inverse relationship between the pressure and volume of a gas at constant temperature.

boyle's law states that the product of the pressure and volume of a fixed amount of an ideal gas, kept at a constant temperature, is constant. mathematically, it is expressed as: \[ p_1v_1 = p_2v_2 \] where: - \(p_1\) and \(v_1\) are the initial pressure and volume of the gas, - \(p_2\) and \(v_2\) are the final pressure and volume of the gas.

in this scenario: - the initial volume \(v_1\) is 250 cm³. - the final volume \(v_2\) is 1000 cm³. - we need to find the final pressure \(p_2\) given that the initial pressure \(p_1\) is unknown but constant.

substituting the known values into boyle’s law formula, we get: \[ p_1 \times 250 = p_2 \times 1000 \] to isolate \(p_2\), we rearrange the equation: \[ p_2 = \frac{p_1 \times 250}{1000} \] \[ p_2 = \frac{p_1}{4} \]

this calculation shows that the final pressure \(p_2\) is one fourth of the initial pressure \(p_1\). therefore, when the helium gas is moved from a smaller vessel to a vessel with four times greater capacity, the pressure decreases to one fourth of its original value. this outcome is a direct consequence of boyle’s law, illustrating how pressure decreases as volume increases when temperature is kept constant. this is why the correct answer to the question is that the pressure will "decrease to 1/4th of the original value".

In a water molecule how many H-bonds are formed, how many water molecules are attracted to each water molecule, and how are the H-bonds formed?





Correct Answer:
4, 4 and tetrahedral


the structure and properties of water molecules are profoundly influenced by hydrogen bonds. in a water molecule (h2o), the oxygen atom is bonded to two hydrogen atoms covalently, forming a bent molecular shape due to the electron pair geometry. this shape and the difference in electronegativities between hydrogen and oxygen create partial positive charges on hydrogen and a partial negative charge on oxygen, making water a polar molecule.

hydrogen bonding occurs in water due to this polarity. each hydrogen atom in a water molecule, bearing a partial positive charge, can attract the partially negative oxygen atom of another water molecule. conversely, the lone pairs of electrons on the oxygen atom of a water molecule can attract hydrogen atoms from other water molecules. thus, each water molecule can form up to four hydrogen bonds: two through its hydrogen atoms (donors) and two through its lone pairs on the oxygen atom (acceptors).

in an ideal situation, where each water molecule is surrounded symmetrically by others, a tetrahedral arrangement is favored for the formation of these hydrogen bonds. this means each water molecule can interact with four other water molecules through hydrogen bonds, forming a tetrahedral geometry. this geometric arrangement is critical in determining many of the unique properties of water, such as its high boiling point, high surface tension, and the solid state (ice) being less dense than the liquid state.

thus, in summary, each water molecule can form a total of four hydrogen bonds and is tetrahedrally linked to four other water molecules, optimizing the interaction and stabilization provided by hydrogen bonding. this structural arrangement is vital for understanding both the microscopic and macroscopic properties of water.
