What is the partial pressure of hydrogen gas in a mixture of hydrogen and helium if the total pressure is 600 mm Hg and the partial pressure of helium is 439 Torr?

User Avatar

Asked by Wiki User

To convert Torr to mm Hg, divide by 1.33. So, the partial pressure of helium in mm Hg is 439 Torr / 1.33 = 330 mm Hg. To find the partial pressure of hydrogen, subtract the partial pressure of helium from the total pressure: 600 mm Hg - 330 mm Hg = 270 mm Hg. Hence, the partial pressure of hydrogen gas is 270 mm Hg.

What does it mean to describe a noble gas as being inert?

User Avatar

Asked by Wiki User

Describing a noble gas as inert means that it is chemically non-reactive or unreactive. Noble gases have a full set of valence electrons, making them stable and unlikely to form chemical bonds with other elements. This characteristic makes them useful in various applications, such as providing an inert atmosphere in light bulbs or as a shielding gas in welding.

What combines to form helium atoms in a star?

User Avatar

Asked by Wiki User

Helium atoms in a star are formed through the process of nuclear fusion. In the core of a star, hydrogen atoms combine through a series of fusion reactions to form helium atoms. This happens when hydrogen atoms collide and fuse together, releasing energy in the process.

Why is considered that the noble gas is inert gas?

User Avatar

Asked by Wiki User

Noble gases are considered inert because they have a full outer electron shell, making them stable and unlikely to undergo chemical reactions. They do not readily form compounds or ions with other elements due to their low reactivity. This stable electron configuration is the reason why noble gases are used in various applications, such as lighting, lasers, and filling balloons.

How id helium gas artificially produced?

User Avatar

Asked by Wiki User

Helium gas is not artificially produced, as it is created by natural radioactive decay of certain elements, such as uranium and thorium, in the Earth's crust. However, helium can be extracted from natural gas through a process called cryogenic distillation. This involves cooling the natural gas to extremely low temperatures, which causes helium to separate from the other gases present.

What type of gas is used inside foil balloons?

User Avatar

Asked by Wiki User

Foil balloons are filled with helium. Helium is lighter than air and because of this, it is one of the gases that can make a balloon float. It's the preferred gas for these type of balloons because it isn't flammable and is inert, meaning undesired chemical reactions are rare.

What happens to atoms size as you move down the periodic table in the noble gases?

User Avatar

Asked by Wiki User

As you move down the periodic table in the noble gases, the atomic size generally increases. This is because the number of energy levels, or electron shells, increases down the group. With each additional energy level, the atomic radius expands, resulting in larger atoms.

Do a research on the internet and give for the following metals and non metals at least two usages in daily life gold silver iodine and helium?

User Avatar

Asked by Wiki User

Gold is used in jewelry, electronics (due to its excellent conductivity), and dentistry (for dental crowns and fillings). Silver is used in photography (as silver nitrate), silverware, and as a catalyst in chemical reactions. Iodine is used in medicine (as an antiseptic and in thyroid treatments) and as a disinfectant in water purification systems. Helium is used in balloons and airships due to its lighter-than-air property, as well as in cryogenics and cooling applications.

What is the quantum number set of the ground-state electron that is found in helium but not in hydrogen?

User Avatar

Asked by Wiki User

The quantum number set of the ground-state electron in helium, but not in hydrogen, is (1s^2) or (n=1, l=0, ml=0, ms=0). It indicates that the electron occupies the 1s orbital, which has a principal quantum number (n) of 1, an orbital angular momentum quantum number (l) of 0, a magnetic quantum number (ml) of 0, and a spin quantum number (ms) of 0.

What would make it possible for a magnesium to have a noble gas configuration?

User Avatar

Asked by Wiki User

Magnesium has an atomic number of 12, which means it has 12 electrons. To achieve a noble gas configuration, magnesium would need to lose both of its valence electrons. This can be achieved through chemical reactions, where magnesium can form ionic compounds by transferring its electrons to other elements, such as oxygen or chlorine.

What element is a noble gas in the first energy level?

User Avatar

Asked by Wiki User

There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.

How is Xenon separated by other matierials found with it?

User Avatar

Asked by Wiki User

Xenon can be separated from other materials through several methods, including fractional distillation and cryogenic distillation. In fractional distillation, a mixture of gases is heated, and as each gas has a different boiling point, they can be separated based on their different vapor pressures. Cryogenic distillation, on the other hand, involves cooling the mixture to very low temperatures to condense and separate the different gases based on their boiling points.

Popping and inhaling helium from balloons will not permanently change your voice. The effect of inhaling helium on the vocal cords is temporary and lasts only a few minutes. It is not recommended to inhale helium for prolonged periods as it can be potentially harmful.

Does the outer shell of noble gases make it more or less likely to bond with other elements?

User Avatar

Asked by Wiki User

The outer shell of noble gases is full or complete, which makes it very stable. Because of this stability, noble gases are generally less likely to bond with other elements and form compounds. They are known for their inertness or lack of reactivity.

Why do noble gases combine with atoms of any other element?

User Avatar

Asked by Wiki User

Noble gases are generally unreactive due to their full outer electron shells, making them stable. However, under certain conditions such as high pressure or high temperature, noble gases can react with atoms of other elements to form compounds. This occurs as these conditions can force electrons from the noble gas to form bonds with other atoms, allowing them to combine.

What do other elements do to acquire a noble gas configuration?

User Avatar

Asked by Wiki User

Other elements can acquire a noble gas configuration by either gaining or losing electrons. Elements on the left side of the periodic table, such as alkali metals, tend to lose electrons to achieve a noble gas configuration. Elements on the right side of the periodic table, such as halogens, tend to gain electrons to achieve a noble gas configuration. Elements in the middle of the periodic table may gain or lose electrons to acquire a noble gas configuration, depending on the specific element and its properties.

Are helium atoms on the sun and on earth likely to have the same physical properties?

User Avatar

Asked by Wiki User

Helium atoms have the same physical properties regardless of whether they are found on the Sun or on Earth. The properties of an element, such as its atomic number and mass, remain constant regardless of its location. However, the environment in which helium atoms exist can affect their behavior, such as temperature and pressure differences, which could influence their physical interactions.

Why alpha rays called helium nuclei?

User Avatar

Asked by Wiki User

Alpha rays are called helium nuclei because they consist of two protons and two neutrons, which is the same composition as a helium nucleus. When an atom undergoes alpha decay, it emits an alpha particle, which is essentially a helium nucleus that is ejected from the atom.
