The concept of an ideal gas is used to explain(1) the mass of a gas sample(2) the behavior of a gas sample(3) why some gases are monatomic(4) why some gases are diatomic

Answers

Ideal gas is used to explain the behavior of a gas sample. In ideal gas law, the equation is PV=nRT where R has a constant of 0.0821L.atm/mol.K. It can explain the behaviior of a gas in three types: mole, mass and density. The ideal gas often observed in a high temperature with low pressure as to potential energy becomes less significant compared to the kinetic energy.

Final answer:

The concept of an ideal gas is chiefly used to explain the behavior of a gas sample according to the ideal gas law. It's not primarily used to determine the mass of a gas sample, or whether a gas is monatomic or diatomic.

Explanation:

The concept of an ideal gas is primarily used to explain the behavior of a gas sample. An ideal gas is a theoretical gas composed of randomly moving, non-interacting point particles. It follows the ideal gas law which is PV=nRT, where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the absolute temperature. The ideal gas law allows us to predict how a gas will behave under different conditions of pressure, volume, and temperature.

The mass of a gas sample is inherently tied to the moles of gas, per the molar mass concept in the ideal gas law. As for whether a gas is monatomic or diatomic, this depends on the atomic structure and bonding of the specific gas species, and not the ideal gas concept itself.

The point at which a substance is at complete equilibrium is called? User: a hydrogen bond is a special form of what type of bond

Answers

I don't know what the answer to your first question is. All of my teachers have only called it the equilibrium point. However for your second question, a hydrogen bond is a special type of dipole-dipole attraction. Only oxygen, nitrogen, and fluorine are able to make them when bonded with hydrogen. Hydrogen bonding is what makes water have such a high boiling point considering how light the molecule is.

The Haber process can be used to produce ammonia (NH3) from hydrogen gas (H2) and nitrogen gas (N2). The balanced equation for this process is shown below.3H2 + N2 mc025-1.jpg 2NH3

The molar mass of NH3 is 17.03 g/mol. The molar mass of H2 is 2.0158 g/mol. In a particular reaction, 0.575 g of NH3 forms. What is the mass, in grams, of H2 that must have reacted, to the correct number of significant figures?

Answers

Answer : The mass of $H_2$ in grams is 0.102g.

Solution : Given,

Molar mass of $NH_3$ = 17.03 g/mole

Molar mass of $H_2$ = 2.0158 g/mole

Given Mass of $NH_3$ = 0.575 g

First we have to calculate the moles of $NH_3$ .

$\text{ Moles of }NH_3=\frac{\text{ Given mass of }NH_3}{\text{ Molar mass of }NH_3}$ = $(0.575g)/(17.03g/mole)$ = 0.0337 moles

The given balanced equation is,

$3H_2(g)+N_2(g)\rightarrow 2NH_3(g)$

From the above reaction, we conclude that

2 moles of $NH_3$ produced from 3 moles of $H_2$

then the 0.0337 moles of $NH_3$ produces to give $(3moles* 0.0337moles)/(2moles)$ moles of $H_2$

The moles of $H_2$ = 0.0505 moles

The mass of $H_2$ = Moles of $H_2$ × Molar mass of $H_2$ = 0.0505 moles × 2.0158 g/mole = 0.10179 g

The mass of $H_2$ in the correct number of significant figures is 0.102 g.

Talc _____. is the hardest known mineral has a Mohs hardness of 1 has a Mohs hardness of 10 is harder than quartz

Answers

Talc is the softest known mineral which is why it has a Mohs hardness of 1. The Mohs Hardness Scale is the most popular way of measuring and testing the hardness of a mineral. The Mohs hardness ranges from 1 (softest) to 10 (hardest). The hardest mineral with a Mohs hardness of 10 is diamond.

Talc is a clay mineral composed of magnesium silicates commonly used in making powder, paint, cosmetics, and many other products.

The answer is has a Moh's hardness of 1.
