if you were going to try to get the noble gas argon to combine with another element, would fluorine be a good choice?

Answer:

The molar mass is determined by applying the Ideal Gas Law, PV = nRT, where P is the pressure (in atm), V is the volume (in L), n is the number of moles of gas, R is the universal gas constant (0.08206 L∙atm/mol∙K), and T is the temperature (in K).

Hope this helps! :)

Answer:

The equation is balanced

Explanation:

Before a equation can be said to be balanced the number of mole at the reaction side must be equal to number mole at the product side

Let's start with Zn at the reactant side 4 moles of Zn reacts and 4 moles of Zn was obtained from the product side which makes it balanced

Let's take HNO3

For H,10 moles react and 10 moles was obtained in the product side

For N,10 moles react and 8 moles was obtained initially and 2 moles was obtained as well which makes it 10 moles and it makes it balanced

For O,30 moles react and after calculating the total amount of O at the product side it was observed to be 30 which indicates that the equation is balanced...

The equation is absolutely well balanced

Answer:

1.75 atm

Explanation:

When the pressure that a gas exerts on a sealed container changes from 1.75 atm to 2.64 atm, the temperature changes from 315 K to 475 K.

(2.64 atm) x (315 K / 475 K) = 1.75 atm

The pressure and temperature of a gas in a sealed container are directly proportional. An increase in temperature would imply that the pressure also increased.

Answer:1.75 atm

Explanation:

In a closed system, increase in pressure leads to increase in temperature. Using pressure law, P1/T1 = P2/T2

Data =

P1 =?

P2 = 2.64 atm

T1 = 315k

T2 = 475k

From the equation above,

P1 = P2 * T1 / T2

P1 = 2.64*315 / 475

P2 = 1.75 atm

That would be D Stoichiometry.

Answer:

d

Explanation:

According to the forces of attraction, in the process of sublimation the substance changes from solid to gaseous form directly.

What are forces of attraction?

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.

Sublimation is like the changing a solid into a gas without passing through the liquid phase. To sublime a substance, a specific energy has be transferred to the via heat or work.
