Cup and liter both are measuring units.

A balloon is filled with a volume of 21.55 cups

Volume of balloon in liter L = ?

When we convert the measurement of cup into liter,

1 US customary cup = 0.236588 L

21.55 cups = 0.236588 x 21.55 = 5.0984765

So the volume of balloon in liter = 5.0984765 Liter

A helium balloon has a volume of 2.5 L. When heated to 343.5K the pressure of the gas is 66.7 kPa. How many moles of He gas woul

Lelu [443]

Answer:

0.06mole

Explanation:

Given parameters:

Volume of balloon = 2.5L

T = 343.5K

P = 66.7kPa; in atm gives = 0.66atm

Unknown:

Number of moles of He = ?

Solution:

To solve this problem, we use the ideal gas equation.

It is mathematically expressed as;

Pv = nRT

where p is the pressure

v is the volume

n is the number of moles

R is the gas constant

T is the temperature

0.66 x 2.5 = n x 0.082 x 343.5

n = 0.06mole

Anton [14]

Hello! Here's the answer I was able to come up with:

Why does Na have only one dot?

Sodium, or Na, has only one valence electron. (This makes the atom tend to participate in ionic bonding and "give" its single valence electron to an atom like chlorine.)

Why do none of these diagrams show more than 8 dots?

It is physically impossible for an atom to have more than 8 electrons in its valence layer, according to the Octet Rule.

What relationship do you notice between the dots in these two charts?

The dot diagram for each element represents the number of electrons each element will have in its outermost, or valence, shell. (2-8-8)

The number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table. Why?

An atom can have a maximum of two electrons in its innermost layer. Hydrogen and helium have only one and two electrons, respectively, so they don't have enough electrons to actually have more than one layer. Therefore, their outermost layer is, in fact, their only layer. This is why the number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table.

Virty [35]

Explain whether this is a chemical or physical change, and why. does it involve elements, compounds, mixtures, or pure substances?

If the process involves a chemical reaction then surely it is a chemical change where new bonds are being formed from the collision of the reactants.

Describe how many atoms are involved before and after. what do you notice about the number of atoms?

From the balanced chemical reaction, we see that we need 1 mol of N2 gas and 3 mol of H2 in order to form 2 mol of NH3.
