A hot air balloon contains 40.0 liters of helium gas at 203 kilopascals. What will be the volume of the helium when the balloon
Anika [276]

<span>1.    </span>To solve this we assume that the gas is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant temperature and number of moles of the gas the product of PV is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

P1V1 =P2V2

V2 = P1 x V1 / P2

 V2 = 203 x 40.0 / 35.0

 V2 =232 L

The diving velocity of a falcon can reach 322 km/hr. If the falcon maintains this velocity for 7.2 seconds (0.002 hours), what w
Degger [83]
Multiply velocity and time and you get 0.644 km, but remember that displacement has a direction and so does velocity, so because velocity is positive in the direction that the falcon is going you have a positive displacement.

BRAINLIEST AND 30 POINTS! concept map for four types of intermolecular forces and a certain type of bond is shown.
Sphinxa [80]

D represents ion-dipole forces that are stronger than the force C.

Explanation:

D represents the ion-dipole force.

C represents the H-bonding forces.

ion-dipole force is a force that is due to electrostatic attraction and has a dipole between an ion and a neutral molecule.

It is electrostatic in nature.

A hydrogen bond is the force between the hydrogen with the electro negative atom of one molecule, to electro negative atom of some other molecule. such as: O, F, N

Ion dipole force is stronger than the H-bonding.

If a solution containing 117.63 g of silver chlorate is allowed to react completely with a solution containing 10.23 g of lithiu
GuDViN [60]

Answer:

18.8 g

Explanation:

The equation of the reaction is;

AgClO3(aq) + LiBr(aq)------>LiClO3(aq) + AgBr(s)

Number of moles of AgClO3 = 117.63 g/191.32 g/mol = 0.6 moles

Number of moles of LiBr = 10.23 g/86.845 g/mol  = 0.1 moles

Since the molar ratio is 1:1, LiBr is the limiting reactant

Molar mass of solid AgBr = 187.77 g/mol

Mass of precipitate formed = 0.1 moles * 187.77 g/mol

Mass of precipitate formed = 18.8 g
