Why do larger gases such as Neon produce more color bands (line spectra) than smaller gases like Hydrogen?
LekaFEV [45]
Larger gases produces more spectral lines than the smaller gases because they have more orbitals in their atoms.
Hydrogen has only one orbital in which an electron orbits. At the excited state, that is, when the electron gains energy, the number of energy level it can transcend is very few. For larger elements, they have more orbitals and when excited, they can move from the ground state to other energy levels at which they produce various unique spectral lines.

How much potassium chloride is needed to make 0.500 m solution with 1.50 L of water?
Andrew [12]

Answer:

55.9 g KCl.

Explanation:

Hello there!

In this case, according to the definition of molality for the 0.500-molar solution, we need to divide the moles of solute (potassium chloride) over the kilograms of solvent as shown below:

m=\frac{mol}{kilograms}

Thus, solving for the moles of solute, we obtain:

mol=m*kilograms

Since the density of water is 1 kg/L, we obtain the following moles:

mol=0.500mol/kg*1.50kg\\\\mol=0.75mol

Next, since the molar mass of KCl is 74.5513 g/mol, the mass would be:

0.75mol*\frac{74.5513g}{1mol}\\\\55.9g \ KCl

Regards!

A container of oxygen with a volume of 60 L is heated from 300 K to 400 k, What is the new volume?
Lunna [17]

Answer:

80L

Explanation:

V1/T1 = V2/T2

V2 = V1 T2/T1

T1 = 300K

V1 = 60L

T2 = 400K

V2 = ?

V2 = V1 T2/T1

V2 = (60L)(400K) / (300K)

V2 = 80L

Which of the following objects would take you the greatest amount of force to accelerate?
horsena [70]

Complete question is;

Which of the following object would take you the greatest amount of force to accelerate.

A) a soccer ball with a mass of 0.5 kg

B) a refrigerator with a mass of 200 kg, C) a bike with a mass of 25 kg

D) a car with a mass of 5,000 kg,

Answer:

D) a car with a mass of 5,000 kg

Explanation:

Formula for force is;

F = ma

Where;

F is force

m is mass

a is acceleration

Now, Force is directly proportional to the acceleration and mass.

Thus, the higher the mass, the greater the force.

Thus, the object that will require the most force is the one that has the highest mass.

Looking at the options, the one with the highest mass is option D.
