Answer:

much greater

Explanation:

Binding energy of a nucleus is the energy evolved in the formation of a nucleus from free protons and neutrons. It is also defined as the energy that binds nucleons together in the nucleus of an atom.

The nuclear binding energy is far greater than the chemical energy stored in chemical bonds. Nuclear energy is the greatest source of energy which could be exploited to achieve various ends.

What could be done to increase the acceleration of a dog sled? List two possibilities

snow_lady [41]

To increase the acceleration of the dog sled, increase the applied force on the sled and reduce the mass on the sled.

According to Newton's second law of motion, the force applied to an object is directly proportional to product of mass and acceleration of the object.

F = ma

where;

a is the acceleration of the dog sled

$a = \frac{F}{m} \\\\$

To increase the acceleration of the dog sled:

Increase the applied force on the sled.
Reduce the mass on the sled.

Number 8 pls step by stepA sample of gas has a mass of 20.00 g and occupies 44.8 L at STP. What is the molar mass of the gas?

LuckyWell [14K]

A sample of gas has a mass of 20.00 g and occupies 44.8 L at STP. What is the molar mass of the gas?

We know that 1 mol of an ideal gas at STP occupies 22.4 L. So we will use that relationship to find the number of moles of the gas that occupies 44.8 L.

number of moles = 44.8 L * 1 mol/(22.4 L) = 2.00 moles

number of moles = 2.00 moles

Another way of getting the same result is:

STP means that the pressure is 1 atm and the temperature is 273.15 K. And the volume of our sample is 44.8 L

P * V = n * R * T

n = P * V/(R * T)

n = 1 atm * 44.8 L / (0.082 atm*L/mol*K * 273.15 K)

n = 2.00 moles

So two moles of an ideal gas occupies 44.8 L at STP.

The mass of the sample is 20.00 g and we have 2 moles. So the molar mass is:

molar mass = (mass of sample)/(number of moles of the sample)

molar mass = 20.00 g/(2.00 moles)

molar mass = 10.0 g/mol

Another way of solving it:

Since the mass of two moles of our gas is 20.00 g, we can find the mass of 1 mol by solving this:

2.00 moles of gas ______ 20.00 g

1.00 mol of gas _____ x = ?

x = 1.00 mol * 20.00 g/2.00 moles = 10.0 g

So the mass of 1 mol is 10.0 g. Then the molar mass is 10.0 g/mol.

Answer: the molar mass of the gas is 10.0 g/mol
