Which of the following could result from the fission of carbon?

1 answer:

3 0

In nuclear reactions, there are can be two kinds: nuclear fission and nuclear fusion. From the word itself, fusion is combination while fission is breaking. Nuclear reactions are different from chemical reactions. Whereas chemical reactions from compounds by exchanging elements, nuclear reactions add or eliminate subparticles, like protons, neutrons and electrons.

So, when carbon is split up, their protons should add up to 6, which is its atomic number. From the choices, the only obvious answer is two lithium atoms. To investigate further, lithium has an atomic number of 3. So, two lithium atoms would equal to 6.

Therefore, the answer is <span>two lithium atoms.</span>

What is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? As air

Marina86 [1]

We need to know the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure.

The relationship is: As air pressure in an area increases, the density of the gas particles in that area increases.

For any gaseous substance, density of gas is directly proportional to pressure of gas.

This can be explained from idial gas edquation:

PV=nRT

PV= $\frac{w}{M}$ RT [where, w= mass of substance, M=molar mass of substance]

PM= $\frac{w}{V}$ RT

PM=dRT [where, d=density of thesubstance]

So, for a particular gaseous substance (whose molar mass is known), at particular temperature, pressure is directly related to density of gaseous substance.

Therefore, as air pressure in an area increases, the density of the gas particles in that area increases.

How much energy is needed to completely boil a 5.05g sample of water?

Keith_Richards [23]

Given what we know, we can confirm that the amount of heat energy that would be required in order to boil 5.05g of water is that of 11.4kJ of heat.

<h3>Why does it take this much energy to boil the water?</h3>

We arrive at this number by taking into account the energy needed to boil 1g of water to its vaporization point. This results in the use of 2260 J of heat energy. We then take this number and multiply it by the total grams of water being heated, in this case, 5.05g, which gives us our answer of 11.4 kJ of energy required.

Therefore, we can confirm that the amount of heat energy that would be required in order to boil 5.05g of water is that of 11.4kJ of heat.

How many molecules of ethane are present in 64.28 liters of ethane gas (C2H6) at STP

Rom4ik [11]

Answer : The molecule of ethane present in 64.28 L of ethane gas at STP is, $17.277\times 10^{23}$ molecule.

Solution :

At STP,

22.4 L volume of ethane present in 1 mole of ethane gas

64.28 L volume of ethane present in $\frac{64.28L}{22.4L}\times 1mole=2.869moles$ of ethane gas

And, as we know that

1 mole of ethane molecule contains $6.022\times 10^{23}$ molecules of ethane

2.869 moles of ethane molecule contains $2.869\times 6.022\times 10^{23}=17.277\times 10^{23}$ molecules of ethane

Therefore, the molecule of ethane present in 64.28 L of ethane gas at STP is, $17.277\times 10^{23}$ molecule.

How many neutrons does element X have if its atomic number is 44 and its mass number is 151?

Phoenix [80]

To find the number of neutrons, you subtract the atomic number from the mass number of element X. So in this case, it'll be 151-44= the number of neutrons.
