Nuclear energy occurs when nuclear bonds split or fuse.

Explanation:

When nuclear bonds or atoms are split in two or more smaller subunits i.e nuclei it releases by products also is termed nuclear fission. The reaction takes place in unstable heavy atoms as uranium. Nuclear binding energy is the energy present in heavy metal.

In nuclear fusion two atomic nuclei fuse to make heavy nuclei in which either energy is released or absorbed.

Electricity is generated by using fusion process. Sun's energy is by fusion process.

Nuclear energy is resultant of nuclear reactions between the atomic nuclei.

Nuclear energy is useful in radioactive radiations (reactors and turbines), to generate electricity, agriculture, medicine and industries etc.

1. How many ATOMS of boron are present in 2.20 moles of boron trifluoride ? atoms of boron.

Answer:

1. How many ATOMS of boron are present in 2.20 moles of boron trifluoride? atoms of boron.

2. How many MOLES of fluorine are present in of boron trifluoride? moles of fluorine.

Explanation:

The molecular formula of boron trifluoride is $BF_3$ .

So, one mole of boron trifluoride has one mole of boron atoms.

1. The number of boron atoms in 2.20 moles of boron trifluoride is 2.20 moles.

The number of atoms in 2.20 moles of boron is:

One mole of boron has ---- $6.023x10^2^3$ atoms.

Then, 2.20 moles of boron has

- $=2.20 mol. x 6.023 x 10^2^3 atoms /1 mol\\=13.25x10^2^3 atoms$

2. Calculate the number of moles of BF3 in 5.35*1022 molecules.

$(5.35x10^2^2 molecules/6.023x10^2^3)x 1mol\\=0.0888mol$

One mole of boron trifluoride has three moles of fluorine atoms.

Hence, 0.0888moles of BF3 has 3x0.0888mol of fluorine atoms.

=0.266mol of fluorine atoms.

A graduated cylinder is filled 25.0 mL with water and a piece of granite is placed in the cylinder, displacing the level to 37.2

kvv77 [185]

The volume of the granite piece in Cm³ is 12.2 cm³

<u><em>calculation</em></u>

volume of granite = (volume of cylinder after placing granite - volume of cylinder before placing granite

= 37.2 ml - 25.0 ml = 12.2 ml

convert ml to Cm³

that is 1 ml = 1 cm³

12.2 ml = ? cm³

<em>by cross multiplication</em>

=(12.2 ml x 1 cm³) / 1 ml = 12.2 cm³
