An atom of beryllium (m = 8.00 u) splits into two atoms of helium (m = 4.00 u) with the release of 92.2 kev of energy. if the or
galben [10]
The kinetic energy of the products is equal to the energy liberated which is 92.2 keV. But let's convert the unit keV to Joules. keV is kiloelectro volt. The conversion that we need is: 1.602×10⁻¹⁹ <span>joule = 1 eV

Kinetic energy = 92.2 keV*(1,000 eV/1 keV)*(</span>1.602×10⁻¹⁹ joule/1 eV) = 5.76×10²³ Joules

From kinetic energy, we can calculate the velocity of each He atom:
KE = 1/2*mv²
5.76×10²³ Joules = 1/2*(4)(v²)
v = 5.367×10¹¹ m/s

almond37 [142]

Answer:

Unequal,different,dipole moment,dipole moment,polar

Explanation:

A bond dipole is the unequal charge distribution between two bonded atoms with different electronegativities .A molecular dipole moment is the three dimensional sum of all the bond dipoles in a molecule.(A dipole moment is measurable physical property;a dipole moment is not measurable unless the molecule is polar.

How many moles of iron (Fe) can be obtained from 3.80 g iron (III) oxide (Fe2O3) reacting with excess carbon monoxide
topjm [15]

0.02375 moles

Explanation:

Fe2O3+CO :. Fe+CO2

We know that

56*2+16*3=160 gm of Fe2O3 can give 56 gm of Fe

So

3.8 gm can give 1.33 gm of Fe

It is equal to 1.33/56 moles of Fe which is equal to 0.02375 moles
