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
The name of this Ionic Compound is Calcium oxide.
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.
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
Answer:
It gets squeeze together so tightly that four hydrogen nuclei combine to form one helium atom.
