Answer: They both have stages where they are born and die which is in the main sequence and supernova and in a human they are born in a womb and die of old age.
Explanation:
The answer is 1. Radiation
2NaOH(aq) + H2SO4(aq) => Na2SO4(s) + 2H2O(l)
This is a neutralization reaction.
Answer:
Explanation:
Hello,
In this case, since the work done at constant pressure as in isobaric process is computed by:
Thus, given the pressure, initial volume and work, the final volume is:
Whereas the pressure must be expressed in Pa as the work is given in J (Pa*m³):
And the volumes in m³:
Thus, the final volume turns out:
Best regards.
Answer:
B. Ionic
Explanation:
RbCl is ionic compound formed from the combination of rubidium (a strongly electropositive element) and chlorine (a strongly electronegative element).
The transfer of an electron from rubidium to chlorine leads to the formation of two oppositely charged ions Rb⁺ and Cl⁻.
In a solid crystal of RbCl, the major intermolecular forces of attraction are electrostatic forces of attraction between oppositely charged ions in the molecules of the crystalline solid.
Ion-dipole attraction only occur when the solid is dissolved in a polar molecule like water. Dispersion forces as well as dipole-dipole forces, though present are weak forces and contribute very little to intermolecular attraction. Hydrogen bonding is not present as there are no hydrogen atoms in solid RbCl.
