Answer:
Explanation:
Raoult's law is a tool that allows to determine vapour pressure of solutions. The formula is:
<em>(1)</em>
Where
P is Pressure of solution and solvent and X is mole fraction.
Moles of solute and solvent are:
Biphenyl:
11.5g×(1mol /154.21g) = <em>0.0746mol</em>
Benzene
31.9g×(1mol /78.11g) = <em>0.408mol</em>
Mole fraction of benzene is:
= <em>0.846</em>
Replacing in (1):

Define ionization energy and explain why the second aisle and ionization energy of the element is higher than its ionization energy
The energy needed to remove one or more electrons from a neutral atom to form a positively charged ion is a physical property that influences the chemical behavior of the atom. By definition, the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase.
The process by which the first ionization energy of hydrogen is measured would be represented by the following equation.
H(g) -----> H+(g) + e- deltaHo = -1312.0 kJ/mol
Answer:
It is a network solid, a lattice of many covalent bonds (like diamond, except that it is black rather than transparent).
Explanation:
The germ theory of disease
eventually led to the development of certain types of vaccines. This theory explains
that specific type or types of microorganisms, which are bacteria, virus, fungi,
or protest species, cause some diseases. These organisms can enter the human
body, and can even grow and reproduce, causing infection, inflammation to
specific organs in the body, and others. One particular vaccine developed successfully
through this understanding is the smallpox vaccine, which is an important
vaccine up to this day.
6CO2 + 6H2O → C6H12O6 + 6O2.
