According to the 2010 U.S. Census, <u>37 </u>percent of women had college degrees compared to approximately <u>35 </u>percent of men.
In 1970 and early 1980, women have surpassed men in number of bachelor's degree or master's degree in united state.
The women gets more degree to gain financial benefits. The gap in earning is greater in female graduate and non- graduate as compare to male graduate and non-graduate. To give education to girls saves lives and builds stronger families, communication and economic too.

Answer:
Write the mole ratio.
Explanation:
The term stoichiometry is coined from two words: stoicheon(atom) and metron(measurement).
Stoichiometry uses the composition or chemical reactions of matter and the moles to quantity the elementary particles of a matter.
In order to do this, we use the mole ratio as the basis of the calculation. The mole is related to different parameters that we can obtained experimentally and theoretically about a reaction.
Answer:
The numbers, positive, negative signs and the symbol of elements are used to represent the ions.
Explanation:
Steps to write the ions:
- Write the symbol of an element. For example in case of magnesium we would write Mg.
- In second step write the number of electrons in superscript that are lost or gained by an atom. For example magnesium atom loses two electrons written as followed, Mg².
- In third step write the charge as superscript after the numbers. For example, magnesium loses two electrons that's why we put the positive sign after 2, because by losing the electrons cations are formed. Mg²⁺
- If the atom of an element lose or gain only one electron then 1 is omitted and only the negative or positive sign are written on superscript. For example in case of sodium cation and chlorine anion, Na⁺ , Cl⁻.
Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.
Answer:
Carbon tetrafluoride
Explanation:
There is one carbon atom and four fluorine that's why its name is carbon tetrafluoride.
It is the covalent compound of carbon and fluorine.
One carbon atom share its four valance electrons with four atom of fluorine.
There are seven valance electrons in one atom of fluorine and it needed only one electron to complete the octet.
That's why one carbon atom with four valance electrons combine with four atoms of fluorine.
It is less soluble in water.
it is readily soluble in ether and alcohol.
Its molecular weight is 88.004 g/mol.
Its molecular formula is CF₄.
It form covalent bond with high strength.
