10 cubic inches
We will use Boyle's law that states that for a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. 
P1 V1 = P2 V2
Where
 P1 is initial pressure = 5 psi
V1 is initial volume = 20 cubic inch
P2 is final pressure = 10 psi
V2 is final volume = unknown
V2 = P1,V1 / P2
V2 = 20 × 5 / 10
V2 = 100/10
V2 = 10 cubic inches

as the difference in electronegativity between two atoms decreases, the tendency for the formation of covalent bonds
Ghella [55]

Answer:

As the difference in electronegativity between two atoms decreases, the tendency for the formation of covalent bonds "increases"

Explanation:

Electronegativity being a chemical property which tells us about the tendency about the atom in order to fascinate the shared pair of the electron towards itself. It is being pretentious by atomic number and the distance as well, by the help of which the valence electrons resides from the charged nucleus. In the scale Pauling scale is used. Being the most electronegative element fluorine is counted. The more the electronegativity, the more electrons will fascinate towards itself.

What’s the answer to this?
Arturiano [62]

Answer : The balanced chemical reaction will be:

3Ca(s)+2Al(NO_2)_3(aq)\rightarrow 2Al(s)+3Ca(NO_2)_2(aq)

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

When solid calcium metal reacts with aqueous aluminum nitrate then it gives aqueous calcium nitrate and solid aluminium.

The balanced chemical reaction will be:

3Ca(s)+2Al(NO_2)_3(aq)\rightarrow 2Al(s)+3Ca(NO_2)_2(aq)

Consider the balanced equation below.
Vikki [24]

Answer: The mole ratio of PCl_3 to PCl_5 is 1: 1

Explanation:

According to the balanced chemical equation ,the number of atoms of each element has to be same on reactant and product side. The stoichiometric coefficients of the species represent their number of moles.

PCl_3+Cl_2\rightarrow PCl_5

Thus in the reactants, there is 1 mole of PCl_3 and 1 mole of Cl_2 molecule. And thus there is 1 mole of PCl_5 in the product as well.

Thus the mole ratio of PCl_3 to PCl_5 is 1: 1

Which graph shows the relationship between the temperature and volume of agas according to Charles's law?Volume vs. Temperature
solmaris [256]
Graph D.

Charles's law states that at the same pressure, the Volumen of a gas is proportional to its temperature (absolute temperature).

This is

V = K T, where K is the constant of proportionallity.

You can also write it in the form

V1 / V2 = T1/ Ts

When Temperature rise Volumen rise in a proportional way. If Temperature doubles Volumen doubles, if Tempearature is decreases to on third, Volume will decrease to one third.
