A sample of hydrogen gas collected by displacement of water occupied 30mL at 24 C on a day when the barometric pressure was 736t

shusha [124]

Answer:

$v_2=6,48*10^{-4}L$

Explanation:

From the question we are told that:

Volume of hydrogen $V_1=30mL=>30*10^{-3}$

Temperature $T_1=24C=>24+273=>297k$

Pressure of water $P_1=22.4torr=>\frac{22.4}{760}=0.0295atm$

Let

STP(Standard Temperature and pressure)

$T_2=273K$

$P_2=1atm$

Generally the equation for ideal gas is mathematically given by

$\frac{p_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

Therefore

$v_2=\frac{P_1v_1T_2}{T_1P_2}$

$v_2=\frac{0.0295*30*10^{-3}*273}{297*1}$

$v_2=6.48*10^{-4}L$ (at STP(Standard Temperature and pressure))

What typefs) of bonding would be expected for each of the following materials: solid xenon, calcium fluoride (CaF, bronze, cadmi

klio [65]

Answer:

a) Solid Xenon - only van der waals forces of attractions.

b) Calcium Fluoride - Ionic Bonding

c) Bronze - Metallic Bonding

d) Cadmium telluride - Covalent bonding with slight ionic character.

e) Rubber - Covalent bonding with some van der Waals forces of attraction.

f) Tungsten - Metallic bonding

Explanation:

a) Xenon is a noble gas having fully filled stable electronic configuration.

So, there is no bonding between xenon atoms in solid xenon.

Only van der waals forces of attraction are found.

b) Calcium fluoride is an ionic compound formed from calcium (2+) and Fluoride ion.

c) Bronze is an alloy formed mainly from copper and tin which are both metals.

So, metallic bonding is in found in bronze.

d) Cadmium telluride is formed form cadimium (2+) ion and Telluride ion with -2 charge.

So, it has slight ionic character with predominant covalent bonding

e) Rubber is a polymer which is formed from isoprene units.

So, covalent bonding exists along with van der waals forces.

f) Tungsten is a metal. So, metallic bonding is found between the atoms of tungsten.

How has research for alternative energy sources been affected by changes in society?

rodikova [14]

Research for alternative energy sources have been positively affected, because of other reasons (excluding those EliteAnswers listed), such as:

1) Renewability: This means that resources are replaced as fast as they are used, meaning that they would not run out

2) Cleaner: Most alternative energy would not have the effect of polluting the earth after it is used, and may be easier to clean (if even need to)
