Which of the following pure compounds will exhibit hydrogen bonding?

zimovet [89]

Explanation:

For a compound to show hydrogen bonding it is necessary that the hydrogen atom of the compound should be attached to more electronegative atom like fluorine, oxygen or nitrogen.

For example, $CH_{3}CH_{2}OH$ , $CH_{3}NH_{2}$ and $NH_{3}$ all these compounds contain an electronegative atom attached to hydrogen atom.

Therefore, these pure compounds will exhibit hydrogen bonding.

Thus, we can conclude that out of the given options $CH_{3}CH_{2}OH$ , $CH_{3}NH_{2}$ and $NH_{3}$ are the pure compounds which will exhibit hydrogen bonding.

2 HI(g) = H2(g) + 1,(9) K, - Party met = 0.0016 The decomposition of HI(g) at 298 K is represented by the equilibrium equation a

givi [52]

Answer:

Explanation:

From the equation of reaction,

Kc = [H2][I2]/[HI]^2

Kc = 0.0016

Initial pressure of HI = 200 torr

Let the equilibrium pressure of I2 be y

Mole ratio of H2 to I2 from the equation of reaction is 1:1, equilibrium pressure of H2 is also y

Mole ratio of HI to I2 is 2:1, equilibrium pressure of HI is (200 - 2y)

0.0016 = y×y/(200 - 2y)^2

y^2 = 0.0016(40,000 - 800y + 4y^2)

y^2 = 64 - 1.28y + 0.0064y^2

y^2 - 0.0064y^2 + 1.28y - 64 = 0

0.9936y^2 + 1.28y - 64 = 0

y^2 + 1.29y - 64.41 = 0

The value of y must be positive and is obtained by the use of the quadratic formula.

y = [-1.29 + sqrt(1.29^2 - 4×1×-64.41)] ÷ 2(1) = [-1.29 + 16.10] ÷ 2 = 14.81 ÷ 2 = 7.4

Equilibrium pressure of I2 is 7.4 torr because the relationship between I2 and HI is direct in which increase in one quantity (initial pressure of HI) would result to a corresponding increase in the other quantity (equilibrium pressure of I2)

Explain how temperature and precipitation are affected by latitude and the sun's rays.

Contact [7]

Latitude and Temperature

At the equator, the Sun's rays are most direct. This is where temperatures are highest. At higher latitudes, the Sun's rays are less direct. The farther an area is from the equator, the lower its temperature.

At STP, adding salt to a 200 mL sample of water produces a saturated 1.7 M solution. How many grams of salt (NaCl) must be added

Illusion [34]

Answer:

$m_{NaCl}=19.9gNaCl$

Explanation:

Hello!

In this case, since the formula for the calculation of molarity is:

$M=\frac{n}{V}$

Whereas we can compute the moles of the solute as shown below, making sure the volume is in liters:

$n=M*V$

Thus, by plugging in we obtain:

$n=0.200L*1.70mol/L=0.170molNaCl$

Next, since the molar mass of NaCl is 58.44 g/mol, we obtain the following mass:

$m_{NaCl}=0.170molNaCl*\frac{58.44gNaCl}{1molNaCl}\\\\m_{NaCl}=19.9gNaCl$

Best regards!

Describe the trend for atomic radius from left to right across a period. Use atomic

Allisa [31]

As you move across a period, the atomic radii decreases. ... As you move across a period, electrons are added to the same energy level while protons are also being added. The concentration of more protons creates a higher effective nuclear charge.
