Hydroxylamine is a weak molecular base with kb = 6.6 x 10-9. what is the ph of a 0.0500 m solution of hydroxylamine?
7nadin3 [17]
Answer is: pH of hydroxylamine solution is 9,23.

Kb(NH₂OH) = 1,8·10⁻⁵<span>.
c</span>₀(NH₂OH)<span> = 0,0500 M = 0,05 mol/L.
c(NH</span>₂⁺) = c(OH⁻) = x.

c(NH₂OH<span>) = 0,05 mol/L - x.
Kb = c(NH</span>₂⁺) · c(OH⁻) / c(NH₂OH).

0,0000000066 = x² /  (0,05 mol/L - x). 

solve quadratic equation: x = c(OH⁻) = 0,000018 mol/L.<span>
pOH = -log(</span>0,000018 mol/L) = 4,74.<span>
pH = 14 - 4,74 = 9,23.</span>

The thing that the discovered is a "partially molten state"<br> What would that be considered as
castortr0y [4]

Answer:

liquid and solid

Explanation:

Research scientists of scotland discovered a new state of the matter which consists of both liquid and solid. Scientifically there are  three states of matter i.e Solid, Liquid and Gas, but now there are chances of one more state of matter which which consists of more than one state of the existing three states of the matter which have both liquid and solid state.  

This discovery took place with the help of artificial intelligence of today's world which is transforming the world  day by day.

The State is considered to be true as it is thermodynamically stable state of the matter.

If you have 5 moles of carbon dioxide at 30degrees C and under 600mmHg of pressure, what will the volume be
trapecia [35]

Answer:

157.64 L

Explanation:

We'll begin by converting 30 °C to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

T(°C) = 30 °C

T(K) = 30 °C + 273

T (K) = 303 K

Next, we shall convert 600 mmHg to atm. This can be obtained as follow:

760 mmHg = 1 atm

Therefore,

600 mmHg = 600 mmHg × 1 atm / 760 mmHg

600 mmHg = 0.789 atm

Finally, we shall determine the volume of the gas. This can be obtained as follow:

Number of mole (n) = 5 moles

Temperature (T) = 303 K

Pressure (P) = 0.789 atm

Gas constant (R) = 0.0821 atm.L/Kmol

Volume (V) =?

PV = nRT

0.789 × V = 5 × 0.0821 × 303

0.789 × V = 124.3815

Divide both side by 0.789

V = 124.3815 / 0.789

V = 157.64 L

Therefore, the volume of the gas is 157.64 L

Elements in group 16 want to bond with elements in group ___.
Trava [24]

Answer:

Two

Explanation:

Elements in group 16 wants to bond with elements in group IIA, the group of alkaline earth metals.

  • The bonding will make it easier for them complete their octet.
  • Elements in group 16 has 6 valence electrons.
  • To have a complete octet, they require 2 more electrons.
  • Group II elements are willing donors as they are metals.
  • For Group II elements to fill their octets, they must lose two electrons.
  • So the willingness of group II elements to lose two electrons and the readiness for group 16 elements to gain the electrons makes the desire one another.

If you were about 10 kilometers above earth, what would the pressure approximately be?
Sliva [168]

Answer:

About 25 kPa  

Explanation:

Pressure decreases with height above sea level.

The calculation is rather complicated, so I will refer to the figure below.  

It shows that the pressure at 10 km is about 25 kPa.
