<u>Following are some important uses of hydrogen:</u>

•Hydrogen is used in the synthesis of ammonia and the manufacture of nitrogenous fertilizers.

•Hydrogenation of unsaturated vegetable oils for manufacturing vanaspati fat.

•It is used in the manufacture of many organic compounds, for example, methanol.

USES OF HYDROGEN

commercial fixation of nitrogen from the air in the Haber ammonia process hydrogenation of fats and oils

methanol production, in hydrodealkylation, hydrocracking, and hydrodesulphurization rocket fuel
welding
production of hydrochloric acid
reduction of metallic ores
for filling balloons (hydrogen gas much lighter than air; however it ignites easily) liquid H2 is important in cryogenics and in the study of superconductivity since its melting point is only just above absolute zero

Dry ice is solid carbon dioxide. Instead of melting, solid carbon dioxide sublimes according to the following equation: CO2(s)→C

GREYUIT [131]

Answer:

$m=8.79kg$

Explanation:

First of all we need to calculate the heat that the water in the cooler is able to release:

$Q=\rho * V*Cp*\Delta T$

Where:

Cp is the mass heat capacity of water
V is the volume
$\rho$ is the density

$Q=1 g/cm^3 *15000 cm^3*4.184 \frac{J}{g*^{\circ}C}*(10-90)^{\circ}C$

$Q=-5020800 J=-5020.8 kJ$

To calculate the mass of CO2 that sublimes:

$-Q=\Delta H_{sub}*m$

Knowing that the enthalpy of sublimation for the CO2 is: $\Delta H_{sub}=571 kJ/kg$

$5020.8 kJ=571 kJ/kg*m$

$m=\frac{5020.8 kJ}{571 kJ/kg}=8.79kg$

If you pump air into cycle tyre a slight warming effect is noticed at valve stem why

Mashutka [201]

As the air molecules move through the valve they have friction as they hit the walls, and its this friction that causes it to heat up.

The base-dissociation constant, kb, for pyridine, c5h5n, is 1.4x10-9 the acid-dissociation constant, ka, for the pyridinium ion,

sp2606 [1]

We are given the base dissociation constant, Kb, for Pyridine (C5H5N) which is 1.4x10^-9. The acid dissociation constant, Ka for the Pyridium ion or the conjugate acid of Pyridine is to be determined. We know from our chemistry classes that:

Kw = Kb * Ka

where Kw is always equal to 1x10^-14

so, to solve for Ka of Pyridium ion, substitute Kb to the equation together with Kw and solve for Ka:

1x10^-14 = 1.4x10^-9 * Ka
solve for Ka

Ka = 7.14x10^-6

Therefore, the acid dissociation constant of Pyridinium ion is 7.14x10^-6.
