Answer:
high pressure of 200-300 atm.
low temp. of between 400-500 degrees celsius:this is for continuous development of ammonia since it decomposes at high temp fathermore the reaction is exothermic
a catalyst to speed up the rate of reaction:i guess it is finely divided iron impregnated in aluminium oxide
platinum can be used as a catalyst but it is easily poisoned
hope it helps
Explanation:
Answer:
Use either a vinegar, Borax, or bleach solution in a spray bottle to tackle the mold. Simply spray the solution on showers, baths, basins, tiles, grout, or caulking. Then use either a cleaning cloth or a toothbrush to remove the slime
(C) neon (atomic number 10)
Explanation:
The atom that is chemically inert is Neon with an atomic number of 10.
An atom is chemically inert if it does not willingly take part in chemical reaction.
Atoms takes part in chemical reactions in order to attain a stable configuration as seen in the noble gases.
In the noble gases every enable level is completely filled with the appropriate number of electrons.
- The noble gases are He, Ne, Ar, Kr, Xe
- These elements do not react with others.
- From the given option, Neon is a noble gas and therefore inert.

<span>STP means standard temperature
and pressure at 0°C (273K) and 1 atm (atmosphere). The density of the unknown
gas is 0.63 gram per liter. The deal gas equation is PV = nRT. The n is the
numer of moles and can be represented as mass of the gas, m, divided by the
molar mass, c. so we have,</span>
PV = nRT
PV = (m/c)RT
Since the density is d = m/V
Pc = (m/V)RT
Pc = dRT
c = drT/P
substitute the values into the equation,
c = [(0.63g/L)(0.08206
L-atm/mol-K)(273K)]/(1atm)
<u>c = 14.11 g/mol</u>
