Answer:
Explanation:
The triple point of carbon dioxide is 5.11 atmosphere at -56.6 degree celsius . At pressure greater than 5.11 , solid carbon dioxide liquefies , as it is warmed. At pressure lesser than 5.11 atmosphere , it will go into gaseous state without liquefying . Excessive pressure helps liquification process.
So maximum pressure required is 5.11 atmosphere. Beyond this pressure , solid CO2 will liquify.
Answer:
1 mole FeCr2/ 1 mole FeCr2O4
Explanation:
We have to write down the equation of the reaction before we can answer the question;
2C(s) + FeCr2O4(s) -------> FeCr2(s) + 2CO2(g)
By inspection of this reaction equation, we can clearly see that the mole ratio of the reactants and products is 2:1:1:2.
Specifically, the ratio of chromites to ferrochrome is 1:1
Hence;
The mole ration required to convert chromites to ferrochrome is;
1 mole FeCr2/ 1 mole FeCr2O4
Answer:
29.85°C
Explanation:
0°K is absolute zero. That is is same as -273.15°C.
To find C, subtract 273.15 from the temperature in °K.
303K - 273.15°C = <em><u>29.85°C</u></em>
The element has three unpaired electrons in its p orbital is nitrogen (atomic number 7).
1) Sperm is produced in the testes. 2) sperm leaves the testes through the seamen duct, 3) in the seaman duct fluids from the glands are added to the Sperm, 4) seaman is released form the penis.
