Answer:
1.They are reliable.
2.They dont vary from person to person
<span>In the given chemical equation, 4 moles of nh3 gas react with 5 moles of oxygen to form 6moles of water vapours (h2o). Hence each mole of nh3 contributes to production of 1.5 moles of water vapours.
therefore, the rate of formation of h2o is 1.5*0.5 ms-1, i.e 0.75 moles/sec</span>
Answer:
The volume on the tank is 6, 20 L
Explanation:
We use the formula PV=nRT. We convert the units of pressure in kPa into atm and temperature in Celsius into Kelvin:
0°C=273K
101,325kPa---1 atm
275kPa --------x=(275kPax 1 atm)/101,325kPa= 2,71 atm
PV=nRT --> V=nRT/P
V= 0,750 mol x 0,082 l atm /K mol x 273 K/ 2, 71 atm= <em>6, 20 L</em>
Answer:
To defend against pathogens
Explanation:
True. Although nuclear energy itself is renewable, the material (uranium) used in nuclear power plants is not.
