Answer:
Yes N3- is correct ion notation. The N element is in the form N2 . Also it is a triple covalent bond and so this correct
The answer should be (A) liquid to solid. This is because it releases the heat absorbed by it when it had changed into liquid.
Answer:
1.0 mole
Explanation:
From the question given above, the following data were obtained:
Volume (V) = 5 L
Temperature (T) = 205 K
Pressure (P) = 340 KPa
Gas constant (R) = 8.31 KPa.L/Kmol
Number of mole (n) =?
Using the ideal gas equation, the number of mole of the gas in the container can be obtained as follow:
PV = nRT
340 × 5 = n × 8.31 × 205
1700 = n × 1703.55
Divide both side by 1703.55
n = 1700 / 1703.55
n = 1.0 mole
Thus, the number of mole of the gas in the container is 1.0 mole
Answer:
A catalyst provides an alternative pathway for the reaction, that has a lower activation energy. ... Increasing the temperature will mean there are more particles with high energy, greater than the activation energy, so a higher chance of a successful reaction.
