the answer is a because the positive cations are attracted to the negative cathode. when the positive ions get to the cathode they pick up an electron and this produces normal sodium.
Answer:
2.77 mol N
Explanation:
M(N2O) = 2*14 + 16 = 44 g/mol
61.0 g * 1 mol/44g = (61/44) mol N2O
N2O ---- 2N
1 mol 2 mol
(61/44) mol x mol
x = (61/44)*2/1 = 2.77 mol N
Answer:
373.15 K
Explanation:
Given data:
Temperature in degree Celsius = 100°C
Temperature in kelvin scale = ?
Solution:
To convert the degree Celsius into kelvin scale we add the given degree Celsius into 273.15.
100°C +273.15 = 373.15 K
I believe it's C, It is a new gas released when atoms are destroyed.
As you said, the answer is 150.
But in all the numbers, there's a comma with two zeros, and so you have to put them in your answer : 150,00
They are the significative numbers.
Hope it helps
