Answer:
A: 92.02 g
Explanation:
Equation of the reaction;
N2 (g)+ 2O2(g)------> 2NO2(g)
Note that the balanced reaction equation is the first step in solving any problem on stoichiometry. Once the reaction equation is correct, the question can be easily solved...
The outermost electrons of the atom are either lost or gained by one of the atoms to the other. therefore the atom gains negative charge when gaining and positive charge when losing
Answer:
The answer is 3. Arrhenius acids form hydronium ions in water
Explanation:
From the notes my teacher gave me.
Hopefully this helps, have a nice day.
Also by any chance, do you go to Freedom High School?
The element is most likely PHOSPHORUS.
Phosphorus is an element with an atomic number of 15. The electronic configuration of the element is 2,8,5. This configuration implies that, each atom of phosphorus has three sub shell, the first sub shell has 2 electrons, the second has 8 electrons while the outermost sub shell has 5 electrons. The electrons in the outermost shell are also called the valence shell. Thus, phosphorus has 5 electrons in its valence shell.
