1. Use 3H2(g) + N2 (g) <--> 2 NH3 (g) + 92.4 kJ At equilibrium, if the reaction is heated, the nitrogen (N2) concentration will

Select one:

a. increase

b. remain the same

c. decrease

2. Use 3 H2(g) + N2(g) <--> 2 NH3 (g) + 92.4 kJ

At equilibrium, if the hydrogen (H2) concentration is increased, the ammonia(NH3) concentration will

Select one:
a. increase
c. remain the same
d. shifts back and forth

i'm not sure

explanation:

i'll try whatever you got

im not exactly sure but i think its b!

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

so what is the problem with your lab report and whats the subject of the lab report? i will you
