Question

the periodic table of elements
part a
students were using the chemical formula shown here to make ammonia in an online lab simulation
$n_2 + 3h_2
ightarrow2nh_3$
the table shows the elements each student indicated to select for the lab
student material 1 material 2
jose nickel helium
tyler nickel hydrogen
kennedy nitrogen hydrogen
sarah nitrogen helium
which student selected the correct materials for this lab?
a jose
b tyler
c kennedy
d sarah

Explanation:

Step1: Analyze the chemical formula

The formula for making ammonia is $N_2 + 3H_2
ightarrow2NH_3$. We need nitrogen ($N$) and hydrogen ($H$).

Step2: Check student - selected materials

Kennedy selected nitrogen and hydrogen, which are the correct elements according to the formula.

Answer:

C. Kennedy
