<u>First part:</u>
2 atoms of Na
6 atoms of N
<u>Second part:</u>
2 atoms of N
2 atoms of Na
Why?
We are given the chemical reaction, so, we can extract the number of atoms for both reactants and products.
We are given the chemical equation:

We can rewrite it as follow:

From the reactants, we have:


From the products we have:



Hence, we have that:
There are <u>6 atoms of N in the reactants</u> and <u>6 atoms of N in the products.</u>
and
There are <u>2 atoms of Na in the reactants</u> and<u> </u><u>2 atoms of Na in the products</u> since we have a balanced equation.
Have a nice day!
Answer:
Molarity of 40 ml of NaoH is 0.3125 mL
Explanation:
As we know
Molarity of acid * volume of acid = molarity of base * volume of base
Substituting the given values, we get

Molarity of 40 ml of NaoH is 0.3125 mL
Answer:
λ = 5.68×10⁻⁷ m
Explanation:
Given data:
Energy of photon = 3.50 ×10⁻¹⁹ J
Wavelength of photon = ?
Solution:
E = hc/λ
h = planck's constant = 6.63×10⁻³⁴ Js
c = 3×10⁸ m/s
Now we will put the values in formula.
3.50 ×10⁻¹⁹ J = 6.63×10⁻³⁴ Js × 3×10⁸ m/s/ λ
λ = 6.63×10⁻³⁴ Js × 3×10⁸ m/s / 3.50 ×10⁻¹⁹ J
λ = 19.89×10⁻²⁶ J.m / 3.50 ×10⁻¹⁹ J
λ = 5.68×10⁻⁷ m
