Answer:
ν ≈ 4.7 × 10¹⁴ Hz
General Formulas and Concepts:
<u>Chem</u>
Speed of Light = Wavelength times Frequency
Explanation:
<u>Step 1: Define</u>
λ = 6.4 × 10⁻⁷ m
<u>Step 2: Solve for ν
</u>
3.0 × 10⁸ = 6.4 × 10⁻⁷ · ν
ν = 4.6875 × 10¹⁴ Hz
<u>Step 3: Check</u>
<em>We are given 2 sig figs. Follow sig fig rules.</em>
4.6875 × 10¹⁴ Hz ≈ 4.7 × 10¹⁴ Hz

According to Bronsted-Lowry acid concept
an acid is a that donate a proton" and a base is a "proton acceptor."so
will look for that molecule to which <span><span>H2</span>O</span> "donates" <span>H+</span>to become <span>O<span>H−</span></span>. so answer will be..
. <span>N<span>H3</span>+<span>H2</span>O→N<span>H+4</span>+O<span>H<span>−
so correct option is NH3
hope it helps</span></span></span>
