Answer:
diamond is denser because it is more tightly packed than coal
Answer:
1.10 × 10⁻¹² m
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
Speed of Light = Wavelength times Frequency
Explanation:
<u>Step 1: Define</u>
ν = 2.73 × 10²⁰ Hz
<u>Step 2: Find wavelength</u>
3.0 × 10⁸ m/s = λ(2.73 × 10²⁰ Hz)
λ = 1.0989 × 10⁻¹² m
<u>Step 3: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules.</em>
1.0989 × 10⁻¹² m ≈ 1.10 × 10⁻¹² m
It equals 0.005 but plz mark this as the brainliest question plz
The correct answer is false. <span>Chemical equations are balanced not by changing the subscripts of the molecules instead by changing the coefficients of each molecule. However, the subscripts are helpful in balancing equations because they are used in counting the number of atoms or molecules.</span>
