The answer is 10 because if their is 20 molecules of hydrogen then their is one oxygen molecule for each which results in 20 divided by two which equals 10
The volume of a pond being studied for the effects of acid rain is 35 kiloliters (kL). There are 1,000 liters (L) in 1 kL and 10^3 microliters (mL) in 1L.
35 kiloliters ( 1000 liters/1 kiloliters) (10^3 microliters / 1liters)
=35,000,000 microliters
Answer: burning paper
Explanation:
The paper burns in air to form smoke and ash. which makes it a chemical change.
Answer:
1
Explanation:
zeros are not counted when they come before a natural number
Answer:
λ = 1*10⁻¹⁰m
Explanation:
Frequency (f) = 3.0*10¹²MHz = 3.0*10¹⁸Hz
Speed (v) = 3.0*10⁸m/s
Speed (v) of a wave = frequency (f) * wavelength (λ)
V = fλ
Solve for λ,
λ = v / f
λ = 3.0*10⁸ / 3.0*10¹⁸
λ = 1*10⁻¹⁰m
λ = 0.
