Answer:
The answer to your question is 5.019 x 10²² atoms
Explanation:
Data
mass of ammonium carbonate = 8 g
number of atoms = ?
Process
1.- Calculate the molar mass of (NH₄)₂CO₃
(NH₄)₂CO₃ = (14 x 2) + (1 x 8) + (12 x 1) + (16 x 3)
= 28 + 8 + 12 + 48
= 96 g
2.- Calculate the number of atoms
96 g ------------------ 6.023 x 10²³ atoms
8 g ----------------- x
x = (8 x 6.023 x 10²³) / 96
x = 5.019 x 10²² atoms
Answer:
Asexual reproduction
Explanation:
Cells are able to re produce themselves without other cells needed. If cells need others to make more then how would that work and plus we wouldn't have the theory of cells existing.

Answer:
When water changes to a solid or gas, it's said that water changes to a different state of matter
Explanation:
Even when water physical form changes, the molecules stay the same. Water's molecules contains two hydrogen atoms that is bonded with one oxygen atom.
F.Wave C has a higher frequency than wave D
D. Wave B would sound quieter than wave C
B. Wave D has a higher amplitude than wave A
Explanation:
- A high amplitude wave is a high-energy wave, and a low-amplitude wave is a low-energy wave.
- In sound waves, a high amplitude sound will be loud, and a low amplitude sound will be quiet.
- Frequency is the number of ways that pass by each second, measured in hertz.
- The amplitude and frequency are the two factors that affect the energy which is transferred by a wave.
- The height of the wave, and the number of waves passed by each second in case of amplitude and frequency.
