Answer:
Copper
Explanation:
Within intermolecular forces, ion-dipole is the strongest, followed by hydrogen bonding, then dipole-dipole, and then London dispersion.
The wavelength of a sound wave moving at 340 m/s and with a frequency of 256 Hz is calculated using the the below formula
wavelength = speed of the wave/frequency
speed of the wave = 340 m/s
frequency = 256 Hz
wavelength is therefore = 340/256 = 1.32 m
A balance is used to determine mass
Answer is: in chemical reaction with with weak acid, sodium carbonate produce carbonic acid (H₂CO₃), which decomposes into carbon(IV) oxide (fizzy bubbles) and water.
Balanced chemical reaction:
Na₂CO₃ + 2HClO → CO₂(g) + H₂O + 2NaClO.
Chemical decomposition is the separation of a carbonic acid into water and carbon dioxide: H₂CO₃ → CO₂ + H₂O.
To answer this question, I need to know what the picture looks like.
