Answer: Type of Chemical Reaction: For this reaction we have a combination reaction. Balancing Strategies: When we add zinc to hydrochloric acid we end up with zinc chloride, a salt, and hydrogen gas. This reaction is actually a good way to make hydrogen gas in the lab.
Answer:
Chemical reactions involve breaking chemical bonds between reactant molecules (particles) and forming new bonds between atoms in product particles (molecules)

Answer:
To ensure provide and reliable data
Explanation:
Calibration ensures precise repeatable performance while preventing pipetting errors. Just the way measurement standards are established to distinguish valid and invalid processes, pipette calibration standards are designed to ensure the best pipette accuracy.
Answer:
Your answer is 5.63 × 10^14 Hz
We know the value of the speed of light and we are given the wavelength. All we have to do is rearrange the equation to solve for the frequency:
frequency: v = c/ λ
Now just plug in the given values:
v = 3.00 × 10 ^ 8 / 530 × 10^-9
v = 5.66 × 10 ^ 14 Hz
I hope this helps you.
