Remember velocity = distance/time so that mean you would do 60/3 which equals 20 so the speed(velocity) equals 20

Actually when we burn metal salts, we cannot actually
really see distinct lines to appear because in reality, they are not really
visible to the human eye. There is only a certain range of wavelength of light that

The atmosphere contains many gases, most in small amounts, including some pollutants and greenhouse gases.
These contribute to climate change.
Answer:
d. 0.208 M NaOH
Explanation:
M[NaOH] = 23+16+1= 40g/mol
2.40L = 2.4dm3
M=m/Mv
M=20.0g/40g/mol×2.4dm3
M=20.0g ÷ 96
M= 0.208 M NaOH
