Answer:
Boyle's law, which describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system. Among his works, The Sceptical Chymist is seen as a cornerstone book in the field of chemistry.
The equation for determining the energy of a photon of electromagnetic radiation<span> is #E=hnu# , where E is energy in Joules, h is Planck's constant, #6.626 xx 10^(-34)J*s# , and #nu# (pronounced "nu") is the frequency

Well some animals can survive in the dry land because they don't grow up by water
Answer:a) 0.1 mole. b) 4g. c) 2% d) 196 mL
Explanation: in 200mL , 0.1mole
mw NaOH = 40g/mol —> 4g in 0.1 mole
4g in 200mL so 2g in 100mL
density NaOH = 1g/mL so if 4g in 200 mL, 4mL , 196 mL water
