A gas has a pressure of 7 atm at 227°C. What will its pressure be at 27°C? The volume and amount of gas is constant. Hint: Convert temperature to Kelvin before calculating (°C + 273 = K)

What were the success and failures that came to boyle’s excitements?

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

Match the mixture with the substance// i really need on this guys (it’s a pic btw)
