They fully ionise in water to form their conjugate base.
They form aqueous solutions with a pH greater than 7.
They conduct electricity in aqueous solution.

In the reaction between a crushed antacid tablet and vinegar what gas is emitted

Asample of air with a volume of 2.20m3 at a pressure of 105 kpa and a temperature of 30c is cooled to 10c and the pressure is reduced to 75.0 kpa. what is the new volume? 6.9 1.34 2.56 43.0 2.88

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!
