ME AYUDAN POR FAVOR Una muestra de gas tiene un volumen de 0,5 litros a 20°C y 750 mm Hg de presión. Calcular el volumen de gas si la temperatura se aumenta a 40°c y la presión cambia a 1,026 atm.

Iknow the answer is a but i don't know why

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1

How are isotopes of the same chemical element alike? how are they different?
