A0.500-l sample of h2so4 solution was analyzed by taking a 100.0-ml aliquot and adding 50.0 ml of 0.213 m naoh. after the reaction occurred, an excess of oh2 ions remained in the solution. the excess base required 13.21 ml of 0.103 m hcl for neutralization. calculate the molarity of the original sample of h2so4. (sulfuric acid has two acidic hydrogens.)

Turbo the snail moves across the ground at a pace of 12 feet per day. if the garden is 48 feet away, how many days will it take for the snail to get there?

All cells are made of four types of acids, lipids, proteins, and carbohydrates.

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.
