What is the pH at the equivalence point when 35.0 mL of a 0.300 M solution of acetic acid (CH3COOH) is titrated with 0.100 M NaOH to its end point?

What substance has a mass of 9.5g and volume of 2.1cm^3

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?

Rank the following four acids in order of increasing bronsted acidity : h2f+ , ch3oh, (ch3)2oh+ , ch3sh2+
