Explain how a seismometer works

An enzyme is participating in a general acid-base catalysis reaction with an optimal reaction pH of 6.0. If acid is added to the environment reducing the pH to 3, what is the likely impact to the rate of reaction A.

By what factor does the reaction rate change if [b] is doubled (and the other reactant concentrations are held constant) ?

In these solutions, identify the solute and the solvent Sea water, a solution composed of a variety of salts dissolved in water. The salt is the Soda water, a solution composed of carbon dioxide gas dissolved in water.

Hexane (C 6 H 14) and water do not form a solution. Which statementexplains this phenomenon? (1) Hexane is polar and water is nonpolar. (2) Hexane is ionic and water is polar. (3) Hexane is nonpolar and water is polar.

What is the volume of 2.00 moles of chlorine (cl2) gas at stp, to the nearest tenth of a liter?

A reaction of 12.640 g of copper oxide with 0.316 g hydrogen produces 2.844 g of water and Xg of copper. X=_9
