How would you calculate concentrations of H30 and OH? thought it was simply 10^(-pH) but I am getting a more specific number than that as the apparent answer.
In a 2 dimensional Cartesian system, the x-component of a vector is known, and the angle between vector and x-axis is known. Which operation is used to calculate the magnitude of the vector? (taken
A taxicab moves five blocks due north, five blocks due east, and another two blocks due north. Assume all blocks are of equal size. What is the magnitude of the taxi's displacement, start to finish?
A stone of mass M sits at rest on a spring near the surface of the Earth. If the spring is compressed a distance d by the weight of the stone, what is the spring constant k?

An infinitely long line of charge has a linear charge density of 4.50×10-12 C/m. A proton is at distance 19.0 cm from the line and is moving directly toward the line with speed 1900 m/s.
A car travels east at 95km/h for 0.2hours. It then travels 30.0 degrees east of north at 110km/h for 0.2hours. What is the average speed for the trip?
Explain why sodium hydroxide volumes needed to titrate the dilute nitric acid andglycolic acid are basically the same, or why they are verydifferent. Shouldn't the stronger nitric acid require more
