If the mass of a material is 48 grams and the volume of the material is 8 cm^3, what would the density of the material be?

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

If an atom contains 11 protons in its nucleus, predict the element with the atomic number and electronic configuration. will the number of electrons remain the same during the chemical reaction in such an atom? explain.

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.
