Experimental procedure, part b. three student chemists measured 50.0 ml of 1.00 m naoh in separate styrofoam coffee cup calorimeters (part b). brett added 50.0 ml of 1.10 m hcl to his solution of naoh; dale added 45.5 ml of 1.10 m hcl (equal moles) to his naoh solution. lyndsay added 50.0 ml of 1.00 m hcl to her naoh solution. each student recorded the temperature change and calculated the enthalpy of neutralization. identify the student who observes a temperature change that will be different from that observed by the other two chemists. explain why and how (higher or lower) the temperature will be different.

During chemistry class, carl performed several lab tests on two white solids. the results of three tests are seen in the data table. based on this data, carl has concluded that substance b must have bonds.

The peak wavelength for the blackbody curve of a star is in the uv range. assuming the radiation from this star can reach earth, would you be able to see it?

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
